Whirlpool ATR1555BPP0 Defrost Sensor Board
The defrost control board commences an important defrosting cycle which helps to keep your outdoor unit from plugging up. The defrost sensor board depends on a specific sensor located in the outdoor unit to decide when to initiate the defrosting cycle.
Major indications your defrost board is going out
- The primary control board may show an error number when the defrost board fails
- Self defrost sequence never initiates especially when there is a rather large amount of frost that has built up
- Your system could not run for the simple fact of frost blocking the airflow outside
