“Will the Frigidaire FGMV175QF OTR Microwave fit in my existing space? Outer dimensions of existing LG, (being replaced) are listed as 29 15/16" W x 16 7/16"H x 16 15/16" D. New FGMV175QF dimensions are listed as 29.94" W x 16.38" H x 16.19" D. However, cutout dimensions for new unit are listed as 30" W x 17" H x 14" D, which may be too much (unable to measure accurately with old unit still in place). Trying to be certain it will fit. Can this question be referred to Frigidaire or BestBuy installers? Thanks”
