DRYER IS MAKING A CONSISTENT BANGING NOISE WHEN RUNNING. DRUM IS TURNING AND DRYER DOES DRY OK.

If you have an older Kenmore dryer, the drum bearing and/or rollers may be failing. This would cause the drum to rotate unevenly (wobble) and possibly contact the heating elements on the rear panel. This would account for the banging noise and burning smell. Your dryer has to be serviced.

Most of the time a tumble dryer will work like a dream but, as with all appliances, occasionally there will be technical problems.
If your tumble dryer is making a banging, whining (or other strange noise) it's best to diagnose and sort out the problem. It could be the result of a number of things, but what you certainly don't want to do is ignore it.
Here are the most common reasons for your tumble dryer making odd noises.
Coins and keys
One of the most common reasons for a banging, rattling or clanking is keys or coins left in pockets - so always check them before you put any clothes in the tumble dryer. More often than not you won't hear anything until the dryer cycle is in full spin.
Uneven surfaces
If the dryer is vibrating or shaking during spinning, check to make sure the dryer's sitting on a level surface. If it's fitted with height adjusters on the front legs, adjust them accordingly to ensure the machine is level as this will often reduce or eliminate the banging sound.
Drum bearings
If the tumble dryer is noisy when its turning and the whole appliance is shaking and rumbling, it could be indicative of a problem with the drum bearings, which help the wheels turn freely and easily.
The drum
If the banging noise is continuous when the drum is turning then it might be problem with the drum itself. If the noise is a metallic one, it could be the result of the drum scraping on something inside the machine. You could always check the drum visually for any marks or dents.
Motor bearings
If the tumble dryer is emitting a high-pitched screaming or whining noise it could be a sign that the motor bearings are wearing out.
Tension pulley wheels
If there's a squeaking noise coming from the dryer it could be the result of wear on the tension pulley wheels. This occurs more frequently on older models...or try this link..
Common Tumble Dryer Problems

the timer may be stuck at a certain place as they have points that at times tend to burn out and stick when the timer gets to that point. do the other settings work? some times the moister sensor will not sense dry clothes and keep running? as for ur drum noise that may be due to bad rollers or bad tensioner and belt depending on ur model and hopefully not bad bearings also a possibility

GOD IS GOOD !!!!

DRYER MAKES NOISES.



A loose or worn BELT can make funny noises

Or the idler pulley that puts tension on the dryer drum drive belt could be worn out. If the pulley is bad we recommend also replacing the belt.



The glides on drum worn and making metal to metal contact.

The drum slides or glides support the front of the drum. As the drum rotates over the years, the glides wear out and then the dryer makes noise. Replace all of the glides as a set if they are worn out.



CHECK FOR LOOSE BELLOES inside the drum



Sometimes an item can get stuck inbetween the drum and the housing and scrape and grind making funny noises, things like coins, bra wire, nails, hair pins, etc sometimes u can just remove the cabinet and observe by turning the drum by hand or looking for scratch or scrape marks on housing.



The blower:



Clumps of lint, socks, and other small articles of clothing can get past the lint filter and into the blower wheel. If the dryer makes noise, and the noise seems to be at a very fast pace, there might be something caught in the blower wheel. In addition, the blower wheel sleeve might be worn out, allowing the blower wheel to wobble on the motor shaft. If this happens, replace the blower wheel.



The bearings:

The drum bearing supports the rear of the dryer drum. If the dryer makes noise this bearing might be worn out. Replace the bearing if it is worn out. Do not lubricate the bearing, the lubrication will attract lint and dirt and accelerate the wearing process.

The bearings TEST by moving drum by hand u may be able to feel loose or rough movement. And listen to sounds when turning it.



The drum rollers or castors:



It is very common for dryer drum rollers to wear out. If the dryer makes noise, particularly a loud rumbling noise, one or more of the rollers may be worn out. After removing the drum from the dryer, inspect the rollers.

Check for cracks, dryness, or damage and not engaging drum properly. Sometimes u can use high density LITHIUM BASE gear grease to re oil/grease them.

First, check the vane's (paddles inside the drum) to see if one is loose. Post back the results.

Maybe the heat in your dryer over time has melted weak glue and loose components are hitting against the drum

Mine did that and had to have the washer re-balanced.

Hi,
Here is a tip that I wrote about dryers and noises...
It will help you determine what is happening there...

Asker's Testimonial " This should give me an ida of what to look for once I open er up " -

the problem is with its motherboard .. i too had the same problem.. ask the repairing persons to change the motherboard if it is warranted. ( but there is no other way)..

You may have had a foreign object slip under a loose drum baffle. Manually rotate the drum to locate wwhich baffle it is in.
