Modine Hot Dawg HD Terminal Board + TD Relay

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!

The replacement main board took care of the issue in my Hot Dawg garage heater.
Good price & shipped in a timely matter!!

This circuit board was easy to install, just unplugged the wires & reattach to new board. The original relay was not turning on the blower fan, so the furnace would over-heat and the limit switch would shut down the burners. The furnace works like new again ! The price for this circuit board was good, and I received it quickly. Thank you very much to ACF Greenhouses!

It works as it should.

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