Sean C Round Hill , VA August 15, 2015 Light bulb on interior of microwave was out Was pretty easy drop and replace, once i got past the "security" screws on the back of the microwave -- those torx looking screws with posts in the middle so you can't use any common tool to remove them. I "defeated" them with a dremel and a flat head screwdriver - notching a flat head slot in the head made them pretty easy to unscrew. Once i had the microwave open, the bulb was just a take out/put in spot. Pretty easy Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
