International Comfort Products PGC042K080A Flame Sensor
A flame sensor is one that can reliably detect the flame during the initial ignition of the furnace. Due to safety concerns, if the flame sensor gets set off the system will halt until obstacle is corrected.
Signs of a weak primary flame sensor
- HVAC system turns on infrequently barely
- The heat system refuses to begin working when it is supposed to
- The gas that has entered the furnace has difficulty trying to properly ignite and shut down
