First unplug your dryer for over 24 hours before any attempt to fix / replace any parts.
Unscrew 2 screws at the top back of the dryer to remove the top panel. You then have to give it a hard nudge from the front (just above the timer & the other end) in order to remove the top panel.
Then unscrews the rest if you would like the side panel off.
Hope this helps
