Lennox G40DF-36A-070 Control Board
The Lennox G40DF-36A-070 control board is designed to operate the gas valve, the igniter, the flame sensor and the blower all together. The HVAC system will be unable to run at all unless the control board is configured and seated properly. The proper control board should have a replacement part number that matches both the make and model of your particular system. You should always be careful while selecting a replacement due to differences in models within certain brands.
Signs your primary control board needs to be replaced
- The HVAC system has to be reset a lot for the heating or cooling to kick in
- AC unit or heating unit does not initialize well
- There may be a strange code indicated directly on the board
