International Comfort Products PGF042K080A Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin the defrost sequence if necessary, to continue normal heating and cooling operations. The control board is relayed information from a defrost sensor which is near the condenser somewhere, in order to determine when to begin.
Some clues the defrost sensor board will need replacing
- The primary control board may throw an error code referring to the failed defrost sequence
- Self defrost sequence has not run for quite some time despite the fact that there is quite a bit frost in the way
- The system will stop functioning for the fact of the fact that there is too much frost
