Whirlpool ATE0955CPP0 Defrost Sensor Board
The defrost sensor board controls when to launch the defrost sequence which aids to continue normal heating and cooling operations. It relies on a defrost sensor located in the outdoor unit to agree when to initiate the defrosting cycle.
What happens when my defrost board is not working properly?
- The system may stop working due in part to frost blocking the airflow outside
- The defrost sequence refuses to initiate despite that there is a large amount frost that makes the unit run like crap
- The main circuit board could throw a particular error code produced when the defrost board is bad
