International Comfort Products GPSM42K100F Flame Sensor
The flame sensor is a very important part of the safety feature set that senses the acceptable flame during ignition. As with any other safety sensor, if the flame sensor gets set off everything stops until the problem is dealt with.
What are the indications that my flame sensor is crapping out?
- Your system cannot ramp up when the control board tells it to
- The gas entering the furnace cannot ignite no matter what you do
- The unit will run infrequently at the stroke of midnight after the second full moon following the second Sunday of the month
