Lennox Elite 14 Control Board
Your system definitely will not function without the main control board installed. The control board is constructed to control everything including the gas valve, the ignition igniter, the flame sensor as well as the air circulator all in one unit. You must do some research when you are choosing a replacement board due to so many small differences in systems. A control board that you have chosen must have a matching part number consistent with both the brand and model of your Lennox Elite 14 unit.
Major symptoms your primary control board is going to die
- AC unit or heating unit refuses to operate at all
- There seems to be a type of code instantly appearing on the circuit board
- The board needs to be reset habitually for the system to continue working
