H95, 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.

    Hopefully it was a glitch, fluke or spike, etc.

    But it may be a problem that is intermittent now (like a bad connection) and will a "hard" failure with time.

    This is a standard microwave rule anyway, but especially under these circumstances be sure not to leave it unattended while it's cooking.

    If it works for a week or so, you may be okay.

    Good luck!

My Panasonic NN-ST657W microwave has suddenly come up with an H97 code on display panel. Switches off after about 6 seconds before displaying this code. What has happened?


This oven is programmed with a self diagnostics failure code system which will help for troubleshooting, H97, H98 and H99 are the provided failure magnetron and inverter circuit problem areas. This section explains failure codes of H97, H98 and H99. H97, H98 and H99 appears in display window a short time after start key is pressed and there is no microwave oscillation.
There is not a lot the layman can do except maybe to try a new magnetron.
It is a job for an experienced Panasonic Microwave repair man.

1200 watt panasonic genius shuts down


If it stops after 7 seconds, it has a problem with the inverter.

If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter, controller, magnetron, or a bad connection from one or the other.

Display codes H95, H97, H98 or H99 mean that there's a problem with your inverter, magnetron, or digital programming circuit.

That may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.

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

Doesn't work


No model number?? I'd be pretty suspicious why someone removed the model / serial tag!!

I'd be even more suspicious if someone sold you a microwave with such a serious problem without informing you of it in the auction item description beforehand.

H98 means you have a bad inverter, magnetron, or control board.

You can find a troubleshooting chart for this error code here.
