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.

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 model number) for more information & help.

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

GE Spacemaker XL - fan stopped working, light will come on and timer will count down.


either the magnatron fried , or the fuse fried... either way the microwve has to be taken down and opened up.
If you have the serial number , GE will send you a replacement magnatron (but will not service the unit for you).
contact GE and they will take care of you... the magnatrons are warranted for like 10 years....

My microwave GE model # JVM1440WH04 spacemaker has no heat coming out of it. My husband heated microwave lasagna in it last, everything works except for the heat, any solutions?


Push the microwave door tightly closed. The computer will not start cooking until the door is closed for safety reasons. Some models of microwave will give a warning on the screen if the door is open.
2

Ensure you have programmed a heat setting, entered a cooking time and pressed the "Start" button on the microwave's keypad. Check that the microwave is not set to "Defrost" mode.
3

Unplug the microwave and wait for one minute. This measure will reset the microwave's internal computer if it has frozen or scrambled. Plug the microwave back in and try again.
4

Ensure the keypad lock mode is inactive. Most microwave ovens have a lockout feature that prevents children from starting the microwave while unsupervised. Lockout mode is usually deactivated by holding down the button that bears a padlock symbol

I have a GE Spacesmaker model #JVM1440BH04 that came on by itself and can't be shut off unless the door is opened. It does not seem to be cooking since nothing heats up unless the cook start buttons are...


The problem is in one of the door switches, "it is defective" this is a highly dangerous situation and should be checked immediately, the microwave oven should unplugged until a appliance repairman looks at it.

GE Spacemaker microwave oven - Sensor error


Hello :

Many models of the GE microwave have sensors that can detect humidity from the foods you are cooking. This allows the microwave to make adjustments to the power levels used to cook your food. If "Sensor Error" appears, you should either press "Clear" to cancel the mode or leave the food in the appliance longer to give the microwave more time to detect the food.

Press "Time Cook" to manually enter the time if you receive an error message when trying to use the "Sensor Reheat" mode of your GE microwave. The error message may be caused by the food item being too large or too small to detect
..


good luck .

please rate !

GE Spacemaker Model JVM1860CD002 The oven comes on all by itself, starts in the express cook mode. This could be dangerous Rob


Beelow statmwent is refering to you appliance manual with also contains the wiring diagram. I woudl speculate that the clock/ timer wil turn out to be the problem since you said that you cannot set it. 
 
Microwaves: Inside the actual case. It is not consumer accessible. Over-the-range models have the manual behind the grille or control panel
