Samsung dryer DV4015J belt keeps breaking

This is the third belt that I've replaced in a short period of time.
Any suggestions? The quality of the new belts seem poor. Is there a better belt that I could use to help frequent breaking?

Replace the belt on pulley assemblyfor dryer dv4015j

There are plenty of YouTube videos on how to do this. The dryers are made by different manufacturers and are designed differently though. Watch the beginning of as many videos as necessary until you find one that comes apart the same way yours does. When you find that, everything inside will be the same too.

Hi, My model is WED5300SQ 6.5 CU FT S Whirlpool electric dryer. My belt keeps breaking. This is the third time within a 18 months. Are there any recalls or defects in this model? It's easy to replace;...

That belt ought not to break for 10 years. I use zoomspout oil because it is safe for dryers. Lube your rollers and idler and if your idler is a crappy one without the roller you needs to chunk that one.themobilian_1212.jpgthemobilian_1213.jpg
Check inside your blower for junk

I have a manual or 2 and some videos with more repair photos HERE

Samsung dryer DV4015J turns on and motor sounds like its working but the drum does NOT turn so clothes do not dry, they just sit in dryer container?

If this is the older type, then the dryer drum is rotated by a thin loop belt that goes around the drum and then a pulley on the motor. I had to replace my 20 year old dryer belt on a Whirlpool a couple years ago. The front comes off and the belt slips over the drum. The front of the Whirlpool is held on by friction clips that have to be pried off with a flat blade. I suspect that you can do the same. look on the internet for a diagram of your dryer or you may have one in the manual that came with the machine.

Samsung dv4006 dryer belt

Possible replacement belt quality problem for the Samsung DV4006 / DV4006J / DV4015J / DV665JW and the Maytag MDE2400AZW dryers:

The original belt for the Samsung DV4006 / DV4006J / DV4015J / DV665JW dryers is a Megadyne 1975 H7. The part number is DC66-00121A, but when ordered, a Dongil 7PH1975 belt may be shipped instead of the original Megadyne. The Maytag MDE2400AZW dryer uses the same belt. The part number is 35001010, but when ordered, a Dongil 7PH1975 belt may be shipped. It seems that the Dongil belts are inadequate for these dryers. They delaminate and may fail prematurely. Even new, they cause a thumping sound each time the seam goes over the motor pulley. Other than Megadyne, another good belt is the Hutchinson 1975H7. The appliance part number is 1258288107.

Where to get an original Megadyne 1975 H7 belt:

eBay member 'appliance-parts' in Colorado, USA has emailed me that their Samsung DC66-00121A belts are Megadyne. Website: Email address:

eBay member 'ladydi1975' in Ohio, USA has emailed me that their Maytag 35001010 belts are Megadyne. eBay store: Discount Appliance Parts.

Where to get a Hutchinson 1975H7 belt:

eBay member: 'zodiac300_0' in Brighton, United Kingdom. I have ordered a 1975H7 belt from them and received a Hutchinson.

Other possible causes for belt failure:

--Motor pulley designed too small. The belt may be flexed beyond it's minimum rated radius.

--Excessive heat in the dryer due to lint in the vent line or vent line too long. The Dongil belt may be less heat resistant than the Megadyne.

--Worn drum bushing DC66-00062A.

--Metal burrs on the steel motor pulley. Deburr by inserting a small screwdriver in each groove while the motor is turning without the belt.

--Belt on the wrong track. The motor pulley has nine grooves and the belt has seven ribs. The belt must be in the middle. It's easy to place it one groove forward or backward by error.

--Small scratches on the drum where the belt contacts it. The scratches may be like small knives and damage the belt. Sand with a fine sandpaper.

--Idler pulley damaged or bearing worn.

How to replace the belt:

--Remove top cover.
--Remove vent panel (in back).
--Unclip door switch from front panel.
--Disconnect wire harness from door switch.
--Unscrew panel left of control console (from behind the panel).
--Unclip panel left of control console (from behind the panel).
--Unscrew control console.
--Unclip plastic panel on bottom, front
--Remove screws behind door. Remove door.
--Unscrew large front panel, remove.
--Inspect vent line for lint buildup, drum bushing (back of dryer) for wear, motor pulley for burrs and debris, drum for scratches, and idler pulley/bearing for damage.
--Vacuum all lint.
--Install belt around drum, idler pulley, and motor pulley. The ribbed side of the belt contacts the drum. The flat side of the belt contacts the idler pulley. Press on idler pulley to stretch the spring, and line up the seven belt ribs in the center of the nine motor pulley grooves.

How do I get to the belt

These are not the "same" problem.

1. The squeak typically will be from dryer fuzz getting into the mechanism. If you MUST spray WD40 then watchout where you spray it. If you get it on the belt then the belt will degrade and break in a very short period of time. If you spray WD40 on electronics they will probably short the electronics. It may also be a worn out pulley or motor bearing.

2. You must remove the pulley bolt on many dryers, place the belt on the pulley and then thread the bolt back on the arm or nut.

3. Most of the Maytag washers you must remove the doors first and then there are clips that hold the frame together. They are "pop off" with a scredriver and a bump with a gloved hand.

4. see 3. to get the cabinet off. If it sounds like a bearing then it probably is and you will have to replace the pulley and integrated bearing. It may also be a worn-out motor bearing (replace the motor).
