Kenmore 661624670 Flame Sensor
A flame sensor is a very important part of the safety feature set that can reliably detect the acceptable flame when igniting the system. Due to safety concerns, if the sensor goes off the furnace cannot start again until the problem is repaired.
Hints your furnace flame sensor should need replacing
- The heating system will work on certain occasions whenever it pleases
- The propane or natural gas finds it impossible to start an ignition sequence and closes down
- Your system refuses to ramp up and shows an error code on the board
