The flame sensor is an important safety feature that can sense the acceptable flame upon ignition. For obvious reasons, if the sensor goes off the gas valve is shut off and the system halts until obstacle is corrected.
Subtle hints your safety flame sensor is going out
- The whole system turns on on certain occasions when it thinks it should
- Your furnace cannot start operating and produces an error code on the circuit board
- The propane or natural gas will not properly ignite and closes the gas valve
