Hi a yr ago I woke to my blower running non stop.. even if I shut off furnace with thermostat... I shut off furnace switch on the furnace in basement and turned back on.. I opened up thermostat everything looks fine.. its blowing hot air just won't shut off.. at that time I called my furnace guy.. he turned on furnace checked it and of course... lol it was working fine blower shut off.. this am I woke to the furnace not shutting off again.? I have to shut it of manually at furnace switch in basement to get it to shut off any suggestions.. hate to call furnace guy again for it to start working on its own again and have to pay for a serv call etc.. Thanks D
