    Great service

    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.

    Worked great

    Fixed my hot dawg garage heater that had issues where the blower fan wasn’t coming on.

    Modine Hot Dawg Control Board

    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!

    Fixed my garage heater

    Good price & shipped in a timely matter!!

    Modine Hot Dawg Terminal Board & TD Relay

    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!
