installing convection microwave

[acorn1028]

We are planning to purchase a new trailer w/o an oven-
I would like to be able to take out the installed microwave and put in a convection oven microwave combination. I am concerned about the safety. Does anyone have any experience with how hot a convection oven can get? Are there any other concerns I haven't thought of?

Our convection/microwave is mounted in a zero clearance location, meaning there's no space between the unit and the wall/cabinet. The internal temp of the oven will get to 400 degrees +, but the external surfaces stay cool. Ours works great with no problems since we took the time to learn how to use it.

The RV model units might be built differently than home units so they can be installed in enclosed cabinets.

We have never had a problem with this installation. It came from the factory this way.

A word of caution:
I have replaced two microwaves with convection types, one in my last motor home and one in my present unit.
I would highly recommend getting the "build-in kit" for whatever brand microwave/convection you get.
In convection mode, convection micros get much hotter than the standard ones. When it was first installed, the temp behind mine got up to 200 degrees F after 45 minutes in convection mode.
I did not get the build-in kit for my first installation and went through a lot of hassle getting the temp behind the unit down to a reasonable level. I ended up adding a grill above the microwave and an exhaust fan blowing air through the side of the motor home. This involved a lot of work and cutting through the side of the motor home.

The second time I got the kit and the job was much easier. There was additional sheet metal in the kit that formed ducts to move air in from the front and back out the front. It also came with decorative grills that make the installation look like it came from the factory with the unit already in place.

Note that there are some minimum clearances in back and on the sides that must be met. You should make sure the convection micro you buy is small enough to allow for the proper clearances.

The one I installed in my present motor home is a Sharp Carousel Grill 2 Convection R-820-BK (the BK stands for black, I think WT will denote a white one).
The dimensions are 20 1/2(w) X 12 1/8(h) X 19 3/4(d).

It was a little too deep but we (DW really) got a little creative and figured out how to trim the sheet metal on the build-in ducts so they fit behind the supplied grills. Also had to move a junction box on the back wall behind the microwave a few inches over.
It looks like a factory installation.

Lowes/Home Depot can get them for some units - the models they carry.

If you Google your brand and model number followed by "build in kit" , you should get other places to buy it. They aren't cheap but they add safety and maybe in your case make the unit last a lot longer.
