• Match the motor to your specific appliance: The right replacement isn't just one that fits—it's one with the correct RPMs and power rating for your stove or grill model. Getting these details right is the key to consistent heat and reliable performance.
• Install with care and maintain for longevity: A successful replacement depends on careful installation—ensure the motor shaft is perfectly aligned to prevent noise and damage. Afterward, simple habits like keeping the hopper clean will protect your new motor and help it last for years.

What Does an Auger Motor Do?

If you’ve ever wondered what makes your pellet stove or grill work so consistently, the answer is the auger motor. This small but mighty component is the key to automated, steady heat. Understanding its role is the first step in figuring out if yours needs a replacement and how to tackle the job yourself. It’s a straightforward part, and once you know what it does, troubleshooting becomes much easier.

The Heart of Your Pellet Grill or Stove

Think of the auger motor as the heart of your pellet stove or grill. Its main job is to feed fuel—the wood pellets—into the burn pot where the fire happens. This isn't just a random dump of pellets; the motor ensures a steady, controlled supply. This consistent flow is key to maintaining an even temperature and getting the most efficient, clean burn from your fuel. When your auger motor is working correctly, you get reliable heat without having to constantly adjust settings. It’s the unsung hero that keeps everything running smoothly behind the scenes.

A Quick Look at How It Works

So, how does it actually do its job? It’s pretty simple. The auger motor turns a long, corkscrew-shaped rod called an auger. This auger sits inside a tube that connects the pellet hopper (where you store the pellets) to the burn pot. As the motor spins the auger, the pellets are slowly and consistently pushed along the tube and dropped into the fire. If the motor starts to fail, it can’t turn the auger properly. You might notice the auger getting stuck or "binding," which messes up the pellet feed and can cause problems with your stove's performance.

Is Your Auger Motor Failing? Watch for These Signs

Your auger motor is one of the hardest-working parts of your pellet stove, but it won’t last forever. When it starts to wear out, it usually gives you a few clear warning signs. Learning to spot these clues can help you diagnose the problem quickly and avoid a complete breakdown when you need your stove the most. If you notice any of the following issues, it might be time to inspect your auger motor and consider a replacement.

Strange Noises: Grinding, Squealing, or Whining

One of the first signs of a failing auger motor is a sudden change in the sounds it makes. You’re probably used to the gentle hum of your stove, so any new, unpleasant noises should get your attention. Grinding sounds often point to wear and tear on the motor’s internal gears or shaft. You might also hear a high-pitched squealing or whining, which can indicate that the motor's bearings are failing. Before you assume the worst, it’s a good idea to check for debris or a simple jam, but persistent mechanical noises usually mean the motor itself is on its last legs.

Inconsistent or Slow Pellet Feeding

The auger motor’s main job is to deliver a steady, consistent supply of pellets to the burn pot. If you notice your fire is struggling to stay lit or the temperature keeps dropping, it could be due to an inconsistent pellet supply. A dying motor may start to turn more slowly or intermittently, failing to keep up with the stove's fuel demand. This can result in a weak, inefficient fire and fluctuating heat output. While a pellet jam can cause similar symptoms, a motor that is visibly turning slower than usual is a strong indicator that it’s beginning to fail.

The Motor Won't Turn On at All

The most obvious sign of a problem is when the auger motor stops working completely. If you don’t hear it running and see no pellets being fed into the burn pot, the motor may have failed. Before you jump to conclusions, always check the simple things first. Make sure your stove is plugged in and that you haven’t tripped a circuit breaker. Sometimes, the issue isn't the motor but the control board that sends it power. However, if the power supply is fine and the motor is completely unresponsive, it has likely burned out. At this point, a new motor is your best solution.

It Feels Hot to the Touch

It’s normal for an auger motor to feel warm during operation, but it should never be too hot to touch. Excessive heat is a major red flag that the motor is under serious strain and working too hard. This can be caused by an internal short, failing bearings, or an imbalance from an improper installation. If you carefully check the motor housing and find it’s extremely hot, shut down your stove immediately to prevent further damage to the motor and other components. An overheating motor is a fire hazard and a clear sign that it needs to be inspected and likely replaced.

