LG Microwave Oven Fuse Holder

The LG Oven-Range Fuse Holder Assembly (Part Number: 4930W3B025E) is an authentic original equipment manufacturer (OEM) replacement power distribution component designed for LG microwave ovens and range-oven appliances. Positioned inside the rear electrical compartment near the power cord entry point, this mounting block securely houses the main ceramic line fuse, providing high-conductivity spring clips and spade terminal connections to route mains electrical power safely into internal control circuits.

Key Features

• Genuine OEM Electrical Safety: Engineered directly by LG to ensure exact terminal pin spacing, mounting hole alignment, and insulation rating.

• Flame-Retardant Insulated Housing: Molded from high-temperature thermoplastic that prevents electrical tracking, arcing, and thermal damage.

• High-Tension Metallic Spring Clips: Features spring-loaded metal clip terminals that grip ceramic ceramic fuses firmly, preventing loose contacts and resistance heating.

Benefits

• Replaces cracked, melted, or scorched fuse blocks caused by loose fuse connections or short-circuit overheating.

• Solves power loss issues where melted fuse clips prevent electricity from reaching internal microwave components.

• Direct bolt-in fitment ensures factory-certified electrical safety compliance.

Applications

Designed specifically for select LG microwave oven and range-oven models requiring part number 4930W3B025E.

What's Included

• 1 x Genuine LG Microwave Oven-Range Fuse Holder Assembly (4930W3B025E)

Usage Instructions

1. DANGER: Unplug the appliance from the electrical power outlet or turn off power at the main breaker box before starting work.

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

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

4. Locate the fuse holder block near the power cord strain relief.

5. Disconnect the wire harness spade leads from the old fuse holder terminals.

6. Unscrew the mounting bracket screw, remove the old block, position the new LG 4930W3B025E holder, secure with screws, reinsert the line fuse, attach wire leads, reassemble the cabinet, and test power.

Safety Instructions

• Disconnect main AC electrical power prior to opening cabinet panels or handling internal wiring.

• Ensure wire terminals are pressed tightly onto spade connectors to prevent high-resistance electrical overheating.

Care Instructions

• Keep terminal clips clean and free of corrosion or grease. No ongoing maintenance required once installed.
