Armstrong Furnace Flame Sensors

Furnace flame sensors operate to confirm to the system if a fire actually present whenever the gas valves open. If the sensor doesn’t detect any flame, it automatically shuts down the unit. Thus, it also serves as a furnace fail-safe and must always be kept in top shape.

We have a broad selection of furnace flame sensors suitably used as OEM upgraded replacement for Armstong, Ducane, Lennox gas furnace equipment.
