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.

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

H98 error code


H98 is an error code related to a problem in the high voltage section. I would think that you should be able to get an estimate over the phone locally to determine if you want to proceed with repair or replacement.
