Lennox CB30U-65 Control Board
Your furnace or AC will not run unless this board is in its proper place and configured for your unit. The Lennox CB30U-65 control board is designed to direct everything including the gas valve, the ignition igniter, all the sensors as well as the air circulator all at once. It is imperative that you select wisely when you choose a control board because of the wide variety of particular brands and their models. The brand of board you choose must be compatible with both the brand and model of furnace or air handler you have.
What you should see if the main circuit board is crapping out?
- AC unit or heating unit is unable to go at all
- The board has to be powered down and back up quite a lot for the furnace or AC to kick on
- System has a numbered error code indicated directly somewhere on the circuit board
