I have a coleman furnace 7970-856 in my mobile home and the blower motor is having problems . It is barley turning and I can give it a push and it takes off sometimes and other time it won't what can I check for to see what's wrong
when a blower motor is starting to break/stop working it will have trouble starting and give a humming noise. when you give it that push start you assist it past that sticking point. i would give the fan a push start and turn the summer fan on to keep it running all the time to avoid the start/stop, then either install a new motor or call a furnace service company to replace the motor.
