International Comfort Products PGC048K120F Flame Sensor
The flame sensor is only found on gas furnaces. It is a sensor that will dependably sense the correct flame during ignition. Due to safety concerns, when the flame sensor is activated the entire HVAC system will stop until the main issue is remedied.
Major clues of a poorly working safety flame sensor
- The gas furnace refuses to produce any heat at all
- The LP or natural gas finds it impossible to burn and shuts off
- HVAC system will work sporadically when it wants to
