Product review (5 stars): Works Great - Installation is not so obvious
Worked like a charm.  The challenge was to figure out how to put it in my GE Model JE2160SF02Manufactured July 2005.  The manual is quite deceptive, implying that you put in the new bulb from inside the oven.  Actually I could find no YouTube move that was relavent.  I had to slide back the case "cover" by removing I think 4 screws from the rear and sliding it off.  Then it is obvous where the bulb is and I needed a screwdriver to pop it off.  Very easy.

Of course this was after having to basically uninstall the microwave.  So budget yourself a half hour or so to change a silly bulb.  Not the best engineering design so such a mundane maintenance issue.  Instructions were ZERO.
