KitchenAid KSSC42QMS02 built-in refrigerator Parts

Yes. KitchenAid makes 33-inch wide refrigerators, but your KitchenAid KSSC42QMS02 is a built-in side-by-side model that’s about 42 inches wide (measured trim edge to trim edge), so it is not in the 33-inch class. For built-in sizing and clearances, use the KSSC42QMS02 installation guide.

How this relates to your KSSC42QMS02

KitchenAid’s 33-inch models are typically freestanding refrigerators designed for standard cabinet openings. The KSSC42QMS02 is a built-in platform with different width and installation requirements.

Key points to keep in mind:

• Built-in widths are commonly 36, 42, and 48 inches (by model series).
• Width is measured at the trim, not the cabinet box.
• Door swing and handle clearance can require extra space.
• Built-in units often need anti-tip boards and specific opening dimensions.
• Water supply and electrical placement are part of the install plan.

Quick size comparison

Refrigerator type	Common widths	Typical fit goal
Freestanding (standard-depth/counter-depth)	30, 33, 36 inches	Standard kitchen cutouts
Built-in side-by-side (like KSSC42QMS02)	36, 42, 48 inches	Flush, cabinet-integrated install

Why it matters

If you’re shopping to replace a KSSC42QMS02, a 33-inch refrigerator usually will not fill the opening correctly and can leave gaps, trim issues, or clearance problems. Matching the built-in width and the installation specs helps avoid costly cabinetry changes.

On the KitchenAid KSSC42QMS02, unlock the water dispenser by pressing the UNLOCK button on the dispenser control panel until the lock indicator changes state and the dispenser lever works again. This model uses a dedicated LOCK/UNLOCK control rather than a long press.

Quick steps for model KSSC42QMS02

• Press UNLOCK on the dispenser panel.
• Confirm the lock indicator above the LOCK button is no longer showing the dispenser is locked.
• Test by pressing a glass against the water dispenser lever.
• If it still will not dispense, make sure the freezer door is fully closed.
• If water spurts or flow is weak after unlocking, flush a few minutes of water to clear air.

For the exact button layout and dispenser notes, use the KSSC42QMS02 use & care manual.

If UNLOCK does not restore dispensing

If the dispenser stays inactive after using UNLOCK, the issue is usually not the lock feature itself. Check these common causes:

• No water supply: household shutoff valve is closed or water pressure is low.
• Air in the water line: common after filter service or water line work.
• Frozen water line: can happen if temperatures are set too cold or airflow is restricted.
• Dispenser lever not actuating: a broken lever or retainer can prevent the switch from being pressed.
• Control issue: a dispenser or main control may not be responding.

Helpful parts to inspect (if the lever feels loose or does not “click”)

Symptom	What to check	Example compatible part for this model
Lever moves but does not activate	Lever/retainer alignment or damage	Refrigerator dispenser lever W10856124
Lever hardware not holding correctly	Retainer/clips at the lever pivot	Refrigerator dispenser lever retainer WP2194719

Why it matters

A locked dispenser is meant to prevent accidental dispensing during cleaning or around kids and pets. If the dispenser still will not run after unlocking, troubleshooting the water supply, frozen line conditions, or dispenser lever hardware prevents unnecessary part replacement.

On KitchenAid model KSSC42QMS02, a water dispenser that won’t dispense is most often caused by the dispenser being locked, air in the water line after service, a restricted water filter, a frozen reservoir/line, or a water inlet valve that isn’t opening. Start with the simplest checks first.

Quick checks (no tools)

• Make sure the dispenser is not set to LOCK (this model can disable the dispenser levers).
• Close the freezer door firmly; dispensing can stop if the door switch is not being pressed.
• If you recently changed the filter or shut off water, purge air by dispensing water for several minutes.
• Confirm the household shutoff valve is fully open and the supply line behind the unit is not kinked.
• If water flow is weak or stops, replace the filter and flush the system.

For the exact flushing steps and filter status reset procedure, follow the KSSC42QMS02 use & care manual.

Model-specific issue to watch for: reservoir or line freezing

The KSSC42QMS02 manual notes that if the water dispenser stops working, water in the line may have frozen (often related to very cold settings or a cold meat drawer air duct setting).

• Raise the refrigerator temperature slightly.
• Set the meat drawer temperature control toward COLD.
• Allow 24 hours, then try dispensing again.

Parts that can cause “no water” (when checks don’t fix it)

If the basics look good, these components are common failure points:

• Door switch (dispenser may not run if the control thinks the door is open)
• Water reservoir (can freeze or restrict flow)
• Water inlet valve (may hum/click but not open)

Model-matched parts to consider:

• Refrigerator freeer door switch W11457217
• Refrigerator water reservoir WP2256126

Symptom guide

What you notice	Most likely cause	What we recommend
No sound, no water	Lock on, door switch not made	Unlock; check door closes and switch clicks
Water spurts then stops	Air in line	Purge several minutes
Slow flow	Filter restriction or low supply	Replace filter; verify shutoff fully open
Stops after very cold temps	Reservoir/line freezing	Adjust temps; set meat drawer to COLD

Why it matters

Restoring proper water flow helps prevent ice maker fill problems and avoids repeated strain on the dispenser system when you press the lever.
