I have a brand new GE Profile PVM 9125 microwave. From the first use it has made a clicking noise when you start any cook cycle. The noise only lasts for a second or so and then stops.

first, get your money back or get a replacement for no charge. now, unplug the oven for 15 minutes and try again. if no-go, then some device is faulty that only a tech can find

SOURCE: Ge Spacemaker microwave jvm240 wv Micro hood combo.

sounds to me like the magnatron has shorted out. i don't know of a way to test them unless you have some high dollar equipment. a continuity test prob wont tell you anything. what reading did you get on the cap when you tested it?

SOURCE: GE Profile Microwave will not heat

Unfortunately, there is no way to tell which part the microwave needs without opening it up for examination. There are a few parts that, if defective, would prevent the oven from heating.

• a high voltage transformer which passes energy to the magnetron
• a magnetron which converts high-voltage electric energy to microwave radiation
• a magnetron control circuit (usually with a microcontroller)

The problem you are having with your microwave is a common one. Not heating is a problem that can be caused by three things. I'll list the most common solution first, the magnetron that actually does the heating is what is making that noise and has gone bad. It is possible for you to also have a bad high voltage diode that has opened up, solution two, or solution three is the high voltage capacitor is not working properly as well. From my experience with microwaves I am positive that it is your magnetron that is bad. If you are not do it yourselfer you'll need to take it to a repair shop to replace. However, if you know how to use a screwdriver and can unplug a couple of wires with spade terminals on them, then you can take it off yourself, find another one and replace it the same way you took it off. The magnetron sits behind the control panel of your microwave but on top. It has cooling fins on it and has 2 terminals maybe three depending and make and model that plug into it. It has 4 screws that are easy to get to that actually holds it in place. If you do not have a good local source like an electronic parts supply place then you can find the right magnetron at www.mwoparts.com. Be sure you always unplug the microwave before touching or trying to take the he cover off and then when you take the magnetron off also.Good luck and God bless.

SOURCE: GE Eterna Microwave stops after a few seconds, must reset clock..

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 [email protected]

(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.

Sometimes they 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.
