International Comfort Products H9MPV075F12A1 Flame Sensor
The flame sensor is a safety device that can sense the exact flame when igniting the system. Because of the safety issues involved, if the sensor goes off the gas valve is shut off and the system halts until the problem is remedied and the system is reset.
Indications of a failing flame sensor
- The gas entering the furnace has a tough time trying to begin igniting and shuts off
- HVAC system will run sporadically when it feels like it
- The heating system cannot start no matter what
