Lennox G40DF-48C-090 Control Board

The HVAC system will be unable to be able to function without the main control board configured and seated properly. The Lennox G40DF-48C-090 control board is made to control the gas valve, the igniter, most sensors and the blower all together. You must do some research when choosing a control board due to variances between models and types. The selected board must be compatible with both the brand and specific model of furnace or air handler you have.
