[COLOR="DarkRed"]I'm wondering if one of the wheels that the drum rests on may be frozen up, or if the bearing is bad. [/COLOR]
I cannot say without a model number.
Some units do not use rear support wheels.

The other things that got my attention in the videos is what he was saying about the sound. He said if it makes a humming sound, the belt may have come off or broken.[/COLOR]
Try the rotating of the drum. If it starts then you know for sure that the belt is OK.
A hum could be just a broken belt re: just the motor rotating.
When the motor is bad or has too much load the sound is more of a buzz.

If this happens, the idler pulley which is mounted to a microswitch will trip and not allow the motor to turn on..question is, would I still hear the humming or nothing at all?[/COLOR]
I cannot say if your unit has a belt switch, most units do not.
If it does then you will not have a hum as it kills power to the motor when the belt breaks.
[COLOR="DarkRed"]Then he said the other possibility is that the motor is bad.[/COLOR]
This is [probably the most common cause.
[COLOR="DarkRed"]Later on in the videos he pointed to another part called the motor circuit thermal fuse. He said if this is blown the motor will not come on. I can check that. He also said that if the thermal fuse is blown, I need to replace the cycling thermostat right beside it too, at the same time.[/COLOR]
I do not agree with some of the above but it really does not matter as a blown thermal fuse also kills power to the motor.
[COLOR="DarkRed"]I'm just not sure where I can get parts. I don't want to go through sears, but I don't know of any parts places. I guess I'm m going to have to call around and see where I can get them[/COLOR].
They sell parts at AppliancePartsPros.
I do recommend them for a couple reasons.
1. I have seen many comments from happy customers.
2. They sponsor this forum as a public service.
Note: I do not work for them.
You may want to try rotating the drum on a couple other units, then you will have a feel for what is normal. Also be sure to rotate it in the correct direction.
Before ordering anything I would recommend opening it up and checking the belt, the rear rollers if used, the rear bearing if used, the idler wheel and shaft, the drum seals, all internal seals, the front glides/supports etc.
If you decide to fix it you may as well give it an overhaul.
If it needs lots of parts it may not be worth fixing.
