Empire Comfort Systems GWT-25-2 Defrost Sensor Board
The defrost sensor board controls if and when to commence the defrosting phase which actually helps to get rid of the frost that collects on the outdoor unit. The board depends on a temperature sensor which is near the condenser somewhere, in order to make the decision on when to begin.
What are the signs that the outdoor defrost sensor board is almost dead?
- The defrost feature will not kick in despite that there is a large amount frost built up
- The main board could display a specific error code produced when the defrost board is bad
- The whole system may not work due to the amount of frost on the outdoor unit
