I have a cumberland model fuab100a4ob0 it's a gas furnace with a/c. The condenser unit will run but the fan blower won't run I checked the breakers they are OK .Is there some fuse to check or is there a way to by pass something to get the blower motor working .you can spin the fan by hand it turn easy. It's a holiday weekend and its hot out.
I was not able to find the cumberland companies web site for help.
Thank you
Does the fan work in heat mode?
Does it work when tstat is set for fan/fan only instead of on auto?
You need to check voltage going to the blower motor. It can be a bad thermostat, run capacitor,blower control or motor.If the blower will not run with the fan switch in the on position at the thermostat its time to get some voltage readings.
I took the blower motor wire off the board and put it into the power on the door safety switch the blower works fine. Would a bad tstat or mabe tstat wire be the problem, or do you think it's the board?thank you for your timeQuote:

Sounds like you need a new control board.
