Carrier 38BYC030 Defrost Sensor Board
The defrost sensor board controls if and when to commence an important defrosting cycle which may be needed in order to continue normal heating and cooling operations. The defrost sensor board looks to a temperature sensor which is near the condenser somewhere, in order to ascertain when to begin.
Some clues the AC defrost sensor board should need replacing
- Your main control board might issue an error number produced by a failing defrost board
- The system may cease to operate due to the fact of lack of airflow through the outdoor unit
- The defrost feature never starts especially when there is a rather large amount of frost on the outdoor unit
