Whirlpool W11256462 Microwave High Voltage Diode – Genuine OEM Replacement Part

The Whirlpool W11256462 Microwave High Voltage Diode is a genuine OEM replacement part designed to restore proper heating performance in select Whirlpool-built microwave ovens. Supplied by Appliance Kingdom, this original Whirlpool component meets strict manufacturer standards for safety, reliability, and performance. It is compatible with a wide range of microwave models from Whirlpool, Maytag, KitchenAid, Amana, and other Whirlpool-family brands. Always verify your microwave model number before ordering to ensure correct compatibility.

Function & Importance

The high voltage diode plays a critical role in the microwave’s heating system. It works alongside the capacitor and magnetron to convert alternating current (AC) into direct current (DC), allowing the magnetron to generate microwave energy. Without a properly functioning diode, the microwave may power on but fail to heat food. Because this component handles extremely high voltage, it is essential for both efficient heating and safe microwave operation.

A faulty diode can disrupt the entire high-voltage circuit, making replacement necessary to restore normal cooking performance.

Common Symptoms Indicating Replacement

You may need to replace the W11256462 microwave high voltage diode if you experience:

  • Microwave runs but does not heat food

  • Food takes significantly longer than usual to warm

  • Loud humming or buzzing sounds during operation

  • Burning smell or visible damage near the high-voltage components

  • Intermittent heating issues

These symptoms are common indicators of a failing microwave heating component and should be addressed promptly.
