My dryer is makeing a loud humming sound , whats causing it

A number of issues could cause that.
Door switch contaminated.
Turntable motor contaminated.
Magnetron failed.
Capacitor failed.
Diode pack failed.
Pick one and investigate bearing in mind there are LETHAL voltages inside the case!!!

this is because of bearing worn out so lubricate the bearing or change the bearing then check the noice.

your motor is going bad.

Sounds like you may have a motor issue, they can get lint trapped inside, and it causes the motor to overheat, and eventually go out. You can remove the top, then the front, and see if thats the problem. Usually, once the motor starts making noise, its time to replace. Right now, the packings in the motor are cold, and once they heat up, they stop making noise, so it could last quite a while.

vibration,,there a screw missing some where

it sounds like a shorted heater element, this would also cause the heat to stay on at 110 volts which would make the clothes very hot since the element doesn't completely shut down. if it is a loud hum it could be a stuck motor switch but in this case the dryer usually won't start.
