Product Description

Multi Rib Belt Specifications

This dryer drum drive belt attaches to the motor pully and works the drum as the motor rotates. The belt has a length of 93- 3/6 inches, and wraps all the way around the dryer drum, around a tension pulley, and then around the drive motor pully. Replacing the rib belt could solve symptoms such as a screeching noise when the dryer tumbles, a broken belt (dryer will not tumble if its broken), no heat or not enough heat, or the dryer will not start. The tools needed for this repair are a nut driver and a putty knife. Remember to unplug the dryer before installing the part and protect your hands by wearing gloves.

No Heat from Electric Dryer
I had recently had the low limit thermal fuse replaced for the same problem. About a month later same problem but different fuse. I checked the low limit fuse with an ohm meter and it had continuity. When I checked the High limit fuse it did not, there was infinite resistance meaning it was open and not providing current to the heater elements. Out of concern why the high limit blew, I decided to replace the thermostat as well. As I dissembled the dryer there was an over abundance of lint from years of use. I also notice the drum belt had some chunks missing and decided to replace it since I was removing it anyway. Ordered the parts from Part Select and they arrived in a timely manner as promised. Replaced the defective parts, vacuumed out all the lint and junk that was coating the drive motor and other items. Resembled the dryer and it worked good as new. total cost of $60 in parts, and couple of hours and back in business!

loud screeching noise, motor seized, long time to dry
disassembling took about ten minutes. found that lint needed to be cleaned out. idler lever pulley was locked up and the belt had worn the pulley down. guide felt pads were off the drum guides. motor seized up. studied videos and ordered parts for each problem. once parts arrived the total repair took a total of 45 minutes. saved $300-400, and did not have to buy a new dryer. dryer working better than it has in four or five years, heating up better and no noise. would recommend buying own parts and replacing. on a scale of 1-10, this is a 2. this is an electric dryer. hope this helps!

dryer made squeaking noise when first starting to run
I first watched the video and disassembled the dryer to see if I could determine what part was squeaking. All looked good except the wheel on the Idler lever which was tight. I vacuumed up the years of lint and reassembled the dryer and waited for the parts to arrive. I ordered the idler lever and also the 2 drum support wheels, belt and 2 drum guides since I thought that is was a good idea to go ahead and replace these parts once I had the dryer disassembled again. Good choice on the belt as once I removed the old belt there was a crack on the underside of the belt. I bought snap ring pliers at home depot but the tips were too big to fit the holes on the snap rings on the drum rollers. I bought another snap ring plier set from an automotive store that came wth 5 snap ring attachments - but again all were too large to fit the snap rings on the drum support rollers. I used a nail and small screwdriver to expand and pull off the snap rings but this approach was frustrating and time consuming. Not sure where to get snap ring pliers that are small enough to fit the holes on the snap rings - so hope that you have better luck locating a set thats small enough! I was able to return the pliers that I purchased - so all good. I was surprised at how easy the dryer came apart and how easy it was easy to work on. When disassembling the dryer - we took pictures of the wire connections before we disconnected them, however at one point we tilted the dryer back to clean behind it and the top slipped a little away from the side panel of the dryer and one of the wires that was connect to the wire block that is up by where the power cord connects cam loose - and it took some time to find and figure out a wiring diagram for this connection. Suggest that you take a pictire of this wire connection block once you lift the lid - just in case a slip occurs and a wire may disconnect. When replacing the idler lever -
have a little grease available when you install the new idler lever (between the arm and the bolt area as it constantly moves and the old brease has probably worn away) . After making these repairs I dont think I will ever buy a new dryer as any part , including the heater and motor would be easy to replace and cheaper than a new dryer.

Drum stopped turning, motor still running
Dryer stopped tumbling, so bad belt was my first thought. Dryer is in vacation home so did not have immediate access to it to diagnose. Ordered belt and discovered that the poorly designed motor pulley had broken and the belt jumped onto the motor shaft and burned through the original belt. Week 2 after ordering pulley, installation went per YouTube video. Glad I also replaced the belt because it was brittle and cracked. Suspect it had been slipping because sheets would ball up into a log, possibly because the drum wasn't spinning fast enough. Anyhoo, after repair all seems OK.

Dryer drum would not turn under load
I watched the repair video and followed the instruction given to replace the belt. The instructions were easy to follow and to the point. The one thing that was not covered was to vacuum the interior prior to closing the dryer up.

