This accessory is designed to be used with select ranges and microwaves, models MHE14XK, TMH14XL, MH6140XK, MH6141XK, MH6150XH, MH6150XL, GH7155XH, GH7155XK, GH9115XE, and KHMC107E. Installing this accessory will require no disassembly or repair experience. Recommended Item: The Heavy Duty Degreaser Spray cuts through grease, oil andburned-on spills that may clog your microwave's filter.
