Question about Jenn-Air JMC7000 Microwave Oven
I'm trying to find a replacement for a Jenn-Air microwave model M170B. It is a built-in "microwave over wall oven" unit. I called Jenn-Air and they told me I had to replace the whole unit. the oven is fine but the microwave has gotten old. Has anyone tried to replace this model microwave and what model did you use?
So it's dead? (No display, no inside lights, no beeps?)
A microwave can be dead for many reasons.
If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open. When it cools, it closes the circuit and allows power through again.
If it's random, it may be a bad connection, usually on the control board or fuse holder.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

First of all, what are the symptoms? Please reply back and I'll be happy to share my thoughts.
Many parts can be accessed without removing the oven from the wall by just removing the control panel.
You need to be sure the cord is unplugged, then you remove the vent grille that runs across the top.
Then you'll see a screw holding the control panel in place. Once that screw is out, you can lift out and out carefully to separate the control panel form the chassis.
If you pull any wires off the control panel, mark and/or photograph them first to be sure you get them ALL back in the right place.
There may also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

While they don't have their installation instructions online, the owner's manual is online here.

Bottom line is... Home warranty companies will do anything possible to wriggle out of paying for something. (Especially if it's American Home Shield).
I'd suggest offering to fax / email photos and the front cover of your owners manual. Your model is 100% considered a built in unit and they are lying to you and trying to cheat you if they say otherwise.
