Well, the products on Amazon vary wildly, I ordered this board from another company first, it came in a generic brown box with Chinese writing and basically no instructions, anyone who has used this board knows it homes in the box with a pic of board and lots of writing on the box! So I found this company and sent the other back, this showed up in 2 days, first in correct box, then if you have used this board before you know there is normally pages of big easy to read instructions, so this was a great purchase, I would recommend these guys

I was very hesitant at first and planned to return it right away if the manual isn’t as clear as it should be. Glad that the manual was made and printed like for kindergarten students. So I replaced my old ST9141A102 with this unit. It didn’t only worked, but I also noticed the difference sound of my furnace when it started and shut off. Wow! I could have spent $$$$$ to call a technician and fix my Nest e74 error.

I had ordered a control board a week ago, I tried doing exactly like their instructions said plus tried calling the tech line, it was cheap and didn’t work.That is when I ordered this name brand product. It had instructions that made clear reading and the information needed because it is a newer control board that works for my furnace but it had to be retrofitted. This product made it clear with visible and readable instructions. I highly recommend this control board and the company that sells it!!

It replaced the old version. So far everything works as supposed to be working.Definitely watch some YouTube videos before changing it by itself but it’s very easy to do it.The price was good, will get another one to keep as future replacement.

It's a near universal fit. My inducer and blower kept running. Mark all wires and swap one at a time. DI is IND (for draft inducer) All the hot wires have connections next to each other, also the neutral wires. The pin switches were set right to shut blower after 2 minutes.

This was just the ticket to solve my furnace blower issue. Only hiccup I had (and very well could be on me) was setting the dip switches via the instructions gave me a different startup delay on a/c than I had originally. Really a non issue and easily resolved.

Perfect replacement for the board in my furnace. I followed the steps given in the manual and replaced one wire after another and set the dip switches. Worked perfect. Now we have heat again.

As described. Comes with adaptors for easy quick installation. I hope I don't need another one but if I do I'd 100% buy again.
