4T110F Thermodisc – 110°F Flush Mount Low Limit Fan Switch for Stoves & Pellet Systems

4T110F Thermodisc – 110°F Flush Mount Low Limit Fan Switch for Stoves & Pellet Systems
Maintain safe and efficient operation of your stove with the 4T110F Thermodisc. This flush mount, low-limit snap disc switch is engineered to allow power to flow to your blower only when your stove reaches optimal heating temperature—cutting off power when the stove cools down to prevent blowing cold air into your room. Ideal for wood, pellet, and corn stoves, it’s a direct replacement for many models, including the discontinued 4T120F.

Key Features:
✅ Proof of Fire Activation – Ensures the blower only runs when your stove is actively producing heat
✅ Low Limit Control – Closes at 110°F to start the blower, opens at 90°F to stop the fan when the stove cools
✅ Flush Mount Design – Saves space with easy panel integration and secure mounting
✅ Versatile Compatibility – Generic design used across multiple stove brands and models
✅ Replaces OEM Parts – Fits applications needing replacements for 80P20038-R, NBK 20159, F110-20F, and more
