Dryer drum would not turn
Ordered $245 worth of parts for four possible fixes. None of the four fixes worked. Used an appliance repair person to do more troubleshooting. Fourteen days later and after spending an additional $380 ($625 total), a new control panel was installed. That solved the problem.

Annoying loud metal to metal screeching noise.
Took the front part of the dryer out, released tension on the idler pulley, took the drum out, and remove the old drum seal. Make sure you remove the old adhesive with sandpaper or wire brush. Put the new adhesive on the seal, not on the drum. Adhesive is very runny. Seal may need to be stretched to fit the drum. Set the seal on the drum, let sit a few minutes. Put everything back together.

The belt you sent was too short
I disassembled the dryer, replaced the pulley (which was noisy), and the belt.reassembled, only to find out that the drum would not turn freely. checked all my procedures and kept having the same problem. Finally after 3 frustrating hours, I took the back off and noticed that idler arm was tight against the motor shaft, because the too short belt didn't allow for the clearance needed. Had too take everything apart ,another hour, went and found one at our local repair shop, reinstalled everything , after another two hours runs fine. would appreciate a refund. And please check your part numbers in the future. Would hate to have someone else go through what i experienced.

Dryer starts with loud squeak initially. Eventually there was a loud clank and dryer stopped.
Rather than remove the front panels, door, control panel and drum, I noticed 1/4" metal screws on the back panel. There were approximately 6 holding the back panel in place. I did have to remove the top panel as well before removing the back. Once removed I had complete access to the broken idler pulley assembly. I immediately saw the broken pulley. I installed the new one with very little effort. Reset the belt according to instructions from the video. Reassembled, plugged in, hit start and enjoyed the sweet sounds of success. All told it took me about 20 minutes from start to finish.

Idler pulley was frozen on the shaft.
Removed the top, front cover, drum and belt. Removed the idler pulley bracket and pressed the frozen pulley from the shaft. Cleaned the shaft and applied a small dab of anti seize and replaced the pulley. Installed all parts in reverse order. Dryer works like new again.

Replacing my idler pulley and I feel like it might be too small. The other one comes off and on easily however this one is giving me a lot of trouble. I hate to say I might’ve got the wrong one, but when I went in store they said it is the correct one for my model. So do you have any tips to make this installation easier
PartSelect logo
Hello Wes, we recommend replacing the idler pulley and the idler bracket together as one assembly. You can order the kit here W10837240. I hope this helps.

Replacing the idler pulley bc of excessive squealing. Does this repair need lubricant? It looks like on my old one there was lubricant but just wanted to make sure before I put it on
PartSelect logo
Hi Nic, you can only use a dry lubricant in dryers, examples of this would be baby powder, or corn starch. However, for this repair you do not necessarily need lubricant, as they are normally assembled dry. Best of luck with this repair.

I confirmed that this is the idler pulley for my make and model dryer before buying it. But when it arrived its thinner and a little bigger around- is it safe to use???
PartSelect logo
Hello Julian, this idler pulley was recently redesigned by the manufacturer, which is why it looks different. However, it will still work for your model. Please let us know if you have any further questions!

The video you show on replacing my part shows a different dryer than what i have.

Hello Bob, thank you for your question. The idler pulley is used on many different styles of dryers. The dryer might be different but the installation video should provide the same instructions for your unit. I hope this helps!

While observing my dryer drum i noticed that the belt wanders forward (toward door). At this point the drive motor stalls causing dryer to stop until the motor cools. If i move the belt backwards the dryer functions normally. My thought was that i may need to replace the belt and/or the pulley assembly. Can you please help me? Barry grimm
For model number GEQ8858JQ1 (electric)
PartSelect logo
Hi Barry, Thank you for your question. Based on what you described, it sounds like the belt may be worn and stretched and it may be replaced. I would also check the pulley to see if it securely fastened. If it is worn or damaged you will need to replace it. I hope this helps. Thank you and have a great day!

My dryer squeaks for the first 30 seconds or so. Sometimes more often then others especially when it first comes on. I assume it's the belt tensioner pulley or possibly the drum rollers. I bought the whole kit with the pulley, belt, and rollers. I'm hoping you have a video or at least some tips on replacing it before I tear into it. I've done it on an older dryer before but nothing this new.
For model number WED8500DC1

Have a Whirlpool cabrio dryer. Ordered the idler pulley part # 279640. Wheel is a little bigger in dia. But this is no problem. But i can't get to slide on pulley bracket arm. The center opening visually appears the same as the one i took off. But i can't even force it on. New idler center opening is to tight.
For model number WED5600XW0
PartSelect logo
Hi Tim, thank you for your question. I would suggest taking a look at our installation video here: https://youtu.be/y011lnwfx6Q. If that is not enough you might have to buy the whole part already assembled. I have linked the part below for you. Good luck with your repair.
