Top 20 GE JVM1650 1000 Watts Microwave Oven - Page 5 Questions & Answers

replace it

it may have been the hi voltage at the magnetron,but the shut down is your heat thermocouple mounted on the magnetron side and when the mag overheats this thermocouple opens up and shuts off power to the mag to prevent overheating and fire

hello'

accorddind to the information pass across this means that your oven develop what is call partial contact this partial occur within the maize and the element i.e the wire which pass con rent from the ac to the microwave it self or the heat provider

these wire can be in two or three colour red and any other colour,
this occur when ever your microwave is about to heat up proper

what you need to do is that un scroll your oven to trace the wire connected to element to see which of the wire have been disconnected

after you being able to get which is loss from it position then look at who others are connected then replace the loss wire ti is position then your microwave will then work again has it's expected to

please note this while doing this make sure that your microwave is not connected to any form of power supply.

Good luck and thanks for using fixya.

Use a pair of needle nose pliers if you have them or wear a pair of leather gloves. Just grab the base and unscrew it.

There's a safety thermostat attached to the cooking cavity in most ovens to detect when something overheats. Once they operate they cut off power to the rest of the oven. These are usually non-resettable, and need to be replaced to repair the oven. If there wasn't any damage done to the interior of the oven you can see about having the repair made.

magnetron is leaking internally, do not use until magnetron is replaced. the mag creates interference with the control board and resets it

Find the breaker for it (a double for 220) and substitue a single breaker (for 110). This will leave one wire unused from the breaker box to the outlet. You'll have to change the outlet of course to accommodate a normal 110 plug. You can also skip the breaker part and just change the outlet and cap off 1 of the hot wires. Just make sure to kill the power and be safe!

Yes. There is an installation manual available for this model listed at managemylife.com. Just type in the model number under the "Manuals" link and the installation manual is available in .pdf (Adobe) format that you can download or print for FREE. Ductwork installation instructions for outside rear exhaust and outside top exhaust are listed. I hope this helps you.

Thanks for using FixYa and for the generous rating.

might just be magnetron and diode and thats not to terrible cost wise but if the smoke is real heavy the transformer may be burned as well and its not worth it then. mag & diode price with labor should only be $150-180 and add on an extra $120 for transformer

This is almost always due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

Details covering some previous models are in the GE bulletin here. Even if your model is not on the list, the same problem can occur.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.


NOISY MAGNETRON TEST (c) 2009 and posted by William E. Miller [email protected] (permission granted)
(I the poster am the copyright holder on this and hereby grant permission to this site keep this on its site)


(PLEASE do not be fooled into thinking that the procedure outlined at this link is a "fix". It should only be regarded as another test method to prove that you have a noisy magnetron which must be replaced.)

One way to test it is to do the following:

1. Unplug the microwave or turn off its breaker.
2. Open the door, then detach the control panel as shown in the video at http://www.microwavedisplay.com and swing it down, but without disconnecting the wires. If you have any trouble getting the grille off once the screws are removed, slide the hood vent grille to the left about 1/4", then then pull it forward. On some models there are L-shaped clips that fit into a slot to hold bottom of the vent.
3. Plug the microwave back in.
4. Make sure neither you nor anyone else reaches in behind the control panel. There will exposed high-voltage connections.
5. Put a few cups worth of water in a microwave-safe container and place it inside the microwave.
6. Shut the door.
7. Run the microwave for about 1 minute or so on full power. (Time Cook > 1 > 0 > 0 > Start, e.g.)
8. If it does not fail, try it several more times.
9. When the water boils, change the water and try again.

NOTE: If your model does not have a door handle, you will need to unplug the oven and reattach the control panel to be able to open the door.

If it still does not fail, I would recommend that you put it all back together and keep using it until it fails more consistently, then repeat this test.

If it keeps failing while the board is in the down position, you either have a very leaky magnetron or possibly another problem.

So you can then get a Ziploc bag and insert a flat piece of aluminum foil into the Ziploc and close it.

