Trane XR15 Defrost Sensor Board
The defrost sensor board instructs the system to activate an important defrosting cycle which actually helps to continue normal heating and cooling operations. The defrost sensor board depends on a defrost sensor located near the condenser to make the decision on when the defrost cycle should begin.
Chief elements of an unhealthy defrost board
- The AC may stop operating due to the amount of frost on the outdoor unit
- The main board could display a particular error code when encountering a problem
- Unit defrost session does not begin despite the fact that there is a lot of frost that makes the unit run like crap
