Can't stop the sqeek

[JJ]

Hello

I have been working on trying to fix a noise coming from this dryer.

It starts about 10-15 min into use.  It is a humming/vibration noise that progressively gets louder.  Sometimes it goes away for a min then starts again.  Sometimes there is a bit of a rattle.

So far, I have eliminated the usual suspects.   I removed the tub and the belt.   I ran the motor without the anything attached to it.  Sure enough 10 min and the noise starts.   I cleaned out the blower, the fan and all the ducting.  The blower looks in good shape.  no breaks or cracks that I could see.

The motor shaft seems tight and spins easily.  There is no play.
the rubber dealy holding the shaft in place looks in good shape.  

It seems to work ok, but not being able to find and fix this noise is driving me nuts.  

Any ideas?

Did you remove the blower? Sometimes things get behind there.

Did the drum support ball have any wear on it?
Also double check the tension roller for the belt. The inside bushing on the tension roller will wear and cause a delayed squeak sound.

Hi

No, the ball was good.  I had replaced that only a few months ago.

I removed the drum, the belt and the tension roller. The only thing attached is the blower.   The noise is still there.  I cant tell if it is coming from the belt end or the blower end of the motor though.

There is a plastic/rubber round gasket piece that has the little metal spring clamp on it.   Does this wear out?   Does this come with a new motor is is that a separate part.
If I replace the motor, do i need to replace the blower as well?

It will probably cost as much in parts to fix this as buying a new dryer, but I can't let this beat me.

Where is this piece?

It is around the motor shaft on the belt end.  I dont know what to call it , but it is the round plastic rubber thing around the shaft that holds the motor in place. it has the metal spring clamp that holds it down to the bottom of the dryer.
This is a fridigeair frontload stackable dryer.

Also check the front drum felt glide. If it is worn a button or zipper could be lodged in there and it could be hard to see. I have seen quite a few. If you opened up your dryer and there was a bunch of buttons in the bottom of the dryer it is a sign it needs replaced .

You might want to look at the blower again.   More than once,  I have had to replace blower housing and wheel.    On the outer blower ring,   if it has a hairline crack,   it will make noise as the blade heats up.    When it cools down,  it is fine.  It is common on the frigidare built GE dryers.

Rollers.

No rollers on this Frigi Matt, just a tensioner with a pulley.

Remove the blower wheel and run the motor.

That squeal could be the main bearing in the rear is cutting into the bracket. After a long time the whole thing will be cut in 2.

He said he removed the belt and ran just the motor and got the squeak.
That is why I suspect a bad blower wheel rubbing on the back side of the blower vent.

OK then you are getting that dry bearing growl that occurs when the bearing gets hot. You could use some HVAC oil (zoomspout) and drill an 8th inch hole over each bearing well (without hitting the shaft). Manufacturers wrap rotten cotton around the sleeve bearings on either end of the motor and add oil to lube the oillite bearings. If you looked at a sleeve bearing under a microscope it has 10,000 tiny holes. The oil seeps into the sleeve bearing and forms a film between the shaft and the bearing. Unfortunately they seal the bearings. Heat from the dryer and time causes the oil in the cotton wells to dry up. Adding some heat resistant non-dissipating non-flammable zoomoil will stop that bearing growl.
