Lennox CB29M-26 Control Board
The control board is created to control the gas valve, the ignition igniter, all the various sensors and the blower all at once. The HVAC system will be unable to operate without the board in place and connected. A replacement board must have a matching part number consistent with the brand and the model of your heating and cooling system. It is imperative that you select wisely while selecting a replacement due to the vast differences in models within certain brands.
Main clues your primary control board has little life left
- The system needs to be reset frequently for it to run
- Entire unit ceases to initialize properly
- There seems to be numbered code lit up somewhere on the circuit board
