Dryer is heating up, making a soft buzzing hum sound, however, the drum is not turning. Also, has a something is burning smell

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.

When you start the dryer does it sound as if it is running but it does not tumble? Or does it make a humming noise?

If it sounds like it's running I'd check the belt first,
Humming noise and burning smell Dan indicate a bad motor or something stuck in blower wheel.

Two things are likely going on here,1- something is dragging down your motor check for a twist in the belt, idler pulley bad, belt installed wrong or wrong belt. Also check your front drum felt and glides if the felt is bunched up that will drag down the motor. Now the smell you probably have some felt or lint in the burner clean it carefully you do not want to damage your igniter.

Either something is binding the blower wheel up or the motor is bad. The best thing is to take the front of the machine off to access the blower wheel to verify ifanything is indeed binding it.IF not read the next section.
If you can turn the drum and then the dryer starts you have a bad motor. The way the dryer works is when you initially push the start button, electricity is sent to the start winding, or stator, of the motor. This will in turn start the motor turning. From there the stator will drop out of the electrical process and at the same time the run winding, or rotor, will take over and the motor will continie to run. Your stator is damaged, has a burn spot, etc so by you turning the drum, the belt around the drum is moved which is attached to the motor pulley. You basically take the place of the stator. Long story short, you have a bad motor.

check tub bearings and/or rollers or for anything that could impede the turning of the tub. Sounds like something is stopping the tub enough
to make the drive motor turn on the belt causing it to burn and smell.
If you fix the problem with the tub be sure and change the belt

If the sound is more of a hum than a buzz something has the motor in a bind or the motor has gone bad. Make sure you can turn the drum by hand and if you can not then check for something in the blower wheel.

Hi,
The motor on your dryer has gone bad. The humming is the motor trying to start and the smell is the motor getting hot because it is not starting.
You need to replace the motor.

When i put clothers in my dryer it does not move and it make a sound when i push the start buttom

It sounds to me like the motor is not turning, but the heating element is coming on. with no air flowing over the element, it is getting too hot. Can you operate the start switch with the top tilted up so you can see if the motor is turning but the drum is not, and just where the buzzing is coming from. Also, I would try the dryer on manual setting and on air dry to see if any setting works. Good luck

Can you turn drum by hand? If so you probably need a motor.
