Great product and even better customer service!! I would recommend this product

The replacement main board took care of the issue in my Hot Dawg garage heater.

Good price & shipped in a timely matter!!

Had my Modine go down with an Iowa cold snap coming. found ACF's website, they had stock for the control board, placed the order requesting 2nd day air. Part was received as requested. The instructions were very straight forward and with some basic mechanical skills, this part can be installed no problem.

install was easy and is working perfectly

I received this control board in a timely manner. The cost was very good and easy to install. Great company to buy from.

Easy to install. Works good.

The replacement control board worked perfectly. The directions were clear enough to make the necessary wire changes and get the unit back in service. The mounting holes for the new board do not align very well with the existing holes. However it was easy to use one screw to hod the board in place. The unit operates well and it controls the ignition and recirculating fan operation very well. Best price and quick shipping. Great value!

It works as it should.

The part i bought for my modine heater was perfect. It fixed all my problems. No problem with order, fast shipping. Will use ACF greenhouses again. Prices are reasonable too

The site was easy to use, product arrived on time, instructions were easy to follow. Very good experience.
