My microwave just stopped working. It still turns on but when I type in the cook time, it starts but doesn't heat up the food at all. I checked the power setting and it is on high and I've also tried leaving it unplugged and then plugging it back in. Nothing seems to work. It's only a year old.

It seems likely that the cyclotron has failed. If it is under warrantee then I suggest you return it to the place you bought it from to get it repaired. If it is out of warrantee, then you need to decide if the cost of repair is worth it, or whether you just buy another one.

SOURCE: Microwave does not heat food placed in the center of the turntable. Leaves a cold spot in the middle of the food.

This is normal. That's why I always recommend to my customers that the food be placed slightly off-center on the turntable. An analogy I refer to is stirring paint: If you stir paint with a stick by simply rotating the stick in the center of the can, it's far less effective than pulling the stick around an imaginary circle halfway bewteen the center and the edge.

SOURCE: GEJE2160 Stop Working

It probably blew the main power fuse in side the oven. This may have happen because of a failure in the microwave or a line voltage surge or what ever. Repalce the fuse and see if it work. be sure to unplug it before doing this, If this does not fix it then you have a failure in the oven some were.
good luck

SOURCE: Shuts itself off mid cooking cycle -- as if unplugged; then after 5 minutes or so turns itself back on as if it was just plugged in (forgetting all previous settings)

If you just put the fan blade back on, it will almost certainly fall off again.

The best bet is to slightly rough up the contact area of the shaft with sandpaper and use a little super glue to hold the blade assembly on the shaft, and let it set a few minutes before using it.

I always recommend that you use the hood vent exhaust fan when cooking on the stove top to keep heat, steam, and grease out of the controls.

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.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

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: microwave won't heat

Sorry my Clarification Request came out as a single blob of a paragraph.

That's not how I typed it. I never write that way!

So I've pasted it here, but as a solution.



Magnetrons generally should last about 2000 hours, but several factors can shorten that.

If it's not OVER ten years old (from the purchase date or the date on the tag inside the unit) then the magnetron is still under warranty.

From the owner's manual:

"For the second through the tenth year from the date of original purchase

"The magnetron tube, if the magnetron tube fails due to a defect in materials or workmanship. During this nine-year limited warranty, you will be responsible for any labor or in-home service costs.

"For the above limited warranty: To avoid any trip charges, you must take the microwave oven to a
General Electric Customer Care® servicer and pick it up following service. In-home service is also
available, but you must pay for the service technician’s travel costs to your home."


GE Customer Service is here, and you can verify the warranty status and find your nearest authorized servicer.

If you're sure the magnetron's bad, it's still under warranty, and you or a friend are handy, they will send you the magnetron to do it yourself. Call them at 888-239-6832.

Be persistent. You may have to speak with a supervisor.


It does sound like the magnetron overheated and the magnetron's thermostat opened until it cooled down.

An overheating magnetron can be due to:

  • operating oven without cover(s) in place
  • wrong magnetron installed in oven
  • an old or otherwise failing magnetron
  • cracked magnetron magnet
  • improper power line voltage (should be 110-125VAC)
  • foods low in moisture (popcorn & bacon, e.g. - add 1/2 cup of water in rear oven)
  • failed or inoperable cooling fan or hood vent exhaust fan
  • deteriorating foam weatherstripping seals in air ducts or on outside cover
  • blocked air vents (dust, animal nest debris, insufficient free air space behind & around oven, etc.)
  • clogged or greasy charcoal filter or grease filter
  • blocked duct in hood vent exhaust
Since yours is a counter top model, there are less of those factors to worry about.

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


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.

You can find helpful exploded view diagrams and order parts if needed by entering your full model number from the tag on the oven here.

Let us know what you find out or decide.

SOURCE: Microwave still runs but is not cooking food

Sounds like a bad magnetron, i would replace the magnetron, Capacitor and Diode at the mag assembly, to be honest it will cost you more to fix than a new one.............

New microwave stopped working after 15 seconds

Possibly the fuse / breaker is tripped, usually all outlets in one room share same breaker. Check breakers (or fuses) or try outlet in differnt room. If the outlet has power, (plugin a lamp to check) and the microwave still does not work, take it back to store for replacement or refund.
tip

DANGER WARNING! Potential Hazard if your microwave was working and now doesn't...

