International Comfort Products PGMD18G0605 Defrost Sensor Board
The defrost control board commences the defrost cycle which assists to keep the outdoor unit free from frost build-up. The control board is relayed information from a specific sensor which is near the condenser somewhere, in order to verify when to begin.
What to see if the outdoor defrost sensor board is about to stop working?
- Self defrost sequence does not run especially when there is frost that needs to be removed
- Your main control board could throw an error of some type referring to a failing defrost control board
- AC and heating system could cease to function due in part to way too much frost build-up
