International Comfort Products H9MPD050F12C1 Defrost Sensor Board
The defrost control board controls if and when to commence the defrosting phase which helps to rid your unit of frost that can build up. It depends on a specific sensor located near the condenser to decide when the defrost cycle should begin.
Major signs of a defective defrost sensor board
- The HVAC system control board may show a specific error code if the defrost control board fails
- The AC may not operate at all because of the amount of frost on the outdoor unit
- Unit defrost session does not begin even though there is a lot of frost built up
