Had it installed and running just in time for Christmas. Motor control melted on the previous board so it couldn't turn the blower on, thankfully this one came promptly on time to switch out before we left for vacation.

If your furnace goes out, check the master board before anything else. Changed my furnace board out with this new one and saved thousands. It works like a charm again.

Year later, this board still functions great. Great replacement for original Lennox G40UH-36A-070X furnace control board that was shutting off after overheating. Installation was easy, instructions were sufficient and easy to follow. This product saved me a lot's of $$. Thanks White Rodgers!

Solved my furnace issue. The furnace was turning on and off in short time intervals which overheated (burnt) some of the old board's components. New one works and has been working for an extended time without any problems.

Purchased to replaced a 32M8801 board in my Lennox unit, worked fine without any complications. A few thing to keep in mind if this is a DIY job: - This board was larger than the one I was replacing, the fit was tight and I had to re-locate the 24V transformer. Directions are also very explicit in that the board needs to be oriented upright in a specific direction. As a result your current wiring for sensors, switches, power, controls, etc may need to be spliced and extended to make the connection to the board. Not difficult or pricey, home depot has everything you need. -The 3A fuse is external to the board. Previous Lennox board had the fuse integrated but this is an external one that plugs in between the transformer and the board. -The LED status lights will likely be located in the different location from the board you are replacing. If you have a see-through hole on your unit's door it likely won't line up with the new board's LEDs. Other than those small issues it works fine. Will update if things change.
