Question about GE Microwave Ovens

JE1860SB 001 model

Small flames and then flashes of light within seconds of trying to heat something. Had appliance rescue person out and he said it was the magnetron. We ordered and replaced the magnetron and the same thing is happening. What's up? I'd appreciate any help you can give me.
Thanks in advance,

    I am aware of the fact that metal objects do not belong in the microwave. I had a "glass" of coffee inside which is how I have been reheating coffee. Any other ideas?
    Thank you,

    Cleaning fixed the problem!!! I didn't realize the inside of the plate was dirty. Thank you very much!!!! I did have a repairman out and he diagnosed the problem as the magnetron and said it would be $427.00 to repair it. That's when I ordered the part online and replaced it myself for $110.00. As it turned out, I didn't even need that part!
    Thank you, thank you!

    It looks like there's lightning (arcing) inside my microwave

    When you see arcing inside your microwave, it's because of food or liquid left in the cavity or on the wave-guide cover:

    • If the wave guide has any burn spots, replace it and clean the unit well.

    • If the cavity has any burn spots, spot-sand it smooth and touch it up with microwave interior paint.

    Note… If there are any burn holes in the cavity, don't use the unit-seek help from a qualified appliance repair technician.

The magnetron can flash if there is metal inside the microwave

    Probably there is dirt or metal particles inside the ovenis. There should be a little square cover that rotects the magnetron from fats and food from getting on it, is called "the wave guide shield" this can also be dirty inside or damaged, make sure you clean up any fats where the shield fits, and if problems persist replace the cover that costs around $10.

    Always better having the job done by a repairman, if you recently had magnetron replaced by a repairman, and it did not fix it ask to have the cover replaced at part only cost.If it is under guaranty even better.

    I am glad you fixed, this is a common problem on microwave ovens.

Ge micro wave/ model# jvm1440bh01 manu 01 2005. All lights and turntable works,does not get hot. After it runs for a few seconds it changes to a lower and louder pitch. Tried to change power level and...

If the cabinet is intact and the door closes properly there is
absolutely no personal danger. Aside from the brain (timer,
temperature controls, etc.) there are four major components in the
cooking mechanism. They are:
1) step-up transformer
2) diode
3) storage capacitor
4) magnetron
The step up transformer supplies about 3000 volts ac which is
rectified to dc by the diode and stored in the capacitor. The
magnetron converts the high voltage dc to radio frequency energy in
the 3000 Mhz range which induces many small currents in the moist, and
conductive, food which causes internal heating by resistance.

Failure modes usually involve #2 or #4.
If the diode fails there is no heat at all and somtimes a loud hum or
If the magnetron fails, the heat is reduced, or absent, and again can
produce a loud hum.

Snapping results from the microwave energy exciting some conductive
particles that can be due to residues in the cooking cavity, or
breakdowns within the magnetron itself. If the cooking cavity is clean
and there are no loose metal objects within it, you problem is most
likely to be a failed magnetron.

These can be purchased new for about $50 but there are tons of usable
parts from discarded appliances. A local technician should be able to
replace this part with a used one for less than $50 total. They come
in about 3 or 4 variations (physical mounting screws, etc.) but can
often be altered to fit safely and effectively.

IF the its within warranty get it replaced, I personally recommend a tech to work on it.......

Good luck..................

Flame Sensor not available

We could look it up if we knew your full model number, but some of their budget models (like some made for Wal-Mart) are made with only turntable parts available.
Within the warranty period, the oven is to be returned to the dealer.
But a fire would not normally be covered under warranty unless the oven came on by itself when idle.
Otherwise, the thermostat / TCO has temperature markings on it, and a generic equivalent or very close type can be matched at a local appliance parts store.

Rival Microwave Model RGM41101 will not heat

If the lead and the plug are ok and the panel lights up, do not attempt any further repairs of inspection. A microwave is an extremely dangerous appliance and should only be serviced by qualified persons.

The magnetron may have overheated due to a failure of the internal cooling fan, blocked air vent in the back, or a clogged filter, if so equipped.

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.

There should also be a "mini-manual" hidden inside the unit behind the control panel or in an envelope on the inside of the cover, which is very helpful when troubleshooting, & testing.

Feel free to contact me directly (and please include your full model number from the tag in or on the unit) for a free estimate and free tips & do-it-yourself advice.

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

Not Heating. Fan, turntable, light working.

I would definitely suspect the door locking mechanism in this case. If it was the sensor it would start and then stop within a short time.

The starter switch should click if you have the door open and time it for 01.seconds and press start. So that is the secon component to think of.

My microwave is no longer putting out any heat

The problem could be caused:
top door micro-switch
Answer: First, make sure your microwave is plugged in and getting an ample supply of power. If the power is on, but it does not work check to make sure the door closes and aligns properly. Microwave door switches have metal terminals on the end that make contact with the door hook or latch. This completes the circuit which allows the microwave oven to run and without this contact the microwave will not operate. A simple misalignment might be breaking the circuit causing the microwave not to operate.
If you suspect that the thermal fuse has blown, call a professional appliance repair person. Even an unplugged microwave oven can kill or seriously injure someone. This is because there is a high energy capacitor inside the microwave oven case. If it is not discharged properly, you could be electrocuted.
If your microwave buzzes or hums but does not produce any heat, it could be a faulty defective diode, triode, high-voltage capacitor, or even a faulty magnetron. However, this problem usually means a bad means a bad magnetron, followed by a bad diode. Call a professional appliance repair person for assistance.
Warning: Microwave ovens are probably the most dangerous of consumer appliances to service due to the very high voltages (up to 5000 V) at potentially very high currents. If you have any doubts about your knowledge and abilities, replace the oven or have it professionally repaired.
