AR hope this reaches you before the paramedics arrive.

DO NOT GO TOUCHING THERMOSTATS, WIRES ETC. WHEN THE UNIT IS PLUGGED IN, IT RUNS ON 240 VOLTS WHICH CAN KILL !!!!!!!!

If the drum turns fairly easily by hand then the odds are that your motor is shot.

Here is the parts breakdown
Model LER8858EZ0

If you decide to fix it, UNPLUG IT, open it up and check rear rollers, belt idler, belt, drum seals, front glides etc. for slop and wear. Might as well do a full overhaul while you are in there.

If you decide that the motor is not too expensive, open the unit up before making a final decision just to see if it needs any other parts re: belt, rollers felt seals etc. These can add up quickly and there is no use ripping it apart and having to do it again in 6 months.

I do not recommend machines, if I did and it did not work out I 'd just make an enemy.

I would recommend:
Do not get fancy, the more stuff they put in the more stuff breaks.
Get a unit with rear support rollers not the center mount drum type.
Try to get one without electronics or the minimum amount of electronics. This may be difficult.
The old style but proven units which use thermostats instead of a thermistor with a board regulating the temperature are better. They cost less to fix and are easier to troubleshoot.
Make sure the wiring diagram comes with it. Ask to see it, if it is overly complicated walk away.
Try to finagle a service manual out of them, this also may be difficult, at minimum check on the internet to see if a parts breakdown is available on the manufacturers site.

The above are just my opinion, with a little luck others will read this post and add to or change these recommendations
