Mitsubishi MUZ-GE15NA Defrost Sensor Board
The defrost sensor board instructs the system to activate the defrost sequence which assists to remove frost build-up that may accumulate. It relies on a sensor that can be found near the condenser, in order to verify when to initiate the defrosting cycle.
Indications the AC defrost sensor board will not last the year
- Your HVAC system will not operate for the simple fact of frost blocking the airflow outside
- The control board may throw a particular error code referring to a failing defrost control board
- Defrost mode does not begin despite the fact that there is quite a bit frost that has built up
