KitchenAid KSSP42QTS00 built-in refrigerator Parts

For your KitchenAid built-in refrigerator model KSSP42QTS00, we determine the age by reading the serial number on the model and serial tag, then decoding the date code embedded in that serial. The exact format varies by production era, so we use the decoding method shown in your owner's manual.

Where to find the serial number on KSSP42QTS00

On this KitchenAid built-in side-by-side, the model and serial number label is on the refrigerator itself (not on the packaging). Use the label to record both numbers before you start decoding.

• Open the refrigerator compartment and look along the inside cabinet walls
• Check near the top side walls or ceiling area inside the fresh food section
• Check behind the crisper drawers area if you do not see it up top
• Write down the full serial number exactly as shown (letters and numbers)

How serial number date codes typically work

KitchenAid serial formats have changed over time. Most systems include a year indicator and a week (or production sequence) indicator.

• One character indicates the production year (often a letter)
• One or two characters indicate the production week
• Some older formats use digits where the last two digits represent the year
• Some formats repeat on a cycle, so the same year code can map to more than one calendar year

Quick decode checklist

• Confirm you are reading the serial number (not the model number)
• Look for a letter that could represent the year
• Look for 2 digits that could represent the week (01 to 52)
• If the code repeats, use the refrigerator’s approximate age and styling to pick the correct decade

Why it matters

Knowing the build date helps us match the correct KitchenAid parts and revisions for KSSP42QTS00, especially for common service items like the water filter system, controls, and door switches.

Holiday Mode on your KitchenAid KSSP42QTS00 is a vacation and observance feature that keeps your temperature set points the same while turning off the interior lights and disabling the ice maker (and, on some models, disabling the dispenser levers and lights). See the KSSP42QTS00 owner's manual for the exact button steps for your control and dispenser panels.

What Holiday Mode changes (and what it does not)

When Holiday Mode is on, we expect these behaviors:

• Refrigerator and freezer temperature set points stay unchanged
• Interior lights turn off
• Ice maker is disabled
• On some models, dispenser levers are disabled and dispenser lights turn off
• You should exit Holiday Mode when you no longer need it for best overall operation

Quick behavior summary

Feature	In Holiday Mode	Why you notice it
Temperature set points	Stay the same	Food stays at your chosen temps
Ice maker	Off/disabled	No new ice production
Interior lights	Off	Lights do not come on when doors open
Dispenser (some models)	Disabled, display shows “HOL”	No water/ice dispensing from the lever

How to turn Holiday Mode on and off (KSSP42QTS00)

Holiday Mode can require activation in two places depending on your exact configuration.

• Control panel: press HOLIDAY MODE to turn it on; press again to turn it off.
• Dispenser panel (some models): press and hold ICE + LIGHT + LOCKOUT together for 3 seconds to turn it on; repeat for 3 seconds to turn it off.

Important note about Max Cool

If Max Cool was selected before Holiday Mode, the refrigerator can temporarily hold the Max Cool set points (commonly 34°F fresh food and -5°F freezer) until Max Cool times out; Holiday Mode still keeps the lights and ice maker off until you turn Holiday Mode off.

Why it matters

Holiday Mode is designed for travel and for situations where you want lights and ice production off without changing your temperature settings. That helps prevent unnecessary ice buildup and keeps the refrigerator operating normally while you are away.

On your KitchenAid built-in refrigerator model KSSP42QTS00, the model number is printed on the appliance’s model and serial number label. We use that full model number to match the correct parts list, diagrams, and documentation for your exact refrigerator.

Where to find the model number label

Check these common locations on built-in side-by-side refrigerators:

• Inside the fresh food compartment on a side wall near the crisper area
• Along the cabinet frame near the top, behind the refrigerator door
• Inside the freezer compartment on a side wall
• Behind the toe grille or lower kickplate area (on some built-in designs)
• On the cabinet frame near the hinge side (door open)

For the exact label location and how it’s shown for this model, use the KSSP42QTS00 owner's manual.

