LG Dryer heats but won't tumble

[MedinaDad]

I have an 8 year old LG dryer and after a load of clothes it stops tumbling.  When we put a new load of wet clothes in and start it, we can hear it trying to turn but it won't.  If we don't shut it down it starts to smell like it is burning.

My questions are simple.  Any ideas on what the issue maybe and is it worth having it repaired or should I jump to a new one right away.

Either something is stuck in the blower or it has a bad motor.

Something stuck in the blower doesn't seem to make sense given that the drum rotates sometimes but not others.  Or am I missing something?

Sounds like you have a bad motor.  Try this.  Open the door, press and hold the door switch, press power switch on, press the start button.  If you hear the motor humming, turn the drum by hand.  If the drum motor begins to turn, replace the motor.
