Imagine that my MV sits on the counter, about where the leather bag
is in this shot:

I have never had an issue with a microwave walking or sliding from where
it was placed. Nor has the customer had a complaint of their microwave
moving in the 25 years that they have lived in this house.



I have a short piece 2 x 4 between the back of the MV and the
backsplash to keep the
MV near the front of the counter. Without it, the MV slides backwards
with use and ends
up too deep to be convenient. That extra 3 1/2" forward makes a big
difference.

Will backward movement be an issue with the cubby you built?


No. And there is no movement. The microwave opening is already there.
I am only dressing up up the cabinet opening so that it does not look
like a cabinet missing it's doors.

Can the microwaves easily replaced with a different size? Microwaves
aren't exactly the most reliable appliances and come in all sorts of
non-standard sizes.


Absolutely, I am only making the opening 1.25" narrower and shorter.
The opening is 24.5" x 18".

With opening smaller than the front (if I understand you), I'd worry
about heat. How are you cooling the microwave?


The microwave is about 1/3 the volume of the cuby. The cuby is huge
compared to the size of the microwave.

With that aside. A built in oven has less air gap and those run for
longer periods of time.

They have a lot more insulation in them and the electronics are
designed to be constrained. Microwaves are designed for their
particular use. Built-ins are not the same as counter models.

Regardless, there is more heat cast off from an oven than a stand alone
microwave. Manufacturers sell adapter kits to completely enclose stand
alone units. 20 + years with our old one and there was no issue of
heat. The microwave does not get hot like an oven, only the food gets
hot and then the food has a big air gap between it and the inside of the
microwave. Our counter top microwave never got hot on the outside.
There was only moderately warm air being exhausted from the unit.

Uh...yeah...I'm pretty sure that most of know how a microwave works by now. ;-)

We were indeed talking about that "moderately warm air" that you speak of.

I do believe that our point was that capturing even that "moderately warm air",
which I'm used to venting to an open room, would subject the device to higher
temperatures than it was designed for.

If you're happy, we're happy. Really.
