the squealing noise is most likely a loose drive belt , the drum is powered by a large belt to a motor , the belt and idler pulley are most likeslyin need of replacement

The drum rides on two rubber rollers with nylon or plastic centers which become worn over time. You can access the rollers by removing the front lower cabinet under the door. Other points to check are the tension pulley which provides tension on the belt which you can access from the removed lower panel. The cabinet has a felt ring as a spacer preventing the drum from rubbing against the cabinet which may have fallen or become worn, which is rare. If you still have not found the cause you can attempt to run the motor without the belt to eliminate squeaking from the motor.

From back of dryer remove access door to disconnect belt from motor & tensioner.(remember how belt was placed on tensioner & motor pulley) You must remove dryer front panel ( look for 2 screws at bottom of front panel) Pull out from botton of front panel to remove, exposing drum end retainer brackets, remove brackets, allowing access to drum. Slide old belt off & new one on.

Hi,

Thank you for contacting Fixya.com.

Pull your dryer out from the wall. Behind it, on the bottom, you will find a lower panel that will give you access to the unit's belt tensioner (also known as an idler pulley arm). Remove the screws holding this panel in place, and then remove the panel itself. Reach inside and release the belt tension by removing the belt from the motor pinion.

The belt tensioner pulleys bearing is dried up squealing while turning. My advice is to replace the belt & the pulley on the tensioner
The top and front panel will have to be removed to access these parts

The squealing noise is from the belt tensioner. Replace the pulley only on the tensioner along with a new belt. The bearing in the pulley is causing the squeal. Sears will sell this in a kit. The top and the front panel of the dryer will have to be removed to replace these parts

replace the belt and tensioner pully to eliminate the squealing

Sears sell these parts in sets

A loud squeek is normally caused by the tension pully or the rear drum rollers seizing. Remove the two screws holding the inspection panel between the washer and the dryer. Remove the panel. Slide a 1/2 inch paint scraper between the top and the cabnet front and releave the spring loaded clips that hold the top on and remove the top. Loosen the two screws at the bottom of the dryer front panel. Looking down inside the front panel remove the two screws holding the front panel to the cabnet. Mark and remove the wires going to the door switch and remove the front panel. At the rear of the dryer remove the inspection plate at the bottom of the dryer and remove the belt from the spring loaded tension pulley. Go the the front of the dryer and remove the dryer drum and belt. Now you can check to see if the rollers are worn or seized and check to see if the tension pulley is seized.
Purches a kit that includes a new belt, drum rollers and tension pulley and replace all. Reassemble the dryer in the reverse as to how you took it apart.

Here's how to replace a belt on an GE Profile DPSE810EG4 electric dryer. There may be some minor variation for other electric GE dryers, but it shouldn't be too different. DO NOT USE THESE INSTRUCTIONS ON GAS DRYERS AS ADDITIONAL PRECAUTIONS MAY BE REQUIRED! For the electric DPSE810EG4, you will need a #2 Philips screwdriver, a flashlight, a new belt, and patience. You will also need something very close to the left front of the dryer against which you will lean the front panel. A chair, a washing machine, or a wall all work fine for this purpose.

1) UNPLUG THE DRYER FOR YOUR SAFETY.
2) Pull the dryer away from the wall and disconnect the ducting.
3) Remove the top four screws on the back panel. (These secure the control panel)
4) Open the dryer door and remove the two screws on the top of the door frame. (These secure the top panel.)
5) Pop up the front of the top panel and slide the top panel forward an inch.
6) Unlock control panel by sliding it to the right, then pull it up to detach it from the top panel.
7) Lift off the top panel and set it somewhere
8) Undo the two screws that hold the front panel.
9) Pull up a little on the front lip of the drum while hinging the front panel forwards. On the DPSE810EG4, you can set the drum down on the support member that is underneath it. (On other models you might need to put something under the drum for it to rest on.)
10) Lift the front panel off of the pins that secure its lower end, and then hinge it to the left (be careful not to yank the wires). Lean it up against something.
11) Open the access door on the back. (On the DPSE810EG4 the access door is the exaust duct itself; remove the screw that secures it and slide it out of the dryer.) Set your flashlight inside the dryer aimed so that you can see the motor and the tension pully.
12) Remove the old belt. If it's snapped in half you can just pull it out. Otherwise, reach in through the back access door with your left arm and pull it off the motor, then come around front, lift up the front of the drum a little and slide the belt off the drum.
13) Reach in through the back access door with a cloth and remove any grease blobs on back of the tension pulley axle. (This way you won't accidentally get grease on the belt during the difficult step which comes next!)
13) Install the new belt. Lift up the front of the drum a little and slide the new belt onto it (the side with the parallel grooves should be touching the drum). Reach into the back access door with your left arm. Grab the belt and pull it around the right side of the plastic tension pulley and then pull it down around the metal motor pulley. You're less likely to get your fingers stuck if you grasp the belt from the front. (The side of the belt without the parallel groves should be in contact with the tension pulley. The side of the belt with the parallel grooves should be in contact with the motor pulley.)
14) Replace the front panel. Set it down on the pins, then hinge it forward while pulling up on the front lip of the drum. Secure the two screws.
15) Make sure the drum turns OK. (If it's fairly difficult to turn, you may wish to try removing the front panel and then try putting it back so that the drum sits inside the felt strip semicircle rather than compressing it. A drum that doesn't turn well will stress the motor and cause it to pause mid-cycle.)
16) Replace the top panel. Put it on top of the dryer, insert the control panel tabs into it, and lock them by sliding the control panel to the left. Slide the top panel back and pop it down in the front. Secure the front with the two long screws and secure the control panel with the four short screws.
17) Replace the rear access door / exhaust duct. Double check that you didn't leave anything inside (including your flashlight). Slide the exhaust duct back into the dryer and secure the screw that holds it.
18) Re-attach the rest of the ducting and move the dryer back into position.
19) Plug it in and make sure it works.

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)
