LG Microwave Oven Magnetron

The LG Microwave Magnetron (Part Number: 2B71732F) is an authentic original equipment manufacturer (OEM) replacement component designed for LG microwave ovens. Operating as the primary heating core inside the appliance, this high-voltage component converts DC electrical energy into high-frequency electromagnetic radiation (microwaves), directing it into the cooking cavity to excite water molecules in food.

Key Features

• Genuine OEM Fitment: Engineered directly by LG to ensure precise wave-guide mounting flange alignment, antenna placement, and terminal clip fitment.

• Integrated Mesh Shielding Gasket: Features a pre-installed metallic RF mesh gasket surrounding the antenna dome to prevent microwave energy leakage.

• Heavy-Duty Heat Dissipation: Constructed with aluminum cooling fins designed to withstand high thermal loads during extended cooking cycles.

Benefits

• Resolves non-heating microwave issues where the timer counts down, internal light works, and plate spins, but food stays cold.

• Replaces shorted, burned, or failing magnetron tubes to restore original factory heating speeds.

• Direct replacement ensures certified electrical and radiation safety compliance.

Applications

Designed specifically for select LG microwave oven models requiring part number 2B71732F.

What's Included

• 1 x Genuine LG Microwave Magnetron Assembly (2B71732F)

Usage Instructions

1. DANGER: Unplug the microwave oven from the power outlet and allow high-voltage components to sit.

2. Remove the outer metal cabinet shell screws and lift off the casing.

3. CRITICAL: High-voltage capacitors carry lethal electrical charges even when unplugged. Safely discharge the capacitor using an insulated screwdriver across the terminal posts to the metal chassis.

4. Disconnect the high-voltage wire harness plugs attached to the magnetron terminals.

5. Unscrew the mounting bolts holding the magnetron to the wave-guide.

6. Align the new LG 2B71732F magnetron, ensuring the RF mesh gasket is seated properly against the wave-guide opening, tighten mounting screws, reconnect terminal plugs, reassemble the cabinet, and test heating performance.

Safety Instructions

• LETHAL VOLTAGE WARNING: High-voltage microwave circuitry carries dangerous electrical potential. Repairs should be performed by a qualified appliance technician taking proper safety precautions.

• Never operate the microwave with its outer cabinet removed or with a damaged RF mesh gasket.

Care Instructions

• Keep cooling airflow pathways clear of dust and grease buildup to maintain optimal operational cooling.
