Worked great, instructions were clear and concise. Delivery was sooner than expected.

Very happy with the whole experience.

Received parts when expected and had my furnace up and running in an hour.

My garage unit heater began working sporadically. I narrowed down to a loose connection on one of the plugs. After a Google search I found it here at the lowest price. Since overnight temps were warming up I thought I should be able to get by for a week without heat. Since I do not have a basement I keep things in the garage that cannot freeze.

Ordering was simple and straight forward. The board came way earlier than I expected (three days I think) and was packaged very well. At first I was concerned I ordered the wrong part as it was different than the original but after reviewing the included instructions and photos I realized it was an updated model. Installation was simple and once all the connections were made it worked flawlessly. The instructions and photos were amazing compared to what usually comes with Chinese products. Happy customer. I would recommend this company to anyone.

This order shipped and delivered on time. It was a direct replacement for the control board in my hanging heater and fixed the issue I was having. There were some changes to the control board and it came with a set of printed instructions with pictures explaining how to hook it up and the changes.

Fast shipping

Received in good time and worked as it should. Second time ordering this item for 2 different units. Cost almost half of what Grainger charges.

Our order arrived in a timely manner. This was very important to the project at hand.

Replaced heater control board. Switching out boards was very easy with included wiring revision. Heater working like new.

Great price and fast shipping on this hard to find Sterling/Beacon control board.

This is an upgraded OEM board now with a remote fault code light so if there is a problem we don't have to set up a ladder to see the fault. Several major manufacturers sell rebadged Sterling/Beacon heaters such as Trane and ICP. I'll definitely do business with ACF Greenhouses again.

Service, shipping and product are all excellent!
