The cabinets in the two most recent pictures were installed with a stove hood in mind, not a microwave. Even when proper planning has taken place initially a replacement microwave or stove may screw up the whole arrangement.
Best oven for a microwave installation has ALL the controls in front. 16 inches to the bottom of the microwave is probably a MINIMUM workable spacing.
My mind immediately goes to “flipper” when I see this. I’ve never understood why they all seem to do it but they do! Anything taller than a frying pan and you’re SOL.
. Interesting that Whirlpool doesn’t just come out and specify the clearance necessary… ya gotta do the math… which works out to needing 12.75 inches minimum! .
Wrong stove for that application. Stove should have controls on front edge for obvious safety reasons. Those cabinets were installed for a range hood ONLY!
