How to install a microwave oven on your own - Whirlpool MH7140XF Microwave Oven

Needs to be properly vented to outside the house. Only install a microwave that's designed for over-stove use in this space.

The wiring diagram for the microwave shows it is separate and distinct.
Usually slid-in counter top microwaves in this cubbyhole configuration have a trim piece surrounding & covering the front edges of the oven on all sides like a picture frame.
Normally you remove 4 or more screws in the trim frame, pull the frame off, then slide the oven out a little (there may be a locking tab on the cubbyhole's rails for safety) to unplug the cord, and then slide it out the rest of the way.

When a microwave is dead, the most common causes are a blown fuse, or a blown thermostat / thermal cutout / TCO on the magnetron or on top of the oven cavity.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

Accessing the oven cavity thermostat for testing and possible replacement will require you to remove the oven from the wall and take off the outer cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

Installation instructions should have come with it. If not, do a Google search online to find the installation manual. Generally there is a plate that installs on the wall and the microwave hooks into it and fastens to the cabinet above. Try this website for a manual. http://www.pdfoo.com/result-kenmore-microwave-installation.html

From page 14 of the installation instructions online here:

"Extend the house duct down to connect to
the exhaust adaptor.

"Seal exhaust duct joints using duct tape."

who's the maker of that microwave oven. That's a good place to begin this discussion.

eastlake...only if you think so. Most of these units use a submounting bracket set and then you hook your oven to it. This is a rather nasty installation...I've done several. If it's sturdy, you may just want to put in a filler piece.
