Lennox XC14-036 Control Board
The control board is created to regulate the gas valve, the ignition igniter, most sensors as well as the air circulator all together. The HVAC system will be unable to operate without the control board hooked up and is correctly configured. Be absolutely sure when choosing a control board due to so many small differences in HVAC systems. The board that you will choose should have part numbers that match the brand and the model of the unit you have installed.
What are the indications that my primary control board is dying?
- The furnace or AC cannot operate whatsoever
- The power to the system has to be powered down and back up quite a lot in order to operate
- There is a fault code showing up somewhere on the circuit board
