Panasonic CU-XE12PKUA Flame Sensor
The flame sensor is a safety feature that will dependably sense the precise flame while the system is starting. As with other safety devices, if the flame sensor gets set off everything remains shut off until the problem is dealt with.
Some clues the primary flame sensor needs replacing ASAP
- Your system refuses to begin working and will shut everything down
- HVAC system will sometimes work sometimes at the stroke of midnight after the second full moon following the second Sunday of the month
- The gas supplying the furnace cannot begin an ignition sequence and closes the gas valve