Hi, my dryer is emitting a burning smell this happened one before and I replaced the belt (which fixed the problem) but now it is happening again. Should I be replacing something else or could the belt be faulty already??? Thanks
PartSelect logo
Hi Lorna, great question! Based on your symptoms we recommend checking the idler pulley and rollers on your dryer for tightness. If they are quite tight they should be replaced, and that should stop the burning smell. Please let us know if you have any further questions.

I bought this part and I am replacing the old belt. I see a few groove options to wrap it around, one is prettttty deep and the other seems just out of reach? Which do I use?
PartSelect logo
Hello Rene, great question! The belt does not usually slide in a groove, it is simply wound around the drum. When the belt is installed try turning the drum slowly to let it align properly. Best of luck with this repair!

So my dryer goes hot and sometimes tumbles, but sometimes it is very slow and other times it is normal… from what I can tell. Reading around I thought to change the belt but now I dont know if that will fix it. Thoughts? Advice? Help?
PartSelect logo
Hello Avery, our advice to you is to first check the rollers on your dryer to make sure they are not seizing up and sticking. This could be caused by excessive wear and visible damage. I hope this helps!

The dryer will not turn unless I lighten the load inside. Anything more than a few items and it refuses to spin. Is it the belt or something else?
For model number Sdg3606aww
PartSelect logo
Hello Richard, Thanks for your question. Usually this is due to the belt, assuming the clothes are not over-capacity for the dryer. You may also want to check the drum glides to see if they are intact, along with the idley pulley wheels. I hope this helps.

My dryer is not geting hot
PartSelect logo
Hi Michael, Thank you for your inquiry. There are some parts that you will need to check to see which one is causing the issue. If you have an electric dryer you will need to check the heating element, the high limit thermostat and the cycling thermostat. If you have a gas dryer you will need to check the igniter, the radiant flame sensor, the gas control valve and the coils. There are some other parts you will need to check as well. They are the temperature sensor, the timer and the thermal fuse. I hope this helps. Thank you and have a great day!

My dryer was making a loud squealing sound so I took it apart as per your videos but how do I know if the belt is bad or if it is the rollers or the idler pulley? I do not know how to tell if they are good or bad.
For model number MDE308DAYW
PartSelect logo
Hello Mike, Thanks for your question. A bad squealing noise is typically due to bad rollers or the idler pulley. Inspect the rollers and the pulley for any signs of wear or damage visually and replace them if they are damaged. I hope this helps.

My dryer won't start. If i press the knob to start it, it just makes a loud noise like it's trying to start but the drum does not move. If i turn the drum then try pressing the knob it will start up for a minute but quits again. Then only makes the same noise if i try again.
For model number CYE3005AYW
PartSelect logo
Hello Starla, Thank you for the question. The first thing to check is the belt to ensure it is not wore out and lose and able to grip and tumble the drum. In most cases with a loud noise and no tumbling or a slow tumble, the motor would be defective and needs to be replaced. Hope this helps!

For model number MDG308DAWW and SER#11806493JR
PartSelect logo
Hi Mario, thank you for your question. When you are experiencing an issue like this there are a few parts that you will have to test to determine what is causing your issue. For all of these parts you can test them with a multi meter. First you will have to test your thermostats and thermal fuses to make sure they are all functioning correctly. After that you will want to test parts in this order, your m series coils, igniter itself, or your radiant flame sensor. You may also want to check your regulator just to make sure that part is functioning properly as well. Something else you should also check would be your filter and ducts. Make sure there is absolutely no blockage that would restrict air flow in your appliance. I hope that helps. Good luck with your repair.

Just replaced belt and it still squeaks,any help?
For model number MDE508DAYW
PartSelect logo
Hello Gary, Thank you for your question. If you have just replaced the belt and it still squeaks, there could be a couple of causes. It could be that the belt was installed with the grooves facing out which is allowing it to slide on the drum. However, the most likely cause would be a lack of tension on the belt. I would recommend double checking the belt path and that the idler is installed correctly and providing tension on the belt. I hope this helps!

For model number LGA30AW

Hello Steve, Thank you for your inquiry. We would recommend checking the following parts to fix your issue: high limit thermostat, cycling thermostat, "M" series new style coil kit, radiant flame sensor, thermostat boosting heater, and the door switch kit. You can test the parts with a multimeter. Hope this helps!
