The H98 fault on a Panasonic can be a bad magnetron, inverter or control panel.

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.

NOTE:
DO NOT try to REPAIR this Inverter Power Supply (U) and also DO NOT RE-ADJUST PRESET VOLUME on the board. It is very dangerous to repair or adjust without sufficient test equipment because this circuit handles very high voltage and very large current. Off alignment or inverter board operation is dangerous. Operating a misaligned inverter circuit is dangerous due to the very high voltage and current that is produced by this board. Defective boards must be replaced with a new one.
- Check magnetron filament for open or short to casing before proceeding to determine a good magnetron.

Error code H98


Hello

Unplug the microwave and plug it back in after 30 seconds to make sure the message did not appear because of a simple glitch. If it does not come up again, use the microwave as normal.

The "H98" error means that the microwave's inverter has shorted out and does not work any more. The microwave cannot transfer power to create heat, and the part has malfunctions and requires replacement. Use your microwave serial number and customer service to find the proper part for the microwave.

Your microwave comes with a warranty that will cover the inverter if the warranty is still valid. Call the number for the warranty department or bring the microwave, with receipt, back to the store you purchased it from. This will save you the hassle of replacing the par

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.

Microwave runs for only a few seconds and then an error message of H98 is displayed and quits working Microwave only used for 6 months.


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

In most cases, this is a problem with the inverter or a bad magnetron.

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.

Being 6 months old means it will be repaired free of charge.
