Panasonic the Genius Prestige. Start microwave, sometimes a high pitch sound while microwave is running. Stop microwave and sound stops. Doesn't happen every time. Should I just get a new microwave?

On many models, you press "Stop / Reset" three times.

A hard reset may help: Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

If you don't have your owner's manual, you can probably download it (or one that's very close) here:

If that doesn't work, you can contact Panasonic UK at http://panasonic.co.uk/customer-Support/svc-dealer-locator.asp

H97, H98 or H99 mean that there's a problem with your inverter, magnetron, or digital programming circuit.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer.

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 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.

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

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.

During cooking,microwave stopped,no power.


Not good news; Panasonic uses a technologically superior power supply with higher efficiency but an overall worse record than those using a 'linear' supply with far fewer parts and a good track record of reliability.

The modern (switched mode) power supply places a lot more stress on components and requires more and higher quality parts than the old-style circuit.
