International Comfort Products PGS048H080F Defrost Sensor Board
The defrost control board determines when to initiate the defrost cycle in order to keep your outdoor unit from plugging up. The board depends on a sensor located in the outdoor unit to verify when to begin.
What are some indications that my International Comfort Products defrost sensor board is almost dead?
- Your system could not operate due to the frost issue
- The main board could signify an error number produced by a failing defrost board
- The defrost sequence refuses to initiate even though there is a large amount of frost on the external unit
