Carrier 38HDR030 Defrost Sensor Board
The defrost sensor control board instructs the system to activate an important defrosting cycle if necessary, to keep the outdoor unit free from frost build-up. It depends on a specific sensor that can be found near the condenser, in order to ascertain when the defrost cycle should begin.
Elements of an ineffective outdoor defrost sensor board
- The HVAC system could not run due to the safety issue that the frost poses
- Defrost session never starts especially when there is frost that has built up
- The main control board may issue an error code produced when the defrost board is bad
