Lennox CB27UH-048 Control Board
The Lennox CB27UH-048 control board is made to oversee everything including the gas valve, the ignition igniter, the flame sensor as well as the air circulator all in one unit. Most systems will not run at all without the control board correctly installed. Be absolutely sure when you are deciding on a replacement due to so many small differences in particular brands and their models. The board you choose should have part numbers that match both the brand and model of furnace or air handler you have.
What are the clues to watch out for to know my Lennox control board is on its last leg?
- Your system ceases to initialize correctly
- System has a strange code being displayed on the front of the control board
- Everything has to be powered down and back up often for the system to continue working
