International Comfort Products PGMD42G0604 Defrost Sensor Board
The defrost sensor board will determine when to initiate the defrosting phase if necessary, to continue normal heating and cooling operations. The control board is influenced by a sensor located near the condenser to decide when to begin.
Some clues the defrost sensor board is going out
- The whole system may stop operating at all because of the fact that there is too much frost
- The main control board may signify a specific error code produced by a failing defrost board
- Unit defrost session refuses to initiate despite the fact that there is a lot of frost that has built up