How to Know for Sure It's the Motor

So, you suspect your auger motor is on the fritz. Before you jump to buying a replacement, it’s smart to do a little detective work. Sometimes, what looks like a dead motor is actually a much simpler (and cheaper) fix. Running through a few quick diagnostic steps can save you time, money, and the frustration of replacing a part that wasn't even broken. Let's walk through how to confirm that the motor is truly the culprit.

First Things First: Safety

Before you touch a single screw or wire, your number one priority is safety. Always unplug your stove or grill from the power source before you start any inspection or repair. This isn't just a friendly suggestion—it's a critical step to prevent electrical shock. Working with electrical components requires your full attention and caution. If at any point you feel unsure or uncomfortable with what you’re doing, please stop and call a local service professional. There’s no shame in asking for help, especially when your safety is on the line.

Test the Motor's Function

One of the most direct ways to test your motor is to see if it runs when it's supposed to. Many pellet stoves and grills have a "prime" or "feed" button that manually runs the auger. Try activating this function. If the auger is turning OK in prime mode, then the motor should be fine, and the problem might be with a sensor or the control board. If you hear the motor trying to work—a low hum, for example—but the auger doesn't move, it could be jammed or the shear pin might be broken. If you hear nothing at all, it points more strongly toward a failed motor or a wiring issue.

Check for Jams and Blockages

An auger jam is a common issue that can easily be mistaken for a broken motor. If the auger can't turn, the motor can't do its job. The first thing to do is completely empty the pellet hopper. Once it's empty, use a flashlight to look down into the auger chute for any obstructions. Clumped or wet pellets, dust buildup, or even a foreign object can create a solid blockage. Use a shop vac to clean out any debris. A jam puts a lot of strain on the motor, and clearing it might be all you need to get things running again.

Inspect the Shear Pin and Wiring

If the auger is clear but still won't turn, the next thing to check is the shear pin. This small pin connects the motor to the auger shaft and is designed to break under extreme stress to protect the motor from burning out. You may need to remove a cover plate to access it. If the pin is snapped, the motor will run, but it won't be able to turn the auger. Replacing a shear pin is a simple and inexpensive fix. While you're there, give the wiring a quick visual inspection. Look for any loose, disconnected, or frayed wires connected to the motor. If everything else checks out, it’s a strong indicator that you need a new auger motor.

Find the Right Replacement Auger Motor

Once you’ve confirmed that your auger motor is the culprit, the next step is finding the right replacement. This might feel a little daunting with all the different parts and specs out there, but it’s simpler than it looks. Getting the right part ensures your stove or grill runs efficiently and saves you the headache of a poor-performing appliance. Think of it as finding the perfect puzzle piece—it needs to fit just right.

To make sure you get the correct one, you’ll want to pay attention to three key things: the brand and model of your appliance, the motor’s RPMs, and its power rating. Let’s walk through what each of these means so you can confidently choose from our selection of motors and get your pellet stove or grill working like new again.

Match the Motor to Your Grill's Brand and Model

The most important step in this process is ensuring the new motor is compatible with your specific grill or stove. Different brands and models are designed to work with particular motors, and a mismatch can lead to poor performance or even damage. Start by checking your owner's manual or looking for a label on the appliance itself to find the exact brand and model number. This information is your best friend when shopping for a replacement. Many popular pellet grill brands have specific motor requirements, so confirming compatibility upfront will save you a lot of trouble.

Understand the Specs: RPMs and Ratings

Next, you’ll want to look at the motor’s RPM, which stands for "rotations per minute." This number tells you how fast the auger will turn, which directly controls how many pellets are fed into the firepot. A motor with the wrong RPM can either starve the fire or overwhelm it with too much fuel, leading to temperature swings. The most common speed for pellet grills is 2.0 RPM, but it’s always best to verify the requirement for your specific model. Getting the RPM right is key to maintaining a consistent, steady heat for that perfect cook.

Check the Power and Amperage

Finally, take a look at the power and amperage (amp) rating. Think of this as the motor’s strength. A motor with a higher amp rating is generally more powerful and durable, capable of handling the workload without straining. For example, some heavy-duty replacement motors have a 0.5 amp rating, giving them a bit more muscle than standard options. Choosing a motor with adequate power ensures it can turn the auger smoothly, even when the hopper is full, and contributes to a longer lifespan for the part. It’s a small detail that makes a big difference in long-term performance.

