KitchenAid KSSS42MHX00 built-in refrigerator Parts

Yes. KitchenAid makes side-by-side refrigerators, and your KitchenAid model KSSS42MHX00 is a built-in side-by-side refrigerator. Side-by-side designs keep the freezer on one side and fresh food on the other, with vertical doors and separate temperature zones.

A side-by-side layout is built for easy access and consistent airflow across both compartments.

• You get full-height freezer and refrigerator sections
• Narrower door swing than many French door models (helpful in tight kitchens)
• Dedicated evaporator airflow helps maintain stable temperatures
• Ice maker and water features are common on this style

Even when the cabinet and sealed system are in good shape, wear items can affect cooling, ice production, and door sealing.

• Ice maker components (ice maker assembly, thermostat, ice mold)
• Defrost system parts (defrost timer, defrost heater, defrost bi-metal)
• Air movement parts (evaporator fan motor, evaporator fan blade)
• Door sealing and alignment parts (door gasket, door hinge)
• Water system tubing (water tube)

These are examples of model-matched parts that commonly relate to side-by-side operation.

If you are troubleshooting cooling airflow or fan noise, we use the same core checks on most KitchenAid side-by-side designs: verify the evaporator fan runs, clear vents, and confirm the door seals are closing evenly.

When a side-by-side refrigerator loses airflow (fan issue) or can’t defrost properly, temperatures drift quickly and you can see frost, warm spots, or poor ice production. Addressing the right system first saves time and prevents unnecessary part swaps.

Water leaking from your KitchenAid KSSS42MHX00 side-by-side refrigerator is usually caused by a clogged or frozen defrost drain, a leaking water supply connection, or a problem in the ice maker or dispenser water tubing. Start by identifying whether the water is inside the fresh food section, under the freezer, or at the back.

• Water only after defrosting or a sheet of ice on the freezer floor: defrost drain is likely clogged or frozen.
• Water near the front: drain pan overflow, door left ajar, or warm air causing heavy condensation.
• Water at the back/bottom: supply line connection or internal water tube leak.
• Leak happens when dispensing water or making ice: tubing, fittings, or ice maker fill circuit.

• Clogged/frozen defrost drain: Clear ice from the drain trough and flush the drain with hot water (a turkey baster works well). Clean debris from the drain opening.
• Cracked or loose water tubing: Inspect the line from the household supply to the cabinet inlet, then the internal tubing to the dispenser and ice maker. If you find a split line, replace the tube.
• Ice maker leak or overfill: Check the ice maker fill area for icicles or a frozen fill cup; a failing ice maker thermostat can contribute to odd cycling.
• Door gasket not sealing: Warm air intrusion creates excess frost and meltwater that can overwhelm the drain.

A small leak can turn into floor damage, recurring ice buildup, and poor cooling if the evaporator area starts icing over. Fixing the root cause also helps your KitchenAid built-in refrigerator run more efficiently.

If your KitchenAid KSSS42MHX00 side-by-side refrigerator isn’t making ice, the most common causes are a blocked or kinked water supply line, the ice maker being turned off, low water pressure, or a failed ice maker component. Start with water flow and simple ice maker checks before replacing parts.

• Confirm the ice maker is switched ON and the shutoff arm is down (not in the “off” position).
• Make sure the freezer is cold enough; most ice makers need the freezer near 0°F to cycle normally.
• Inspect the household water line behind the refrigerator for kinks or pinches; straighten the line and avoid pushing the unit too far back.
• Verify the water shutoff valve is fully open and the supply line is not clogged.
• Dump old or clumped ice and make sure the ice bin is seated correctly.

A weak or interrupted fill will stop ice production. If you recently moved the refrigerator or pushed it back into the cabinet, a pinched line is especially common.

If the basic checks look good, these parts are common culprits for KSSS42MHX00 ice issues:

• Ice maker assembly - refrigerator ice maker by whirlpool 4317943 (won’t cycle, won’t harvest, or won’t fill)
• Refrigerator ice maker thermostat WP627985 (ice maker not advancing through the cycle)
• Refrigerator ice mold WPW10190929 (damaged mold can cause release or harvest problems)

An ice maker depends on steady water flow and correct freezer temperature. Fixing a kinked line or low flow prevents repeat failures and helps avoid leaks, hollow cubes, and slow ice production.

Temperature inconsistency is the most common problem we see on KitchenAid refrigerators like model KSSS42MHX00; it shows up as warm fresh-food temps, soft ice cream, or frequent thawing and refreezing. The usual causes are airflow issues, a failing evaporator fan, or a defrost system problem.

• Confirm the doors seal fully and nothing is blocking the vents.
• Set the controls to normal (avoid the warmest setting) and give temps 24 hours to stabilize.
• Listen for the evaporator fan in the freezer; it should run when the compressor is running.
• Look for heavy frost on the freezer back wall (a strong sign of a defrost problem).
• Check for water leaks or puddles that can indicate a clogged drain or water line issue.

When temperatures swing, food quality drops fast and the compressor can run longer than normal. Fixing airflow or defrost problems early helps your KitchenAid built-in refrigerator cool evenly and avoid repeat icing or warm spots.
