Payne PY2PNB036060AA Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrosting phase which actually helps to rid your unit of frost that can build up. The defrost board is influenced by a specific sensor that can be found near the condenser, in order to determine when the defrost cycle should begin.
Important hints the defrost sensor board is failing
- Most systems will cease to function at all because of the safety features installed
- The control board could throw an error number when a defrost board fails to initialize
- Defrost mode refuses to run despite that there is a large amount frost on the outdoor unit
