Trane PTHD150 Defrost Sensor Board
The defrost sensor board instructs the outdoor unit to begin an important defrosting cycle which may be necessary to rid your unit of frost that can build up. The defrost board looks to a sensor located in the outdoor unit to agree when to begin.
Simple indications of an ailing defrost board
- The system may not work because of frost blocking the fins on the outside unit
- The main board might give out an error of some type if the defrost board goes out
- Defrost mode has not run for a while even though there is a large amount of frost on the unit
