Payne PY1PNB060090 Defrost Sensor Board
The defrost sensor board determines when to initiate the defrosting phase if necessary, to rid your unit of frost that can build up. The defrost board relies on a sensor that can be found near the condenser, in order to verify when to initiate the defrosting cycle.
Clues your Payne defrost sensor board is dying
- The HVAC system control board might issue an error code when encountering a problem
- Most systems will cease to function due in part to the safety issue that the frost poses
- Unit defrost session does not begin even though there is excessive frost on the outdoor unit
