ICM Controls ICM2813 Lennox OEM Replacement Control Board

Have an old gas furnace and had to replace a fried lennox / surelight / white-rogers system control board. (#63K8901). Check the ICM website for compatibility.The challenge was that the pin out names on the new icm2813 board did not exactly match the old (fried) board.About 50% of the wires I was able to figure out but the remaining required a call to ICM tech support. After 20mins of ICM walking me thru moving each wire from old board to new, the system was up and running like new. Can't say enough good things about ICM tech support. Bought a 2nd (back up /spare) board for any future board failures.Highly recommend icm2813 and ICM.

With the exception of the mounting plate, this was a plug and play fit for my Lennox Merit Series Furnace. The only change was moving one of the Parked Blower Motor wires to the continuous fan spade on the ICM board. I don't use continuous fan often so not a big deal. You can also jumper the fan spade over to the cool spade if you want to maintain the same fan speed for both cool and continuous fan.

Didn't work , 2 technicians tried installing it , never fired up, installed a very same board from a used furnace, from my neighbors, and worked.The board ordered was defective

Ordered it got it installed it, works great. If any problems with connecting the wires refer to the website and use the installation guide, no worries. Less money for a great product

I purchased this as a spare part in case the old one fails. I trust this new board, as many customer reviews were positive, so I bought one for backup.Further updates, on the 3/14 my old board started not working so I installed the new board yesterday and it up and running perfectly, thank you for the product

Very happy to have this control board, so my furnace works again. However, I really wish it came with diagrams for this board AND the boards it lists as a replacement for. Fortunately I was able to get help over the phone from a local furnace repair technician.

15 minutes after receiving this my furnace was up and running again. Easy to install replacement for my Lennox system that was more than half the price of the official replacement board.

The board has everything. In my case it is large that position holes on the original plate. So I have to mount included plate. One has to insert a 3/16 or 1/4 wood strip behind the plate (notice the wood strip behind thenew mounting plate) to leave a space for the mounting pins insert.Mounting plate actually takes much of the time. The wiring are different, but as long as one figures out the wire functions, then it is a straight forward process.This ICM board is cheaper than compatible Lennox or white Rodgers board.
