Trane GEH Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin an important defrosting cycle which assists to rid your unit of frost that can build up. The control board relies on a defrost sensor which is near the condenser somewhere, in order to make the decision on when to begin.
What warnings should I watch out for to know if my AC defrost sensor board is in need of a replacement?
- Your HVAC system will not work for the simple fact of the frost blocking the flow of air
- Your main control board may throw an error of some type when the defrost control board refuses to initialize properly
- Defrost mode never runs despite the fact that there is a lot of frost built up
