ZE2160SF03 General Electric Microwave - Instructions

I just took off the cover, located the magnetron, replaced it and slapped everything back together and since then everything's been working pretty good.

Simply remove the cover after unplugging the Microwave. The light is attached to a bracket and unplugs from the electrical system and then pops out. Replace with the new bulb and bracket, reattach the electrical connection and replace the cover. Less than 15 minutes. Just need a special star screwdriver bit with a hole in the middle to remove and replace the screws holding the cover to the frame.

just placed it on the wheel

Remove bezel (4 Phillips sheet metal screws). Pull out unit and unplug from wall. Remove three sided steel cover (T15 or T20 safty bit required). Unclip double wire plug from base of lamp. Unclip and pull up on the lamp/bracket - discard. Push down new lamp/bracket, plug in wire socket to base of lamp/bracket. Replace steel cover and 4 'safety headed screws'. Lift unit, replug into wall socket. Insert into wall. Replace bezel and 4 Phillips sheet metal screws. Without the special "safety screw bit", this repair is impossible.
