Here is a tech sheet
And last but not least a service manual
First try rotating the drum by hand, should rotate fairly easily.
Could be the thermal fuse in the motor circuit (on the blower), the belt switch or the control board.
If it is the fuse be sure to clean and check the vent system and the blower wheel.
Using a meter is preferred but you can check the fuse by jiggery pokery.
Unplug the unit, short the wires to the fuse together, tape them up so they cannot short to the frame, plug the unit in and give it a try. If blown replace it ASAP as it is a safety device.
