My dryer sounds like there are metal balls rolling around inside when clothes are drying

Nicky,
Do you have moisture sense on this dryer? Also, do you use dryer sheets? If the question is yes to both, look for your moisture sensor strips inside the drum. They will be a couple of metal strips that may be straight or curved and they will be spaced about 1/2" apart. Get some rubbing alcohol and several cotton balls and wet one of the balls and rub the metal strips. If it comes back blue, keep cleaning with the alcohol and cotton balls until they come back still white. Some dryer sheets will leave a residue on the sensors and it makes the dryer think that the clothes are dry and they cannot sense the moisture. Hope this helps!

I heard the sound and that is not an unbalanced drum. I think you have either bearings going out or your drum belt needs to be replaced. When that wears down it causes the drum not to run true giving it that metal on metal sound.

As you insert the clothing into the dryer make sure you open up the larger pieces fully so they do not ball up. Frequently people put large bed sheets in before opening them up and everything gets rolled inside them. If your load is too small, that might happen, also!

Dryer Repair Squeaks, Grinding, Clicking and Knocking Noise

An unusual noise coming from a running clothes dryer can cause concern, although these noises are rarely indicative of a more serious problem. Once the source of the noise has been located, a few simple repairs or adjustments will usually solve the problem and restore peace to your laundry room.

Gas
1. A gas dryer may emit an occasional clicking sound. This noise is caused by the gas valve and is a normal operating sound. The clicking sound coming from the gas valve can not be eliminated and it does not indicate any mechanical problem with the dryer.
Warm Up
2. A newly installed dryer, or a dryer that has been left unused for a period of time, may exhibit a thumping noise during the first few minutes of the drying cycle. According to the Maytag company, this noise is normal and should not be a cause for concern. If the noise continues for more than a few minutes or repeats on subsequent loads, however, then steps should be taken to locate the origin of the noise.
Clothing
3. Clothing can become knotted and balled up in the clothes dryer. This can cause vibration or a load thumping noise. When this happens, open the dryer and remove the knotted clothing. Separate the articles of clothing and place them back in the dryer. The thumping noise should not continue unless the clothing has become knotted again.
Vibration
4. Place your hands on top of the dryer and push down firmly; if the dryer tilts to one side, the clothes dryer is not level. This can cause the dryer to vibrate during the cycle and if the vibration is severe enough, the surrounding walls could be damaged by the dryer. Maytag dryers have four leveling legs installed into holes on the bottom of the dryer. These legs are included with the dryer and should have been screwed into the holes during installation. A wrench can be used to adjust the legs until the dryer is stable and level.
Foreign Objects
5. Small objects such as coins, buttons, or paperclips can become lodged between the drum and the sides of the clothes dryer. These items usually end up in the dryer after being left in clothing pockets during laundering. Turn the dryer off and remove any clothes to a laundry basket. Allow the dryer to cool down so that you won't burn your hand on any metal surfaces inside the dryer which may be hot. Look inside the dryer and pay special attention to the front and rear edges of the dryer drum. Run your fingers along the grooves where the drum connects to the dryer to locate any foreign objects. These objects could be bouncing around the dryer causing noise during the cycle, and then settling into the grooves when the dryer stops making them difficult to locate. Remember to remove all items from clothing pockets before laundering in the future to avoid this problem.

sounds like your blower wheel (fan) has broken and is spinning around on the shaft of the motor.

that's actually a really easy fix....the dryer should have 4 roller wheels that the drum rides on and one or more of them must be worn out that is where your noise would be coming from.

Sounds like out take, something blocking the vent, pinched line, birds nest, snow?

Just get the filter out and remove the 2 phillips screw init's housing on top. Then use a putty knife to press against the spring clips that hold down the top Then just roll the drum around to the top where the holes are to reattach the baffle, get some screws and put it back.
