Carrier 38EYG048 Defrost Sensor Board
The defrost control board instructs the system to activate the defrosting phase which helps to keep the outdoor unit free from frost build-up. The defrost sensor board looks to a sensor located somewhere by the condenser to make the decision on when the defrost cycle should begin.
Key symptoms of an unhealthy defrost sensor board
- Self defrost sequence will not initiate even though there is a lot of frost on the unit
- The main circuit board may issue a specific error code referring to a failing defrost control board
- The HVAC system could not operate due to the fact of lack of airflow through the outdoor unit
