I have a whrilpool gas dryer GGW9200LL1 and I recently changed the rollers and belt. Now, when the dryer starts it makes a loud thumping noise and I can smell a slight burning smell. I noticed that the right rear roller seems to be loaded by the drum and the thumping is coming from this area. Why would this happen after changing the rollers and belt. Any help would be appreciated. THANKS

Most likely the dryer drum rollers are worn out.

All dryers have some type of roller system that supports the drum as it turns. It sounds like one of the rollers or roller bearings has worn and is making that thumping noise. If you have some basic skills and good general mechanical sense you could fix it yourself. Make sure the dryer is unplugged before you attempt anything.

ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Sounds like your problem may be a broken belt, or the belt may have slipped off of the motor pulley, or idler arm pulley.
If you have to check/replace your drum belt and if you have a front loading machine.
Remove the electrical console that holds the timer switch, start switch, etc. from the top of the dryer. Be real careful not to knock any of the wires off of the timer switch or other connections.
Remove the lint filter screws and filter.
Then remove the top of the dryer.
Remove the front of the machine, this will expose the belt and drum, remove the drum and belt and this will expose the drum rollers, idler arm bracket with pulley, and motor with pulley. Pay attention to the route of the belt, this will come in handy when you go to reinstall the belt and drum.
Sometimes the belt will slip off of the idler arm or motor causing the drum not to turn.
While you have the drum out, I would recommend that you lubricate the drum rollers at the shaft of the roller with a good grade of machine oil like 3 in One oil. This will save you a problem later with the rollers getting noisy, also check your drum rollers for flat spots, if they have flat spots on them this will cause a noise like a thumping type noise. You will need to replace the drum rollers if they have flat spots on them.
Please rate me

greetings,
the most likely answer is the belt pulley..the rollers can also make noise,but they usually will make a thump thump noise..remove belt pulley and lubricate and see if this helps

a roller under the drum has a flat spot

Hello ENRIGHT11 Welcome to Fixya
My name is Huum,


You said,
DRYER MAKES VERY LOUD NOISE WHEN RUNNING. ALTHOUGH IT HEATS UP AND BEGINS TO DRY, IT STOPS RUNNING COMPLETELY AFTER ABOUT 5 MINUTES. IF YOU WAIT AN HOUR, YOU CAN START IT AGAIN, BUT IT AGAIN SOUNDS VERY LOUD (ALMOST A RATTLING SOUND) AND THEN SHUTS OFF AFTER 5 MINUTES

Faulty Blower Wheel
If you hear a great deal of noise coming from the blower area of the dryer when it is running, then the blower wheel could be defective.

The are many different designs for blower wheels and just as many unique failure modes. Vanes (fins) can break off the wheel and bounce around in the blower breaking more pieces. The blower can break around the coupler with the shaft. This can cause the blower to spin loosely on the shaft. The blower can form cracks which cause it to vibrate, etc.

You should also not be surprised to find foreign debris in the blower. The occasional bird, rodent or squirrel has been known to bypass the out vent cover. If they crawl into the exhaust tube the first thing they come into contact with is the blower wheel.

If the blower wheel is not spinning, or if it is missing vanes, it is not moving air efficiently. As a result, heat is not removed from the heat source and it can trip the high limit switch or blow the thermal cut-off.
Worn Belt
A worn belt can stretch and/or become brittle with age. The belt can then slip on the drum or motor to cause squeaking. If this is the case, the solution is to replace the worn belt.

The belt is not the only item that can cause squeaking. It can also be caused by a faulty idler pulley, worn drum bearings, worn drum glides or worn drum rollers depending on brand and style.

When replacing the Belt is is a good idea to also change the Drum Support Rollers, Drum Glides, Idler Pulley and Clips. All of these items are economical easily changeable when replacing the belt. The upside is that your dryer will operate like new.

Worn Drum Glides
Some dryer models are equipped with Drum Glides. The front of the dryer rests on these glides. They provide a low friction surface on which the drum spins. After time however, this glides wear down. Much like an automobile brakes, these glides make a load grinding noise when they wear thin. This griding against the drum usually leaves a bare metal stripe that is visible at the point of contact. If the glides are worn, the solution is to replace them.

The drum glides not the only items that can cause squeaking. It can also be caused by a faulty idler pulley, worn drum bearings, a worn belt or worn drum rollers depending on brand and style.

Worn Rear Drum Bearing
Some dryer models are equiped with a Rear Drum Bearing. The rear of the drum rests on this bearing. It provides a low friction surface on which the drum spins. After time however, this bearing will wear down. If the bearing is worn, the solution is to replace it.

The rear drum bearing not the only item that can cause squeaking. It can also be caused by a faulty idler pulley, worn drum glides, a worn belt or worn drum rollers depending on brand and style.

Worn Drum Support Rollers
Some dryers such as Whirlpool/Kenmore brands are equipped with Rear Drum Support Rollers. The weight of the dryer drum rests on these rollers. They provide a low friction surface on which the drum spins when in operation. After time however, these rollers wear down. When they wear, often times they begin to elongate and form a non-round 'cam' shape. The result is that when the dryer is turned on it creates a rumble that sounds as though you are trying to dry a pair of tennis shoes. This sound is usually the drum being forced up and down on the non-round wheels. If the rollers are worn, the solution is to replace them.


When replacing the Drum Rollers it is a good idea to also change the Front Drum Glides, Drum Belt, Idler Pulley and Clips. All of these items are economical and easily changeable when replacing the glides. The upside is that your dryer will operate like new. Whirlpool Kenmore models have a dryer maintenance kit that contains all of these items in a single kit.

Take off the back panel of the dryer and look at the motor and belt turning the drum. There may be something caught on the drum and is pinned in place causing the noise. The motor could be loose on the platform and needs to be tightened. It is probably something physical and seen causing the noise.

no and its your rollers...babump babump...

We had the exact same noise all of a sudden start coming from our 2 year old dryer. We checked everything, rollers, pulleys, motors, etc. I was certain it was coming from the upper left. Finally we found a loose screw had fallen into the front felt ring. Problem solved!
Good luck.
