Haier HR18D2VAR Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin an important defrosting cycle which may be necessary to keep your outdoor unit from plugging up. The control board relies on a sensor that can be found near the condenser, in order to determine when to begin.
Hints of a dying defrost board
- The defrost feature does not run despite the fact that there is quite a bit frost on the outdoor unit
- The primary control board may show an error code referring to a bad defrost board
- Your HVAC system will cease to function for the simple fact of the frost blocking the flow of air
