    When you hit Start to
    cook, do the inside light and turntable come on?




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




    What is the model number?



    These answers will help
    me judge whether it's in the high voltage
    section (magnetron, transformer, or diode) or the control section
    (door switch or control board relay or connection).

If it is working but not heating, then test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.If turntable is not running check also the door switch.

The diodeand capacitors can be tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, evenif power is off.Capacitors can get discharged by shorting their two contacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

You can also order from MicrowaveSvc , they also provide parts.

Microwave timer works but will motor will not run/cook.


If everything works on the unit, but you do not receive any heat or possibly the turntable does not turn you have a faulty magnetron (controls heat) and a faulty motor (controls turntable). You would require service on the unit, if parts are available. Some microwaves are so small in cubic foot size, that manufacturer's do not have parts available for purchase/repairs.

GE microwave not heating, sensor error.


first suspect is the inverter board (power) and magnatron a distant second----in either case the part involved unless an expensive unit is pricey.

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.

Err3 ?


"ERR 3" means that the magnetron units have failed in the microwave. Food will not cook or heat up when the microwave is in use.

The magnetron is the main source of power and heating in a microwave. Magnets work inside a magnetron tube to create the heat and voltage needed to cook items.

Prevention/Solution: Bring the microwave back to the retailer or a repair shop for service. You may also consider purchasing a whole new microwave if the prices are cheap enough.

Good luck.

My JVM1653 stopped cooking, The turntable turns


your magnetron might be out. its what heats

One word for cooking bulb


Are you talking about the magnetron which heats the unit? Do you have no heat in the unit. If so, your best option is to just get a new unit as the cost of the magnetron is not worth replacing.

Quit heating


This is a sure sign that the Magnatron has burnt out and needs replaced ( This is what cooks the food!) Replace magnatron in oven unit and all should work well!

GH7145XFB-1 not heating properly


Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

Microwave does not heat.


The magnetron is the device that puts out the heat. In these units, that's the most common cause of a failure to heat. BUT - many of these units are subject to a campaign under which GE will replace the magnetron, stirrer and high voltage diode free. Check the bulletin to see if yours is covered: http://www.microwavedisplay.com/ge_mw_mag_kit_bulletin.jpg Even if yours is not covered by the bulletin, it may have coverage of the magnetron. If you have questions, call GE Customer Relations at 1-800-386-1215 (8-6 ET)

We own a GE Microwave jvm1653sh01


The first thing I would check would be the magnetron TCO (thermal cut-out). This is a little safety devise that protects the magnetron in the event of overheating. These can act up even without overheating. I believe the nuetral side of this TCO runs through the board, and therefore the flickering and shutdown. When the TCO cools, it resets. If it were the door switch, you would blow the fuse and wouldn't be able to set the time without changing the fuse. There are other cavity thermostats that could be the culprit but my quess is on the magnetron TCO. When working with microwaves always unplug the unit and discharge the capacitor. This is high voltage..Good Luck
