Dryer does not start ,only if you start sinning by

Maybe a belt or the start cap. The click is probably a relay switch. Will the drum turn by hand? Turn it on, spin the drum and close the door while its still spinning. If it starts then its the start capacitor on your motor. Most electric motors need extra juice to start. A capacitor is like a battery and can go bad after a while. It looks like a battery and should be mounted on or right next to the motor.
As it if you can fix this... that depends on you. Have you worked on dryers before? Do you know how to remove the panel from around the door with a putty knife?

Dryer will not spin, but can you hear the motor start when the button is pushed? If you hear the motor then the belt is probably broken. If you cannot hear the motor, then open the lid and check to see if there is a belt in place. A second cause for not dryers spinning are misaligned door switches. Shut the door and if it does not spin. Carefully hold the door switch closed by hand and see if does spin (for a second). This test will show that the door switch is working, but that the door is not closing the switch and that is it probably misaligned.

I need more info about the dryer. Does you dryer make any noise when the start button is pressed, if you can hear the motor turning then more than likely your belt is either after slipping off the drum or breaking. you should be able to access the belt either by the back of the macine or the top to see if the belt is broke or just after slipping. Another problem it could be is that the capacitor in your dryer could have blown. To test this you press start, open the door of the machine, spin the drum by hand and close the door before the drum comes to a stop, if the drum continues to rotate after you close the door then you know it is the capacitor that is blown, this needs to be replaced either by an electrician or a specialist as it is possibe to connect the capacitor wrong and the result would be the capacitor exploding damaging your hand. Always plug out the machine before opening the top or back of the machine.

Yes there is a start capacitor on this model, it is usually located at the rear right of the inside of the cabinet, so you will need to gain access to the inside of the dryer.

the buzzing noise is the motor trying to start try a test leave the door open with one hand press the door switch with other hand spin the drum at the same time have someone press the start button if your dryer starts then and when it is cool it is the motor replace the motor

if the door is not tight as in you can move it slightly when its closed,the door strike and door catch need replacing and can be done without dryer disassembly at the front door,open the dryer door and in the lower right hand corner theres a small plunger switch push this in with your finger you will hear a click,then start dryer with door open being careful,this test will rule out switch problem,then just replace door parts

ok open the dryer door look for a button inside where door shuts against hold that button down with other hand spin the dryer have some one push start button let it run for a sec then shut door and it should start

Since you stated that the heating element is heating up I believe it rules out the thermal switches.
When you push the start button does it make the motor make any noise? Maybe hear the motor humming? Two things to check for are Broken Belt or Bad Motor:
This requires common sense and since you are going to be bypassing the safety features you need be CAREFUL.

First, with door open, manually press in door switch to by-pass door safety, then press "start", try to manually start the dryer by spinning the drum by hand, If you hear the motor humming but it does not start spinning on it's own; most likely it is a broken belt which can be changed without much difficulty for less than $15 bucks. NOW if it then continues to spin on it's own GET YOUR HAND OUT OF THERE and close the door; you have a bad motor and even though it started it needs to be replaced. A motor for that is available for just under $100 bucks and is not to bad to replace, I would recommend replacing the belt at the same time since you will be in there. Good Luck!

You most likely have a bad motor. Try to spin the dryer drum by hand with the door open, door swich held or taped down, and while pressing start. This will likely get the motor going. If this works try closing the door and starting it again. If it works now the motor may have just had a hard time starting do to it's position or the drum's postition. If it only works when you help it out manually you have a bad motor or maybe a sticky drum/jammed belt/etc. Good luck!
