Lennox G61MPV-36B-071 Control Board
The Lennox G61MPV-36B-071 control board is designed to command everything including the gas valve, the ignition igniter, all the various sensors and the blower all at once. Your furnace or AC will not be able to function unless this important circuit board is hooked up and is correctly configured. Be absolutely sure when you are choosing a replacement board because of the many variances of models within certain brands. The brand of board you choose will need to pair with the part number from both the brand and specific model of the unit in question.
Important clues of a poorly working main board
- The board has to be reset many times a day for it to kick in
- The unit is unwilling to initialize whatsoever
- When turned on, there is a numbered error code shown directly on the board
