Parts for Whirlpool WRS321SDHB05: Unit Parts

The Fan Blade is an OEM part for Whirlpool refrigerators. It helps cool down the condenser coils by drawing air over them, providing cooling and temperature regulation inside the refrigerator.

A bad fan blade can be caused by wear and tear, damage from debris or foreign objects, or motor malfunctions. If you notice issues such as poor cooling performance, unusual noises coming from the refrigerator, or the fan not spinning properly, it may indicate a problem with the fan blade.

Symptoms of a bad fan blade include:

• Inadequate cooling or temperature fluctuations 
• Unusual noises coming from the refrigerator
• The fan not spinning or spinning slowly

Replace your faulty fan blade with this genuine OEM part to restore your refrigerator. 

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

This air baffle directs and controls cold airflow inside the refrigerator compartment to help maintain even temperatures and proper circulation. Replaces a cracked, warped, or missing baffle to restore intended airflow paths. What it does

• Directs cold air from the evaporator into the refrigerator compartment for balanced cooling.
• Helps prevent uneven temperatures and localized warm or cold spots.
• Reduces excessive airflow directly onto stored items that can cause freezing or drying.
• Can rattle or obstruct airflow when cracked or loose, causing noise or reduced performance.

• One air baffle

• Disconnect power to the appliance before beginning work.
• Installation typically requires removing shelves or drawers for access; handle plastic parts gently to avoid damage.
• Align tabs or tracks and snap the baffle into place; do not force or bend beyond natural fit.

This is an evaporator that is located inside many refrigerators. It has a part to play in ensuring the items inside the appliance stay cold. When the refrigerator turns from a liquid into a gas through evaporation, it cools the area nearby and makes it ideal for storing perishable food items. The evaporator pulls air from the refrigerator and blows it over the coils to keep it at the appropriate temperature. There are several signs that the evaporator is damaged or no longer working correctly. Sometimes it will make a chirping or squealing noise. It may cause the refrigerator to be too warm, which may cause issues with the food items inside. Frost buildup on the coils is also a bad sign. If the evaporator is damaged, it needs to be replaced. Unplug the refrigerator and remove the panel over the evaporator. Remove the clamps to uninstall the part. The new part can be installed in the same place. Make sure to test before use.This evaporator is made to be compatible with Maytag, Whirlpool, KitchenAid, and Kenmore refrigerators. It is directly sourced from the manufacturer and sold on an individual basis. This is an authentic OEM replacement component.

This replacement clip secures the defrost heater to the evaporator so the heater stays in proper contact and defrosts frost buildup efficiently. Durable, OEM-style retention clip designed for refrigerators. What it does

• Secures the defrost heater to the evaporator assembly to ensure consistent defrost cycles
• Prevents the heater from shifting or coming loose, which can cause frost buildup or interrupted defrosting
• Helps maintain proper contact for efficient heat transfer during defrost
• Small, inexpensive part that can prevent larger ice/frost-related issues

• Disconnect power to the appliance before accessing the evaporator compartment.
• Handle the evaporator fins and heater element carefully to avoid damage.
• Typically installs with basic hand tools; replace any damaged or corroded clips.

The Condenser Fan Motor is an OEM part for Whirlpool brand bottom-mount refrigerators. This motor powers the condenser fan which dissipates heat from the refrigeration system coils, maintaining cool interior temperatures.

Causes of failure include normal bearing wear from continuous rotations, or buildup obstructing free blade movement. 

Symptoms of a faulty motor include:  

• Elevated interior temperatures and frost propagation issues   
• Extended run times and higher energy consumption
• Grinding or buzzing noises emanating from the refrigeration system area

This Whirlpool replacement restores efficient heat removal and preserves food freshness. Compatible with KitchenAid, Maytag, and some Kenmore models too, it prevents future repair bills.
 

This evaporator tray collects defrost and condensation water from the evaporator assembly to help prevent leaks and water pooling inside the refrigerator. It fits under the evaporator to route meltwater to the drain system. What it does:

• Catches and channels defrost/condensation water away from internal components
• Helps prevent water pooling or dripping inside the fresh food or freezer compartments
• Supports proper defrost drainage to reduce ice buildup around the evaporator
• Works with the drain tube and pan to direct water toward the drain and evaporator pan

• Disconnect power to the appliance before beginning service
• Access may require removing interior panels or the evaporator cover—handle evaporator fins and sensors with care
• Inspect and clear the drain tube and gasket while replacing the tray for optimal performance

This condenser fan motor bracket secures the condenser fan motor to the appliance chassis, keeping the cooling fan stable so it can move air across the condenser for proper cooling performance and prevent wobble or contact. What it does:

• Holds the condenser fan motor in the correct position so the fan blades clear surrounding components.
• Stabilizes the motor to reduce vibration and noise caused by a loose or damaged mount.
• Helps maintain proper condenser airflow to avoid overheating or reduced cooling.
• Can be replaced when the original bracket is bent, cracked, or broken and no longer supports the motor.

• Disconnect power before starting any repair to avoid electric shock.
• Verify motor and fan assembly alignment when reinstalling the bracket; secure mounting hardware snugly but do not overtighten.
• Inspect related fasteners and fan components for wear and replace as needed.

This defrost heater mounts at the freezer's evaporator and melts frost during the automatic defrost cycle, keeping airflow unobstructed and temperatures stable. Replace a failed heater to clear ice buildup and restore proper cooling performance. What it does:

• Heats the evaporator coil at set intervals to melt accumulated frost/ice
• Prevents ice from blocking airflow between freezer and refrigerator sections
• Helps maintain consistent temperatures and efficient cooling
• Common symptoms of failure: thick frost on the back freezer wall, weak airflow, refrigerator warming while the freezer seems cold, fan noise from ice contact

• Disconnect power before servicing; allow heavy ice buildup to thaw safely
• Access the heater behind the freezer's rear panel at the evaporator
• Transfer any clips/shields as needed; route wires exactly as the original and keep the element clear of plastic parts
• Handle the element carefully; avoid bending or stressing it, then reassemble and monitor temperatures over several hours

This grommet is a small protective seal used where a hose, tube, wire, or component passes through or mounts to the appliance cabinet. It cushions the connection and helps prevent leaks, vibration, and wear for reliable operation.
