Whirlpool ATE1555BPP0 Defrost Sensor Board
The defrost control board will determine when to initiate the defrost sequence which actually helps to rid your unit of frost that can build up. It is influenced by a defrost sensor which is near the condenser somewhere, in order to determine when to begin.
Important hints your outdoor defrost sensor board is not going to last much longer
- Defrosting does not begin despite the fact that there is quite a bit frost on the outdoor unit
- Your main control board might give out an error code when a defrost board fails to initialize
- The whole system may stop functioning for the fact of frost blocking the fins on the outside unit
