Willene Dias, I am sure he can. It is a bit of a PITA but doable. You will need to remove all the screws and the wrap around the microwave, the outer cover is the metal wrap around, to access and replace the cavity lamp. Manufacturer part number is WB36X10131 and GE part number is AP2030108. The screwdriver needed is a Torx Tamper Proof Screwdriver and it should be size T20H. 56912B in the diagram shows the bulb and its location.Not an easy job, but definitely cheaper than paying GE $200. Hope this helps, good luck.
