Lennox CB30U-41 Defrost Sensor Board
The defrost control board initiates an important defrosting cycle which assists to keep the outdoor unit free from frost build-up. The defrost sensor board is relayed information from a defrost sensor that can be found near the condenser, in order to make the decision on when to initiate the defrosting cycle.
Important signs the AC defrost sensor board is in need of replacing
- Your HVAC system will end up not running because of lack of airflow through the outdoor unit
- The main circuit board could display a type of error code when the defrost board fails
- The defrost sequence will not initiate especially when there is a rather large amount of frost built up
