Whirlpool ATE0943CPP0 Defrost Sensor Board
The defrost control board is jobbed with determining when to begin the defrosting phase which aids to rid your unit of frost that can build up. The board looks to a temperature sensor located somewhere by the condenser to verify when to begin.
How do you know when your defrost board really needs to be replaced?
- The defrost sequence never initiates even though there is a lot of frost in the way
- The main circuit board may show an error code when a defrost board fails to initialize
- Your HVAC system will stop running due to way too much frost build-up
