LG Microwave Oven Varistor

The LG Varistor (Part Number: 6102JB8001B) is an authentic original equipment manufacturer (OEM) replacement voltage-dependent resistor (VDR / Metal Oxide Varistor) designed for LG microwave ovens, refrigerators, and major household appliances. Soldered directly onto the main electronic control PCB near the AC power input lines, this protective semiconductor component maintains high electrical resistance under normal line voltage, rapidly dropping its resistance during sudden voltage surges to safely divert over-voltage energy away from sensitive microprocessors and integrated circuits.

Key Features

• OEM Transient Voltage Protection: Factory-calibrated clamping voltage characteristics absorb high-energy electrical spikes without damaging downstream control board electronics.

• Nanosecond Response Time: Clamps voltage transients in nanoseconds to protect power supplies against utility grid fluctuations, inductive switching spikes, and lightning surges.

• Radial-Leaded Radial Disc Design: Compact radial-lead construction engineered for precise through-hole soldering on LG main control boards.

Benefits

• Saves expensive main control boards from burning out during power surges or electrical storms.

• Replaces shorted, charred, or blown varistors to restore full circuit surge protection.

• Direct OEM replacement guarantees factory-certified electrical safety and clamping specs.

Applications

Designed specifically for select LG microwave ovens, refrigerators, and range appliances requiring part number 6102JB8001B.

What's Included

• 1 x Genuine LG Control Board Varistor (6102JB8001B)

Usage Instructions

1. DANGER: Unplug the appliance from the electrical power outlet and allow all high-voltage capacitors to discharge fully before starting work.

2. Access the main electronic control PCB compartment.

3. Unscrew and carefully lift the control board out of its plastic housing.

4. Desolder the damaged varistor terminal leads from the underside of the PCB using a soldering iron and desoldering pump.

5. Insert the new LG 6102JB8001B varistor leads into the PCB holes, solder securely into place, trim excess lead length, reassemble the board housing, and test power.

Safety Instructions

• Disconnect main AC electrical power prior to opening appliance cabinets or handling electronic boards.

• PCB desoldering and soldering require proper electronic repair equipment and soldering skill.

Care Instructions

• Ensure the control board compartment remains dry and free of dust or moisture accumulation.
