Richard checks for holes in the exhaust flue that could leak carbon monoxide, particularly where the pipe meets the furnace. Small holes can be patched with foil tape, but corroded flues must be replaced. He also adjusts the flue pipe's barometric damper, which moderates the chimney draw. "A big, tall chimney in an old house tends to suck too much air, compromising efficiency," he says. "Your service pro can weight the damper to lessen the draw.
If your furnace’s motor runs but the blower doesn’t move air, the belt that connects the two probably has broken. Replacing it is an easy fix. First, turn off all power to the unit and turn off the gas at the gas valve that serves the furnace. Remove the door on the front of the furnace cabinet to give you access to the blower (it might be on a slide-out drawer.) Check the number stamped on the belt and get an exact replacement from a home center or heating supply outlet.
Customer stated their blower fan is consistently running. She has had the furnace off all summer and just fired it up and it will just blow consistently. Upon investigation, the technician found that the damper control was sending 24V to G terminal while switched off. This indicates a stuck closed relay. I disconnected it and tested the unit. Due to age of unit, I would recommend upgrading to a more efficient model.
