Lennox CB29M-46 Defrost Sensor Board
The defrost sensor board commences the defrost sequence which may be needed in order to keep your outdoor unit from plugging up. The control board is relayed information from a specific sensor that can be found near the condenser, in order to decide when the defrost cycle should begin.
Major signs the defrost sensor board has to be replaced
- Defrosting never kicks in even though there is a large amount of frost that makes the unit run like crap
- The HVAC system could stop operating due to way too much frost build-up
- The HVAC system control board may signify a type of error code produced when the defrost control board fails to receive a signal
