I've recently had to upgrade my Harman P38+ circuit board to the new 3 dial control. (Feed Adjustment, Temperature, Room/ Stove temp/Off). Now I cannot get the distribution blower to come on during operation. I can get the fire started, feed auger feeding, and the combustion blower working, but the distribution blower will not turn on during operation. I know the dist blower works because when I turn the feed adjustment dial to "test" the distribution blower, combustion blower and feed motor all turn on. I thought it may be the ESP, but even when I run on room temp mode, which I do not think uses the ESP, the motor still will not come on. Any ideas?
