International Comfort Products H9MPD125L20C2 Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrost sequence which actually helps to defrost your outdoor unit. The defrost sensor board is relayed information from a temperature sensor located somewhere by the condenser to agree when to begin.
What are the indications that my defrost sensor board is about to stop working?
- The defrost sequence will not initiate especially when there is frost on the external unit
- Your main control board may signify an error code if the defrost board fails
- The system may cease to function because of lack of airflow through the outdoor unit
