Panasonic Microwave Microwave Inverter F606Y9X90AP, Replaces 1726515136
A Panasonic inverter microwave that heats unevenly, runs but produces no heat, or loses power output is almost always a failed inverter board. In most Panasonic NN-series inverter microwaves, the inverter board is the core power control component — it replaces the traditional transformer with a variable-frequency power supply that delivers precise, continuous power to the magnetron at any wattage level from low to high. When it fails, the magnetron receives no power or incorrect power — the microwave runs but produces no heat, heats only at full power regardless of the setting, or shuts off mid-cycle on a thermal fault. ⚡ Common failure point in Panasonic NN-SD, NN-SN, NN-SE, and NN-SA series inverter microwaves. Part F606Y9X90AP is the certified refurbished Panasonic inverter board that restores full, precise power output across all wattage settings — the genuine fix for inverter-related heating failures.

Is This the Right Part?
Confirm the complete model number before ordering. Similar parts may use different connectors, dimensions, hose positions, electrical ratings, or mounting points.
- ✔ Microwave powers on — display works, door interlock functions normally
- ✔ Magnetron has been tested or ruled out as the primary fault
- ✔ Thermal cutout and high-voltage fuse test good (continuity confirmed)
- ✔ ONLY problem is no heat output, uneven heating at any power level, or microwave shuts off mid-cycle
- Microwave runs but produces no heat — food remains cold after a full cycle
- Microwave heats unevenly — hot spots and cold spots regardless of power level setting
- Microwave only heats at full power — lower power settings have no effect
- Microwave shuts off mid-cycle with no error code — thermal protection tripping
- Humming or buzzing from the inverter area without heat being produced
- Display works normally but magnetron never activates during a cook cycle
- Part Number: F606Y9X90AP
- Type: Microwave Inverter Board (Variable-Frequency Power Supply / Magnetron Driver)
- Condition: Certified Refurbished — inspected and tested before shipping
- Brands: Panasonic
- Status: ⚠️ New OEM Discontinued (NLA) — certified refurbished units while supplies last
Both a failed inverter and a failed magnetron cause a microwave that runs but doesn’t heat. The key diagnostic difference: if the microwave heats at full power but not at lower power settings, the inverter is almost certainly the fault — the magnetron is receiving power but the inverter can’t modulate it. If the microwave produces no heat at any power level, either component could be at fault and both need to be tested by a qualified technician before ordering. Never replace the inverter without ruling out the magnetron first.
