Question about Dryers
My dryer is making a loud squeaking sound when the drum turns. Does it need lubrication or a new belt?
Here we go. First unplug the unit. Remove the front panel by removing the 4 phillips screws just inside the door (on the hinges and just opposite). Next remove the greenish/ brown 5/16 screws that hold the front panel in. There are wires still connected (door switch and moisture sensor) but if you swing it to the side, you can leave them connected and still procede. Next, you have to reach underneath (very difficult to see this so you will have to do it by feel) There is a belt that wraps around the drum. On the underneath side of the drum as you follow the belt it wraps
around the motor pulley (small wheel) and the tensioner pulley (bigger wheel just to the right). Now with one hand, move the larger pulley towards the msaller one. This will give you slack and you can take the belt off both pulleys. Now pull the drum
forward. There you have the inner workings left. Now, there are 3 wheels. 2 black and 1 white. I would check the white one since you've already replaced the black ones. This is the pulley that provides tension when the motor is running (hence no noise when you take the belt off) I'm betting you'l find it does not turn freely (you should be able to spin it with your finger and have it coast to a stop insdead of stopping as soon as you take your finger off). You can get the replacement wheel from your local appliance parts store or on line from the manufatrues web site. However, if you do have to wait for the part, take the wheel off the shaft and wipe off the inside race of the wheel and the shaft for temporarily relife and useage.

Motor malfunctions usually call for service by a professional. There are three main causes of motor failure: lack of lubrication, a defective motor switch, or worn or frozen bearings. A humming sound can be related to a burned-out motor or a defective switch. Check these trouble spots before you call a professional service person or take the motor to a repair shop. Here's how to check a dryer motor:
Step 1: Remove the back access panel. Then reach behind the drum, motor pulley, and idler arm pulley. If these areas are clogged with dirt and lint, undue strain on the motor may be causing the humming noise. Worn or broken belts can also cause a humming noise. Check the belts for wear and damage. If the belts look all right, you may be able to stop the noise by spraying them with fan belt dressing, available at automotive and hardware stores and home centers.
Step 2: Turn the dryer on. The noise you hear may be the whirl of the spinning drum, not the motor. Some noise is normal.
Step 3: Force a little 20-weight nondetergent motor oil (not all-purpose oil) around the ends of the motor shaft. This lubrication may stop the humming noise. If this doesn't solve the problem, remove the motor and take it to a professional service person.The centrifugal switch on the dryer motor may be located on top of the motor. Humming, no motor power, and no heat can be caused by a faulty centrifugal switch. If the switch is externally mounted, check the terminals of the switch to make sure they are tight and not burned. If you spot trouble, remove the switch and take it to a professional service person for testing. A faulty switch will probably have to be replaced. Some centrifugal switches are located inside the motor housing; you won't be able to remove the switch in this case. Remove the entire motor and take it to a professional for repairs.
If the motor hums, but won't run the pulley on the end of the motor shaft, try turning the pulley by hand.Caution: Before turning the pulley, make sure the power to the dryer is turned off.

there are two possibilities for this question. 1) there is an idler roller that give the belt the correct tension . unplug dryer and remove idler roller see if it spins freely if not replace it @0 there are two drum rollers in back of machine thatdrum rides on remove drum it's self explanitory how to remove drum and very easy also. you can roll these wheels and check for free movement visually check them ,one or both should be worn out or the bearing in the wheel has failed before putting old or new wheels back sand the wheel shafts to get any gunk off them and that's about the only thing that can make a dryer squeek

This noise will normally come from a defective idler pulley. Access to the idler pulley varies by model, if your dryer has a lower front panel (kick plate) start there. It should lift up and off or it may be held in place with a few screws or snaps; it may also have a catch at the edges or center gap between the kick panel and main panel. To release the catch, push a putty knife, wrapped with masking tape, into the gap and push back the catch. The next easiest access point is the rear panel. The rear access panel is held in place with several screws along the outer edges. The last resort method of access is the removal of the entire front panel. The front panel supports the front of the drum and so removal is more difficult. Front panel removal varies. In general, access is gained by lifting the top (remove the lint trap screws first), removing the screws that secure the front panel, and detaching the panel from the drum.
When reaching into the dryer be careful of sharp edges on the cabinet and interior supports. Reach in to the belt and give it tug. It should be taught and have only a little give. The belt should go under the idler pulley and over the motor pulley. Lift the idler pulley toward the motor to relieve tension on the belt and remove it from the motor pulley.
Turn the idler pulley wheel, it should turn smoothly, quietly and without any wobble. Inspect it for cracks or uneven wear. If the idler pulley does not maintain proper tension or is damaged it should be replaced. Depending upon your model, the entire assembly or just the wheel or bearing may be replaced. Check the bearings as well for excessive clearance also(roller bearings)
