Replace Light Switch

I am trying to replace a light switch (part # 3 of diagram 5) [Freezer section replacement parts for General Electric ZISB42DSE Refrigerator | AppliancePartsPros.com](http://www.appliancepartspros.com/partsearch/model.aspx?model_id=231746&diagram_id=21839228#d21839228"]Fresh food section replacement parts for General Electric ZISB42DSE Refrigerator | AppliancePartsPros.com[/URL] on a GE ZISB42DSE but cannot figure out how to remove the grey colored grate (part #7925 of diagram 3) [URL="http://www.appliancepartspros.com/partsearch/model.aspx?model_id=231746&diagram_id=21839226#d21839226)

I can easily remove the 3 screws located at the top of the grate but it still won’t budge.

Any suggestions regarding how to remove this grate would be greatly appreciated.

Thanks.
