That code indicates a problem with the magnetron, inverter or control board.

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. You can find one here:

SOURCE: Panasonic Microwave show H98 in window

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

It 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.

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.

Hi, I have a Panasonic Inverter microwave NN-Sn9688. It's less than a year old and when you press the START button H98 appears and it will not start. Everything else works, clock etc and reset/stop...


Hi Judith, I am Kelly

If this has a 1 year warranty it is time to make that call.

Otherwise see this link about H97 or H98 codes: http://www.applianceaid.com/micro_faultcodes.html#panasonic

There are a few things that can cause the problem, none of them cheap repairs. The Magnetron filament, Control board and Inverter are the top 3 other than a losse connection.

I tried running the Model number NN-SN9688 and it does not cross. See Panasonic link here: http://www2.panasonic.com/webapp/wcs/stores/servlet/PNAEndecaSearchCmd?N=779832097&Ne=&No=0&Nr=12001&Ns=&Ntk=SupportSearch&URL=vSupportSearch&cmTag=true&catalogId=11017&storeId=15001&cm_sp=SiteSearch-_-SupportSearch-_-SupportHome&Ntt=NN-SN9688&x=28&y=20

I did not go to Panasonic Global and try other countries. I just did a USA search.

Thanks for choosing FixYa.
