Microwave Magnetron 2M261-M32K5Y (№26)

Genuine Inverter Magnetron for Panasonic Microwave Ovens (Part Number: 2M261-M32K5Y / Position No. 26)

The heart of your microwave oven — 100% genuine original service part from Panasonic.

Is your microwave running and the timer counting down, but the food remains completely cold? More often than not, this indicates a failure of the magnetron—the core component that generates microwave radiation.

The Panasonic 2M261-M32K5Y is a high-tech, inverter-type magnetron. Unlike conventional transformer-driven magnetrons, it is designed to operate with continuous, smooth power modulation (Inverter technology). This ensures uniform heating of your dishes without drying them out, perfectly preserving the texture and nutrients of the food.

Technical Specifications & Compatibility:

• Model / Part Number: 2M261-M32K5Y

• Brand: Panasonic (Original)

• Control Type: inverter

• Service Diagram Position: In official factory documentation and service schematics, this magnetron is designated as Position No. 26 

• Model Compatibility: engineered specifically for the flagship inverter steam microwave oven Panasonic NN-DS592M (NN-DS592MZPE). It is also fully compatible with other premium Panasonic inverter microwave models that feature this magnetron series straight from the factory.

Why Is It Critical to Use a Genuine Original Magnetron for Inverter Ovens?

• Inverter Board Protection: inverter power supply boards in Panasonic ovens (especially within the NN-DS592M series) are extremely sensitive to precise electrical parameters. Installing a generic, third-party, or "universal" magnetron with different resistance or inductance ratings will almost certainly destroy the expensive inverter board within the first few minutes of operation.

• Optimized Air Cooling: the orientation of the radiator cooling fins and the exact geometry of the mounting holes on the 2M261-M32K5Y model are perfectly calibrated to match the internal airflow paths of the NN-DS592M chassis. This prevents critical overheating during extended combination cooking cycles (such as simultaneous Steam and Grill modes).

• Rigorous Quality Control: every genuine factory part undergoes strict inspection and testing for microwave window (antenna cap) hermetic sealing and high-voltage feedthrough capacitor insulation.

Symptoms That Your Magnetron (No. 26) Needs Replacement:

1. The oven starts up and the fan spins normally, but it completely fails to heat up water or food.

2. Violent sparking, arcing, or loud crackling noises occur inside the cooking cavity near the mica wave-guide cover during operation.

3. Activating the microwave mode produces an unusually loud, deep hum or buzzing sound, after which the oven may automatically shut down and display a system error code (e.g., H97 or H98).

4. Physical inspection of the magnetron reveals burn-through holes on the metal antenna cap or visible cracks across the ferrite ring magnets.
