Question about GE JVM1640 Microwave Oven

1 Answer

No heat - where is the diode

JVM1640AB002 mfg Feb 2000, kw= 1.58 SN DZ996205S This failed with a single buzz arcing noise (buuzzzzz-IT-ARC...SNAP! sound) similar to having a piece of metal arcing in the cooking area - but no arcing in the cooking area and no metal. It arced three times, once when it failed heating, twice after a restart, each time, no heat. Now no arcing or heat. No popped circuit breakers, just does not heat. Everything else works, display, fans, lights, turntable. I have tested the door switches, they function correctly. Reseated the connector on the magnetron, checked for broken insulation on wires, tapped the on board relays a few times Where can I get a schematic to locate the HV diode and check it before I locate a new magnetron? Or, is it even worth getting a new Magnetron? I mean, these are running for about $200-$300 retail. Thanks!

Samsong microvave does not heat, increase buzzing noise

You may have failing magnetron or shorted high voltage diode, but on some models, it is a failing capacitor on the controller.

We would need to know the full model number from the tag in the cooking cavity or elsewhere on the microwave, such as the door frame, controller frame, etc.

Please post a new help request with that and more detailed symptoms.

The magnetron is getting to hot and will eventually fail, especially when it is arcing, "a safety issue convern" the cause is the part mentioned above, or there is exposed metal on the inside cavity.

Sounds like a problem in the high voltage side. Need to check the diode and if good the voltage at the magnetron. Should be 3.5 volts across mag and 4500 dc volts at mag. If you do not have a meter to check replace both mag and diode aprox $150.00 from GE. Pat

Microwave won't heat, light ,clock works the microwave just won't heat the items in it.

when a microwave quits heating but every thing else is ok normally
investigate these 4 areas

Investigate these three areas if your microwave won't heat but you hear a loud buzzing or humming noise:
microwave_diode.jpg Power Diode

A diode is an electronic component that readily passes current in one direction only and blocks the flow of current in the opposing direction. If your microwave's diode has become defective, your microwave will not heat and you will hear a buzzing noise. Test the diode to determine if this is the cause of your problem. Replace it if it is defective.

picturena.gif High Voltage Capacitor

A capacitor is an electrical device which stores electricity. A defective capacitor may be why your microwave is not heating but you are hearing a buzzing or humming noise. The capacitor will have to be tested to determine if this is the cause of your problem. A defective capacitor will have to be replaced before your microwave will work again. Make sure you discharge the capacitor before you test it, though.

A defective magnetron is the third possible cause of why your microwave is not heating, but you can hear a buzzing noise. Test your microwave's magnetron. Replace it if it is defective.

Started arcing inside like it was on fire. It started to arc inside and making a loud noise. You could see big flashes coming from inside where the motor is. It did'nt last very long. I wont be buying...

When the micro starts arcing it is reasonably serious. One or more of the components are broken down. What needs to be done is firstly, "pull the plug out" The cover needs to be unscrewed and removed. You will then see the electrical components on the R.H.Side. There is a magnatron (creates the heat).and a capacitor (discharge voltage) and a HV diode. (DCcurrent to charge the cap). The magnatron needs to be replaced, and the HV diode. Please do not do it yourself as there are lethel voltages sitting there waiting for a wrong move. A technician needs to do the repairs as he has the appropriate tools to discharge the cap and do relative tests.

Panasonic Microwave NNSD277B 5yrs old makes noise after 20sec on (bUzzing and popping)and internal light flashes. Should be replaced or fixed ? what could be the problem?

You should have no arcing within the unit. Assuming you have adequate food/water in the cavity, it should not arc. You NEVER run the unit without something to be heated in it!!!

You might check the stirrer fan which is often in the roof of the unit to see if contamination might be in the area causing arcing. The electric fields in th area are very high and arcs can jump.

If the insulating window is charred or has charred grease, it should bbe replaced.

Microwave making loud buzzing sound when operated, sounds like something is about to pop.

could be several possible components at fault. how old is it ? does the unit heat ? if so, could be a hi voltage diode, or a hi voltage tranformer. (older frigidaire m'w's had trans. that would crackle and "arc" when bad) it is not the mag though, it wouldn't heat if so.

Microwave made loud popping sound and now does not heat.

Try this
Probably a high voltage diode popped because contaminated grease eventually built up and made a path for a high voltsge arc to occur.. To confirm,take the outer cover off the microwave and discharge the high voltage capacitor by shorting its terminals. Then pull the plug off the magnetron side and place it near the magnetron socket. Now turn the microwave on and push the connector on the magnetron with a chopstick or a long insulated screwdriver. If no arc when you do this this confirms a bad diode.

please rate my suggestion..

Kenmore 721.80524500 makes a buzzing, grinding noise

Your problem is due to the "magnetron" arcing to the wave guide within the microwave. Picture someone arc-welding stuff together inside the microwave casing, that's essentially what's happening. It is a fire hazard and you should stop using the microwave immediately. As far as I know, there isn't a recall on that particular model (though there was on another similar Kenmore/Whirlpool model) so if it's out of warranty, you're out of luck.

The magnatron is shorting and overloading the high voltage transformer which is complaining with a load noise. Worth fixing if you do it your self. Magnatrons cast about $40 wholesale. There are just a few varieties of them that fit almos all brands. Try
