    My microwave starts 3 min express by itself. All other functions seem normal. I believe the keyboard has a problem. The tape from the keyboard to the motherboard has an aluminum shield and has delaminated. I taped it back to gether without success. The motherboard had no burned spots or any unusual marks.

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

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.

Will not turn on - says F-3


F3 on a GE / Hotpoint microwave means you have a shorted 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 of course one should never leave a microwave unattended while cooking.

Please contact us with your full model number for free tips, advice, and an estimate.

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.

We have a GE Profile Spacemaker XL 1800. It began making a laboring noise and stopped cooking at the same time.


Sounds like the Magnatron or the HV Cap or diode is failed. Process of will show you which one. Very dangerous area to work in, not for the untrained. Eric

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.
