Product review (5 stars): Perfect fit for my PVM1870SM1SS GE Profile Spacemaker microwave
Perfect fit for my PVM1870SM1SS GE Profile Spacemaker microwave.  Arrived quickly in perfect condition. Removed old grille by taking two screws out of the top and sliding to the left and pulling straight out. Installed new one by lining up the tabs with the slots, pushing straight in, sliding to the right, and reinstalling two screws in the top (not too tight).  My only gripe is that GE uses brittle plastic. The old grille cracked and broke apart only because of age.  Our microwave is 10 years old.
