Furnace blower motor not switching off
I have an old furnace and a new central a/c unit. The other night I realized the blower motor was not shutting off when the thermostat clicked off the a/c. I had to unplug the blower motor . The next day I installed a new thermostat to see if that was the problem. It was not. The blower motor was replaced about 4 years ago, but it looks old so it probably was a rebuilt one. We previously leased the house and are now buying it. The motor is a Varitrol motor--model-59066SL.
I had a blower fan shut off problem,
My Lenox, from 1989 would not shut off and the problem was the fan limit control, my particular box takes one with a power line on it, the heating guy replaced it twice and mistakenly grabbed the wrong one because they look identical, but one has a hot wire on it, with the correct one in the unit the fan works fine.