Your Replacement Motor Options

Once you’ve confirmed that your auger motor is the problem, your next task is to find a suitable replacement. You have a few paths you can take, and the right one depends on your stove or grill model, your budget, and whether you’re looking for a simple replacement or a performance upgrade. The market is full of options, from parts made by your original manufacturer to high-quality aftermarket alternatives that can offer excellent value and reliability.

Making the right choice comes down to understanding what you need. It’s about more than just finding a part that fits; you want a motor that will restore your appliance’s function and keep it running efficiently for years to come. We’ll walk through some of the most common scenarios and what to look for, whether you own a popular grill brand or are looking for a universal fit. This will help you select a new motor with confidence, knowing it’s the perfect match for your equipment.

Why Choose a Total Hearth Motor

Finding a Match for Traeger Grills

If you own a Traeger grill, finding a compatible auger motor is a common repair. Many replacement motors are designed to fit a wide range of popular wood pellet smokers, including most Traeger models (with a few exceptions like the PTG). These

Finding a Match for Pit Boss Grills

Pit Boss owners also have straightforward options when it comes to motor replacement. Because Pit Boss is a popular brand, you can often find replacement parts designed specifically for their various series. For instance, the "Auger Motor - PB 2 RPM Series" is a direct replacement for many of their grills. Using a model-specific part like this takes the guesswork out of the repair, as you can be confident it will fit correctly and perform as expected. Always start by identifying your grill's model number to find the exact motor you need.

OEM vs. Aftermarket: What's the Difference?

As you shop, you’ll see the terms "OEM" and "aftermarket." OEM stands for Original Equipment Manufacturer, meaning the part is made by the same company that made your stove or grill. Aftermarket parts are made by a third-party company. OEM parts guarantee a perfect match, but they can be more expensive. High-quality aftermarket motors, on the other hand, can offer the same reliability and performance—sometimes even better—at a more accessible price point. The key is to buy from a trusted supplier that stands behind their products and offers parts specifically designed for your appliance model.

Where to Buy a Replacement Motor (and What to Expect to Pay)

Once you’ve confirmed the auger motor is the problem, the next step is finding a replacement. You have a few options for where to shop, and the price can vary quite a bit depending on what you need. Knowing where to look and what a fair price is will help you get your stove or grill back up and running without overspending. Let’s walk through what you can expect.

Buying Online vs. In-Store

Shopping online is often the most convenient way to find a replacement motor. You’ll find the widest selection, from massive retailers to specialty suppliers. The main advantage is variety; you can compare different brands and prices from the comfort of your home. Here at Total Hearth, we carry a curated selection of high-quality motors designed to fit a range of models, taking the guesswork out of finding a compatible part.

Of course, there’s something to be said for buying from a local hardware or specialty stove shop. You can get hands-on advice from an expert and walk out with the part you need the same day. The trade-off is that their inventory might be limited to the most common models. Your best bet depends on how quickly you need the part and how confident you are in choosing the right one yourself.

A Look at Typical Costs

The cost of a replacement auger motor can range from around $30 to well over $100. This price difference comes down to a few key factors: the brand of your appliance, the motor’s specifications (like its RPM), and whether you’re buying an original equipment manufacturer (OEM) part or an aftermarket one. For example, a replacement motor for a popular grill brand might be on the lower end, while a more specialized or powerful motor will naturally cost more.

While it’s tempting to go for the cheapest option, remember that this part is the heart of your appliance. Investing in a quality motor that’s a perfect match for your unit will ensure it runs efficiently and reliably for years to come. Always prioritize compatibility and quality over saving a few dollars upfront.

Don't Forget the Warranty

A good warranty is a sign that the manufacturer stands behind its product. Before you make a purchase, always check the warranty details. This protects you in case the motor is defective or fails prematurely. Some brands offer excellent coverage; for instance, certain Pit Boss grills come with a multi-year warranty that may cover parts like the auger motor.

Whether you buy an OEM or aftermarket part, look for at least a one-year warranty. This gives you peace of mind and shows that the company has built a product designed to last. Read the fine print to understand what’s covered and what the replacement process looks like, just in case you ever need to use it.

How to Replace Your Auger Motor: A Step-by-Step Guide

Replacing an auger motor might sound intimidating, but it’s a manageable job with the right tools and a clear plan. Think of it as a straightforward swap: one part out, one part in. Taking the time to do it correctly will get your stove or grill running smoothly again and save you the cost of a professional service call. We’ll walk through the entire process together, from gathering your supplies to firing up your appliance to test your handiwork. Just follow these steps, and you’ll have that new motor installed in no time.

