Brokend,

Do you recall any fail codes in the display(F1,F2, etc.) ?

A quick test, open the dryer door and press in on the door switch plunger, listen for a "click"noise, do it several times.
then press in and hold the switch in and start the dryer, if it starts and runs, check and make sure the door is properly aligned and closing tight.

From there, we'd have to access the interior cabinet, and check for an open thermal fuse or control board(s) issue.

Thanks and good Luck,
:) :) :)
