GE JVM1650SH01 quits and asks to reset clock

After starting the microwave it may or may not complete the desired cook cycle or set time. It appears to reset and then asks to have to have the clock reset. I have replaced the front PCB with display and on board computer to no avail. I have noticed that just after starting there appears to be a relay click and it resets after that. Please HELP ME!!!

Re: GE JVM1650SH01 quits and asks to reset clock

Thanks musicmale -- i was gonna try the cpu board.. U saved me $$$

Just got off the phone with GE about my Jan 2005 model (not covered by the service bulletin above) They wouldn't cover the kit mentioned in the service bulletin (magnetron, stirrer and diode) but they did say the magnetron was under warranty ( even though the oven came with only 1 year warranty and its now 2 years old) They are sending me a new Magnetron for free but just in case I ordered a new Diode for $31 (WB27X1160) i din't order a new "stirrer" cuz mine is fine.
I'll let you all know if this works. in 3-5 business days.

Re: GE JVM1650SH01 quits and asks to reset clock

A repairman told me to unscrew the top cover on the front of the unit, remove the screws holiding the control panel and tilt it forward. I then started it and it ran fine, but as I tilted it back to the normal position, the display began to flash and the unit quit when it was back in place. GE paid for the parts and I paid about $48 in labor. The magnatron and diode were replaced. Two other shops had no clue what I was talking about, so I went with the guy who knew what the problem was.

Re: GE JVM1650SH01 quits and asks to reset clock

GE had a rash of "underperforming" magnetrons on these units. They would sometimes end up with stirrer damage, bad diodes, waveguide damage, and/or interference which "scrambles the brains" of the unit and makes them reset like they had been unplugged. The usual fix is to replace the magnetron, stirrer and high-voltage diode as a kit, and they used to cover this, but may not any more. Sometimes the unit gets run too long in a failing state and the waveguide and chassis of the oven get damaged. In that case, the oven would have to be replaced. To get the details and see if yours is affected, see this bulletin: Even if your exact unit is not on the list, you may have this problem. You can contact GE Customer Relations at 1-800-386-1215 and tell them your problem and they will put you in touch with a local authorized servicer.

My microwave turns completely off... Touch pad and lights inside... I have to wait 10 seconds to 10 minutes and then it turns back on and will ask if you want to set the clock. Sometimes it will let me...

Hi Ben,
This has got to be an intermittent power to the control PCB problem. The control board asking to set the clock means that the CPU has been reset by losing power. First, make sure that the problem is not the outlet by plugging in a small lamp or digital clock to see if it works intermittently or resets. Leave it plugged in for at least 24 hours.
(If using a lamp, put in a small 20 watt light bulb or CFL).
It could also be a bad connection to or at the fuse holder in the microwave oven. If all of the wiring and connections look good, it's most likely a bad connection on the control PCB probably around the transformer on the board. Be careful.......

I have a GE sensor microwave oven. Tried to heat food and sensor eror came on. Everything is running even the timer but no sound but the timer is running. Cant this be reset pls help


This is the solution to reset your microwave.

1 Pressing the clock button will display the time. You can also use this to know what time it is while cooking.

1. Set the clock by pressing the "Clock" button.

2. Turning the dial on the GE sensor microwave oven will display the hour of the day. Once you have found the correct hour, press the dial in.

3. Again, turn the dial to set the minutes of the day. When this is completed, you will need to press the dial in again on the GE sensor microwave oven.

4. When the time and minutes are set, turn the dial again for a.m. or p.m. Then you will need to press the dial in to save the settings.

5. Press the "Start" button to allow the clock to begin on the GE sensor microwave oven.

Our 2006 Samsung Microwave has suddenly ceased to heat anything. The clock works and the turn table goes around, but that's it. We had a couple of power outages just before this happened. Could it be...


Press the "Off/Clear' button to cancel anything on the display, and reset the microwave. This is a soft reset and will simply get you out of any program you have started. Press it when the cooking complete reminder appears on the display.
Perform a hard reset. Pull the plug out of the wall power supply, and wait a moment. Plug the GE microwave back into the wall power supply to reset any anomalies with the microwave's memory. You will need to reset the time of day if you perform a hard reset.
Reset the time of day. Press the "Clock" button, and turn the dial to set the hours. Press the dial to enter. Follow the same procedure for the minutes and a.m. or p.m. Press the "Start" button to start the clock.

GE Spacemaker Microwave Clock inop

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

Ge JVM1190 appears to be working but does not cook.

I spoke with a qualified microwave technician who advised me to buy a new microwave as the problem I was having indicated that the magnetron tube had blown. What a waste of time to ask for help from you.

Whirlpool(GH7145XF2-0) does not work occasionally

That's how it would sound if you were cooking on a power level less than full power.

If you enter the cooking time and hit Start, it should cook at full power by default and not cycle like you describe.

If you are using some sensor cook setting or automatic type cooking setting, it may cycle like that normally.

The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.

If you don't have your manual, you can download it free here. Check the lower right area to enter your model. number.
