Payne PA2PNB024000AA Defrost Sensor Board
The defrost control board initiates an important defrosting cycle which assists to rid your unit of frost that can build up. The defrost sensor board relies on a sensor located in the outdoor unit to verify when the defrost cycle should begin.
What red flags are there that my Payne defrost sensor board is in need of a replacement?
- The primary control board may issue a specific error code when a defrost board fails to initialize
- Defrost mode will not initiate especially when there is frost built up
- The system may cease to operate because of too much frost
