Question about GE Spacemaker JVM1640SJ Microwave Oven

1 Answer

Fuse keeps blowing.

Please help me with this. I just replaced a dead fuse on a whirlpool microwave/over range. After I replaced it I noticed everyting works fine, fan, light, but when I turn on the microwave, it runs for 2-3 sec and the fuse blows again. Is there a short in the magnetron and will I need to replace it to avoid the fuse from blowing again?

    Thanx almostbob for your prompt reply.



    My microwave is a Whirlpool, model #YMH6140XFB2 and I have replaced the properly fuse (20 amp). Yet, the fuse keeps blowing. I don't know if the fuse is the problem since it is a no name brand. Hopwever, as I stated, the light turns on, fan turns on and display is on but only when I turn on the microwave it goes on for about 3 sec and then the fuse blows. I am thinking there is a short or malfunctioning mangetron. Does the magnetron need to be replaced?



    Again thanx almostbob for your advice.

Couple questions -
what else is on the circuit,
and what current does the oven need

there are whirlpool over-range models with
1200watts of microwave,
1500watts of convection power, a
60watt bulb and a
375watt fan

over 15amps -20amp circuit needed

if you inadvertantly replaced a higher current fuse with a 15amp fuse, it will blow every time.
the install guide http://www.whirlpool.com/assets/pdfs/product/ZINSTALL/8206589.pdf reccommends 20amp
not a solution, something to check,

Suddenly microwave stopped working


(would really like more info- digital number dead as well?)

(assuming completely dead) Could be a couple of things:
- blown fuses (inside, relatively easy to replace, std size avail at Raioshack) <-- most likely
- cut/loose power cord connection inside.
- (unlikely but worse case scenario) Door was closed crooked- one tong hit one door switch before the other- causing a short circuit internally that "self destructs" the microwave to prevent it ever operating with an open (or even crookedly ajar) door, irradiating any users. Typically it just blows the fuses, but if fuses blow immediately upon replacing and turning power on, then possibly one of the switches fused or melted internally, and needs to be replaced.

Whirlpool microwave gh7208xrb-3 fuse is good but the unit has no powernothing lights up at all it like it is dead.


Control board might be dead. Cost is quite high could run up to $200 or more. Many times I recommend just to replace it. Here's the dumb question, is power present at receptacle?, if over range microwave, in cabinet above microwave? Check for gfci receptacle tripped. Sometimes fuses appear good, always be sure to test with a meter.

My Whirlpool microwave MT6120XEB-0 keeps blowing the fuse. Inststalled new fuse and display and timer works. Cooking blows new fuse. It turns on, makes grinding sound and blows a new fuse within a second...


You almost certainly have a shorted high voltage capacitor.

See the safety warnings and help information here.

Chances are you will have to remove the oven from the wall to replace it.

Whirlpool Microwave (model WMH1164XVS-1 ) does not turn on


This could be a lot of things. IT might be a capacitor or diode. MY money is on the capacitor. Since it works for a minute before it quits.

Burnt food in my microwave and now it's dead.


The magnetron has more than likely failed, "heart of the system" the fact it burned the cookies in 15 seconds is a concern, suggesting magnetron was burning out.

Microwave Blowing Fuse. Fixed. After Day, Fuse Blows Again.


Hello there:
If you have all ready changed out the fuse and it has happned again i would first check to see that the fuse is the right one for the machine (i am sure that you did this but please recheck ) next i would look at the controle board as the next culprit it maay be failing expecially if there were any pops ar sparks that was noticed before the initial failure.
Also check to see if all of the wires by the board a re not loose or looked burned ar if there is any grease or anything like this around the area
And finally check to see if the plate is turning ok and not sticking cause this would cause the microwave to overload and it wil make every fuse you put in there fail after just a couple of uses ok
SO please try all of these things that i have explained to you
I hope this is very helpful for you.
Best regards Michael

Microwave went dead


Hi

If your microwave oven doesn't seem to work at all, check these: Fuses Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it.

Door switch If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work.


Please do rate the solution as FixYa and revert for further assistance.

Thanks

Microwave stopped working for no reason


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 thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

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 goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

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

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

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 your tech sheet, you can download it here.

If the cavity thermostat needs to be checked or replaced you'll need to pull the oven from the wall.

You can download Whirlpool owner's manuals and installation instructions here.

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

Fuse keep blowing up


You have a short in the system. removeing the fuse was not a good thing to do. The fuse in a microwave helps keep the system from an overload which can and I have seen this blow-up. The micro pump inside might have a dead short it,
