GE WB27X10011 Microwave High Voltage Capacitor

Genuine OEM High Voltage Power Supply Circuit Capacitor Module

Product Overview

The GE WB27X10011 is a genuine OEM microwave high voltage capacitor assembly. Mounted inside the high-voltage cavity behind the outer cabinet casing, this critical electrical component works in tandem with the high voltage transformer and high voltage diode to form a voltage-doubling circuit. By stepping up the operating voltage to approximately 2,000+ volts, it supplies the intense DC electrical energy required by the magnetron tube to generate microwave energy for cooking food.

As an Authentic General Electric Factory Certified Replacement Component , this high voltage capacitor directly replaces older or cross-referenced catalog part numbers including 2501-001011 , 769837 , AH238803 , AP2026197 , EA238803 , EAP238803 , and PS238803 . Encased in a hermetically sealed aluminum metal body housing an internal 10MΩ bleeder resistor, it is precision-engineered for maximum dielectric strength, heat dissipation, and long-term electrical reliability.

When to Replace the High Voltage Capacitor

• Microwave Runs & Lights Up but Does Not Heat: The turntable spins, lights illuminate, and the fan runs, but food items remain completely cold due to a failed high-voltage power circuit.
• Loud Humming or Buzzing Noise During Operation: The microwave emits a deep electrical hum or groaning noise when heating cycles initiate, indicating a shorted or severely degraded capacitor under load.
• Blown High Voltage / Main Fuse Immediately on Start: Pressing "Start" immediately trips the home circuit breaker or blows the internal high-voltage safety line fuse due to an internal short inside the capacitor housing.
• Visually Swollen, Bulging, or Leaking Capacitor: Physical inspection reveals oil leakage, bulging seams, or burnt terminal insulators on the aluminum capacitor case.

Professional Installation & Safety Guidelines

⚠️ DANGER — HIGH VOLTAGE LETHAL SHOCK HAZARD: Microwave capacitors store LETHAL levels of electrical energy (over 2,000 Volts) even when the appliance is completely UNPLUGGED from wall power. DO NOT touch capacitor terminals or internal high-voltage wiring without first unplugging the unit AND manually discharging the capacitor. Discharge by shorting insulated-handle needle-nose pliers or a high-wattage resistor across both sets of spade terminals AND to the metal chassis ground.

Pro Tip (Multimeter Testing): Before replacing, disconnect power, safely discharge the capacitor, and test terminals with a digital multimeter set to Ohms (Ω). Measure resistance across terminals: a functioning capacitor should momentarily show low resistance and charge up toward infinite resistance. If it measures 0 Ohms permanently (shorted) or infinite resistance right away without charging, the capacitor is dead. Installation Access: Unplug the microwave power cord, remove outer cabinet screws, and slide off the metal wrapper to reach the high-voltage component bracket. Installation Hack: Take a clear smartphone photo showing which colored wire leads and high-voltage diode terminals connect to each terminal post. Use needle-nose pliers to remove wire spade connectors carefully. Warning: Unbolt the mounting bracket strap, remove the old capacitor, align the new WB27X10011 unit, re-clamp the bracket firmly, reconnect wire leads according to your photo, reassemble the cabinet wrapper, restore power, and test heating with a glass of water.
