Whynter ARC-08WB Defrost Sensor Board
The defrost sensor control board controls if and when to commence an important defrosting cycle which aids to keep the outdoor unit free from frost build-up. It is relayed information from a specific sensor located somewhere by the condenser to verify when the defrost cycle should begin.
What symptoms are present when the Whynter defrost sensor board has to be replaced?
- The defrost sequence never initiates despite the fact that there is a lot of frost on the outdoor unit
- The AC may cease to function due to the fact of the frost blocking the flow of air
- The control board may issue an error of some type if the defrost board goes out