Gather Your Tools

Before you get your hands dirty, let’s make sure you have everything you need. There’s nothing more frustrating than having to stop mid-project to hunt for a tool. For this job, you’ll likely need a socket set (a 5/16" is common), a Phillips head screwdriver, and an Allen wrench. It’s also a good idea to have a pair of wire cutters or strippers handy for the electrical connections. And, of course, grab a pair of work gloves to protect your hands. Having these items ready will make the entire process much smoother.

Safety Check Before You Start

This is the most important step, so don’t skip it. Your safety is the top priority. Before you do anything else, completely unplug your pellet stove or grill from its power source. Don’t just turn it off—unplug it from the wall. Next, make sure the appliance has had plenty of time to cool down completely. Working on a hot stove is a recipe for burns and other accidents. Once the unit is unplugged and cool to the touch, you’re ready to get started on the replacement.

Step 1: Remove the Old Motor

First, open the service panel to get access to the motor area, which is usually located under the pellet hopper. Before you unbolt the motor, take a quick look at the shear pin; sometimes this small pin breaks to protect the motor, and it’s a much easier fix. If the pin is fine, it’s time to remove the motor. I recommend taking a quick photo of the wiring with your phone so you have a reference for later. Carefully disconnect the wires for the motor and any other nearby electrical components like the igniter or fan. Then, use your socket set or Allen wrench to remove the bolts holding the old motor in place and slide it out.

Step 2: Install the New Motor

Now it’s time to install your new auger motor. Slide it into position, making sure the small flat spot on the motor’s shaft lines up perfectly with the set screw on the auger. This alignment is critical—if it’s not right, the auger can slip, make grinding noises, or damage the new motor. Once it’s aligned, tighten the set screw firmly. Then, re-secure the motor with its mounting bolts. Using the photo you took earlier as a guide, reconnect the wires. Take your time to ensure each connection is secure.

Step 3: Test Your Work

With the new motor installed and all the wires reconnected, it’s time for the moment of truth. Close up the service panel, plug your stove or grill back in, and turn it on. Listen carefully as it starts up. You should hear the motor running quietly and see pellets feeding smoothly into the burn pot. If you hear any binding or grinding noises, turn the unit off immediately and unplug it. You may need to go back in and double-check the auger’s alignment. A smooth, quiet operation means you’ve successfully completed the job.

Common Mistakes to Avoid

Replacing an auger motor is a totally manageable DIY project, but a few common slip-ups can turn a simple fix into a major headache. Taking a little extra time to do things right the first time will save you from having to do it all over again. Let's walk through the three biggest mistakes people make so you can get your stove or grill running perfectly without any extra stress.

Skipping the Diagnosis

When your stove stops feeding pellets, it’s tempting to assume the motor is dead and immediately order a new one. But hold on—playing detective first can save you time and money. A proper diagnosis ensures you’re fixing the actual problem. For instance, grinding noises before a failure often point to wear on the motor’s shaft or gears, but they could also mean seized bearings or debris. Before you replace the whole unit, inspect the motor and check the related electrical components for issues. You might find that the motor itself is fine and another part is the real culprit.

Installing It Incorrectly

You’ve got the right part and you’re ready to install it. The key here is patience and precision. Rushing the reassembly can lead to problems that are tricky to pinpoint later. If the new motor is noisy or isn't working, it’s very likely something wasn't seated properly or one screw was over-tightened, creating an imbalance. To avoid this, take photos as you disassemble the old motor to guide you. When you install the new one, make sure everything is perfectly aligned and tighten screws evenly. A correctly installed motor will run quietly and last for years.

Forgetting to Clear the Auger Tube

This might sound basic, but you’d be surprised how often it’s overlooked. Before you even think about putting the new motor in, you have to completely clean out the auger tube. As one expert puts it, the first thing you should do is "empty out the hopper [and] make sure there's no obstructions in the auger itself." Leftover pellets, dust, or a foreign object can jam your brand-new motor before it even gets a chance to work properly. Imagine the frustration of finishing the job only to have it fail immediately. A quick clean-out prevents this and ensures a smooth start for your new motor.

