Just saw this done yesterday.
How to open unit:
First, UNPLUG THE ELECTRICITY!!
There are two clips that hold the top to the front. Slide a putty knife into the seam between top and front about two inches from the corners, push the clips backwards and pop the top up.
Next, remove two screws on top of the front. Then open the dryer door and remove the two screws on the front, just below the opening. (BE CAREFULL!! THE DOOR IS GLASS AND THE FRONT WILL FALL IF NOT SUPPORTED!!)
The reset switch in built onto the thermostat. The thermostat is located in the bottom right hand front corner of the dryer. It is behind another component, so it is not easily seen. You may want to use a small mirror to see it. Or just gently feel around for a small round pushbutton.
Once you have reset the switch, close the unit by reversing the steps above.
I hope this helps!
