Payne PA13NR04800GAAAA Defrost Sensor Board
The defrost sensor control board will determine when to initiate an important defrosting cycle which may be necessary to continue normal heating and cooling operations. The board depends on a specific sensor which is near the condenser somewhere, in order to agree when to initiate the defrosting cycle.
Signs your defrost board has little life left
- Defrost mode never begins despite the fact that there is a lot of frost that makes the unit run like crap
- Your main control board could signify an error number produced when the defrost control board fails to receive a signal
- Air conditioning may cease to function because of the amount of frost on the outdoor unit
