International Comfort Products H9MPD100J14C1 Defrost Sensor Board
The defrost control board initiates the defrost sequence which may be needed in order to keep the outdoor unit free from frost build-up. The board is relayed information from a sensor located in the outdoor unit to decide when the defrost cycle should begin.
Major signs your International Comfort Products defrost sensor board is going to die
- The HVAC system control board might give out an alphanumeric error code produced by a failing defrost board
