Furnace squeaks when it turns off
Edit:
So... I thought the system would let me know when people replied to my post... so I came back to see if I could bump this and WOW, everyone here has given me a ton of leads and advice... Thank you so much to everyone who replied!! ************************************************** ******************** Hi, First time poster... I'm fairly new to the US forced air furnace system, but my question is something that I haven't gotten an answer to on google... so here I am. My furnace appears to be functioning normally, no strange sound except when it finishes and the thermostat clicks off... when the airflow stops there is a horrid squeak, followed by another squeak and then a third... this has been happening for quite sometime, with this being the third winter in the house in the north east but to my ear it is getting longer. If this is normal and is just the sound of a vent closing, that would be awesome but I'd like to check! also the thermostat clicks off and the furnace takes a minute to shut off... it is a high efficiency furnace installed in 02. Much appreciation to anyone out there who has a clue to what this could be. Thanks, Mark. Last edited by Mark P Williams : January 9th 13 at 12:37 AM |

BUT if the flappers are being blown open by the furnace, you've got a lot of wasted heat that needs to be tracked down and fixed...like a leak in the suction side of the furnace. |

Much appreciation to anyone out there who has a clue to what this could be. Thanks, Mark. The easy answer is for question 2: the reason the furnace takes a minute to turn off is to allow the fan to remove the remaining heat from the heat exchanger both so that it isn't wasted and so that the heat exchanger cools down more evenly. That helps the heat exchanger last longer. As far as the squeak, have you tried having someone turn the fan on and then off as you listen to first the blower itself, then some of the ductwork/vents to see if you can isolate the noise? It sounds to me like the blower may need some lubrication, but that's hard to tell from where I'm sitting. There should be a switch on the thermostat that says Auto and On. Switching it to On should turn the fan on even if the thermostat isn't calling for heat. You can use that to turn the fan On and Off by setting thermostat to a low temperature. Since the furnace won't call for heat, Auto will be the same as Off and On will be, well, On. You should be able to isolate it if it happens every time the blower turns off. By the way...No, it's not "normal". |

The shut-down delay is normal - the fan stays running untill the heat exchanger sheds the majority of it's heat. I suspect you have a direct drive fan, judging by the age. I'd be suspicious you MAY have a bearing or bushing problem. Should not be hard to determine with a bit of sleuthing. Much appreciation to anyone out there who has a clue to what this could be.

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. |

Personally, I wouldn't lubricate anything until I found out what was squeeking.
The way you pinpoint the source of noises in machinery is with an inexpensive tool (typically $15 to $20) called a "mechanic's stethoscope" which you can buy at any place that specializes in automotive mechanic's tools: You simply touch the metal probe of the stethoscope against any part you suspect of making noise, and the closer the probe is touched to the source of the noise, the louder the noise will be heard through the earphones. In this way, you can quickly and easily pinpoint the source of noises in all kinds of machinery, and that includes finding out where that squeek is coming from in your furnace. I have a $15 Lisle mechanic's stethoscope that I've been using for over 20 years to find the sources of noises in the machinery in my apartment block, like the washing machines and clothes dryers. For a cheap tool, it works surprisingly well. |

On my unit, I have a zone controller, now with 3 zones. With the everything off, all 3 zone dampers are wide open. When 1 zone calls, the other 2 will close. At the end of the cycle, those 2 zone dampers will again open. They are electrically held open and when 24 volts is removed, the damper closes via some type of spring return. |

Here is what should be the sequence of events; 1. thermostat shuts off;- you might hear a click [from the thermostat] 2. burner finishes cycle- when it stops you should just hear the pump and 'fire' stop. 3. The fan will continue to run until the plenum reaches a pre-set temp. When the fan stops, if all is well, you'll hear nothing. if the fan stops with a squeak, then you might have a belt driven fan that needs tightening/replacing. Jim |

Jim 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. |

I've noted more fan belt squeak on start up.

