Whirlpool ATE1545BPP0 Defrost Sensor Board
The defrost sensor board instructs the system to activate the defrost cycle which may be necessary to rid your unit of frost that can build up. The control board is influenced by a sensor located somewhere by the condenser to agree when the defrost cycle should begin.
Simple indications of a poorly working defrost board
- AC and heating system could end up not running for the simple fact of the safety issue that the frost poses
- The main circuit board could throw a specific error code produced by too much frost
- Defrost session never runs even though there is a large amount of frost that makes the unit run like crap
