Low Limit Thermodisc (80610) – 110°F Proof of Fire Snap Disc for Pellet Stoves

Low Limit Thermodisc (80610) – 110°F Proof of Fire Snap Disc for Pellet Stoves

Restore proper blower operation with this Low Limit Thermodisc (80610). Also known as a Proof of Fire (POF) switch, this snap disc closes at 110°F to signal the stove's control board that combustion has been established—activating the blower only when the stove is hot. This OEM US Stove Company part fits a wide range of Ashley, Breckwell, and USSC pellet stoves.

⚠️ Note: Some older models may require an adapter plate for installation if your existing switch has mounting holes spaced more than 1" apart. This disc may appear smaller than earlier versions but is the correct replacement.

✅ 110°F Proof of Fire Function – Confirms combustion before engaging blower
✅ Reliable Snap Disc Design – Automatically closes on rise for safe fan control
✅ Compact Size – Fits modern combustion blower housings
