Trane PTHD120 Defrost Sensor Board
The defrost sensor board instructs the outdoor unit to begin the defrost cycle if necessary, to keep the outdoor unit free from frost build-up. The control board depends on a temperature sensor which is near the condenser somewhere, in order to verify when to initiate the defrosting cycle.
Major signs your defrost board is in dire need of a replacement
- The main circuit board might issue an error code produced by a failing defrost board
- Defrost session will not kick in despite the fact that there is a lot of frost on the external unit
- Air conditioning may not run for the simple fact of the frost issue
