Panasonic H97 and H98 Errors
H97 and H98 indicate a fault in the high-voltage inverter circuit or magnetron. The microwave detects that power is not reaching the cavity and stops. We test the inverter board and magnetron and replace the failed part.

Panasonic pioneered inverter microwaves, and their NN-series models are very common in Dubai homes. When a Panasonic stops heating, it often shows H97 or H98, codes that point to the inverter circuit or magnetron.

Panasonic combination microwaves add a grill and convection heater. If only the microwave function fails, the inverter or magnetron is at fault; if only the grill or convection fails, it is the heater, fan or thermal fuse.
Our Panasonic process:
A conventional microwave simulates low power by switching the magnetron fully on and off. Panasonic inverter microwaves deliver genuinely lower, continuous power, which defrosts and simmers more evenly. That is also why the inverter board matters: if it fails, the microwave may not heat at all, or may show H97 or H98. Replacing the board restores the smooth low-power cooking Panasonic is known for.
| Code | What it means | Usual fix |
|---|---|---|
| H97 | Inverter circuit or magnetron fault | Test the inverter board and magnetron; replace the failed part. |
| H98 | Inverter circuit or magnetron fault | Test the inverter board and magnetron; replace the failed part. |
The microwave has detected a high-voltage or magnetron fault. It needs a technician; do not open the casing.
No, we are independent. See Panasonic appliance repair.
Inverter microwaves defrost gently at low power. If defrosting is suddenly uneven or cooks the edges, the inverter circuit may not be regulating power correctly.
Yes, including microwave, grill and convection functions.
No. It needs the correct inverter board for the model.
Overheating from blocked vents or a failing inverter board.
