    I tried disconnecting & then reconnecting the magnetron in hope that I just had a bad connection. No such luck. I did see a larger in-line fuse near the magnetron. I'll try removing/replacing it first. If it still won't work then I may need some further insight regarding the capacitor &/or the diode bleeder. Thanks!

    How do you get to the magnetron tube so we can replace it? I have the new part but need help getting to the old part.

    i switched it on, then put in food to heat up. every sound was as the norm but when i openned the food was as cold as i put in. however, i noticed something unusual. there was a text reading 1s in the display area when you press the microwave button. i am just wondering what the 1s is actually doing there and just felt may be if that goes away my food will heat up. i have been trying but it is still there

Our GE jvm1870 is now over 4 yrs old, and had been working fine-- until recently when using, didn't heat anymore & also started making a crazy sound.

Am no electrician, so I called GE to help. Needed a new magnetron & some diode. Part was under a 10 yr warranty- the total cost for service call + labor was under $200. Not great, but beats buying a new microwave ($400-700) and having to install it.

Gosh, things seem to fall apart here when I take a few days off! *grin* On GE models, the most common "no heat" problems are a bad magnetron and a bad door switch. Since yours in only 3 years old, the magnetron is still under warranty. Your being inside the unit will void that warranty if detected. You should contact GE Customer Relations at 1-800-386-1215 (8-6 ET) to pursue warranty service. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your full model number (without the suffix) here: http://tinyurl.com/gv383

Continue with the solution. How do you test for whether it is the capacitor or the diode bleeder and how to replace the capacitor or the diodeand if this is feasible? cost and technical expertise.

Most likely, there is a fuse that is blown. there is a big fuse that is connected from the high voltage capacitor with the power transformer secondary section. if you a tech person, you can do it on your own if not..do not even think about it..it is dangerous to open a microwave oven..now if you changed the fuse and still not heating, either the capacitor or the diode bleeder need to be changed.. good luck

SOURCE: microwave runs but does not heat

With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.

The diode is a fairly cheap fix, and the mag will cost more.

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.

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.

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.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

http://www.gallawa.com/microtech/diode.html (if it's not shorted, it's probably okay)
http://www.gallawa.com/microtech/mag_test.html

That model number is not quite right. I'm going to assume it's JVM1740DMBB01.

(If that's not right, please check the tag inside the oven & reply back)

The membrane keypad is not available as a separate part, so you would have to order the control panel frame which comes with a new keypad.

In this case, you simply move your circuit board into the new frame.

The part number you need is WB07X11040 and you can find helpful exploded view diagrams and order this part here for $107.00 (compared to $164.75 from GE!)

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.

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

SOURCE: Problem with the GE Spacemaker (JVM1640SJ)

GE Will replace the magnetron for 9 years! Mine is a 2004 model with a one year warrently according to manual. HOWEVER they did say the magnatron was covered for nine years: call 888-239-6832. When I called they said thats all they get calls for and would send out in 3-5 days. NO CHARGE. I had to ask if there was coverage longer than a year on major parts and that's when they offered the info and I eventually was transferred to the right office. Saved $120 bucks on parts alone.

MICRO WAVE DOOR FOGS UP WHEN USING IS THAT NORMAL


A Microwave Oven works by heating water/moisture in food: if the boiling action (e.g. when boiling water) is greater than the oven exhaust fan can cope with, then the inside will steam up and fog the door glass: this is usually OK and 'normal' (this is actual the advise in cleaning up the interior of a microwave oven - steamy soapy water - see your manual).

Hope it helps.

Ge over range microwave runs but doesnt heat


If it does not heat and makes a loud buzzing sound, it usually means that the magnetron has failed. It the part that generatest the microwaves that heat the food. Replacement costs for magnetrons is almost as much as a new oven, so it rarely makes sense to fix. Sorry.

Kenmore microwave Model 72 8975590 (750 W) is taking longer to heat food. Takes 3.5 min to bring one cup water to boil, previously took 2,5 to 3 min. Does the element lose power over time?


I can adjust the power level so that circuitry seems to be ok. The longer water boil time could be partially due to the colder winter temperature of the inlet water. We'll just cook the food a bit longer as long as the magnetron is still working.

I tried to reheat food and didn't get any results. Could I have ruined it by turning it on without food?


well if you keep on running your microwave without any thing in it then yes! it burns out the magnatron
(thats the bit the heat come from) and when there burned out its a dust bin jod as there very pricy to by and its not a smart thing to do trying to fit a new one by yourself,, you stand a very good chance of just killing yourself first,,to test your microwave opn the door put inside a cup of cold water and turn on the microwave for 3 mins on full power, the water should be boiling by then,,,dont put anything in the hot water like milk or it could explode in your face! just tip it away

Crackling and popping sounds when you heat up food


thats normal water expanding and boiling off from the microwave boiling those tiny water pockets in food... sounds like popcorn sometimes.
Cover your food with a paper towel to avoid spatter on the ceiling of the microwave when this is happening.

Have GE JVM2050 over the range microwave, which stopped heating food and water since this morning. All other functions including light, key pad, clock, turntable work normal. The magnetron sound also


if everything works except the heating, it is most likely the mag tube is on its way out.........that is the most common reason for it not too cook.......since the microwave is a GE and it is 3.5 years old, i would say you are better off buying a new microwave, the mag tube starts at around $70.00 and up + the labor it costs too have a service person put it in........around another $60.00
