Rear Heater (Convection) for Microwave F631DBH20BP (№46)

Original Convection Heating Element (Rear Element) for Panasonic Microwave

Part Number: F631DBH20BP (Position No. 46 on the service diagram)

Turn your microwave into a fully functional conventional oven! If your premium microwave has stopped baking and the convection mode only circulates cold air, it is time to replace the circular heating element.

The genuine Panasonic F631DBH20BP convection heater is a radial power heating element (HEATER CU) located on the rear wall of the cooking cavity, wrapping around the fan blades. It generates intense, dry heat that the fan continuously circulates throughout the entire oven cavity. This ensures perfectly even baking, an excellent rise for doughs, and tender textures without burning.

Key Advantages and Features of the Part

• 100% Genuine OEM Quality: developed by Panasonic engineers specifically for flagship 4-in-1 inverter combination ovens. It features flawless geometry, mounts precisely onto the rear flange of the convection assembly, and perfectly matches the power and resistance requirements of the inverter board.

• Circular (Radial) Shape: the element's geometry is specially tailored to fit around the convection fan blades. Airflow passes directly through the red-hot coil, heating up instantly, which minimizes energy loss and speeds up oven preheating.

• Heavy-Duty Heat-Resistant Alloy: the metal sheath of the heating element is manufactured from a high-grade alloy built to endure prolonged high-temperature stress and the harsh environment of hot steam. The component will not deform, even when operating at maximum temperatures (up to 230°C).

• Multi-Mode Combination Engineering: the design is optimized for long, complex cooking cycles in programs like "Convection + Microwave" or "Convection + Steam", protecting the terminal contact group from overheating under heavy combined loads.

Technical Specifications

Signs That the Convection Element Needs Replacement

1. The convection mode runs cold: the fan on the back wall rotates and you can hear it running, but the air inside the cavity remains cold and food fails to bake.

2. Service error code appears: an H-series error code (related to oven temperature management) lights up on the microwave display, locking out the program.

3. Visible physical breakdown: inspection of the convection assembly reveals burn-throughs, cracks, breaks in the outer sheath, or severe warping of the heating tube.

4. Short circuit: ttempting to turn on the convection or baking mode instantly trips your home's circuit breaker/RCD due to the element shorting out to the chassis.

Important Safety Warning: the rear heating element is integrated into a complex network of thermal sensors and ventilation systems. DIY replacement should only be performed if you have the proper technical skills and after completely disconnecting the microwave from the power source. To preserve your appliance warranty, we recommend having the installation performed by a qualified technician.

Avoid purchasing generic aftermarket heating elements with similar diameters—mismatched power ratings will either leave your food chronically undercooked or cause critical overheating of the inverter board. Only the original Panasonic F631DBH20BP heating element restores the performance of a true professional oven to your appliance.
