Question about GE JVM1650 1000 Watts Microwave Oven

1 Answer

Oven stops after a few seconds

Like other posts, the ge JVM 1650SH01 shuts down after cooking for a few seconds. It will also work with control panel at a 45 degree angle. I tried replacing control board but that did not work. Is this the magnetron issue I keep reading about? If so, does anyone know if GE will send the consumer the parts under warranty or does it have to be from a GE service man? I do not have a problem replacing it myself.Thanks for the help. The micowave was manufactured in Jan. 2005 and I think the magnetron is still under warranty.

Re: Oven stops after a few seconds

I like the information you give.
If the unit will work with the control Panel at a 45 degree angle it tells me you have a loose connection. The 45 degree angle puts enough pressure on the connection to keep it completed. With the Control Panel in it's normal position, the loose connection Heats and Opens the connection. After it cools connection is again made until it Heats up again. Remember Expansion, Contraction. I do not believe you have a Magnetron issue!! A Magnetron does not know if the Control Panel is at an angle.
Can you hear a slight "Click" when the unit shuts down? If so this is a relay opening. When you say you replaced the Control Board. Was this the Control Panel PC Board, or was it the Cook-Relay Control Board? A Door Switch not making solid contact can do this. Is your Door latching down solid? Check for loose connections, not open LOOSE.

GE spacemaker microwave turns off during cooking and display goes black

Step 1:

Door Switch

If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently


Step 2:

Main Control Board

If the microwave runs for a few seconds and stops there may be a short circuit in the main control board. Check other components first, these boards are often misdiagnosed.

Touchpad and Control Panel

If the microwave runs for a few seconds and stops the touchpad and control panel might be defective. There are several other components that can cause this problem, be sure to check any other components before replacing this board.


If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the microwave display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.

High Voltage Transformer

If the microwave runs for a few seconds and stops the high voltage transformer might have an intermittent short. This is not common. Check other components related to the microwave symptom first.


If the microwave runs for a few seconds and stops the thermostat might be defective. Watch our video on testing thermostat

My microwave oven shuts down when set at high a high cooking number. I must wait a while before it can used again. I have a GE spacemaker

It may be that your magnetron is overheating, which will trip the magnetron's thermostat, which will interrupt power until it cools down a few minutes later.

Or it may be a defective magnetron causing electrical interference that disrupts the control circuit.

In order to help you, we need your full model number and some further information.

So please post a NEW question, and please include your brand name and the full model number from the tag in or on the unit, as well as the answers to these questions:

- How long does it cook before it shuts down?

- When it shuts down, does it go completely dead, or does it just stop with the display still lit?

- When you try to cook, do the inside light, turntable, and internal cooling fan all come on?

- Is it making any unusual noise?

- Is it louder or quieter than usual?

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

Turntable and cooking power not working, everything else does.

You have a shorting membrane keypad.

If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and please do not leave it running unattended.

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.

No power to GE Spacemaker Microwave

I have model GE Microwave serial # JVM2070SK02. I start to cook something and it shuts off 5~10 seconds. Keyboard is still lit up, but no clock, fan, light and you cannot operate anything on the key pad. Unplug the unit and it resets. Sometimes it cooks, sometimes it doesn't? It is getting more frequent with the shutting down problem?

My ge microwave after running for about 3 to 4 minute it shuts down and will not start up again for 30 minutes model # TH903659B JVM 1650 JVM 1651 what is the problem thanks

If the fan comes on when you put the unit into a cook cycle and all sounds normal otherwise, you most likely have a bad magnetron tube. (Google "GE magnetron failure" and watch how many complaints and articles pop up). The tube overheats and trips the thermal relay causing the unit to shut off until it cools back down and comes on.
Very, very common problem on these models although GE will not admit it.

The microwave starts, then stops 2 seconds later

I tried a solution posted on another posting by placing the conductive plastic behind the control panel and it worked.
