Panasonic NN-SN67KS Repair Guide
A countertop inverter microwave with genius sensor cooking. Inverter technology delivers genuinely continuous reduced power rather than pulsing full power, which defrosts far more evenly.
Common problems & typical repair costs
| Problem | Likely cause | Typical fix | OEM part # | Typical cost |
|---|---|---|---|---|
| Stops heating entirely | Inverter board or magnetron failure | Professional diagnosis — inverter boards are a specific part | — | $155–$355 |

| Turntable not rotating | Coupler, ring or trapped debris | Clean; replace ring or coupler | — | $0–$40 |

Tech notes
H97 and H98 are inverter faults specific to Panasonic and cannot be fixed with generic microwave parts. On a countertop unit an inverter fault is almost always the end of the appliance.
