Lennox CB30M-46 Control Board
The Lennox CB30M-46 control board is created to operate everything including the gas valve, the ignition igniter, the flame sensor as well as the air circulator all together. Your system definitely will not operate whatsoever lest the main control board is properly connected to the unit. Be very careful when you choose a control board due to so many small differences in HVAC systems. Any control board you choose will have to be compatible with both the brand and model of the unit in question.
Simple indications of a barely functioning control board
- The whole unit is not able to start period
- The HVAC system needs to be reset many times a day for it to kick in
- Could be an numbered code being displayed on the control board
