Whirlpool ATR1253CPP0 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin an important defrosting cycle in order to defrost your outdoor unit. The board is relayed information from a specific sensor located in the outdoor unit to determine when the defrost cycle should begin.
Subtle cues of a failing Whirlpool defrost sensor board
- Unit defrost session never begins despite the fact that there is quite a bit frost that makes the unit run like crap
- Air conditioning may not work due to the fact of too much frost
- The main control board may throw an error code if the defrost board fails
