Trane PTED150 Defrost Sensor Board
The defrost control board is jobbed with determining when to begin the defrosting phase in order to get rid of the frost that collects on the outdoor unit. It depends on a specific sensor located somewhere by the condenser to determine when to begin.
Key indicators that my outdoor defrost sensor board is dying?
- The main control board might give out a specific error code when the defrost control board refuses to initialize properly
- Defrosting has not run for quite some time despite the fact that there is a lot of frost that has built up
- Your HVAC system will stop operating because of the frost issue
