first I took the dryer apart 1st thing i did was unplug the power supply (safety first) then I removed the top of the unit then removed the front cleaned all the lint from the inside of the cabinet I found the proper belt size on part select.com the next day I had my dryer belt delivered (which cost 1/3 the price of the local repair shop price)
then I placed the belt over the dryer drum and made sure it was in the general location it should be I then replaced the front cover and the top. then I removed the rear cover which was held on by six 5/16 sheet metal screws which gave me access to the drive pulley and belt tensioner the belt goes on by going under the tensioner then around the drive pulley
Then i rotated the drum by hand to make sure everything had clearance I then buttend everything up plugged it and started it up it workd fine and I figure Ill get another 8 years out of it

Heater element went out

  • Customer: Brian from Clinton MO
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers
  • 87 of 105 people found this instruction helpful
First of all, unplug the dryer. I removed the two screws on the front of the cabinet to remove the top. I then took out the screws to remove the dial panel. Release the belt for the drum through the access hole in the rear of the dryer. Remove the front cover and pull the drum assembly out.

Remove the element disc from the rear of the housing, take note of the the wireing placement. Replace disc and reverse order of disassembly.

This job was easy for me as I am a tinkerer by nature. The hardest part of the whole job was waiting on the part, which by the way was ordered on a Sunday evening and I had the replacement in my hands and back in the dryer running by 1:00 PM on the following Tuesday!

I book marked this website and WILL refer it to others who simply need a repair, not a costly new appliance!

dryer wasn't getting hot

  • Customer: edward from Sunnyvale CA
  • Difficulty: A Bit Difficult
  • Time to Complete: 1- 2 hours
  • Tools Required: Screw drivers
  • 17 of 23 people found this instruction helpful
1. removed two screws to take off top.
2. removed two screws to take off front.
3. Took belt off pulley and removed drum.
4. inspected old heating element at back of dryer - saw broken wire
5. replaced heating element (round w/ heating coil)
6. Re-assembled dryer

Helpful hints:
1. mark down or take pictures of all wires before removal - easy to mix them up
2. when you re-attach drum-belt, it should be taught. Comes straight down wall around metal pulley and then forms an "S" as it wraps around plastic pulley on way up. To re-attach, stick both arms into dryer - one to pull plastic-pulley and other to attach belt.

First I removed the removed the screws that held the top on the dryer. Next I removed the screws that held the controls on from the back. I then removed screws that held the left side in place and removed the drum by first removing the drive belt.
The heating element unit was removed by removing four screws and the wiring harnes. I reversed the procedure to install the heating unit and put the machine back together.

worn out drum bearing(squeaky)

  • Customer: Warren from Ballston Lake NY
  • Difficulty: A Bit Difficult
  • Time to Complete: 30 - 60 mins
  • Tools Required: Screw drivers

If you're dis-assembling the dryer panels to remove the drum to acess the bearing located at the rear of the drum,don't hesitate to buy a idler pulley kit and a belt.It's easier to change them now,while it's apart. besides,their all pretty much in the same state of wear! In lew of prying my son away from the computer,an extra set of hands is a help, I used a scrap piece of 4x4 with a 1 inch whole bored in one side to place the bearing end into to steady it to get the screws started. otherwise you need to have 6ft.arms! re-assembly wasn't bad, a magnetic tipped #3 screw driver eliminates the frustration of dropping panel screws down inside the partially assembled body.

Drive Belt Replacement needs Drum Modification

  • Customer: John from Windham NH
  • Difficulty: A Bit Difficult

To perform this repair (please see numerous descriptions on the web for generic belt replacement) I had to rivet two loose parts to the drum in order to reinstall the drum. Specifically, the loose metal disk and hot air shroud at the rear of the drum (near the rear berrings) made it impossible to realign the parts to reinstall the three torx bolts at the rear of the drum during reassembly. These two loose parts are positioned behind the drum (when looking inside the drum) i.e. between the drum and the rear berrings.

It was necessary to align the mounting holes in the drum, disk, and air shroud outside of the dryer itself and then to rivet them in place (making sure the smooth rivet head was INSIDE the drum as to avoid providing a rough edge where the clothes could catch during tumbling). Just press the 3 torx bolts through the holes to establish correct alignment. Be sure to install the rivets ouside of the contact area between the heat shroud and mounting plate. You should see an indented pattern on the heat shroud that you can use as a guide.

