Granny’s Gurgling Furnace

A rare phenom occurred over the weekend here in the swamp. It got cold as hell. I turned on granny’s Amana high efficiency furnace and all I heard was a gurgling sound. Not good. The same thang as last years fiasco. First time it gits cold the dang heater acts up. The draft inducer motor full of water, the furnace all rusted to hell, the electronics all wet. Dayum. So I removed the blower and dryed it out with a hair dryer. Dryed all the electronics and the furnace. I figured Mobile is the wettest city on the planet besides Seattle so I went up on the roof. Found no leaks, Hosed it down with a water hose while I had peeps up in the attic looking for where the water was coming from. Could not find one damn leak. So I got to looking at the ac drain. I poured some water down the drain and BOOM there it was. Stopped up ac drain. To make matters worse the leak was never seen because the water was going through the wood sub-flooring under the furnace. I had to blow out the tube going into the draft inducer and open it up, (full of mud), I had to take a tooth brush and clean the orifice on one of the burners, naturally it was the one with the flame sensor fartherest away from the gas valve. I didn’t have to clean the flame sensor itself which was amazing to me. I also replaced the screws on the blower with new stainless ones. Never know when I might need to remove it again and those rusted ones were hell to get out. So if you hear a gurgle in your heater shut er down and dry er out.
Right now it is about 80 degrees in here(73 outside) Grannys got it hot as 3 yards of you know where. So much for the cold weather. LOL
