Lennox CB30M-65 Defrost Sensor Board
The defrost control board is jobbed with determining when to begin the defrost cycle if necessary, to continue normal heating and cooling operations. The board is influenced by a specific sensor that can be found near the condenser, in order to decide when the defrost cycle should begin.
Some warnings of a worsening defrost board
- The HVAC system control board could throw a type of error code produced when the defrost control board fails to receive a signal
- Defrosting never initiates especially when there is frost on the outdoor unit
- The system may not work at all because of way too much frost build-up

If you decide on picking up or purchasing do your best and cross-check the correct model and also make a visual comparison in order to be sure the correct replacement defrost sensor board is being ordered. HVAC professionals could be quite expensive to hire so you may want to keep a lookout locally to find a good deal if you do not want to pay too much.
