International Comfort Products PGMD42H060A Defrost Sensor Board
The defrost sensor board controls when to launch the defrost cycle if necessary, to get rid of the frost that collects on the outdoor unit. It relies on a specific sensor located near the condenser to make the decision on when to initiate the defrosting cycle.
Major indications of a poorly performing defrost board
- Unit defrost session never starts especially when there is frost built up
- The system may not operate due to the safety issue that the frost poses
- The main circuit board could signify an error number referring to the failed defrost sequence
