Furnace running with thermostat off

Dec 29, 2008 27 Replies

Ok, found the control box and opened it up. It has blower control with a slider and a little knob and limit control box next to it. I taped on both a bit and moved the slider around. Now the heat will turn off when it reaches temperature, but the blower will run forever ever after it has cooled down. I have it set to auto. Could it be faulty blower control? Thanks

He went to the rooftop and sacrificed his life to fix it. The Mormon died about 2 years ago.

I recall but I don't know that we ever learned whether the problem was fixed or not...

I moved the fan switch from "on" to "auto"

What kind of thermostat? Battery type? Batteries fresh? Take the batteries out and see if it continues. If it doesn't put the batteries back in. If it still persists, time for a new thermostat. I recommend Honeywell VisionPro series.
