SOURCE: I have a built in Whirlpool Micro Wave oven that quit

if you open the cupboard door above the microwave you should see two or four screws/bolts holding the microwave up there. there should also be an electrical outlet up there where the microwave is plugged in. have at least two strong people. put some blankets on your stove top to protect it. unplug and remove the screws. it should be connected in back by a metal plate also. when the microwave is tilted down at a fourty five degree angle, you can give a little lift and it should pop off the plate in back. it is heavy. get a new one at sears or other appliance retail outlets. i dont recommend best buy. they really screwed me over so i dont send business their way.

SOURCE: maytag mmv5186aaw micro wave oven works but fails

There should 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.

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

Some questions to help you or someone you know troubleshoot it:

When you hit "Start" to microwave, do the inside light, cooling fan, and turntable all come on?

If not, then you probably have a bad door switch or door switch mount and should see these files:

http://www.microwavedisplay.com/safety.txt
http://www.microwavedisplay.com/disassembly.txt
http://www.microwavedisplay.com/doorsw.txt

If the inside light, cooling fan, and turntable are all coming on, then the problem is in the high voltage section, and then the next questions arise:

Any unusual noises? Is it louder or quieter than usual?

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.

If there's no unusual noise, it may just be a bad connection at the magnetron.

Here are some links you or someone you know can use (in order given) for high voltage section test help, but read the safety warnings first:


http://www.gallawa.com/microtech/diode.html
(if it is NOT shorted or burned looking, it's probably fine)


http://www.gallawa.com/microtech/mag_test.html
(continuity can be good even though mag is bad!)


http://www.gallawa.com/microtech/xformer.html

You can find links to helpful exploded view diagrams and part ordering help here.
I'd recommend that your bookmark this link to your favorites.



Accessing some parts may require you to pull the oven from the wall and remove the 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.


You can download owner's manuals and installation instructions for several brands (including Amana, Jenn-Air, Kitchenaid, Litton, Maytag, Roper, Tappan, Thermador and Whirlpool) here.

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

SOURCE: How many micro wave ovens will a 20 amp circuit support?

Please stick with me to the end ... some examples are for example only. There is no 1000 watt circuit per'ci.

This will not be possible overload, this is an accident waiting to jump on you, my friend

Install dedicated circuits for these ovens, my friend. It will cost you a little but will be better than having dissatisfied guests or talking to the zoning board or boarding house authority or (gasp) the fire inspector after the fire.

If you don't do this, when the breakers start flipping off, tenants will run extension cords to outlets that have power. A whole different and worse, problem!

Rule of thumb, lighting circuits should be designed to operate at 80%, for example, if you have 800 watts of lights on a 1000 watt circuit, you are at the max.

So, there is a possibility that your circuit for lights is already near max. Adding ovens is trouble. Don't forget the iPOds and cell phone chargers as well as lap top chargers, walkman chargers (older students), little TV's, DVD players, clock radio's, electric shavers, curling irons, steamers, popcorn makers, lava lamps and occasional electric heaters that will be snuck into the room.

What is a 1000 watt circuit ... good question. Ohms law comes into play here.

Volts X Amps = Watts
120 volts X 8.333 amps = 500 watts (a smoothie blender) 300 watts (slow cooker) 200 watts (hand mixer) = 1000 watts.


A 15 amp circuit will protect #14 wire and can carry about 1800 watts (a toaster (1500 watts), for example).

A 20 amp circuit will protect #12 wire and can carry about 2400 watts (i am using a big paint brush here. these numbers are pretty close but not exact and I am not a licensed electrician.)

When I wire, I aim lots lower, preferring to OVER build than to under build.

10 amp circuits are rare in modern homes. In general practice, if the need was to be protected at 10 amps, the wire used in the circuit would be #14 and it would be protected by the breaker at 10 amps. In this case, it is the device plugged into this 10 amp circuit that needs protection rather than the #14 wire (which would be technically oversized)

Another consideration for you is where is the water? If you have an outlet that is 5 feet from a water source (bath - kitchen - etc) it must be protected by a GFIC

A 30 amp circut will protect #10 wire --- but this is not a normal household circuit.

Maybe the best option is for you to have your electrician install a sub panel in the vicinity of use and run several 20 amp circuits from that location to the various rooms.

The answer to your question "How many (1150 watt)micro wave ovens will a 20 (amp circuit handle)" is TWO with nothing else on the line. The National Code requires dedicated circuits for micro wave ovens, BTW. A commercial application may have a different (more stringent) standard in your town.

Thanks for the opportunity to answer your question and thanks for your interest in FixYa.com

My micro wave reads that it is locked how do I unlock it. it is sears ultra wave


The "lock" function is nice if you have kids who like to push buttons. It disables the microwave oven to prevent it from running unnecessarily,
To disable the lock feature push the "STOP-CLEAR" button. Then press and hold the "START" button until 'locked' is no longer shown on the display panel.
To re-lock it, do the same thing until 'locked' appears on the display.
Have a nice day.

Try2910227 serial ywmh2205xvb-0 model arcing on the back corner were the rack sits.Is there a way to repair this seen is the unit was purchaced in June of 2011.


Yes, take the rack out and recycle it. I do not know why these micro-wave company put racks in the micro wave ovens. You get some insulation on the inside the micro flaking off next the rack.


The mega-tron tube is a very high energy transmitter. The energy will come out of the top inside the micro wave oven in a wave guide. Micro wave energy that generation by the tube is high frequency into Gega Hertz. You have a metal tray in side the micro wave acts like a big capacitor it stores energy in form of heat the next you know it look like Marconi is putting on a lighting display.



Leave the wire tie on a loft of bread and put in you micro wave oven to defrost. The next thing you might see is a load bread burning, instant toast. ----The use of micro wave were invented by the British before WWII. The mega tron tube generation very high frequency radio wave and these wave struck an object 100 miles away some of this beam energy would balance back to a receiver-----You have Radar.... I wish you and your family well being and be careful of micro wave ovens it can burn from inside out. GB you...stewbison

My Emerson microwave is about 2 years old. I washed it just like I do every week and the power went out on it.


you mean it want power up or want work when you press the star buttom?
1. check the fuse if no power.

2. If it doesn't work when closing the door after setting timer it is the micro switch that the metal lach hits when the door close.

3. unpluge the micro wave unscew the scews to the cover of the microwave remove the cover. up front by the door you will see the micro switch maybe (brown,black,white,red/white ) what ever color it is disconet it take it to the hardware store buy a new one and replace it,themreasemble your micro wave.

My microwave starts however food does not heat up.


Micro wave as the name suggests produces heat when the micro waves aimed at an object causes the water molecules inside the object to vibrate hence producing heat.The gadget responsible is the magnetron. If your magnetron is not receiving ht voltage or receiving but faulty, then your micro wave wont work please take precaution when opening micro wave due to high voltage caps that remain charged sometimes even when it is off.check the high voltage fuse/ diode and capacitor if they are fine and the step up trans former o.k then the only option is to replace the magnetron

The 'Start' button was pushed in too far, and it's now just sitting in there loosely. How do I fix this?


mcdevito75, You may have to replace the entire circut board containing all the micro wave ovens controls. Look for an small appliance repair shop in your area, or any place that sells microwave ovens for help.

Hotpoint microvave won't start rvm125j


Have same problem tech tested some components and gave up (i think) and just called it a circuit board problem. I have a service plan so the whole microwave is being replaced as it is apparently cheaper for the warranty company.
