The tech spent less than 10 minutes pushing buttons on the unit and 20 to 30 minutes in his vehicle getting pricing to replace all of the controls.

Noise Filter
Genuine Whirlpool part
By: Whirlpool
Part Number: W11398764

The Noise Filter is an OEM component specifically designed for Whirlpool microwaves. It works to dampen vibrations and reduce noise originating from the microwave's internal mechanisms during use. 

Causes of a bad noise filter include degradation of the noise-dampening material over repeated heating cycles. Microwave usage subjects the filter to heat and vibration stress.

Symptoms of a bad noise filter include:

  • Increased volume levels emanating from the microwave cabinet
  • Louder high-pitched whining or buzzing sounds  
  • Vibrations felt on the exterior of the microwave body

This OEM Whirlpool replacement noise filter helps ensure a quiet cooking experience. Its precise design and durable construction minimize disruptive sounds. Please replace yours if you notice louder than normal operation noise. 

This part is also compatible with some KitchenAid, Jenn-Air, Amana, and select Kenmore and Frigidaire microwaves.
