Furnace lights but blower doesn't activate
Posted: Sat Nov 17, 2012 8:32 pm
I have an Evcon DGAT095ADA furnace. When the thermostat calls for heat a small exhaust fan kicks on then the burner egnites, this is all that happens. The large blower fan to the house does not activate. The smaller exhaust? fan will run for hours. To get the furnace to run, I have to actuate the manual on-off-auto switch a few times and give the circuit board cover area a few taps. After this the furnace will run normally for a day or so. I don't have any user, troubleshooting, or parts manuals.
Thanks for your help,
Dave
