A furnace flame sensor is a security system that detects the presence of a flame within the furnace. If the flame goes out, the sensor will shut off the fuel provide to the furnace, stopping a fuel leak and potential explosion. It’s a essential part of your furnace’s security system.
Over time, the flame sensor can turn into soiled or coated with soot, which might intervene with its potential to detect the flame. This could result in the furnace shutting off prematurely, and even failing to start out. Cleansing the flame sensor is a straightforward activity that may be executed in a couple of minutes.
