Payne PY1PNB042060 Defrost Sensor Board
The defrost sensor board will begin an important defrosting cycle in order to remove frost build-up that may accumulate. It depends on a defrost sensor located near the condenser to agree when the defrost cycle should begin.
Warnings the AC defrost sensor board needs replacing
- The defrost sequence never initiates even when there is a large quantity of frost on the external unit
- The primary control board might issue an error code produced when the defrost control board fails to receive a signal
- AC and heating system could stop working due to the fact of the amount of frost on the outdoor unit