If you have this model microwave and it was working fine, then one day it stopped heating items placed inside there are a handful of different issues that could be the problem. In my case it was intermittent, over a period of a few days it would sometimes work (heat) and sometimes not. NO MATTER if this is what your's is doing or if it stopped heating all together. If you decide to let it dry out, or not use it for a while to see if it was a one time occurrence, or whatever the reason, the first time you put something in and probably for the next 10 times at least (this assumes it starts to work again), make sure you are right there with it while it is cooking. Don't assume you can put something in, go do something and come back when the timer is beeping. There is a chance (as this happened to me) that your food inside will CATCH FIRE! Normal food item placed inside, no metal, nothing different than the numerous times before when this had been cooked but when we smelled smoke we came running. Fortunately it started and finished inside the microwave but that's not a guarantee, it could spread. Play it safe. Never had a problem like this before and never heard of a microwave cooking something until it caught on fire (especially since the time entered for the cook was 30 seconds) but it did.

Sharp convection microwave oven model R1875F. It's cooking on the left side faster then the rest of the oven. It seems to burn on the left side and not cook in the middle.

see the next causes. God bless you
Diode The high voltage diode converts the A/C power output of the transformer to D/C, doubling the voltage to nearly 5,000 volts. This high voltage powers the magnetron which emits the energy that cooks the food. If the diode burns out, a lower A/C voltage reaches the magnetron, which is not sufficient to power the magnetron. When the diode fails it is often visibly burned out. If it appears to be good, it can be tested with a volt-Ohm meter capable of testing diodes. High voltage diodes frequently fail and are one of the most common points of failure in a microwave oven.

Door Switch If the microwave does not heat, one of the door switches might be defective. Microwave ovens normally have three door switches, if any of them fail the microwave does not turn on and does not heat. Check the switches for continuity with an Ohm meter.

Magnetron If the microwave oven doesn't heat the magnetron tube might have burned out. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. If the microwave oven is turned on when it is empty this can cause the magnetron to burn out. Once it is burned out it has to be replaced, it's not repairable.

High Voltage Capacitor If the microwave doesn't heat the high voltage capacitor might be defective. The high voltage capacitor works with the high voltage diode to convert the output of the transformer to DC voltage and to double the output voltage. If the capacitor is burned out the entire high voltage circuit stops working properly. The high voltage capacitor can be checked with a special VOM meter which has a capacitance testing capability. Be aware that the high voltage capacitor can retain a charge of more than 3,000 volts and can injure or kill a person if not handled properly. Only trained technicians should perform this type of testing.

High Voltage Transformer If the microwave does not heat, the high voltage transformer might be burned out. Microwave ovens produce a very high voltage in order to power the magnetron antenna, which emits the energy that cooks the food.

Thermal Fuse If the microwave doesn't heat the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.

Thermoprotector If the microwave doesn't heat the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown.

Main Control Board If the microwave doesn't heat the main control board may be defective. This is not common. When a microwave doesn't heat the problem is usually within the high voltage circuit; either the high voltage capacitor, diode, transformer or magnetron.

Not heating

Hello


Power Supply

Check whether there is a proper power supply. Look to see whether the cord is connected to a grounded 3-prong outlet and the cord is fully plugged in. If the electrical system is built-in and no power cord is visible, replace or reset the household fuse or circuit breaker.

Microwave Functions

Some basic microwave operational steps may affect whether the microwave is heating. Open and close the microwave door, as the unit will not function with the door open, and push "Stop/Clear" to cancel any previous settings, such as the timer, which do not heat the microwave oven.

Setting the Microwave

Once the power to the microwave has been reset, or verified as working, and the microwave is ready to run, select a new cook cycle and press "Start" to see if the microwave begins to run and cook food as expected. Allow the food to cook for the alloted time and then open the microwave door and check to see if the food has cooked or heated. Choose a longer cooking time and restart the microwave if food is heating but is cooking slowly.

Repair

If all efforts to troubleshoot the function and power to the microwave still do not get the appliance heating food as expected, there may be a repair issue that needs to be addressed. Contact professional technician for advice.