On start-up, the motor/fan goes thru that speed range very quickly, so no squeek. On shut-down, the fan/motor coasts down relatively slowly, spending more time in the speed range where there is a squeek. So you hear it only on shut-down, not on start-up. I agree to not oiling until noise is located, but oiling once a year is a very good practice to save bearings and $$$. |

If this is normal and is just the sound of a vent closing, that would be awesome but I'd like to check! Not normal. Also not rocket science to run over to the furnace, stand there and LISTEN to see if you can narrow down the source of the sound. You should also consider calling a professional. An experienced reputable professional has certainly seen this exact problem before and should have a pretty good idea what the problem probably is without even hearing the noise or looking at the unit. All he'll need to know is the model of the unit and the circumstances under which the noise happens. |

Jim On my old belt drive 2 speed furnace fan the belt chirped every time the fan swirched from high (heat or cool) to low (standby circulation) and not when starting. The inertia of the spinning fan was higher than the accereation torque of the motor. Switching to low was like slamming the brakes. |

That brings back some memories. It was maybe 1991, and night time. The
blower on my furnace started to really totally squeal. I pulled a couple bolts, and the blower housing came out. Found a couple of oil holes on the motor. Dripped on some 10w30 which was what I had. Formed a bit of an air lock, so I poked around in the bubble with a bent out paper clip. After a while, it took some oil, and the fan worked a lot quieter.

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. |

Furnace squeaks when it turns off
And then, someone gave me Derby's furnace with the door!
Hey, I'll give it back, OK? Christopher A. Young Learn more about Jesus www.lds.org .. "John Smith" wrote in message eb.com... From: "DerbyDad03" Newsgroups: alt.home.repair Sent: Monday, January 07, 2013 3:45 PM Subject: Furnace squeaks when it turns off My Perfection had a large door (maybe 2' x 3.5', it's been a while) with a handle that gave you easy access to the blower assembly. It was behind this door that you had access to the filter, blower motor with it's oil inlets, the squirrel cage, the belt, etc. Everything blower related was behind that door and readily accessible. Agreed! Those were the good ol' days. Then some unsupervised 5-year-old turned the handle, opened the access door, stuck is finger in and was injured. His mother called the local product liability attorney and the rest his history. |

I have totally no confidence that any lubrication is
permanant. Yeah, oilite bronze bearings, and all. But, I don't believe it. Christopher A. Young Learn more about Jesus www.lds.org .. wrote in message ... The "old iron" needed regular oiling, but the OIP said new in 2002 - MOST had gone to direct drive permanently lubricated by that timeframe. |

I have long believed that you are exceptional.
My gut sense, through the usenet group, is that you have a wide variety of skills. Christopher A. Young Learn more about Jesus www.lds.org .. wrote in message ... On my 7 year old ? "modern" furnace I can still get at everything quite easily. Lnowing what to do with it might be a different story!! I DID manage to fix the shirp/squeal fron the inductor fan. The web was loose in the cub - I brazed it up over 5 years ago (dealers had no new parts in stock - part was covered by warrantee but not labour) |

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 ..

"permanently lubed" really means "lubed for life" - as in, when the lub runs out, it's done. Some stuff cannot be lubed without total dissassembly. Some things you can puncture and oil - and some things just totally go heck in a handbasket if you get the wrong kind of oil in trying to do right. |

That's what the old Onan single lunger out in the garage is for. If the power is out long enough to get dangerously cold inside, I go out and connect the Onan and start pulling on the (non recoil) rope starter. I'll get warmed up, even if the genny doesn't start and I don't get the furnace running... The thing is definitely old enough to vote - I doubt it's older than be, but it could be pretty close. 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. |

Lubed for life, backwards, means it dies when
the lube runs out. I've had to drill, and pump some oil in. At least once, in the last few weeks. Christopher A. Young Learn more about Jesus www.lds.org .. wrote in message ...
