Motor malfunctions usually call for service by a professional. There are three main causes of motor failure: lack of lubrication, a defective motor switch, or worn or frozen bearings. A humming sound can be related to a burned-out motor or a defective switch. Check these trouble spots before you call a professional service person or take the motor to a repair shop. Here's how to check a dryer motor:
Step 1: Remove the back access panel. Then reach behind the drum, motor pulley, and idler arm pulley. If these areas are clogged with dirt and lint, undue strain on the motor may be causing the humming noise. Worn or broken belts can also cause a humming noise. Check the belts for wear and damage. If the belts look all right, you may be able to stop the noise by spraying them with fan belt dressing, available at automotive and hardware stores and home centers.
Step 2: Turn the dryer on. The noise you hear may be the whirl of the spinning drum, not the motor. Some noise is normal.
Step 3: Force a little 20-weight nondetergent motor oil (not all-purpose oil) around the ends of the motor shaft. This lubrication may stop the humming noise. If this doesn't solve the problem, remove the motor and take it to a professional service person.The centrifugal switch on the dryer motor may be located on top of the motor. Humming, no motor power, and no heat can be caused by a faulty centrifugal switch. If the switch is externally mounted, check the terminals of the switch to make sure they are tight and not burned. If you spot trouble, remove the switch and take it to a professional service person for testing. A faulty switch will probably have to be replaced. Some centrifugal switches are located inside the motor housing; you won't be able to remove the switch in this case. Remove the entire motor and take it to a professional for repairs.
If the motor hums, but won't run the pulley on the end of the motor shaft, try turning the pulley by hand.Caution: Before turning the pulley, make sure the power to the dryer is turned off.

It sounds like your belt needs to be replaced. You're smelling the melting (burning) rubber.
SOURCE: Thumping/Screeching sound, MD:LDE8616ACE. Rollers? Idler Pulley?
Your description sounds like one or both of the rear drum supports (rollers) is bad. A quiet thumping is almost always present as the weld in the drum comes in contact with the drum supports. A binding support will squeal, and the thumping could be worse at that time. After running the dryer until the noises are present, once disassembled, you can tell if a support is bunding or rolling normally by spinning it by hand. The same goes for the idler pulley. Make sure power is disconnected from the unit befor attempting any repairs.
While the unit is disassembled for repair, make sure your your old cat is not inside.
