I followed the very informative video and wrote down step-by-step notes for myself. The repair went very smoothly. The only thing I didn't realize, was that the dryer has 4 rollers, not just 2 shown in the video. All are easy to access once you disassemble. I had to do it twice since I had to order 2 more rollers in order to replace them all. Also, the triangle plastic washers come with the roller, so you won't need to order them separately like I did. I also changed the idler pulley roller while I was in there since that has bearings too. Just as easy. I'm very happy with my quiet dryer! One last note: The new rollers are a bit louder than normal at first, but they quiet down very quickly as you use the dryer. It must be because they are brand new.

This could not have been easier. The hardest part was tipping the dryer over on its' side.
Instructions:
1. Tip dryer over onto a non-scratch surface. I used a tarp on the floor.
Insert leveling foot into the foot opening on the bottom of the dryer &
screw in with fingers until it is difficult to turn.
2. Use the adjustable wrench on the hexed foot (not the threads) to adjust to the desired level.
3. Tip dryer upright taking care not to exert pressure on the feet closest to floor. I used a folded-up tarp under the bottom edge of the dryer while lifting it to the upright position.
4. Use a level, back to front & side to side, to determine if feet need further adjustment.
5. Adjustments can be made with the dryer in the upright position, using the adjustable wrench on the hexed foot.

Replaced power cord, terminal block, and all melted wiring. Checked the thermal fuse for zero resistance.

Watched video & took my time. It went easy

Removed the front panel, removed the tub and removed the old seal. Tub seal area was scraped, sanded and wiped with acetone to ensure a clean. Bonding surface. Applied adhesive with and acid brush to get a consistent adhesive layer without getting too much in any one place. Seal was a bit smaller than the tub circumference so it had to be stretch to fit. While the adhesive was curing , I took the time to clean the contact surfaces and vacuum the lint from inside the cabinet. Reinstalled the tub, drive belt and front panel.

The pulley is accessible from the back of the dryer. Disconnect the gas line. Remove all the screws. Also remove the small plate that secures the line cord. Lift the back up and out. I was able to avoid disconnecting the water line. Take a picture of the pulley so that you will have a record of the belt routing. Release the spring and remove and replace the pulley and bracket. Vacuum out the lint. Plug in the dryer to make sure that it works properly before reassembly.

Took the top off and then front off and drum out . Replaced Drum roller and shaft support bolts.

Just follow the repair video, it was easy!

I followed the video provided by ‘Partselect’; although it was not the exact model it was close enough to get the job done with high confidence.

I followed directions found on several similar YouTube videos since the instructions included in the Whirlpool parts kit were not for my model dryer. I found that the original idler pulley was not rotating and the belt had worn a groove through it. I replaced all 4 roller wheels, idler pulley and the belt. Problem solved.

Unplugged the Dryer first. Removed the two screws from the bottom panel using a 1/4 socket and removed the panel by pulling down and out. Reached behind the blower and removed the connectors from the old thermistor and then the thermistor itself by removing the two 1/4 inch hex head screws. Replaced with new part and after screwing back in, reconnected the wires and replaced the panel. From start to finish, it took me about 20 minutes.

I removed the top first followed along with removing the side bracket that holds the circuit board. I then proceeded with removing the bottom cover and front panel. I disconnected the front panel from the control board and was able to slide the front panel upward. The door and blower housing was a bit tricky to pull out without thinking I was damaging something. I then replaced all the seals and cleaned the dryer after removing the drum and belt. I also replaced the drum support rollers. Afterwards I put everything back together and had an "E1" error and I pulled the thermostat out and wiped it down from all the lint and dryer worked perfect after that. Dryer takes the right amount of time to day clothes and no more rumbling noise. The instructions videos were VERY helpful.
