There is an internal fuse, plus one or two thermostats or thermal cutouts.

You can probably find an exploded view by entering your FULL model number here: http://www.searspartsdirect.com

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

SOURCE: Sharp Microwave Model R-1830: No power

A microwave can be dead for many reasons.

It may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel or between the door switches.

If the fuse is good, it may be an open oven thermal cutout (TCO) on the top of the oven cavity / body or an open thermal fuse on or above the magnetron.

These should read closed (virtually zero) on a continuity check.

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 it went dead or when you plugged it in or opened or closed the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

You can usually find exploded views and order parts by entering your model number here at the Sears parts site but the best place to order Sharp parts is Tritronics.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

SOURCE: I have Whirlpool Microwave oven Model MH6110XEB-0

with any luck you have just poped the inline fuse,
if you remove the control board you should be able to see the tube fuse up by the fan motor
if not the whole thing will have to come down to reach it

SOURCE: LG Microwave LMVM2055ST Just stopped working!

It has probably had an overhesat problem and the repair is quite simple. First you must remove the cover. This will require the removal of alot of scres on top, bottom and rear of machine. Once done, looking down at the top of the microwave all the way to the left about half way from the front to the rear you will see a round senso with two black wires going to it. This issimilar to a fuse and when you remove it, you can test it with a continuity testor. Electric should flow through it with no resitance. If it does not, it must nbe replaced. It's about ten bucks.

I have a old jenn air wall oven and a old jenn air microwave mounted on top. it was a countertop model. when i removed it it was plugged into the top of the oven. would that be a 110 appliance outlet?


The Jenn Air microwave that is mounted above the oven in your unit is 110v 60Hz. The socket in the upper rear right corner of the oven is a 110v 6Hz socket and is where the microwave would be plugged in. If you are going to replace the microwave, you can plug it into that socket. If you would rather not use that socket, you will have to drill a hole in the side of the cabinet holding the over/microwave to get the power cord out.

Jennair JMV8208BCS No instructions in box


Hello. the installation of wall mounting bracket is not too difficult. you will need a drill, some bits, and a scrrewdriver. you will also need an electrical outlet at that spot to plug in the microwave.

Jennair makes a bracket kit for each microwave. Call any jennair dealer, have your model # handy and they will get you the bracket you need, also ask specifically for the instructions.

No power on Jenn-Air JMC 7000 ADB Microwave


I have a different Jenn-Air built in microwave & oven combination but I'm sure my solution will work for you as well.

My microwave was plugged into an outlet located on the top of the oven. This outlet has a "circuit breaker" that tripped while we were using the self cleaning feature on the oven. You just need to reset the breaker button right next to the wall oven outlet. Why it tripped is a mystery since the microwave was not in use at the time. Bad design.

Of course, getting to the reset button is your only challenge. You need to pull the microwave and oven out of the wall/cabinetry in order to get to it. The unit is heavy so you will need help. Or, call a certified repairman and they should be able to do this for you in 30 minutes or less so the service call should not run you more than @$85 if it is no longer under warranty.

I would also suggest you contact Jenn-Air to complain about this issue and seek reimbursement from them if necessary.
