I push the start button down, and it makes a humming noise, like its trying to turn on. The drum trys to turn. When I let go, it stops. It does that 2, maybe 3 times, then wont start at all. This morning I turned the dial to 'NO HEAT/FLUFF', and it started, stayed on even after I let go of the button. But it only lasted about 5 seconds. Then shut off. It has heat. I can smell it. Maybe thats because I cleaned some lint out from the back of it, and it got on one of the heating coils. Not sure what to do, if anyone has any advice, It would greatly be of help! Thanks for taking the time to read this.

As murderurfriends said odds are high that it needs a motor.

I would try turning the drum in the correct direction by hand, it should turn fairly easily. You may want to try this on a couple other dryers just to get a feel for it. This checks if perhaps you have a drum mounting problem and it is overloading the motor.

I would not order a motor till you have opened it up and checked things like the belt, rear support roller, front support, idler wheel etc. so you know what the total cost will be. You may as well give it a bit of an overhaul.

Also on the units often the blower wheel seizes onto the motor shaft and must be destroyed to get the motor out so do that first.