It was also helpful to make a black mark on one of the drum mounting holes (inside the drum) and its mate on the berring attachment plate - to help orient you when installing the drum with the 3 torx bolts. It only aligns one way - and making the marks will save you aggravation while your head is in the drum during reassembly. Loud swearing at this point only punishes your ears because, after all, your head is in an acoustically punishing echo chamber - and the echoes make it seem as if the dryer is actually cussing YOU and your incompetence out...

I hope this helps someone else save some time in reinstalling the drum.

One additional pointer: you must remove the lower plate on the rear side of the dryer to wrap the belt around the tensioner pulley and motor drive. The belt wraps, from right to left, first around the motor pulley and then up and to the left around the tensioner pulley. Just place the belt around the motor pulley, and then pull the tensioner pulley toward you and leftward until it clears the belt, then push toward the front of the dryer - and let the tensioner contact the belt on the right side of the tensioner pulley.

And finally, the ribbed side of the belt makes contact with the drum and the motor pulley. The smooth side of the belt is in contact with the tensioner pulley. Good luck, and may the choice words I used during the process be unnecessary for you... for you... for you!

Squeaking Dryer - Rear Drum bearing gone bad

  • Customer: Jason from Cary NC
  • Difficulty: A Bit Difficult
  • Time to Complete: More than 2 hours
  • Tools Required: Screw drivers, Socket set
  • 11 of 14 people found this instruction helpful
First, I loosened the the top control panel and then loosened the top flat roof panel which allowed me access to the inside of the dryer. Then, I removed the front panel which allowed access to the drum. I was amazed at the amount of lint that was inside the dryer itself. Most of my time was spent in the disassembly and cleaning of the internal cavity around the drum. I reached below the drum and removed the belt from the pulley wheels and then unscrewed the drum (from the inside) from the back of the dryer and bearing kit. I removed the diffuser and cleaned it thoroughly. Then I replaced the entire drum bearing kit - the old one was almost completely dissentigrated. I probably should have applied some kind of non-flammable lubricant to the new bearing kit - the instructions did not include this step but after about 3 loads a slight squeak (different). I put everything back together - applying the new drum kit will require 2 sets of hands (my 9-year old daughter did great at this). I re-assembled the dryer and it works great, again except for the slight squeak that's still there. I may disassemble it again and apply some lubricant but I do not know what kind to get; I need to check that out.

Dryer would not start

The end repair was very simple and took minimal effort. The time and difficulty was all in the testing. I disassembled the dryer and removed the drum and then hard wired each thermo-fuse to determine where the fault was. After test all of those I was stumped. When I opened the door the light would not come on so I assumed it was a power fault closer to the source. However after all of my testing I couldn't find anything wrong. I then removed the light bulb and realized it was burned out which led me to the door switch being the fault. I removed the switch and soldered the three wire together and the dryer started right up! All I had to do was order a new $15 part, unsolder the wires and plug them in. Would have been so much simpler if that light bulb hadn't of been burned out causing me to over think my diagnosis. This was my first major appliance repair and I did it with only the help of the parts diagram provided on the website.

Everything is cleaned as it is removed.

Remove the two screws holding the top down.
Disconnect two wires from door switch.
Remove the two hex screws holding the front on.
Remove the 4 screws holding the access panel on the back and disengage idler pulley to loosen the belt.
Remove the drum.
Label the wires then remove the heating element.
Check orientation of ground strap before disassembling rear bearing.
Remove four screws holding rear bearing to back of heating element.
Install rear bearing and ground strap on to heating element.
Reinstall heating element.
Reconnect wires.

Most Important : Get help putting parts back on drum! I didn't and that's why it took over 2 hours.
I will describe how I did it.

Unscrew bearing from inside of drum.
Wrap screwdriver with tape to a little larger than the screw hole.
Use small screwdriver to line up the drum, shim and deflector.
Don't forget the brass shim. It wasn't on the parts diagram.
Start two screws don't tighten them yet.
Remove Screwdriver and start third screw. Tighten all three down.
Put belt on drum.
Install drum and belt.
Reverse disassembly.
When putting the front on make sure drum rests in the felt.

I rated this a bit difficult because I did it myself. With help this is a fairly easy repair.