Then (with the power off) tape it over the circuit board as best you can, covering it as much as you can, making sure it does not get snagged or punctured.

Then try the oven again. Do not leave this test shield in place as a "fix". It is not safe.

While a microwave should never be left running unattended under any circumstances (as your owner's manual will tell you) it's even more important when one is exhibiting a failure or any odd behavior. So play it safe and stay with it while it's running!

If you or someone you know want to replace the magnetron yourself, you will need to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

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

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.



You can find links to helpful exploded view diagrams and part ordering help here. I recommend that you bookmark that link to your favorites.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

G.E. will send you the magnetron to do it yourself. Call them at 888-239-6832.

If it is not within the magnetron warranty, you can find helpful exploded view diagrams and order parts by entering your full model number here.

If it's an arcing sound, there may be grease or food particles on or behind the waveguide cover or in the area of the turntable motor.

Otherwise, it's likely to be a failing high voltage part:

- A sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound. Usually it will not heat is this is the case.

- A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but if this were the case, it would not heat.

- Sometimes a high voltage transformer will cause a loud hum and burning smell, too.

Please note that FixYa is not currently notifying us Experts when Clarification Requests are answered.

To allow us to help you effectively (at no charge), please post a NEW problem to FixYa, and please include your brand name and the full model number from the tag in or on the unit, and your specific symptoms.

Let us know which of the examples we gave seems to be closest to the sound you're experiencing.

probably blew the magnetron or high voltage transformer DONT test either unless u discharge the capacitor possible shock risk that unit is still live even unplugged.... i wanna telll you these days that micros are disposable items because the parts are gonna cost more than just to buy a new one plus if any arching occured that same problem is gonna occur again if it did work so basicallly that miro is kapout... hope this helped

replaced the unit.

That means your microwave is broken. Replace it or go on a service.

Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food?
A - 9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section.
Q - My microwave is running and sounds like it is working but will not heat up anything.
A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay.....
Q - The microwave display counts down and the inside light is on, but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.
There's no heat, but it buzzes loudly When the microwave won't heat, but you hear a loud buzz, you usually have a defective power diode, high-voltage capacitor, or magnetron. You can get required parts from www.repairclinic.com
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

Very easy - remove the lower plate on the bottom where the fan and lights are. 3 screws across the front, two on each side. This plate will come down, and the motor will be right there on the bottom of the cavity directly below the turntable coupling.

Go to www.microwaveglasstrays.com to find the motor.

March 2012 - GE does not support customers I have GE microwave with a failed Magnetron. It is emitting large sparks. Upon removing the magnetron I found that the sparks left residue where they are leaking from the cylindrical shaped piece on the end of the Magnetron. The Magnetron is under warranty. BUT GE WILL NOT HONOR THEIR WARRANTY AND SEND A MAGNETRON. GE HAS SENT OUT HUNDREDS OF MAGNETRONS TO CUSTOMERS - SEARCH ONLINE TO SEE THIS IS TRUE. I called GE PARTS, GE support and GE consumer relations department. They changed their policy two weeks ago and require a service technician to replace the part. THE COST IS $220 FOR THE REPAIR TECHNICIAN. Since I already removed the part the service technician would have to put in 3 screws and plug in the cable...FOR $220...I PAID $229 FOR THE MICROWAVE NEW!!!! DO NOT BUY GE. DO NOT BUY GENERAL ELECTRIC. GE DOES NOT SUPPORT IT'S WARRANTIES UNLESS YOU ARE WILLING TO PAY THE SAME AMOUNT THAT YOU PAID FOR THE PRODUCT!! Further research: GE Microwaves can spontaneously turn on and start a fire - see Consumer Reports web page here: http://www.consumerreports.org/content/cro/en/consumer-reports-magazine-march-2012/kitchen-fire-safety.html Further evidence GE retroactively changing their warranties: http://www.complaintsboard.com/complaints/ge-california-c197693.html

In all likelihood the mangnetron, the main heating "element" has failed, or perhaps even the Power Supply. You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.
