International Comfort Products PGMD24G0405 Defrost Sensor Board
The defrost sensor board instructs the system to activate the defrosting phase if necessary, to keep your outdoor unit from plugging up. The defrost board looks to a specific sensor located in the outdoor unit to make the decision on when the defrost cycle should begin.
What are some hints that my International Comfort Products defrost sensor board is dying?
- Most systems will end up not running at all because of the amount of frost on the outdoor unit
- Defrost session does not begin even though there is a large amount of frost on the external unit
- Your main control board may throw a particular error code produced by too much frost
