Overview
Fix a stove that lights, then shuts down a few minutes later.
The proof of fire (POF) switch is a heat-sensing switch that tells the control board a fire has actually lit and is still burning. When it fails, the stove usually starts up, then shuts down or throws an ignition-failure error even though there are flames in the burn pot. This pack includes two POF switches, so you have a spare on hand.

Fitment notes: For the ComfortBilt and Alpine models listed above only; ComfortBilt does not guarantee fit on other models. The switch mounts on the exhaust or heat-exchange path, and its location varies by model, so check your stove's switch and wiring before ordering. Alpine HP41, HP42 and HP75C use the Alpine proof of fire thermocouple sensor instead.
