Question about Whirlpool LER4634J Electric Dryer

1 Answer

The small belt in the middle of the drum broke. After I pulled the drum off I noticed a small plastic wheel on a metal bracket loose in the bottom of the dryer. I can not see where this reataches and I didn't see a screw in the dryer to reattach it.

Its called an idler arm, it attaches next to the motor as this is what keeps tension on the belt so it will stay tight on the drum. If I remember correctly there is a slot on the bottom of the dryer close or right next/past the motor, slide it into that slot, with the small plastic wheel up next to/by the motor. I am attaching a diagram for the belt it will help. Good Luck and I hope I helped Tim:

Remember the belt should ride in the middle of the drum and the back of the drum is lipped and should go behind the drum rollers. Once the belt is thread it will be tight and the idler arm will not longer be loose.

When peddeling ec3000 cateye ergociser bike it has good tension but after a few revolutions it lets go and free wheels.

Sounds like the belt is loose on the pulleys? Maybe something else, but you have to get inside it to check.

* Refer to the service manual (the EC3200 is almost the same as a EC3000) for hints :Page 4,5,19,20. Read this manual.
* Take out every screw holding the white plastic cover and the crank bottom bracket cover. Also take off the screws that hold the black seat post and handle bar post covers together. Now the covers should come apart to access the guts.
* Inside there is a belt system and chain system.
* Belt system: Check there are no loose nuts on the axles that connect to the pulleys. If there are, try to pull the pulley so that belt is tensioned as you tighten the nut.
* If the plastic teeth are loose on the big belt pulley (that's bad), you may have to try to glue it back to the metal part of the pulley. Don't be sloppy and get glue on the teeth... A runny epoxy may be able to get into the interface between the plastic teeth and metal part.
* If the belt is worn out you may be able to find it with a WWW search or from an industrial supplier like
McMaster Carr
* Chain system: Check the chain freewheel (the small one) is working correctly.

My dryer belt broke and it looks like one the wheels broke but i looked the part up on line and looks like the wheel comes with the kit i just want to know is this how it is suppose to look like it comes...

that one wheel in question is the "belt-tensioner" wheel or known as the "idler-pulley" that keeps the belt tight that turns the drum,it has a bracket and spring that hooks to the base of the machine.which is what puts pressure on the belt

I am wanting to replace a drum bearing, and I've gotten the dryer top panel and front panel off, but I don't see how to release the drum belt (which is okay) so I can get the drum out. How to do...

On the bottom left side next to the motor you will see a small plastic wheel (idler pulley) which the belt is wrapped around. The wheel is attached to a L-shaped piece of metal which is known as an idler spring arm which is made out of spring steel.

Move the arm one way or the other and you will notice the belt tension getting looser. Push the arm further that way until you can get the belt off the pulley an motor. Use caution as the spring arm has torque on it and could snap back.

Once the belt is off the motor and idler pulley you can then pull the drum out. You will need to lift the drum up slightly since the back sits on drum wheels(the groove on the back of the drum). Take the drum and belt out together.

Once you have made the repairs, install the drum in reverse order.

Note: Before removing the belt, make a diagram of how the belt goes around the motor and pulley for future reference.

Hope this helps you out.

Have you tried turning the drum with belt removed to see if sound is from drum or motor.If you cant get at belt easy thru. top ( make sure power is off) then you will have to split the casing which will give you a great view of all the moving parts to see if any loose parts.It may be that the bearings have gone so badly that it is clunking as it turns.Normal bearing failure noise is a rumbling.
Remove 2 screws at rear underside of top lid and remove.On top middle either side by springs remove the 4 screws holding back panel,down below at rear there is normally 2 or 3 screws on corners of panel,now go to side of panel bottom middle by seam and remove round white plastic covers put small screwdriver in hole and pull out there is a screw behind each (8mm small socket).Now by water inlet valves prise out white plastic housing with valves still inside now put screw driver in spli on side panel either side and work it back you will have to hold down drain hose to clear panel,once off you can inspect for any damage or loose parts,check drum pulley is not loose or worn,check motor also concrete balance weights one on back top of drum casing and one at front around door seal,sometimes these come loose.To refit casing it is a reverse of removal.
Hopefully this will be helpful.

Good Luck.

Loud squealing sound when the basket first spins up this is a Kenmore stacked set, washer on the bottom, and dryer on top

Your problem could be a bad bearing...The drum rides in a bearing at the rear middle of unit..Its basically a plastic insert...When the dryer is first started the bearing will squeal until the plastic warms up..Normally you will hear the squeal at the back middle of dryer...Your problem may also be the belt tensioner...Again a plastic wheel with a metal bearing inside...Normally this squeal will be from start to finish..

Intermittent Squeaking

You know how when the pads on your car get worn they start that noise? Well the bearing that holds the tub has a metal bracket. When that plastic wears down it begins to makes those noises. If left alone the metal bracket will eventually cuut into that drum bearing like a guillotine. I have pictures. Have the women and small babys leave the room: Click (HERE)

Belt Broke and pulley bracket came loose, where does pully belong

It goes into the front of the motor on the floor with the wheel to the left. You insert the belt between the idler bracket and loop it over the motor pulley.
The ribs of the belt need to be up against the drum for grip. It is best to have a person hold the drum while you do the pulley. Here is a page that shows various belt routings on different machines, yours is bottom right.
