Microwave Oven

I have a Quasar Microwave/Convection oven. I clicked on Hotpoint because Quasar was not listed in the brands available and clicking on “other” got to a dead end.
Anyway, it works fine but the interior light bulb has burned out and needs replacing. How do you get at it? The entire interior is stainless steel mesh with no indication which panel to remove (or how to do it. Should I take off the main back panel (in spite of grim warnings?)

I have since learned that our Quasar Mircrowave oven was actually made by Panasonic, if this helps anyone.

Also, I would like to cancel my two postings and start over, using the Panasonic brand name. How do you cancel or delete a posting?
