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 in inverters, I do not recommend that an inexperienced person work on these.

Panasonic microwave NN SF550W error code H97


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

H97


H97 is a problem with the inverter, bad magnetron 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:
