Payne PY1PNB036090 Defrost Sensor Board
The defrost control board initiates the defrost cycle which helps to keep your outdoor unit from plugging up. The defrost sensor board depends on a sensor located near the condenser to agree when to initiate the defrosting cycle.
What signals that my defrost sensor board is on its last leg?
- Air conditioning may cease to function for the fact of way too much frost build-up
- Your main control board could display an error signal if the defrost board goes out
- The defrost sequence never runs even though there is quite a bit frost that makes the unit run like crap
