International Comfort Products T9MPD080J16C1 Defrost Sensor Board
The defrost sensor board initiates the defrost sequence if necessary, to defrost your outdoor unit. The control board depends on a temperature sensor located somewhere by the condenser to decide when to initiate the defrosting cycle.
What symptoms are present when the outdoor defrost sensor board needs replacing?
- Self defrost sequence never starts especially when there is frost built up
- The primary control board could signify an error signal produced by too much frost
- Your HVAC system will not work for the fact of frost blocking the airflow outside
