LG Microwave Oven Capacitor,High Voltage

The LG Microwave High-Voltage Capacitor (Part Number: 0CZZW1H004S / Model: CH85-21110) is an authentic original equipment manufacturer (OEM) replacement component designed for LG microwave ovens. Working within the microwave power supply circuit, this high-voltage oil-filled capacitor doubles peak AC voltage from the power transformer, storing and discharging electrical energy to power the magnetron tube during heating cycles.

Key Features

• OEM Precision Specifications: Rated at 1.10µF ± 3% capacity and 2100V AC operating voltage (50/60Hz) to ensure factory-calibrated magnetron power output.

• Integrated Bleeder Resistor: Built-in internal 10MΩ safety bleeder resistor automatically discharges high voltage across the capacitor terminals when microwave power is turned off.

• Dual 2-Terminal Insulated Posts: Features heavy-duty insulated terminal posts with quick-connect spade lugs for safe and secure wire lead attachment.

• Aluminum Casing: Hermetically sealed metal body engineered to withstand internal electrical and thermal stresses.

Benefits

• Solves heating failure issues where the microwave runs, hums, or counts down but fails to heat food.

• Replaces shorted, open, or leaking capacitors to restore proper magnetron excitation voltage.

• Direct replacement ensures exact mounting bracket fitment and terminal alignment.

Applications

Designed specifically for select LG microwave oven models requiring part number 0CZZW1H004S.

What's Included

• 1 x Genuine LG Microwave High-Voltage Capacitor (0CZZW1H004S / CH85-21110)

Usage Instructions

1. DANGER: Unplug the microwave oven from the power outlet before starting repairs.

2. Remove the outer metal cabinet casing.

3. CRITICAL: High-voltage capacitors retain lethal charges even when unplugged. Manually discharge the capacitor terminals using an insulated 20kΩ resistor or heavy-duty insulated pliers across both terminal posts to the metal chassis.

4. Note the wire terminal positions on the old capacitor, then disconnect the high-voltage wires and diode leads.

5. Unscrew the mounting strap holding the old capacitor.

6. Install the new LG 0CZZW1H004S capacitor into the bracket strap, reattach the wire leads to the correct terminals, reassemble the cabinet shell, and test heating.

Safety Instructions

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

• Always discharge the capacitor manually before touching any internal electrical components.

Care Instructions

• Keep terminal posts and insulator sleeves clean and free of metal dust or grease. No ongoing maintenance required once sealed inside the cabinet.
