Compatible Models

US Stove / American Harvest Multi-Fuel Pellet Stoves

• American Harvest 6100
• American Harvest 6220

Important: Compatibility should always be confirmed using the stove model and original circuit board part number before ordering.

Important – Does NOT Fit 6300 or 8500 Furnaces

This 80502 circuit board is NOT the correct board for the American Harvest 6300 or 8500 furnace.

If you have one of the following models:

• American Harvest 6300
• American Harvest 8500

You need US Stove circuit board part number 80554, not 80502.

Please verify your stove model before ordering.

Important Circuit Board Identification

There are important connector differences that can help identify whether this is the correct board for your stove.

US Stove 80502 Board Configuration

• This board does NOT have an RTD connection on the secondary board.
• The main board has the white "TEMP IN" connection for the thermistor.
• The secondary board has the white connector for the Plenum Temp Sensor.

We strongly recommend comparing these connections with your existing control board before ordering.

Updated 5-Fuse Circuit Board

This is the updated version of the US Stove 80502 circuit board assembly.

Earlier versions may have used a 4-fuse configuration, while this updated replacement board uses 5 component fuses.

The updated fuse configuration does not necessarily mean you have the wrong replacement board simply because your original board has fewer fuses. Verify your stove model, part number, and board connections.

Fuse Assignments

The glass fuse assignments from left to right are:

Igniter
• AGC 5 Amp
• Fast Blow

Agitator
• MDL 1 Amp
• Slow Blow / Time Delay

Exhaust
• AGC 5 Amp
• Fast Blow

Room Fan
• AGC 5 Amp
• Fast Blow

Auger
• MDL 1 Amp
• Slow Blow / Time Delay

Main Fuse

The main glass fuse is located at the bottom right of the board.

Main Fuse:
• AGC 7-1/2 Amp
• Fast Blow

What Does the 80502 Circuit Board Control?

The circuit board serves as the electronic control center for compatible American Harvest multi-fuel pellet stoves and interfaces with several important stove components and operating systems.

Depending on the stove configuration, the board controls or monitors functions associated with:

• Igniter
• Agitator
• Exhaust Blower
• Room / Distribution Fan
• Fuel Auger
• Thermistor / Temperature Input
• Plenum Temperature Sensor
• Stove Operating Controls

Because multiple stove components are controlled through the board, a control-board problem can sometimes appear to be a failure of another component.

Common Signs of a Circuit Board Problem

A failed or damaged control board may contribute to symptoms such as:

• Stove will not start or complete the startup cycle
• Igniter does not receive power
• Auger does not operate properly
• Agitator fails to operate
• Exhaust blower does not operate correctly
• Room blower fails to operate
• Intermittent stove operation
• Stove controls become unresponsive
• Components operate at the wrong time
• Visible damage or burned areas on the existing circuit board
• Repeated electrical or control-related problems

Important: These symptoms can also be caused by failed motors, sensors, wiring, switches, fuses, or other components. Proper troubleshooting is recommended before replacing the circuit board.

Before Ordering – Verify Your Board

Electronic control boards can look similar while having different connections or programming. Before ordering the US Stove 80502, verify:

• Your stove is an American Harvest 6100 or 6220
• Your replacement part number is US Stove 80502
• Your existing wiring and connector configuration matches the replacement board
• Your application uses the TEMP IN thermistor connection on the main board
• Your application uses the appropriate Plenum Temp Sensor connection
• You do not require an RTD connection on the secondary board

Do not order based solely on the physical appearance of the circuit board.

Installation & Safety

Disconnect the stove from electrical power before inspecting, removing, or installing the circuit board.

Before replacing the board:

• Unplug the stove from the electrical outlet.
• Photograph or label existing wire and connector locations before disconnecting them.
• Inspect wiring and connectors for heat damage, corrosion, or loose connections.
• Check the appropriate fuses before assuming the circuit board has failed.
• Avoid touching electronic components unnecessarily.
• Verify all connections before restoring power.

Because this is an electronic control component, professional diagnosis and installation are recommended if you are unfamiliar with pellet stove electrical systems.
