Carrier P3 Defrost Sensor Board
The defrost control board instructs the system to activate the defrost sequence which aids to rid your unit of frost that can build up. The control board relies on a defrost sensor that can be found near the condenser, in order to decide when to initiate the defrosting cycle.
What are the signs that the Carrier defrost sensor board is about to stop working?
- Your HVAC system will not operate because of the safety features installed
- Defrost session has not run for a while even though there is quite a bit frost on the external unit
- The primary control board may show an error code if the defrost control board fails
