International Comfort Products H9MPD100J14C2 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrosting phase which assists to get rid of the frost that collects on the outdoor unit. The control board relies on a sensor that can be found near the condenser, in order to make the decision on when to initiate the defrosting cycle.
Red flags the defrost sensor board will soon need to be replaced
- The whole system may stop functioning due to lack of airflow through the outdoor unit
- Defrosting will not kick in despite the fact that there is a lot of frost in the way
- The main control board could throw a type of error code when encountering a problem
