Re: Appliance help
Jeff -- shouldn't be too much of a problem.
From your dimensions of the lower cutout indicates you had a 30 inch wall oven. Those dimensions you listed are the cutout measurements -- that's the dimensions you should be looking for not the actual dimensions of the appliance.
The body of the oven is smaller and fits into the cutout -- the face of the oven is larger so as to overlap the cutout in the cabinet to give a finished look.
The depth is also an important dimension.
For example -- I'm looking at a Bosch oven ( HBL3350UC ) that requires a cutout pretty much exactly what you have ( 28.5 x 28.25 ) --- the face of the oven ( 29.75 x 29.6 )will overlap the cutout opening by about an inch all around.
The same applies to built in microwave ovens.
There is another alternative with the microwave oven --- many manufacturers of microwave ovens have trim kits available to allow using a more conventional type microwave oven and insert into a cabinet to give you the finished look of a built in unit.
Hopefully this helps.
