International Comfort Products CHP448AKA1 Flame Sensor
A flame sensor is a vital part that can reliably detect the exact flame during the initial ignition of the furnace. 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 dealt with.
Symptoms of a deteriorating primary flame sensor
- The entire heating system works infrequently only after the second full moon of the month on a Tuesday
- The type of gas you use has problems trying to begin an ignition sequence and the board throws an error
- The gas furnace is unable to produce heat when you crank the thermostat up
