The board was significantly larger than the OEM board (was for a Lennox G40U) furnace. To mount it, I had to drill a couple of extra holes to get the mounting plate to fit.Other than that, it's a very straightforward switch. I was able to use the existing Molex connectors and didn't have to use the connectors supplied with the board.The unit fired right up (the OEM board had shorted out) and ran great. Hopefully, the board will be reliable and last a long time.There were cheaper alternatives, but would have required a lot more research and diligence to ensure they were wired correctly as they are more 'universal' boards.All in all, a pretty easy replacement as it took me about an hour total (I am not an HVAC tech but an experienced DIY'er).
I installed this board, making sure I was grounded out so I wouldn't cause any static damage.Worked fine for 10 hours, then my furnace wouldn't keep running.Total waste of Money!!Giving it a 1 star rating is probably too high.
Working Great!!!! Almost exactly same Lennox G40UH (X) Series, Easy install and packaged with everything you'll need.
Only worked for 24 hours useless
Replace men is the same board.I replaced Works
it may be good for other brand but did not work for me thanks i am still waiting for scanning code to returned
I try to get my mom's furnace for winter every year and this year I replaced the control board. Just call it a hunch--I had the feeling that if I didn't do so at the time that I'd be coming back in the dead of winter to do it then. This Rendrox board allowed me to save some money over the OEM without any apparent compromise in performance. Board looks well made, fit is perfect and the 'plug and play' installation took just a few minutes. The furnance is working great and I've not had to make any 'service calls'. Solid replacement board at a value price point. Recommended!
The product looked to be exactly as what I was buying. The problem is that when I installed it, it would not ignite therefore the igniter where it plugs into the board was malfunctioning.Could not use this board after waiting a week to get it.. I live in Alaska. This time of year is cold. I am returning this item.Hopefully someone investigates this board and determines that the outlet for the igniter wire on the board does not work..
