Dryer motor hums but doesn't spin

whenever i hear a humming sound in a dryer it's usually the motor or something caught in the blower wheel stopping the motor from spinning.open the door and see if you can spin the drum.if it spins by hand try this,open the door,push in the door switch with one hand,have someone push the start button while you hold in the door switch and spin the drum by hand helping it move,if it runs you have a bad motor,if it doesn't remove the bottom panel and see if the belt is broke and stuck in the motor but like i say usually it has something to do with the motor not spinning.hope this helps

When you get the hum, is the drum moving? It sounds like the motor is not turning. Can you spin the drum freely by hand? IF so, the belt may be broken. If not, you may have a bad motor. If you aren't handy, I'm afraid you're going to have to call appliance repair service, or think about getting a new or different dryer.

follow this steps and fix it. God bless you

Drive Motor

The dryer drive motor turns the drum and the blower wheel to exhaust the air. If the dryer stops the motor might be defective. If the dryer stops and the dryer motor makes a humming noise there might be something caught in the blower wheel, or the drum might be binding. Try removing the belt from the motor and checking the blower wheel for obstructions. Also try rotating the drum by hand with the belt off, it should rotate freely. If the drum doesn't turn freely, determine what is causing it to bind. The dryer motor can't be tested easily. If the drum turns freely and the blower wheel is clear, and yet the dryer still keeps stopping mid-cycle the motor may be defective. it will need to be replaced. It is not serviceable.

Drum Roller Axle

This dryer has drum support rollers. There will always be two supporting the rear of the drum, and on some models there may be two supporting the front of the drum. The rollers must spin freely to work properly. If the roller axles are worn out the rollers may not spin freely which can overload the motor and the dryer stops. If the dryer stops mid-cycle, remove the belt and spin the drum, it should spin freely. If not, check the rollers and roller shafts.

Drum Roller

This dryer has drum support rollers. There will always be two supporting the rear of the drum, and on some models there may be two supporting the front of the drum. The rollers must spin freely to work properly. If they are worn out or start binding the motor can get overloaded and the dryer stops. If the dryer stops mid-cycle, check to be sure the drum turns freely with the belt removed. If not, check the rollers. Do not lubricate the rollers or roller shaft, lubrication will attract lint and cause the roller bearings to wear out faster. If the rollers don't turn freely, replace them. The roller shaft can often be reused, unless it has worn down. Clean the shaft thoroughly before installing the new rollers.

Drum Slide, Glide, or Pad

The front of the dryer drum is supported by small pieces of plastic-like material. As the drum rotates, it slides on these plastic pieces. If the dryer stops mid-cycle, it may be that one or more of these plastic slides or glides has worn out. When they wear out the drum can start binding and put strain on the motor. The motor then shuts down and the dryer stops. Check the glides for wear and replace as needed.

Drum Bearing

The drum bearing supports the rear of the dryer drum. Over time this bearing will wear out and may cause several different problems. If the dryer stops during the cycle it may be that this drum bearing has worn out and is putting too much strain on the motor. If the belt is removed and the drum spins freely, the drum bearing is probably not worn out. If the drum bearing is worn out, there may be some grinding or squealing, and the drum will be hard to turn.

Dryness Control Board

The dryness control board shuts off the dryer when the clothes have reached the level of dryness selected by the user. If the dryer stops too early, the dryness control board might be defective. This is not very common and other possibilities should be checked first.

Sounds like drum is locked and motor is running and burned the belt. Try to spin drum by hand, Might check drum ends felt seals, Teflon bearing strips located on the bottom lip of front drum end for wear causing drag. Also check 2 drum support wheels to see if they spin freely, take the belt off motor pulley and spin drum by hand, if easier & motor runs drum is dragging. How is the spring on tensioner, does tensioner pulley spin free? Hope this helps locate the problem.

Check the belt for it may have come off or broke. The top must be removed to see

When the dryer will not spin the most common cause is a broken dryer belt.

If the dryer motor only hums when you press the Start button, the motor may be burned out. Here's how to test the dryer motor:

• Remove the belt.
  
  
• Check for obstructions in the blower fan housing.
  
  
• Manually rotate the shaft of the motor.
  
  

If the motor is very stiff, or impossible to rotate manually, and the blower fan housing is clear, you need to replace the motor.

If the motor rotates freely, run the motor momentarily with the belt removed and the blower in place. If the motor runs fine with the belt removed, there may be a problem with the idler pulley or the clothes drum. Try to rotate the drum by hand. If it is very difficult to move, correct any problem with the rollers or pulley, and then reassemble the dryer and try it again.

If the motor hums but doesn't rotate on its own even with the belt removed--yet you can turn it freely by hand--you usually need to replace the motor or the motor start capacitor.

Door switch Your dryer can't operate at all if the door switch is defective. It's inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. If it's defective, you need to replace it.

Since your dryer is "new" it is under warranty. I will explain the possible reasons why it will not spin. Then you can decide whether to make the warranty call or not.

If your dryer doesn't tumble, check these:

Belt
Motor
Door switch
Belt Dryers have a drive belt that turns the clothes drum. If the belt breaks, the drum stops rotating. Then you need to replace the belt, and often the idler pulley, because the pulley tends to wear out at the same time.

The drain pump is jammed or clogged up. Remove the filter cover and check for bobby pins, coins or bra wires. If clean, remove drum to pump hose from the pump and check for any foreign matter. Try to turn the pump impeller by hand. It should turn freely. If pump is not free, replace it.
