Question about Samsung 7.3 Cu. Ft. Electric Dryer
OK, I finally figured it out... The right-hand side of the belt loop is the one that routes around the left side of the idler pulley. You have to pull the belt around the bottom of the drum and then over top the idler pulley, then back down and around the motor pulley. It's not all that obvious...
Don't have time to run this thing to find out how well the belt holds up, but will look to report back if/when I do: it's now a "spare" dryer, and I'm not really in a hurry to swap dryers for a test right now.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

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: http://appliancefactory.com Email address: firstname.lastname@example.org
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.

SOURCE: I need to see how
It sounds like you have a bad or broken belt tensioner. It is located in the bottom of the unit close to the motor . It is a spring loaded pully assembly which keeps the belt taught. The belt simply goes around the drum and the motor shaft and the belt tensioner pully.

Check to make sure your child lock is off first. Hold the time and signal buttons simultaneously for three seconds. Unlikely, but do check. Some of these dryers have a safety switch that the idler pulley has to engage to allow the dryer to run. I tried to find a schematic for this model but could not get one to tell if you do have a safety switch. Look at the arm of the idler pulley and see if it is contacting the switch actuator correctly. When a belt breaks or pops off, sometimes the arm of the pulley will move to the other side of the switch actuator and will not allow the dryer to run once a belt is reistalled. I would also look to see if a wire was knocked off of the motor switch when your belt came off. Good Luck, Appliance Specialists

SOURCE: Dose the dryer belt have
The grooved side should be in contact with the drum as well as the drive pulley. And blank/flat side of the belt should be in contact with the tension pulley.
