Question about Microwave Ovens
After setting the timer and turning on the display reads H97
and will not starty.
H95, H97, H98 or
H99 mean that there's a problem with your inverter,
magnetron, or digital programming circuit.
If the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle. 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.

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.
