Whirlpool ATR1242BPP0 Defrost Sensor Board
The defrost control board will begin the defrosting phase in order to keep your outdoor unit from plugging up. The defrost sensor board relies on a specific sensor located in the outdoor unit to decide when to begin.
How can I tell if my Whirlpool defrost sensor board is not working right?
- The system may not operate due in part to lack of airflow through the outdoor unit
- Defrost mode never initiates despite the fact that there is quite a bit frost that makes the unit run like crap
- The HVAC system control board could signify a specific error code referring to the failed defrost sequence
