    I shut the door prior to use on my Whirlpool MH7140XFQ microwave. Immediately all power to the unit went out....no lights, time, beeps, etc. I thought I tripped the GFI plug in the kitchen. I plugged another appliance into the same plug and it worked ok. Seems like I blew something internal. Any suggestions?

Check the internal fuse. Unplug it, unscrew and take off the cover, the fuse should be easily found in the back by the power cord. It looks like a regular fuse but is white instead of clear glass because microwave fuses are special. You'll have to measure it with a meter as a result and be sure to replace it with the same kind. (try finding them at radio shack) Hopefully there isn't something more serious also.
Hope ya fix it!

I have a whirlpool undercounter model # MH3184XPS-2 an has no power


On this model, this is usually a blown fuse or thermostat.

This model has three fuses, a 20A, a 4A, and a .25A and three cavity thermostats.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

mini_manual_behind_grille_small.jpgdee77f7.jpgAt our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Accessing the cavity thermostats for testing and possible replacement will require you to remove the oven from the wall.

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

If for some reason you don't still have yours, you can download Whirlpool owner's manuals and installation instructions here.

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

If none of the fuses or thermostats are blown, then the problem is probably on your control circuit board, which is especially common if you recently had trouble with your cooktop lights or exhaust fans.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid with a one year guarantee.

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

Microwave stopped working, and its not very old. I wanted to know if it was the fues? How to replace it. 2008 i think LMV1680st


First of all, here is the main ONLINE SUPPORT page for your model:

http://www.lg.com/us/appliances/microwave-ovens/LG-over-the-range-microwave-LMV1680ST.jsp


You can download the owner's manual from the support site if you want, just look under the SUPPORT tab.

And here is a direct link to the Online Parts List and Service diagrams for that model:

http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5520022


To view the Support Page or the service diagrams just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the information at the website indicated and the contents of the Owner's Manual.

You may need ADOBE READER installed on your computer to read PDF documents like the owner's manual.
You can download this free at WWW.ADOBE.COM if necessary.
Click on the DOWNLOAD ADOBE READER button on right side of the ADOBE home page when you get there, the follow the onscreen instructions to install the software on your computer.

I will assume you have checked the house's main circuit panel for any tripped brealers and tested the electrical wall outlet for a good power supply.

Hopefully the problem is just a blown main fuse inside the microwave. In order to access and check this you will have to disconnect the power cord and then remove the oven from the wall. Then remove the case in order to access the electrical parts inside.

Here is a diagram of the fuse location once you have the unit disassembled:

http://www.appliancepartspros.com/partsearch/frame_diagram.aspx?diagram_id=28700124&pkw_=basket&model_id=5520022&NewWindow=1

The fuse is item number 5001 on the diagram and parts list.

Here is a picture of the main fuse on that model:

http://www.appliancepartspros.com/part_details.aspx?part_id=4440371

Just replace the fuse with an exact match and reassemble. If you tested the old fuse and it was still good, then you may be dealing with a more complicated and expensive fix possibly involving the control panel circuit board. At that point you may want to consider seeking additional assistance or just getting a new oven.

Thank you very much and good luck.

Joe.

I have a whirlpool model MH7140XFQ and we got a guy to come and look at it and he said the Mag. tube and the circuit bars were broken. Which would be more expensive to change the broken things or just...


He is referring to the magnatron tube which is the heart of the microwave. Probably more expense than you would want to put in to it.I would recommend replacement unless it is a high end model. Hope this helps

Fuse location on wall mounted Whirlpool MH7140XFQ


The fuse is in a holder located behind the control panel assembly.

At our site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

There should also be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

If you don't find yours, you can download it here.

If the oven is dead, it may also be a bad magnetron thermostat or oven cavity thermostat.

The first one can probably be accessed through the opening behind the control panel, but the oven cavity thermostat cam only be accessed by removing the oven from the wall, then removing the outer cover.

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

Feel free to contact me directly (and please remind me of your full model number) for more information & help.
