Whynter ARC-14S Defrost Sensor Board
The defrost sensor board initiates an important defrosting cycle which actually helps to defrost your outdoor unit. The control board depends on a sensor located somewhere by the condenser to make the decision on when to initiate the defrosting cycle.
Red flags of a barely functioning outdoor defrost sensor board
- Defrosting will not kick in even though there is excessive frost on the external unit
- The HVAC system control board might issue an error signal produced by a failing defrost board
- Most systems will not work for the simple fact of the safety features installed
