Parts for Kitchenaid YKMHS120EBS4: Air Flow Parts

This air deflector redirects airflow inside the appliance to help maintain proper circulation and protect components from direct airflow. Replacing a damaged deflector restores intended air paths and can reduce uneven temperature or noise. What it does

• Guides air where the manufacturer intended to ensure even circulation.
• Protects nearby components from direct airflow and wear.
• Helps reduce symptoms like uneven cooling/heating or unusual airflow noise.
• Works as a passive airflow-management part — no electrical connection.

• Disconnect power to the appliance before starting any repair.
• Handle the deflector carefully to avoid cracking plastic tabs during removal or installation.
• Installation typically requires basic hand tools; for exact steps.

This lamp cover is the replacement lens that protects and diffuses your oven's interior light, restoring even illumination while keeping the bulb shielded from heat and food residue. It helps maintain safe, usable oven lighting. What it does:

• Protects the oven light bulb from splashes, crumbs and direct contact.
• Diffuses the bulb for more even interior illumination.
• Replaces a cracked, cloudy, melted or missing lens that can cause dim or exposed lighting.
• Fits over the lamp housing to restore the oven's normal light appearance and function.

• Disconnect power to the appliance before starting and allow the oven to cool completely.
• Handle the cover carefully—wear gloves to protect from sharp edges or broken glass.
• Remove any retaining screws or clips, swap the old cover for the new one, then secure the retainer.
• After installation, restore power and replace the bulb if issues persist.

The 40W Light Bulb is an OEM replacement part for Whirlpool microwave ovens. It is a standard-size bulb designed to provide illumination inside the microwave cavity, allowing you to easily view and monitor the cooking or reheating process.

Symptoms of a faulty microwave light bulb include:

• Dimming or flickering light during operation
• Complete bulb failure or no illumination within the cavity
• Discoloration or physical damage to the bulb itself

Causes of a bad microwave light bulb can include normal wear and tear over time, electrical surges or voltage fluctuations, or physical impact or vibration during use.

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

The Vent Fan Motor is an OEM replacement part for Whirlpool microwaves. It is responsible for removing steam, smoke, and odors from the microwave during cooking.

A bad vent fan motor can occur due to regular wear and tear, electrical issues, or motor failure. If you notice problems such as the vent fan not operating or making unusual noises, it may indicate a problem with the motor.

Symptoms of a bad vent fan motor include:

• Vent fan not turning on or functioning properly
• Unusual noises or vibrations coming from the vent area
• Insufficient ventilation and removal of steam or odors  

Replace your faulty vent fan motor with this genuine OEM part to restore your microwave. 

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

This Charcoal Filter is an OEM replacement part for Whirlpool microwaves. The charcoal filter is responsible for improving the air quality in the kitchen by removing impurities and odors from the air. It is used to remove smoke, grease, and cooking odors as it is drawn up through the vent fan. By trapping these particles, the filter helps maintain cleaner air in the kitchen and prevents odors from recirculating and affecting the taste and smell of your food.

Causes of a bad Charcoal Filter include saturation from absorbing smoke and odors over time, accumulation of grease and particles that clog the filter, leading to decreased effectiveness, and physical damage that compromises its ability to filter air properly.

Symptoms of a bad Charcoal Filter include:

• Persistent odors in the kitchen after cooking.
• Smoke not being effectively vented out during microwave use.
• Reduced airflow from the microwave's venting system.

Replacing the charcoal filter at regular intervals or when these symptoms are noticed ensures that your microwave continues to operate efficiently and keeps your kitchen air clean. This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

Description- Color: metallic. Measures about 5 inches wide by 5 inches deep.

This replaceable refrigerator water filter cartridge helps restore clear, better-tasting drinking water and ice by capturing sediment and common impurities. Designed for a quick swap to keep your fridge dispensing clean water. What it does:

• Filters sediment and particulate to reduce cloudiness in water and ice
• Helps improve taste and odor commonly associated with older filters
• Restores normal water flow and delivery when a clogged filter causes slow dispensing
• Supports routine maintenance to help prevent scale and buildup in the dispenser system

• Shut off the refrigerator water supply before removal to limit spills
• Follow the refrigerator manufacturer's removal/installation motion (push, pull, twist, or bayonet style)
• Flush several full glasses of water after installation to clear air and initial carbon fines
• Check for leaks at the filter and housing after restoring the water supply; discard the old filter per local regulations

This Light Housing secures and protects the interior lamp assembly, helping keep the compartment safely illuminated. Replace a cracked or heat-damaged housing to restore a stable bulb fit and consistent lighting performance. What it does:

• Provides a stable mount for the interior light bulb/socket
• Shields nearby wiring and components around the lamp area
• Helps position the light for proper illumination inside the compartment
• Common signs of wear: cracked or melted housing, loose bulb fit, lens/cover won't stay attached, intermittent lighting from a poor physical connection

• 1 light housing

• Disconnect power to the appliance before servicing
• Remove the lens/cover and bulb, then unfasten the damaged housing
• Transfer the existing socket, wiring, and any hardware from the old housing as needed
• Reinstall the housing, replace bulb/cover, restore power, and test the light

This microwave magnetron is the high-voltage tube that generates the microwave energy to heat food. When it fails, the oven may run but not heat or heat very slowly. Replacing it restores normal cooking performance. What it does:

• 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

This air duct routes dryer exhaust air between the drum housing and the external vent to help proper airflow and safe venting. Replaces a damaged, cracked, or disconnected duct to restore consistent drying performance. What it does:

• Channels heated air from the dryer to the external venting system
• Helps maintain proper airflow to avoid long dry times and possible overheating
• Prevents lint buildup in inaccessible gaps when intact and sealed
• Reduces rattling or vibration caused by a loose or broken duct section

• Disconnect power (and gas, if applicable) before starting any repairs

This is a thermal safety fuse that opens the circuit if temperatures rise beyond a safe limit, protecting the appliance from overheating and preventing further damage. Replacing a failed fuse restores power to the affected circuit once the underlying cause is addressed.

• Monitors temperature in a protected circuit and cuts power if unsafe heat is detected
• Helps prevent overheating-related damage
• Typical failure signs: no power/no operation, cycle won't start, shuts off mid-cycle after overheating event
• Must not be bypassed; replace if open and investigate the root cause of overheating

• Unplug appliance or disconnect power before service
• Verify the fuse is open with a multimeter; replace only after correcting any airflow/overheating issues
• Install in the same orientation and location as the original to ensure proper temperature sensing
• Handle wiring carefully; transfer connectors one at a time to avoid miswiring
