Pull on the belt...make sure it isn't stretched or broken.RemRemove the belt from the motor pulley and see if the motor will spin. Make sure you have the correct voltage. A 220v dryer requires 2 legs with 110v on each. If MOTOROLA Does Not Spin Check Voltage At motor. There should be a schematic inside the dryer (usually taped near the control panel) this will tell you if the motor is 110 or 220 v. If the motor has sufficient power but won't turn it is probably bad. ( note some 220v motors may have a start capacitor on it...this gives a boost to the electricity to get the motor started...if it goes bad the motor will not start..)
if you have a bad odor,pull off the vent line from the back and see if an animal is dead there,i've found dead birds,mice and a possum,in the blower wheel of some dryers,they get in from the outside hood,once they get into the vent line and slide down they can't climb back out or if the dryer is running the wheel does a job on them.also if you had some painting or staining done this also can make the dryer smell bad.this is going by what i've found when someone complains about an odor in the dryer.hope this helps,one more thing if the motor is overheating from the dryer not being cleaned out it could have like a shellac smell,you might have to take the dryer apart to see what's stinking or it could be something near the dryer,when the air is heated in the dryer it makes the smell worse but if you find waht is causing it and remove it the smell will go away,if it is from a dead animal you can wash down the area with soapy water,you don't want to use anything with a strong smell because your clothes will smell of that when the dryer heats up.what does it smell like?
unplug it,open the door,remove the two phillips screws that hold the door on and remove the other two on the other side,remove the door and pull the front panel off,just tilt the top of panel out,remove the four 5/16 inch screws that hold the front bulkhead on,then remove the top screws and the L bracket on top,remove the front bulkhead,pop off the metal wire holder on the right side and stick the bulkhead on the right side of the machine so you can remove the drum,lift the top panel up a few inches and slide out the drum,you'll see the mark on the drum from the old belt,put the belt on the drum ribs down against the drum,slide the drum back in,grab the belt,put it under the belt pulley,pull the pulley over to the motor and connect the belt on the motor shaft,put the dryer back together the same way you took it apart,you'll notice two short screws,they go into the holes that have a space around the hole,one goes in the bottom and then the other opposite side up top.hope this helps. http://www.youtube.com/watch?v=1eeJvqhHEYY
lg is a little more tricky to get apart, but ther are a few screws infint of the lint filter housing, as well as afew under the main lid."pop" the top by inserting a screwdirver into the clips located on either side perhaps 3 inches in or so.and then trher are a few phillips head screws that willl release the front panel,along the bottom right side is a few thermostats as well as a heater asssy, one of the thermostats have a red button protruding from betwwen the 2 wires, try pushing it in.it will reset the thermostat(its gotten too hot and "popped" for safety reasons...CHECK YOUR VENTING
