Lennox CB29M-46 Control Board
The control board is made to regulate the gas valve, the ignition igniter, the flame sensor as well as the air circulator all in one unit. Heating and cooling systems will not even run lest the main control board is hooked up and is correctly configured. The board that you will choose will need to be a match with your existing board and be compatible with both the make and model of your Lennox CB29M-46 unit. It is of utmost importance upon choosing a board as a replacement because of the wide variety of systems.
