If this shows up twice, please excuse.

I'm trying to remove an old (but not push-button) GE Spacemaker
microwave/range-hood. I removed the 4 bolts holding it from the cabinet
above. However it will not budge. The top can be forced down a little
1/8", but it is still attached solidly. It will not slide out
horizontally, and I don't see any access panels apart from the guts of the
appliance itself. Suggestions?

Thanks.
