MGD3100DW0 Whirlpool Dryer - Instructions

You tube and supplied video directions for the make and model. Follow step by step and the repair went easy. Worried when removing the dryer drum but it went smooth.

I used your great video for pointers as to what to do. I took off the front, raised the top, vacuumed the whole thing up, that took quite a while. Took out the drum. Did more cleaning. Then took off the old retaining rings with retaining ring pliers, took off the old drum rollers and support. Replaced with new roller supports, washer, roller, washer and retaining rings. Then I replaced the belt. Tested it and turned the wrong way and it came off. Replaced and tested it again and I don't know why but it came off. Replaced the belt again, tested fine. Then I replaced the felt pads and glides, they were worn. I ended up asking my husband to help hold the drum so I could get the front back on. Replaced front and door. Tried the dryer. Works great AND very, very little noise. Note: when taking the wiring off the light and the door switch, I took photo's of those places with my cell phone and had them to look at to make sure the wiring was correct.

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.

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.

Couple screws behind the electrical panel at the top and the top pushed back and was able to remove front panel, and then it was pretty easy. Take the two screws on top front, lint trap screws . The lint trap vent needs to come off. Then the belt, drum comes out to access the idler pulley. I did replace two drum wheels, I saw there was 5. I would recommend replacing all of them, they didn’t move well…..

I took off the back panel off the dryer. The idler pulley could be accessed on the bottom. It was a bit cramped but not too tough to replace.

I thought I had checked the arm piece of the rack real good for a product number on my original part but I missed the number till the 2nd box came in, and a looked real careful and realized it was the same as the order I thought was bad.
Put the spring arm in first and the rack will fit in the front groove.
It would have been good if there had been a picture of the dryer arm attached to the dryer.
So I have 2 good racks and will return one if you tell me where to send it.

Pulled dryer out from the wall and measured the distance between dryer and outlet and made the necessary cuts to proper length then installed it , moved dryer back into place . ready for clothes and no duct problems.

Lubricated pulley wheel which temporary reduced noise. This verified what was making noise. Looked up the part on partselect.com and ordered it. Recieved idler pulley with bracket in just a few days.
Quickly removed back panel using nut driver with drill. Slipped belt off pulley, removed one screw with plyers to released spring and removed old assembly.
Inserted new assembly, connected spring, slipped belt back on roller.
Tested before replacing back panel.
All was very quiet. Replaced back panel.
All done

Pulled the back panel off with nut driver , reached in removed belt from pulley , disconnected the spring , removed the the 1 bolt holding the bracket .
Put the new one in , in reverse order . Very simple , maybe 15 minutes total . While back is off , shop vac out any lint !!

Followed video on PartsSelect website, they made it real easy.

Lowes gave a conversion kit for 29" wide dryer, not by model number. Could not find the right kit. Called PartSelect , in 2 minutes they had the right kit, by model number. Sent overnight mail, followed direction and boda bing it was done.

Lint can build up inside the dryer, and can cause a fire in EXTREME cases. If your model has a back panel that exposes the entire chute, this job is much easier. Unscrew the chute from the machine to remove it. Inspect and clean all the lint out, especially the bottom, next to the fan blower. The other version machine has a panel at the top that is welded on. Remove the two screws at the top corner of the rear bulkhead, where the chute is. Gently pull this inner panel away to free the top of the chute from the rear top panel. Then pull the chute down and out. Follow the reverse to complete the job.

Removed rear cover (6 screws) unpluged harness from motor control and removed same. Replaced motor control reinstalled harness. Replaced rear cover. Parts used motor control board.

Once I watched a YouTube video showing me how to do the job I ordered the part from you. Am so impressed with your fast shipping and best prices via the Internet. Thank you SO much! The water level switch was easy to install, it ws getting the cover on the washer back on that was hard for me since I am 68 yrs old and have a bad knee. Its why it took me two hours to do what most people could do in 20 minutes.
