Purchased this board 2 times in 3 weeks for half the cost that Grainger would charge me. Each one was brand new and worked as it should plus had the upgraded external mount indicator light. Shipping was pretty much as expected and I will order from ACF Greenhouses.com again. Never heard of this place before but was willing to take the chance based on reviews. Great choice.

Great price, fast shipping, good instructions on board changes. 5 Stars

It fixed my issue. I really like the extended status light, it is nice to have it visible with out taking the side cover off.

Easy replacement for the original. Read the instruction sheet before starting the install. Some of the terminals move to a different location.

I had a tech in who did not identify the board as the issue with the furnace. The repair did not work, but on a recommendation from a friend I decided to replace the control board. Price here was much better and the directions made it a simple swap. Thanks!
