Lennox G40UH-36A-045 Control Board
The Lennox G40UH-36A-045 control board is made to operate everything including the gas valve, the igniter, all the various sensors and the blower all together. It is impossible for your furnace or air handler to even activate without the board configured and seated properly. The chosen circuit board must be compatible with both the brand and model of your Lennox G40UH-36A-045 unit. You must be careful when you choose a control board because of the wide variety of models and types.
What warnings should I watch out for to know if my main circuit board is failing?
- There may be a strange type of error code lit up on the circuit board
- Air conditioning or heating system is unable to initialize correctly
- The power to the system has to be turned off and back on a lot in order to continue running
