Question about GE Spacemaker JVM1640SJ Microwave Oven

1 Answer

Starts on its own right after it finished prior task.

When it starts on its own, it flashes 3.5 on the screen. Only way I can control it is by unplugging. Sometimes when it's re-plugged, it will do the request; sometimes it will do nothing.

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.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

If you would like to have us do this repair for you, we do that for $39.95 plus part costs.

But please note that for some models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame which comes with a new keypad.

In this case, you simply move your circuit board into the new frame.

Feel free to reply back or contact us directly with your full model number and we can tell you if yours is one of these models, and if so, we'll also give you the part number you need to order and a link to the best priced supplier.


At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

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

Rational selfcook oven say service 21


Service 21 refers to your humidity control valve (climavalve) did not make a full revolution in the time allotted (about 20 seconds). Pop open the front control panel by inserting and turning a 5mm allen key into the opening on the top of the oven. While the oven is at the home screen, flip the dip switch #1 on the back of the control board to the up or on position. On the screen you should now see a new icon resembling some tools, like a wrench and screwdriver, click this icon. Go to Basic Settings and scroll to the right once until you come to Basic Settings 1.2. It should say drain valve and flap with some numbers at the bottom. F-t is the number we want to focus on, take notice of the number there, usually 18-20 seconds. Push the start button to the right of flap, this time will change to 0 while the flap is re-initializing. After 20 seconds or so a new number should come up, if it doesn't or it is over 20 seconds by a lot then you need to replace your humidity control valve.

Additionally every time you turn on your oven the climavalve will cycle, checking to make sure it is working correctly, if you interrupt this cycle by powering off the oven you can simulate this error falsly, to rectify the error turn off the oven and turn it back on and wait a good minute for all of the self testing components to finish their checks.

Bosch hmt8656gb microwave doesn't always start


The problem is in the keypad control board and usually means it must be replaced to fix the problem, and the part alone is expensive.

Kitchenaid microwave model KHMS155L, starts randomly for 3 minutes with "PAN" flashing on display screen, than locks up with "F-2" message on display screen


"F2" means you have a shorting membrane keypad. The "Pan Heat" key is shorting.

On these models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

You can find helpful exploded view diagrams and order parts by entering your full model number* from the tag on the oven here.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you unplug the keypad (as per the photo below) and move the circuit board into your frame.

Some connectors may have a lock:

I have a Sharp Carousel microwave model R438DV 1200 watts. There is a small 5x7 screen on the right side wall. It now has a small hole and has char marks on it. When I use the unit a fire starts o


You have to replace that small screen which is called wave guide. If there is a sharp authorised service centre near to your place you can buy the part from them. Do not work the oven without replacing that part.

Hi, I have a Sharps R-23 AM 1900W microwave. When i use it, it starts the timer and counts down for a few seconds then stops and flashes with 'err 3' on the display. Can you help at all with...


Is that code actually "EE3"?

If so, that is called a Magnetron (1) and (2) failure, but it may not be the magnetron.

It may be any of number of things, form door switches to control board relays to the high voltage parts.

Methodical troubleshooting is needed, and we have the manual for similar models here.
