Found the needed replacement on ApplicancePartsPros.com and ordered it. New part arrived in 2 days. Old grill removed easily as it was no longer held on by (2) screws. Save the screws as the new part does not come with them. The new part is installed by aligning the bottom tabs to the corresponding slots in the microwave. While pressing down on the top of the grill roll the grill inward so that the top tabs slide under the frame and screw holes align. Replace the screws and you're done.
