Magnetron 2M261-M36U16 (Witol) — The "Heart" of Your Premium Microwave
Leave cold food in the past! If your flagship Panasonic microwave has stopped heating but all other functions are working perfectly, it’s time to replace the magnetron. We offer a fully compatible, original 2M261 series magnetron manufactured by Witol—an industry leader (also supplied under LG/Panasonic brands utilizing this platform). This component is designed specifically for premium steam and convection models and serves as the core power element that generates microwave radiation.
Guaranteed Compatibility
This configuration features a top-terminal layout and a specialized mounting bracket designed for premium 4-in-1 inverter combination ovens:
Panasonic NN-CS89LB (Primary model)
Other CS series models (e.g., CS894, CS885) that feature inverter steam-grill technology and utilize side-radiator cooling.
Key Advantages and Technical Features
Exact Match to OEM Specifications: this part belongs to the 2M261-M36 series. The U16 suffix on the barcode ensures the exact orientation of the air deflectors and mounting brackets required for your specific model. (Note: The U16 suffix is sometimes only printed on the barcode sticker, while the main label displays only M36).
Inverter Reliability: this magnetron is fully optimized to work seamlessly with Panasonic inverter power boards. This ensures smooth power regulation, quieter operation, and a significantly longer lifespan compared to traditional transformer-based models.
Efficient Passive Cooling: the aluminum heat sinks feature thin cooling fins nestled beneath the housing, meticulously engineered for optimal heat dissipation via your oven's powerful built-in fan during long steam or convection cycles.
Compact Top-Facing Connector: the power terminals are positioned on top of the housing, simplifying connection within the tightly packed upper-rear compartment of the appliance.

The microwave operates, the light turns on, and the turntable rotates, but the food remains completely cold.
A strange noise (loud buzzing, humming, or crackling) occurs as soon as the microwave mode starts.
Sparks are visible inside the cooking cavity near the mica waveguide cover.
An H-series error code appears on the display (most commonly H97 or H98).
