Furnace squeaks when it turns off
We should start a thread on "made it work, with what we got on hand". One of
my favs, was when a motorist's auto accelerator cable shield frazzled. Gas pedal flat on the floor. I had some nylon line, so I rigged it around and over. Pull the cord to accelerate. I hope he go thome OK. Christopher A. Young Learn more about Jesus www.lds.org .. wrote in message ...

I've got a disconnect in the garage that lets me tap into the furnace circuit in the winter and the freezer/fridge i n the summer. |

Best one I saw was a newfoundlander with a '55 Pontiac came into the shop and wanted to borrow a few wrenches. The old six was knocking to beat the band. He dropped the pan, disconnected the blown con-rod and jammed the piston up to the top of the cyl with a piece of 2X4, then cut odd a few inches of his belt and clamped it onto the crank with a hose-clamp. He buttoned it up and returned my wrenches, then headed back to Nfld from Elmira Ontario. |

wrote: Yow, life imitates fiction. In my book "Custodian Plus" I wrote of the gas valve on the steam boiler, and how the custodian was able to "throw the lever" and open the gas valve, during the power cut. Thanks, glad to know it's not totally fiction. I've heard that 12 vdc will open some "modern" gas valves. 24 VDC (two car batteries in series) might work instead of 24 VAC. Don't know. Christopher A. Young Learn more about Jesus www.lds.org . "DerbyDad03" wrote in message ... The instructions included a section on how to heat the house during a power failure. You could manually open the main gas valve and push in a tab that would hold the valve open. No power meant no blower and no high temperature cutoff. The instructions said to use a 10 minute on - 30 minute off duty cycle, but it was completely manual. Fall asleep and it would stay on for hours. I assume bad things could happen, especially to the heat exchanger with no blower to remove the heat. When the gas valve went bad, they had to replace it with a modern one that no longer had that "feature". The next winter we had an ice storm and I was without power (and my furnace) for 4 days. I heard that Mormons squeak while having sex !!!! |

I had an old lawn mower with a rope start, no recoil. I finally made a rig
for my electric drill, so I could spin the flywheel via the nut, and get it going that way. Doesn't apply to generator, used when the power is out. Christopher A.

I did it once - on the Onan - and when it started it took the flywheel nut/bolt right off.

It sounds to me like the blower may need some lubrication, but that's hard to tell from where I'm sitting. The blower should be lubricated on all furnaces at least on a year. It dont sound like you have done this. Just begin by lubricating the blower and the blower motor. *Normally 3 to 6 drops of a light oil in each bearing. *(Some modern motors do not have oil holes. *They are supposed to be lubricated for life). *If the blower has a V-belt (fan belt), that could squeak too. Lube it, then watch the blower while someone shuts off the furnace. Blowers in all the furnaces I've had anything to do with have had permanently lubed bearings for many decades now. In fact every residential type motor, fan, etc that I've seen for a very long time doesn't require periodic lubrication. Also the design of the high efficiency furnaces may not even allow for access to the bearings for lubrication. Not saying that IF the squeak is actually coming from the bearing, THEN it would be appropriate to lube it. Just that everyone shouldn't be worried that they need to regularly lube bearings that have no provision for lubing. |

DerbyDad03 wrote: -snip- Wouldn't the fan belt squeak on startup, not shut down? I'm thinking of the squeal that a loose automobile fan belt makes as a car accelerates. It doesn't squeal once you reach a steady state speed or when you take your foot off the gas because it's not going to slip as it slows down. Wouldn't the same thing occur in a furnace - slippage on startup but no more torque (?) once the motor shuts down, therefore no squeal. You might be right. * It has been a long time since I had that squeak. Jim The furnace is a high efficiency unit that is ten years old. That says to me that there is no belt. Has anyone seen such a furnace with a belt drive? Every one I've seen has been direct drive. |

I have a similar problem. When the furnace shuts off, I've been getting a squeak. I took the access cover off, and don't get the squeak when the cover is off. When I put the cover back on, it squeaks.
I'm thinking I may not be getting adequate combustion air and there's a sudden change in air pressure in the furnace when the burners/fan turn off. I tried putting some silicone spray lube on the rubber gaskets on the access panel, but that hasn't solved it. I'm not sure how to go about checking the combustion air supply. Thanks. |

First question is what do you mean by the "furnace shutting off"? If it's when the burner stops, then it could be something to do with the combustion air supply, which presumably is via fan. Or is it when the air handler blower stops, in which case it's not combustion related? If it's the latter, could be some duct work at the furnace flexing as the air pressure stops. |

It happens when the burner shuts off. Its like a pressure differential or something. The exhaust blower fan keeps going. I checked the combustion air inlet. Cant find anything.
