Lennox CBX26UH Defrost Sensor Board
The defrost control board initiates an important defrosting cycle which may be needed in order to keep your outdoor unit from plugging up. It is relayed information from a defrost sensor that can be found near the condenser, in order to make the decision on when to begin.
How do you know if your outdoor defrost sensor board is failing?
- The primary control board may issue an alphanumeric error code when encountering a problem
- Defrost mode never begins especially when there is a rather large amount of frost on the external unit
- The system may stop running because of the safety issue that the frost poses
