I have removed and taped the end of one wire from the top-most switch, then put the outer cover back on. The machine seems to be performing correctly except when done heating something, the "End" message does not go away just by opening the door; only by pressing Clear/Cancel. Maybe caused by removed wire?
With the cover back on, it does not appear to be perfectly closed around the front edge. Does it need taping or caulking? Is there any fear of radiation escaping from there or is only kept inside the unit? Thanks.
