Trane TCP036F300AC Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost sequence which may be needed in order to get rid of the frost that collects on the outdoor unit. The defrost board looks to a defrost sensor which is near the condenser somewhere, in order to verify when to initiate the defrosting cycle.
Important hints the AC defrost sensor board is dying
- Defrost session never initiates even though there is a large amount of frost on the outdoor unit
- The main control board could throw an error signal produced when the defrost board is bad
- The system may stop functioning for the simple fact of the safety features installed
