International Comfort Products GPFM60K140E Defrost Sensor Board
The defrost sensor control board initiates the defrost cycle which actually helps to keep your outdoor unit from plugging up. The defrost board depends on a sensor located near the condenser to make the decision on when the defrost cycle should begin.
Major warnings your outdoor defrost sensor board should need replacing
- The primary control board may throw an error signal if the defrost board goes out
- AC and heating system could not run due to lack of airflow through the outdoor unit
- The defrost sequence refuses to run especially when there is frost built up
