Intermittent squealing noise
I've replaced the rear plastic bearing on this dryer twice, so I am familiar with taking the unit apart. After replacing the bearing in December, the machine still made noise (which had been masked by how loud the bearing was). The belt didn't look so great and it's 13 years old, so I ordered one and a new idler pulley assembly.

First, I disconnected the power and pulled it out for access. Using a large blade screwdriver, popped the cover open from the two clips in front. Be sure to support the top cover when you open it on the tabs or they will bend - I propped it against the wall. I disconnected the two wires that go to the door switch, and then removed the two screws that hold the front panel and door in place and lifted/opened that and removed the front panel and set it aside.

Next, I removed the back access grill (2 screws) and popped the belt off the idler by relieving the tension on the belt. Using a 10mm socket, I removed the idler pivot bolt and idler arm assembly. I installed the new idler arm assembly in its place and reattached the spring.

Moving to the front of the dryer, I lifted the drum off the blower housing on which it was resting and took off the belt through the front of the dryer. I then replaced the belt in reverse. Back through the access panel on the rear, I put the new belt on the motor and idler.

Be sure to check that there are no flips in the belt. I rotate the drum by hand a couple of revolutions to be certain.

I then reinstalled the front cover and door, reconnected the door switch, replaced the access panel and put the cover back down, popping the clips into place.

Put the dryer back in place, reconnected the exhaust and plugged it in. Voila - quiet dryer.

As an aside, I also took the time to clean the lint out of the blower and exhaust with a vacuum cleaner hose.

Belt broke and the pulley broke.
I unplugged the dryer. Undid the top by taking out 2 screws and mounts on each side of the back. There were two screws in the front panel that had to be removed. One on each side. Then I took the two wires off the killer switch on the door. Marking which was top and which was bottom. Then I removed the front panel. Then I undid the drum which had 3 screws in. I took out the drum to find the problem. I replaced the drum putting the belt on. Then I took off the back panel at the bottom of the dryer to get at the idler arm. Took off the spring and unhooked the arm. I put the new arm on and replaced the spring. I then put the belt on to the pulley and closed up the back panel. I put back the front panel. I put the top back on. I plugged it back in and turned it on and it worked!

Dryer wasn't heating
Determined that the coil on the gas valve wasn't pulling in to ignite. Using an ohmmeter, I determined the coil was open. The coil was removed by pulling off the wire connecter and removing the two phillips screws holding the bracket over the two coils. The coil then slides out. I slid the new coil into place, replaced the bracket and two screws and reconnected the wire connector. It worked immediately. The actual repair only took 15 minutes. The bulk of the time was spent tracking down which part had failed.

Not enough heat
Checked PartSelect online for people with a. similar problem. Found most common problem was the coils.
I opened the top, removed the two screws holding the front panel, unclipped the wiring harness from the machine to the door and removed/cut the plastic wire tie and front came off easily. I put the front piece to the side after changing the light bulb. I cleaned out a large amount of lint and found the coils on the left hand side without trouble. Carefully disconnected the wiring clips, unscrewed the holding screw and removed the old coils. Installed the new colis, 1 has three prongs and the other has 2 so you ca'nt mix them up. Replaced the hold screw, re-connected the witing harness, installed a new wire tie, and re-stalled the two holding screws. Closed the cover and turned it on.
At first it did not heat up which was dissappointing; but then I left it alone and 15 minutes later it worked like new! And heated up just fine ever since.

Total cost about $35.00 with shipping. I took a chance that I would not need the sensor or the ignitor based on the comments of others and I just bought the coils. If I had to do it over I would have bought all three and saved on the shipping.

Brown stains on clothes.
Followed your website repair guides and the great belt replacement video.

Other parts used were; front lower basket seal, dryer seal, and dryer drum belt.

Had no problems except for keeping the drum belt idler pulley tension spring in place. Used the rear access panel to solve this issue.

Knob on dryer broke
Just removed the knob by hand and replaced. I couldn't find the part number on internet but your site showed the knobs for this dryer. The picture was the exact same as mine, eventhough it had a different part number so I ordered it. IT came in one day and was exactly the same. Thanks for the good pictures so I could compare the part.

Helping me with laundry, my mom pulled off the timer knob, snapping it off so it could no longer be used
The part number was easy to find, thanks to the schematics provided on your site. When the package arrived (faster than expected!) I simply had to replace the one which had broken off. It fit perfectly!

Small burn marks on light clothing
First I unpluged the machine, then opened the top with a flat head screw driver. Then I removed the two screws inside, unpluged the door sensor. (makes it stop when opened) Removed old gasket, cleaned with emery cloth, cleaned the residue and applied the glue provided. Waited about 1 min. and applied the new gasket leaving about 1/8'' of it hanging over the door facing the drum.