Keep Your New Motor Running Smoothly

Now that you’ve installed your new auger motor, you want it to last as long as possible. The good news is that a little preventative care goes a long way. You don’t need to be a mechanical expert to keep your stove or grill in top shape. By building a few simple habits into your routine, you can protect your investment and ensure your auger motor operates efficiently for years to come. It all comes down to three key areas: creating a simple maintenance schedule, knowing how to spot potential issues before they become big problems, and storing your appliance correctly during the off-season. Taking these steps will save you time, money, and the headache of another replacement down the road.

Create a Simple Maintenance Routine

Think of this as a quick health check for your stove. At least once a month during peak season, take a few minutes to look things over. Start with the pellet hopper. If you see dust or pellets that look swollen, it’s a sign that moisture has gotten in. Vacuum out the old pellets to prevent them from jamming the auger and straining the motor. While you’re there, make sure the auger tube is clear of any debris. A clear path means the motor doesn’t have to work as hard. Finally, check the seals and gaskets on your appliance. A tight seal keeps moisture out and helps your stove run efficiently, which benefits every component, including your new motor.

How to Prevent Future Problems

The best way to avoid a major repair is to catch small issues early. Your ears are one of your best tools for this. If you start to hear grinding, squealing, or whining sounds, don’t ignore them. These noises often indicate that the motor’s shaft or gears are wearing down. It’s a clear signal to inspect the motor for any blockages or seized bearings before it fails completely. A quick visual check now and then can also make a huge difference. Look for any debris buildup around the motor that could cause it to overheat or jam. Being proactive means you can address a minor issue before you’re left in the cold and need to order new motors all over again.

Tips for Off-Season Storage

When the weather warms up and you’re done using your stove for the season, a little prep work can prevent a lot of problems next fall. First, completely empty the pellet hopper. Leaving pellets in the hopper for months is a recipe for moisture absorption, which can lead to clumps that will jam the auger when you start it up again. Next, give your appliance a thorough cleaning. Remove all the ash from the burn pot and clean out the auger tube. This prevents corrosion and ensures all the electrical components are free from damaging buildup. Finally, if possible, cover your stove or grill to protect it from dust and humidity. A clean, dry environment is the key to a long and healthy life for your auger motor.

Frequently Asked Questions

My pellets aren't feeding, but I hear a humming sound. Is the motor broken? A humming sound without any movement is a classic sign that the motor is trying to work but something is stopping it. Before you decide the motor is dead, unplug your stove and check for a jam. Completely empty the pellet hopper and use a vacuum to clear out any clumped pellets or debris from the auger tube. If the path is clear, the next thing to inspect is the shear pin, a small part designed to break under stress to protect the motor. If both the tube and pin are fine, then it's likely the motor itself has failed.

Can I use a motor with a different RPM than my old one? It's always best to stick with the RPM, or rotations per minute, that your stove or grill manufacturer recommends. This speed is specifically calibrated to deliver the right amount of fuel to maintain stable temperatures. Using a motor that's too fast can overwhelm the fire with pellets, while one that's too slow can starve it, causing frustrating temperature swings. You can usually find the correct RPM listed in your owner's manual or printed on a label on the old motor.

Is an aftermarket motor as good as one from the original manufacturer? Absolutely. A high-quality aftermarket motor from a trusted supplier can be just as reliable as an OEM (Original Equipment Manufacturer) part, and often at a more accessible price. The most important thing is to ensure the replacement part's specifications, like RPM and power rating, match what your appliance requires. As long as you choose a motor that is designed to be compatible with your specific model, you can expect great performance.

I just installed my new motor and it's making a grinding noise. What's wrong? A grinding noise right after installation almost always points to an alignment problem. The motor's shaft has a small flat spot that must line up perfectly with the set screw on the auger. If this alignment is even slightly off, the parts will grind against each other. You'll need to unplug the unit, loosen the set screw, and carefully adjust the motor's position until it is seated perfectly. Once it's properly aligned and tightened, it should run quietly.

What's the most important thing I can do to make my new motor last? The single best thing you can do is keep the entire fuel path clean. This means regularly vacuuming pellet dust out of the hopper and, most importantly, never leaving pellets in the hopper during the off-season. Pellets left for long periods can absorb moisture and form clumps that will jam the auger. A clean, clear path ensures the motor doesn't have to strain, which is the key to a long and efficient life.
