Lennox 10ACB Control Board
It is impossible for your furnace or air handler to even be able to function without the control board properly connected to the unit. The control board is constructed to control everything including the gas valve, the igniter, all the various sensors as well as the air circulator all at once. You must do some research while selecting a replacement due to the many differences between brand and air handler types. The chosen circuit board will have to be compatible with both the brand and model of your Lennox 10ACB unit.
Important clues of a bad Lennox control board
- The system has to be powered down and back up all the time in order to operate
- There may be an error code being displayed on the circuit board
- Entire unit does not operate at all
