Purchase

We purchased a circuit board for our furnace. It was delivered in 3 days. That was not the problem unfortunately, but they were very helpful in helping us diagnose the issue. I recommend this company very highly

Furnace would not heat. After a quick test with unit out of the trailer found the original board not working. Ordered the new one and it was very easy and quick to replace. Tested again and furnace lit and heated up right away

I just purchased this module for my heater and it work perfect I fit in great my heater works now, deliver was fast and easy, I will just add more protection when shipping it came on a small box with almost any wrap around it and knowing how some deliver company don’t care about packages I was a lil concern but other than that great quality product thank you

Panel in good. I didn’t need the wiring harness that was recommended to install with the card. I’ll just eat it for $ 20.00.