Loud Squeek while the dryer is running.
1. After checking the Parts Select website for some useful information I unplugged the dryer.
2. I popped the two clips holding the top down and lifted the top up and out of the way.
3. I used the 8mm socket and screwdiver combo to remove the two screws holding the front of the dryer on. These screws are so close to the sides of the dryer that you need something very thin to seat the socket, it is so thin a small rachet would not fit.
4. Once the to screws are free to forget to unhook the two wires that lead to the automatic cutoff switch on the right. Label them and move them out of the way.
5. The front of the dryer should pivot forward and come right off. Don't forget about the two clips at the bottom, they are not really attached to anything and can be easy to lose.
6. Get your screwdriver and dive into the drum, on the back should be three screws, take those out.
7. Spin the dryer around and take off the vent cover in the lower left corner of the back of the dryer, watch out the socket is a smaller size.
8. Once inside there is an idler pulley like on the back of a ten speed bike, pull the tension out of it and take the drive belt off the pulleys.
9. The drum should be able to be pulled out the front of the dryer, set aside with the door. The screws on my dryer were so tight I had to use a hammer drill to remove them.
10. This is were I got stuck, no one mentioned how to get the bearing plate off, as if everyone would just know. You must lift up on the bearing plate and once it moves up then you can pull it out.
11. Use the 8mm socket to unscrew the old plastic bearing guide. The small metal clip on the back of the dryer will fall off with the grounding ball bearing.
12. With brum bearing kit in hand start off by putting as much high temp lubricant as you can into the bottom of the new bearing guide. I also use a little lubricant like glue to hold the new grounding ball bearing in the little hole on the back of the bearing guide.
13. Here is the tricky part you have to screw the bearing guide into the the dryer while simulaneously holding the little metal clip in place on the back of the dryer. I used duct tape to hold the metal clip and once the screws got started I just took the tape off.
14. Now you have to do the impossible, the bearing must be screwed to the drum. So unless you have 7 foot long arms you can't hold the bearing and drive the screws. Another problem is the bearing itself, the holes are not the same size as the original and they are not threaded. I stripped every screw that came with the kit trying to get them through the metal of the bearing.
15. With an unwilling victim holding the bearing steady I finally got a replacement screw to seat through the bearing. Once you get one the rest are easier.
16. You are ready to reassemble, after vacuuming everything ou, pick up the drum making sure the belt is around the drum about where it was when you took it off. Push the drum through the front of the dryer all the way to the back, aim a little high so the bearing can move down and seat in the bearing guide.
17. Tuck the clips on the front panel of the dryer into the bottom front edge of the dryer and the whole front should pivot up, when you get it almost closed you will have to lift the drum and set it on the front bearing in the door.
18. While holding the front of the dryer on you have to reach inside and get the 8mm screw started on the left or right, if you let go the front of the dryer will pop off and you have to start over with the pivot. Now is a good time to have a magnet on a stick so when you drop the screw or screw driver you don't have to take the front off to retrieve your tools.
19. Once the front is on reconnect the two wires to the switch in the front of the dryer. Remember the ones you were supposed to have labeled earlier.
20. Close the top of the dryer and spin the dryer around so you can reach inside the vent door and pull the tension pulley over and reseat the drive belt. Rem

heat would initially come on then go off or sometimes not come on at all.
1. unpluged the dryer and turned off the gas.
2. pulled dryer out so i'd have ample room to work on it.
3. used large flat blade screwdriver in the front between the top lid and dryer face to gently pop-up the lid.
4. removed 4 screws from inside, that hold the face to the main box leaving the wires all intact.
Found the coils on the lower left, held in place by two screws and plate.
5. took a good look at thier orientation before unpluging old and installing new, I recommend one at a time.
6. Vacuumm any exceess lint and check foam seal between lint trap and exhuast duc, the glue came undone on mine causing extra lint dust that is potentially flamable.
6. screw dryer front back on to main box, make sure to check wiring harness and that all electrical blade connectors are still pluged in to their componants.
7. At this point plug in, turn on gas and do a test run.
8.if everything checks out good then lower top make sure flexable exhuast hose is still connected on hte back of the dryer.
9. Tell your wife or girlfriend or husband or boy friend they can now finish your laundry :)

Drum would not spin
After unplugging the dryer, disconnecting it from the vent, and moving into an open work area, I popped the top open with the blade of a screwdriver, disconnected the two wires that connect to the door switch, then lifted the front panel (with the door) up and away from the drum. Next, I lifted the drum out of the worn rear bearing assembly and lowered it into the dryer in order to release tension on the belt. I then removed the entire drum by carrying it forward and out of the way. I then removed the old bearing assembly, which was loose and covered with metal dust. After cleaning the area with a dry cloth to remove the old grease and metal dust, and vacuuming all the lint off *everything*, I installed the new bearing assembly with a 5/16" nut driver, being careful to position the provided ball-bearing between the plastic bearing assembly and the outer clip. The little ball-bearing is very important, as it is the drum's only path to ground, and prevents the build up of static electricity as the drums spins. I then filled the new bearing assembly with the provided grease. Everything is easy up to this point, but the difficult part for me was removing the old hub from the drum and re-attaching the new one. It is held on by three screws and they become seated very tightly. After loosening them and removing the old hub from the drum, attaching the new one prvoed difficult as well, as the screw-holes in the new hub are not threaded to fit the screws. The screws muct be forced to cut a thread as you install them, which requires a great deal of force. After installing the new hub and putting the new belt (pruchased separately) around the drum, the next step is to reinstall the drum by lifting it in through the front of the dryer and positioning the new hub over the new bearing assembly and pressing it down into place. It will gently "snap" into place as it seats. Then, on the back side of the dryer, I removed the vent panel by removing the two screws that hold it in place and positioned the new drive belt (loosely dangling around the drum) over the motor's drive wheel and behind the sring-tensioned idle arm. Then it is a simply matter to reinstall the front panel by genly lifting the drum and sliding the door opening inside it, then reseating all the little clips that hold the front panel in place. I then pressed the top back into place, reconnected the vent hose, plugged it back in and checked for operation. My fifteen year-old dryer now works like new!
