Microwave light burned out Jeffrey G. • Livermore, CA • August 04, 2014 My Repair & Advice The instructions on this site were helpful. The only snag was the screws on the back of the microwave a special 6 pointed "security" hex driver that accommodates a "nub"of metal in the center. OSH had these as a craftsman brand. there was a metal tab that had to be bent up to remove the bulb. replacement bulb was an exact replacement. Was this review helpful to you?
