Board may not be a direct replacement, but instructions and you tube video are very well done and replacement of old board was very easy. if you are at all mechanically inclined, don't be afraid of installation. Works great. Considerably less expensive to do it yourself than have a technician install it.

It worked perfectly to replace my old 20 year old lennox control board. It popped right in and power right up and worked.

Although it was different from my original board, there was sufficient information and instructions that came with the board that help me to install. I am very happy with the product I bought. I recommend to everyone who needs to replace his old board that is apparently discontinued by Lenox.

Overall, the replacement control board works as intended. To be honest I was a little nervous because I thought I was receiving the exact control board (SureLight 32M8801). As you can see in the pic the old board was fired. When opened the package the box, the control board was different - specifically larger than the current control board. I did not panic, I just took a moment to map out all the connections on the new control board.First, I am an NOT an expert, but I am relatively handy. I simply followed the instructions that were provided. I recommend taking a picture of you current control board, so that you can reference your photo as you make the connections to the new board. Included with the new control board was a diagram and schematic that were very helpful.The control board is well made and high quality. Using the included mounting bracket, I was able to easily mount the new control board in my unit.I received the new control board a day earlier than it was projected to come, and it was well packaged. Overall, I am very pleased with product, shipping and most importantly, we have heat!

Looks like many people get different boards, but they all are compatible with the 32M8801 board which is discontinued.Although I'm happy with the board I recieved, what I dislike is that it is not advertised which specific board you're going to get, which makes it impossible to compare prices. The board I recieved is a 21D83M-843, which is shown in the images I shared, can be had for significantly cheaper than what I paid here.Besides that, this board is very easy to install. The only real difference is this new board does not have a fuse built in the board. Instead, it has an external circuit breaker. The circuit breaker goes between the blue wire that goes from the transformer and connects to another blue wire that comes off pin #3 in the 12 pin molex. All you have to do is connect the circuit breaker to the two wires as shown in the pics I provided.

Lennox single stage nat’l furnace (old system). This circuit board was a direct replacement. Just remember shut the electrical feeding furnace! Before you perform any hvac service.

Worked perfect, except I did not need the adapter pigtails
