Dryer runs for a few minutes then shuts off when u restart pushing in knob it will hum for a second then start and turn off again in a few minutes

If you hear a humming/clicking sound from motor area you more than likely have a bad motor.
Try this test out to see if u have weak windings or relay on motor.
Open the dryer door and turn by hand the drum while machine is on ON position. And you or someone else presses the door engagement switch in. If it starts up then u have bad windings

Another thing to check is the belt safety switch. With a multi meter.
Especially if u just replaced the belt. The belt safety switch is attached to the Tensioner and motor. IT LOOKS LIKE A DOOR SWITCH SOMEWHAT a little black pc of plastic with 2 prongs going into it. Sits at bottom of motor. Under the Tensioner. Attach meter clips to the 2 prongs on switch, Then when the little white push button is pressed in it should show continuity and none when released.

Lastly check ut push start button for continuity with a meter when pushed in the on position, it may have gone bad.

Open the dryer door and slowly rotate the dryer drum in a counterclockwise (CCW) direction. Rotate the drum 2-3 revolutions and then shut the door and see if it will start. If it continues to just hum and not start could indicate a voltage issue, motor issue or a friction issue. Open the door again and locate the door switch plunger in the upper or lower corner on the hinge side of the drum opening. Hold the plunger in while someone begins rotating the drum counterclockwise. While turning the drum counter clockwise and holding the door switch plunger inwards press the start button. If it starts, there is likely a friction problem or motor problem.

check and see if there is any thing in the dryer vent if not.open the door hold the door switch in like the door is shut.have your wife push the start switch in and turn the drum counterclock wise if it starts then the motor has gone bad if it hums still its still the motor.if it does start stop the dryer and try restarting several times sometimes they get a dead spot and it may work for years or may die tomorrow but these are a couple of things to try good luck

Hi,

There can be many reasons why your dryer will not start or turn...

The most common causes are the belt breaking or jumping off, or the motor going bad...

Here are a couple of tips that I wrote will help you to figure out why your dryer will not run...

ok can u turn the tumbler freely,
if no well there is something stuck in you blower like a sock or something
if the tumbler turns freely
keep the door open and hold the door switch
try pushing the start button
and tuning the tumbler, yes all three at the same time lol you may need a hand
try tuning the tumbler when you hear a hum
if it takes off bad news your start winding on the motor is bad or the capacitor depending on your model
if it does not turn, but the hum continues longer than 1-2 minutes it could be just a belt

sounds like your motor is overheating or going bad. sometimes lint built up around the motor can cause it to overheat. or the motor is dying.

when you try to start it again do you hear a humming comeing from the motor? can you jump start it by turning the drum while holding the start button? If you say yes to these questions you have a bad motor.

at leas 15 yrs old??? think it's done its time, its a great machine andwould reccomend replacing with a whirlpool/kenmore unit again.no tworth servicing in my opinion, average call here in new york 150-225, anbd those are for simple issues. id rather put money into new unit! bit be sure to check your venting id say 85% of dryers taking too long to dry are vent related issues

sounds like your motor is overheating, replace motor
