KitchenAid KSSP42QMS00 built-in refrigerator Parts

Yes. KitchenAid makes 33-inch wide refrigerators in several styles (commonly French door and bottom-freezer). Your KitchenAid KSSP42QMS00 is a built-in side-by-side model, which is typically wider than 33 inches, so a 33-inch unit is usually a different product line than this model.

How to confirm fit in your kitchen

Use these checks before you shop so the new refrigerator fits the cabinet opening and connects correctly.

• Measure the cabinet opening width at the front and back (walls are often not perfectly square)
• Confirm required clearance for door swing and handles
• Check depth needs (standard depth vs counter-depth) and ventilation space
• Verify water line location if you want an ice maker or water dispenser
• Compare electrical requirements and outlet location

For built-in installation requirements and clearances similar to your current unit, use the KSSP42QMS00 installation guide.

33-inch vs built-in side-by-side: what changes

A 33-inch wide refrigerator is usually a freestanding model; built-in side-by-side units like the KSSP42QMS00 are designed for a built-in enclosure and often use different ventilation and trim.

Feature	33-inch wide freestanding	Built-in side-by-side (like KSSP42QMS00)
Typical width	33 inches	Often wider than 33 inches
Installation	Slides into space with clearance	Fits a built-in opening with specific venting
Depth options	Standard or counter-depth	Built-in depth profile
Service parts	Model-specific	Model-specific

Why it matters

Width is only one part of fit. Built-in refrigerators often require specific airflow, cabinet clearances, and water line routing. Matching those requirements prevents door alignment issues, poor cooling performance, and installation headaches.

To take a KitchenAid built-in refrigerator model KSSP42QMS00 out of demo mode, press and hold the Refrigerator and Freezer temperature buttons at the same time for about 3 to 5 seconds until the display changes and cooling starts.

How to confirm it is really in demo mode

Demo mode usually looks “normal” because lights and the dispenser can still work, but the sealed system will not cool.

Check for these common signs:

• Interior lights work, but temperatures stay warm
• Fans and compressor do not run (or run very little)
• Controls respond, but the unit never reaches set temps
• “Cooling Off” or a similar indicator is shown (wording varies by control style)

Step-by-step: exiting demo mode

Use this quick process on KSSP42QMS00:

• Close both doors so the controls are stable
• Press Refrigerator and Freezer temp buttons together
• Hold 3 to 5 seconds
• Release when the indicator changes or cooling turns on
• Wait 5 to 10 minutes to hear normal operation (fans/compressor)

If the display does not change, restore power for 1 minute and try again.

What to do if it still will not cool

If you exit demo mode and the refrigerator still does not cool, focus on airflow and control inputs first.

• Make sure vents are not blocked by food packages
• Confirm doors are sealing fully (no gaps)
• Verify the condenser area is clean and not overheating
• Listen for the evaporator fan; a failed fan can stop proper cooling

Quick symptom guide

Symptom after demo mode is off	Most likely area to check	Example part on this model
Freezer cold, fresh food warm	Airflow/evaporator fan	Refrigerator evaporator fan blade WP2169142
Temps swing up and down	Temperature sensing	Refrigerator thermistor WP2188819
Frost buildup, warm temps	Defrost system	Refrigerator defrost bi-metal WPW10225581

Why it matters

Demo mode is designed for showroom display; it disables cooling. Turning it off restores normal compressor and fan operation so the refrigerator can reach safe food temperatures.

If your KitchenAid built-in refrigerator model KSSP42QMS00 won’t dispense water, the most common causes are a closed supply valve, a kinked or frozen water line, a clogged filter, or a dispenser-side switch or control issue. Start with the water supply and filter checks first.

Quick checks we recommend first

• Confirm the household water shutoff valve is fully open.
• Make sure the water line behind the refrigerator is not kinked, pinched, or crushed.
• Dispense water for 2 to 3 minutes (in intervals) to purge air after any filter or plumbing work.
• Check for a frozen reservoir or line (often happens if the fresh food section is set too cold).
• Verify the dispenser lever moves normally and is not physically blocked.

Step-by-step troubleshooting (most likely to least likely)

1. Water supply problem: Low house water pressure or a partially closed valve can stop dispensing.
2. Filter restriction: A clogged or incorrectly seated filter can reduce flow to zero. Follow the steps in how to replace the water filter in a KitchenAid refrigerator.
3. Frozen internal water path: If the reservoir line freezes, you may hear the valve hum but get no water.
4. Dispenser switch issue: If the light works but the dispenser does nothing, a door switch or light switch can affect dispenser operation on some designs. For switch-related symptoms, check the refrigerator light switch W11384469.
5. Control or wiring issue: If multiple dispenser functions fail, the electronic control may be involved.

What to listen for (fast diagnosis)

What happens when you press the dispenser?	What it usually means	What to do next
No sound at all	Switch/control not sending power	Check door switch and dispenser lever action
Humming sound but no water	Valve energized but no flow	Check supply valve, frozen line, filter restriction
Weak flow	Partial restriction	Replace filter, check kinks, confirm pressure

Why it matters

A no-water condition is usually a simple flow restriction, but it can also lead to ice maker problems and can strain the water inlet valve if it keeps trying to open against a blockage.

Installation details that help

Use the KSSP42QMS00 installation guide to confirm the correct water supply hookup, routing, and shutoff valve location for your built-in installation.
