Lennox G40UH Control Board
The Lennox G40UH control board is designed to direct everything including the gas valve, the igniter, most sensors as well as the blower all at once. The HVAC system will be unable to be able to function lest the main control board is hooked up and is correctly configured. You must do some research when you choose a control board because of the wide variety of systems. A matching board will have to match part numbers both the brand and model of furnace or air handler you have.
What happens when my main circuit board is about to go out?
- Power to the control board has to be reset quite often in order to operate
- There is some sort of error code indicated somewhere on the circuit board
- The whole unit is unable to start whatsoever
