Parts for Kitchenaid KSSS42MDX04: 13 - Lower Unit And Tube Parts

The Defrost Thermostat is an OEM part for Whirlpool refrigerators. The thermostat monitors the temperature of the evaporator coil and signals the defrost heater to turn on or off to prevent frost buildup, ensuring efficient cooling.

Causes of a bad defrost thermostat can include wear and tear over time, exposure to extreme temperatures, or electrical malfunctions.  

Symptoms of a bad defrost thermostat include:

• Excessive frost buildup in the freezer
• The refrigerator not maintaining the correct temperature
• The defrost heater not activating
• The refrigerator running continuously or not running at all

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

This screw is used to secure the handle end cap to the center of the door. The screw size measures 8-18 x 1/2 inches.

This replacement screw secures appliance panels, brackets, and components to the cabinet or chassis. The #8-15 x 1/2 in. size restores a snug, reliable hold when original hardware is missing, stripped, or corroded.

• Fastens panels, brackets, and trim to the appliance cabinet or chassis
• Helps reduce rattling, vibration, or looseness caused by missing/stripped hardware
• Restores proper alignment of parts that have shifted due to loose fasteners
• Size/spec: #8-15 thread, 1/2-inch length; use where this size is specified

• Disconnect power and shut off gas/water supplies before servicing
• Replace one screw at a time to maintain alignment of parts
• Start threads by hand to prevent cross-threading; do not overtighten
• Use a matching driver/bit type for the screw head used in your appliance

This is a Whirlpool refrigerator evaporator. The evaporator is the large, winding piece on the rear of a refrigerator. When touched, these components are extremely hot. Refrigerant is propelled through these by the compressor. The extremely cold refrigerant, coupled with the high temperature of the evaporator tubes, cause a reaction that produces cold air when the refrigerant reaches the freezer or refrigerator area. If the evaporator is faulty, the refrigerator area may continue to remain at temperature, but the freezer portion will stop freezing. Cool temperatures may be maintained, but freezing levels will no longer be met. In some cases, the entire until may cease to produce low temperatures at all. This is an indicator of a completely broken component. This product is intended for use in Whirlpool and Kenmore appliances. It is a genuine OEM product and is sourced exclusively from the manufacturer. This part is only available as an individual component.

Defrost heater melts frost and ice from the refrigerator's evaporator coils so the cooling system can run efficiently. Replacing a failed heater restores proper defrost cycles and helps prevent frost-related cooling issues. What it does:

• Heats the evaporator to melt accumulated frost and ice on the coils.
• Restores normal airflow and consistent temperatures when frost buildup reduces cooling performance.
• Common symptom linkage: visible frost or ice on the evaporator, long or continuous run cycles, or uneven/warmer compartments.
• Works with the defrost thermostat and control to complete the defrost cycle.

• Disconnect power to the appliance before accessing the evaporator or heater — always prioritize safety.
• Handle evaporator fins and the heater element carefully to avoid damage; follow OEM routing and attachment points.
• Verify heater continuity and inspect the defrost thermostat and control before and after replacement; replace any failed defrost components as needed.

This heater clamp secures a heating element in the correct position within the appliance. Proper support keeps the element stable so it operates quietly and melts frost as designed for consistent, reliable performance.

• Holds the heater firmly in place to maintain correct alignment
• Reduces movement and vibration that can cause noise or wear
• Helps promote even frost melt during defrost for steady cooling
• Symptoms of a damaged or missing clamp can include recurring frost/ice buildup, a heater out of position, or rattling from the freezer area

• Disconnect power before servicing; wear cut-resistant gloves
• Access the heater/evaporator by removing the freezer panel as applicable
• Note the original clamp orientation and routing before removal
• Use needle-nose pliers to install; avoid damaging evaporator fins and do not deform the heater—position it exactly as originally placed

A replacement drain pan that captures defrost and condensation water to keep it contained and away from the cabinet and floor. Restores the appliance's normal water-collection path and helps reduce leaks. What it does:

• Collects melting ice and condensation from the evaporator to prevent water from pooling under the appliance.
• Channels collected water toward the drain system so it evaporates or exits as designed.
• Stops common symptoms like puddles or moisture under the unit and musty odors caused by standing water.
• Fits under the evaporator/coil area to restore proper water management.

• Disconnect power to the appliance before service to avoid electrical hazards.
• Remove the required access panels or move the appliance per the manufacturer's guidance to reach the pan.
• Lift out the old pan carefully—it may contain standing water—and position the replacement so the drain outlet and routing match the OEM layout.
• After installation, restore power and check for proper water flow during a defrost cycle; inspect surrounding seals and tubing for proper seating.

This dampener cushions and stabilizes the washer tub during spin cycles to reduce vibration and noise for smoother operation. It replaces worn or damaged suspension dampeners to help restore proper tub balance and quieter performance. What it does:

• Absorbs and dampens tub movement during agitation and spin to reduce vibration and noise.
• Helps maintain proper tub alignment for more even spinning and less wobble.
• Commonly replaced when the washer rocks, thumps, or makes excessive noise during spin.
• Works with the washer's suspension system to protect other components from shock and wear.

• 1 dampener

• Disconnect power and shut off water supply before beginning any repair.
• Access typically requires removing the washer cabinet or front panel; follow OEM service instructions.
• Inspect mounting studs and clips for wear; replace as needed to ensure a secure fit.
