International Comfort Products H8MPL075B12A1 Defrost Sensor Board
The defrost sensor board determines when or if to start the defrost sequence which actually helps to keep your outdoor unit from plugging up. It is influenced by a specific sensor located somewhere by the condenser to determine when to initiate the defrosting cycle.
General warnings of an unhealthy defrost sensor board
- The defrost sequence never initiates despite the fact that there is a lot of frost in the way
- The primary control board might give out an error code produced by a failing defrost board
- Your system could end up not running due to the fact that there is too much frost
