Question about GE Spacemaker JVM1640SJ Microwave Oven

GE JVM 1500 series microwave oven

The light is continously on in the box. I can hear a small noice like there is a small fan running. The numbers buttons are not responding and the microwave is not heating. It almost looks like it froze up. I disconnected power to it and turned it back on but it doesn't solve the problem. Any suggestions?

This is usually caused by either a bad door switch, a loose door switch mount, or occasionally a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Doorswitch or mount trouble can be caused by slamming the door or byopening the door while it's cooking without hitting the Stop pad first.

Thereare plastic mounts inside the microwave which hold the door switchesand onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimesit's a broken tab on the switch holder, allowing the switch to rotatejust out of position. This tabcan be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door orhandle as you try to start it. If it works or tries to work, then it'sa door switch mount or door alignment issue.

Ifyou or someone you know decide to look into it, we have criticalinformation on safety, disassembly and door switches at our site, andour link is at our listing here on FixYa:.

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

There may alsobe a "mini-manual" hidden inside the unit behind the control panel orhidden on the left side behind the grille, which is very helpful whentroubleshooting & testing.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

Microwave has power will not start


When you say it just hums, do you mean that it sounds like it is running but isn't heating? Or do you mean that the sound is different from when it normally runs? Is it quieter or noisier than normal? Do you hear the fan running or is that sound missing?
IF it sounds normal (or about the same as when it worked), but it's nust not heating, then it is probably a bad magnetron tube.

My microwave displays time etc, but does not turn on


That model number from the tag on your oven should be KCMS1555SS0, KCMS1555SS1, or KCMS1555SS2.

We would need more detailed information about what it's doing or not doing.

Does it respond to key presses?
Does the inside light come on when you open the door?
Can you enter the cooking time?
What happens when you press "Start"?
Does it run but not heat?
Does it count down but the inside light and fan do not come on?

Please post a new help request with the model number and detailed sympotms.

GE model JVM5503 (1980): light and exhaust fan work, but touch pad does not respond to pressing buttons and therefore no functions can be initiated.


That would be a problem with your "touch control" but it is no longer available.

The oven will have to be replaced.

Sounds like it had a good run.

1800 XL JVM1860BD - won't work


It sounds like your controller may be failing. Or it could be an electrical line problem. Any other electrical itmes giving you trouble? Has anyone measured the voltage level of your power line? It should be around 110-125 volts AC. If it's significantly lower or higher, you may have a bad connection in your breaker panel or in the wiring leading to the home.
