Parts for Kitchenaid KMHC319EBS3: Interior And Ventilation Parts

The Light Bulb is an OEM part for Whirlpool microwaves. It provides illumination within the microwave cavity, enhancing visibility so you can monitor your cooking without opening the door. This feature is essential for convenience and to ensure proper cooking, as it helps to prevent heat loss and maintain the microwave’s energy efficiency.

Symptoms of a bad Light Bulb include:

• The microwave interior remaining dark despite the appliance being in use.
• Flickering or inconsistent lighting when the microwave is operating.
• The bulb not turning on, indicating it may be burnt out or there is a connection issue.

Causes of a bad light bulb can include filament wear out due to prolonged use, damage from moisture or grease exposure inside the microwave, or electrical surges that can shorten the bulb's lifespan.

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models, ensuring it fits a wide range of microwave models.

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.

This replacement lower cabinet base restores the appliance's bottom support and underside protection to help maintain stability and keep internal components shielded from debris. Fits the factory location under the appliance cabinet. What it does

• Provides structural support for the appliance's lower section to reduce wobble and sag.
• Protects motors, wiring and other components from dirt, moisture and impact at the underside.
• Helps stop or reduce unusual rattling or scraping caused by a damaged or missing base.
• Restores proper clearance and mounting for kickplates and toe panels.

• Disconnect power and, if applicable, gas and water before starting any work.
• Use two people to support the appliance when accessing or replacing the base.
• Keep all factory fasteners; re-use or replace with equivalent OEM screws as required.

The Reflector is an OEM part for Whirlpool microwaves. It is located inside the microwave cavity behind the waveguide and works to redirect electromagnetic waves for more even cooking.  

Symptoms of a damaged reflector include:

• Inconsistent or incomplete heating of foods during cooking
• Hot and cold spots forming within the microwave cavity
• Lower overall power output from the microwave

Causes of reflector damage can be cracking or pitting of the reflective aluminum surface over multiple heating cycles. Impact incidents from user error may also damage its shape.

This OEM Whirlpool replacement assists in delivering uniform energy distribution for optimal microwave performance. This part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, and Roper microwave models.

The Interlock is an OEM part for Whirlpool microwaves. It is an important safety mechanism that monitors the door latch and prevents microwave operation when the door is open. 

Symptoms of a faulty interlock include:

• The microwave fails to start or run when the door is open  
• Buzzer sounding indicating a blocked safety device
• Door unable to latch or stay closed securely

Causes can be due to worn contacts within the interlock from repetitive door opening cycles. Over time, this safety component becomes fatigued.

Replacing with this new OEM interlock protects against unintentional microwave exposure by ensuring the door remains closed during operation. Peace of mind is restored with a working safety mechanism.

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.
