Question about Microwave Ovens

1 Answer

My Panasonic NN-CS596S cuts out after nearly 40 secs on the microwave program, and then displays the H98 code. My contract with the Gas Board provides a call- out engineer, he has changed the Magnatron, but the fault remains. My oven is just over 3 Years old and he says it is not economic to replace other parts. Is he correct? or is it worth my while to have it looked at by a panasonic service/repair centre? Regards Dave

It should be worth having it looked at. The magnetron is the most expensive part to replace, since it is new I would have it looked at it might just be a door or interlock switch(cheap fix). Here is a link for DIY's http://appliancehelponline.com/microwavetroublshootingvideo.html there are also videos on testing each component at http://appliancehelponline.com/microwave.html

Model NN-ST659W works for about 30 seconds then displays H98 on the display panel how do I fix this problem


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.

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.

Panasonic genious sensor inverter 1300w nn-t664sfx displays code "h98" & will not run - what's the problem?


Mine did this once and it was the magnetron. Once replaced, it worked fine. Repair is an option if it is still under warranty or someone will do it on the cheap. Otherwise, just get a new microwave, since this is the main part.

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.

Let us know if the hard reset does not fix it.

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 or a bad magnetron.

If you do indeed have a problem, Since it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

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