Lennox G40UH-36A-070X Control Board
Heating and cooling systems will not even run unless this board is in place and connected. The Lennox G40UH-36A-070X control board is made to regulate the gas valve, the ignition igniter, all the sensors as well as the blower all in one unit. You must be careful while picking a new replacement board due to the many differences between brands, models and types of systems. The control board you choose will need to pair with the part number from both the brand and model of air handler system you have.
What are the clues to watch out for to know my main circuit board is on its last leg?
- The entire system has to be powered down and back up more often than not for it to run correctly
- System has lit up error code instantly appearing on the front of the control board
- Air conditioning or heating system is unable to operate well
