LG Dryer Problem

[daved]

New user here.  I have a problem with my LG DLE3777W electric dryer.  The display lights up, but nothing else happens.  I can here a switch in the upper left corner of the dryer when I push start.

I ran the diagnotics from the user manual.  This is what I get:

18:F1  /  UO1
236
17
17
236 - display goes off

I'm a novice with this kind of stuff, so I'm having difficulty understanding the manual.

thanks,

Dave

18:F1  > = you have model DLE3777W

If door not closed or bad switch = Drum motor will not operate. Display will flash at 0.5 second intervals

here is the service manual
check page 20 "Diagnostic Test"

Check it out dude, I bet that high limit mounted near the heater unit has blown. here is the part:http://www.repairclinic.com/SmartSearch/SSPartDetail.aspx?PartID=1268364&PPStack=1
I would blow out the dryer real good and check the plastic blower wheel for stripped out center post.
