Carrier 38H Defrost Sensor Board
The defrost sensor board commences the defrosting phase which actually helps to defrost your outdoor unit. The defrost sensor board is relayed information from a temperature sensor which is near the condenser somewhere, in order to determine when the defrost cycle should begin.
Major clues your outdoor defrost sensor board is in dire need of a replacement
- The defrost feature never runs especially when there is a rather large amount of frost that has built up
- Most systems will not operate for the simple fact of way too much frost build-up
- The HVAC system control board could signify a type of error code when encountering a problem
