Lennox G40UH-60D-135 Control Board
The HVAC system will be unable to operate lest the main control board is hooked up and is correctly configured. The control board is created to operate everything including the gas valve, the ignition igniter, all the various sensors as well as the air circulator all in one unit. The chosen circuit board should be compatible with both the brand and specific model of your Lennox G40UH-60D-135 unit. It is of utmost importance upon choosing a board as a replacement due to variances between brands, models and types of systems.
Easy warnings of an unhealthy primary control board
