The Filter is an OEM part for Whirlpool microwaves. This part filters grease and other particles from the air as it is vented out of the microwave, particularly when the microwave is used in conjunction with a range. This helps to maintain a clean kitchen environment and prevents grease buildup on the microwave’s internal components.

Causes of a bad filter can include accumulation of grease and food particles over time, exposure to high heat, or general wear and tear.  

Symptoms of a bad filter include:

• Reduced ventilation efficiency
• Excessive smoke or steam lingering in the kitchen
• Grease buildup on kitchen surfaces near the microwave
• Unusual odors during microwave operation

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

• Produces the microwave energy that heats food in the oven cavity
• A failed unit can cause the microwave to run but not heat
• Can create an unusual loud humming or buzzing during operation

• Includes 1 magnetron

• Unplug the microwave and discharge the high-voltage capacitor before servicing
• Handle by the mounting surfaces; avoid touching or damaging the antenna and ceramic insulators
• Reconnect high-voltage leads exactly as routed and reassemble cooling airflow parts; test with a cup of water to confirm heat

The Mounting Nut Assembly is an OEM replacement part for Whirlpool microwaves. It securely fastens the microwave to its mounting bracket, ensuring stability and safety during operation. It provides a secure and reliable connection, preventing the microwave from shifting or falling during use.

A bad mounting nut can occur due to various reasons, such as wear and tear, improper installation, or accidental damage. If you notice symptoms such as the microwave becoming loose or wobbly, or if the mounting nut is missing or damaged, it may be time to replace it.

Symptoms of a bad microwave installation mounting nut include:

• Microwave becoming loose or wobbly
• Missing or damaged mounting nut

This Whirlpool replacement part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
