Payne PG8MAA024070AAJA Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin an important defrosting cycle which helps to keep your outdoor unit from plugging up. The defrost sensor board looks to a sensor located near the condenser to determine when the defrost cycle should begin.
Symptoms your defrost board needs to be replaced
- Self defrost sequence never begins even when there is a large quantity of frost that has built up
- The whole system may stop functioning for the fact of the amount of frost on the outdoor unit
- The main circuit board may show an error code when encountering a problem
