Whirlpool ATR0753CPP0 Defrost Sensor Board
The defrost control board initiates the defrost sequence which helps to keep your outdoor unit from plugging up. The board relies on a specific sensor that can be found near the condenser, in order to verify when the defrost cycle should begin.
Red flags your defrost board has to be replaced
- Your main control board may show an error signal referring to a bad defrost board
- Defrosting never initiates even though there is quite a bit frost on the external unit
- The system may end up not running because of the frost blocking the flow of air
