Great! It worked!
Have a LG condenser dryer (rc9011).
Error code: tE3
Symptom: Dryer stops with this error code after a couple minutes after start. You feel no heat at all..
Turned of the electricity
Unscrewed the back
Pushed the red small button.. (You'll hear a little "click"...)
Screwed the back cover back on
Turned on the electricity
...and tried again...
Wohoo!
