    Same problem except it will run for two seconds exactly and shut off.

    Microwave works, but it sounds like the fan is only running about half power. Then, after about 5 minutes of cooking, the power cuts off like it has been unplugged. After 10 minutes or so, the power comes back on and will work again for about another 5 minutes.

SOURCE: microwave cuts off after heating for about 3-4 minutes

There is a overtemperature device inside that is shuting you down until things cool off. Take the cover off and clean up everything as much as possible. Grease from the cooking can get all over everything inside and collect dust buildup enough to obstruct the airflow and cause overheting.

If the fan comes on when you put the unit into a cook cycle and all sounds normal otherwise, you most likely have a bad magnetron tube. (Google "GE magnetron failure" and watch how many complaints and articles pop up). The tube overheats and trips the thermal relay causing the unit to shut off until it cools back down and comes on.
Very, very common problem on these models although GE will not admit it.

  • Make sure that the microwave is plugged into a grounded outlet. It must be a 3-prong outlet.
  • Make sure the clock is set.
  • Check to see if a programming sequence was entered. Sometimes improper programming or a program sequence such as delay start can cause the touch panel to be non-responsive. Unplug microwave or turn off house circuit breaker for 30 seconds. Plug back in, or reset circuit breaker, and try reprogramming unit.
  • Check the house circuit breaker or fuse box. If the microwave is DEAD and there is no display and nothing works- the problem could be a blown fuse or tripped breaker.

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.

If that doesn't work, leave it unplugged for about 5 minutes.

Otherwise, this is almost always due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.


Details covering some previous models are in their bulletin here. Even if your model is not on the list, the same problem can occur.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

NOISY MAGNETRON TEST (c) 2009 William E. Miller prototech@usa.net

(PLEASE do not be fooled into thinking that the procedure outlined at this link is a "fix". It should only be regarded as another test method to prove that you have a noisy magnetron which must be replaced.)

One way to test it is to do the following:

1. Unplug the microwave or turn off its breaker.
2. Open the door, then detach the control panel as shown in the video at http://www.microwavedisplay.com and swing it down, but without disconnecting the wires. If you have any trouble getting the grille off once the screws are removed, slide the hood vent grille to the left about 1/4", then then pull it forward. On some models there are L-shaped clips that fit into a slot to hold bottom of the vent.
3. Plug the microwave back in.
4. Make sure neither you nor anyone else reaches in behind the control panel. There will exposed high-voltage connections.
5. Put a few cups worth of water in a microwave-safe container and place it inside the microwave.

6. Shut the door.
7. Run the microwave for about 1 minute or so on full power. (Time Cook > 1 > 0 > 0 > Start, e.g.)
8. If it does not fail, try it several more times.
9. When the water boils, change the water and try again.


NOTE:
If your model does not have a door handle, you will need to unplug the oven and reattach the control panel to be able to open the door.


If it still does not fail, I would recommend that you put it all back together and keep using it until it fails more consistently, then repeat this test.

If it keeps failing while the board is in the down position, you either have a very leaky magnetron or possibly another problem.

So you can then get a Ziploc bag and insert a flat piece of aluminum foil into the Ziploc and close it.

Then (with the power off) tape it over the circuit board as best you can, covering it as much as you can, making sure it does not get snagged or punctured.

Then try the oven again. Do not leave this test shield in place as a "fix". It is not safe.

While a microwave should never be left running unattended under any circumstances (as your owner's manual will tell you) it's even more important when one is exhibiting a failure or any odd behavior. So play it safe and stay with it while it's running!

If you or someone you know want to replace the magnetron yourself, you will need to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

G.E. will send you the magnetron to do it yourself. Call them at 888-239-6832.

Be persistent. You may have to speak with a supervisor.

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

GE microwave won't turn off


Just checked the GE website. Had the same problem with my 5 year old microwave. GE website says to close and open the door quickly three times. First time I did this it didn't work. Second time I closed the door with some significant force and reopened it more quickly. Worked. Unplugged the microwave, plugged it back in, still fine.

Ge spacemaker model # jvm16505ho1 won't stay running


I have the same problem. It was/is a wiring issue behind the key pad. I unplugged the microwave and took the vent and key pad covers off - heed all warnings. Using leather gloves and needle-noze pliers, I removed the wire ties and reposition the wires. I also checked the plastic connectors for looseness. It's currently working, but for how long who knows. Mine is 3+ years old. I will never by another GE product.

I suggest you don't tackle yourself as the capacitor can hold thousands of volts even w/ the unit unplugged. Be careful.

Demo Mode


Unplug the microwave for at least 3 minutes, then plug it back in, and BEFORE SETTING THE CLOCK, press and hold power level and start for three seconds. This should flash "demo mode off". Set the clock as normal. Enjoy!
