H98 IS GOING TO BE THE MAGNETRON OR INVERTER OR BOTH, MAY BE BETTER TO REPLACE UNIT. INVERTERS NOT CHEAP. Get full warranty on new unit. If you have this one repaired typically only 90 days warranty and only on the parts you replace.

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

Inverter or magnetron bad.

H97, H98 and H99 appears in display window a short time alter start key is pressed and no microwave oscillation.

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.

If it stops after 22 seconds, that means the controller has detected a problem, usually 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.