How to “read” the model number for parts matching

For ordering parts and looking up diagrams, the most important rule is to use the entire model number exactly as printed.

• Copy it character-for-character (letters and numbers)
• Keep any suffixes (for example, “00”) because they can change the parts used
• Use the model number (not the serial number) to find parts like a water filter, door gasket, or control board

Quick guide

What you see on the label	What it’s used for	Example for this unit
Model number	Identifies the exact design and parts	KSSP42QTS00
Serial number	Identifies the production unit/date	Varies by unit

Why it matters

KitchenAid built-in refrigerators often have multiple versions that look similar but use different components (controls, sensors, door parts, and water system parts). Using KSSP42QTS00 prevents ordering the wrong part and avoids fit or wiring mismatches.

The most common KitchenAid refrigerator problems are cooling complaints (warm fridge or freezer), ice maker or water dispenser issues, and water leaks. On the KitchenAid KSSP42QTS00, these symptoms most often trace back to airflow problems, defrost/drain issues, or water supply components; use the owner's manual for model-specific operating and care checks.

Most common symptoms and what usually causes them

• Warm refrigerator section: restricted airflow, evaporator fan issue, or a temperature sensor problem
• Frost buildup on the back wall or poor cooling: defrost system trouble (heater circuit, defrost thermostat/bi-metal)
• No ice or slow ice production: water supply restriction, filter blockage, or inlet valve problem
• Water leaking inside or under the unit: clogged/iced drain, loose water tube fitting, or valve seepage
• Unusual noises: fan blade rubbing ice, condenser fan noise, or vibration from panels/trim

Quick checks we recommend before replacing parts

1. Confirm controls are set correctly and doors seal fully.
2. Check for heavy frost in the freezer (points to a defrost/airflow issue).
3. If water flow is weak, replace the filter and purge air from the dispenser.
4. Inspect for leaks at tubing connections and the inlet valve area.
5. Clean condenser coils and verify the condenser fan runs when the compressor runs.

Common parts that match these problems (KSSP42QTS00)

Symptom	Likely system	Example part on this model
Weak water flow, bad taste/odor	Filtration	Refrigerator water filter EDR3RXD1
Frost buildup, warm temps	Defrost	Refrigerator defrost bi-metal WPW10225581
No water to dispenser/ice maker	Water supply	Refrigerator inlet valve W10876668
Noisy or warm fridge section	Air circulation	Refrigerator evaporator fan blade WP2169142

Why it matters

Cooling, ice, and leak complaints usually share one root cause: airflow or water flow is being restricted. Fixing the restriction early helps protect food temperatures, reduces frost buildup, and prevents recurring puddles.

Most KitchenAid refrigerators last about 14 to 17 years with normal household use and basic maintenance. For your KitchenAid KSSP42QTS00 built-in side-by-side refrigerator, keeping airflow clear and temperatures stable is the biggest factor in reaching that typical lifespan.

What affects lifespan the most

• Condenser coil cleanliness (dust buildup makes the sealed system work harder)
• Door seal condition (air leaks cause longer run times and temperature swings)
• Stable temperatures (avoid frequent warm-ups from propped doors or overloading)
• Good airflow inside the cabinet (don’t block vents with food packages)
• Water system upkeep if equipped (replace filters on schedule to maintain flow)

Typical lifespan ranges (what we see most often)

Refrigerator type	Typical lifespan	Notes
Built-in refrigerator (like KSSP42QTS00)	14 to 17 years	Often lasts longer when coils and seals are maintained
Standard freestanding refrigerator	10 to 15 years	More variation by usage and environment

Maintenance checklist that helps you reach the average

• Vacuum and brush the condenser area regularly (frequency depends on pets and dust)
• Confirm doors close and seal evenly; correct sagging or misalignment early
• Keep freezer around 0°F and fresh food around 37°F for balanced run time
• Replace the water filter when flow drops or taste changes; use the correct filter style
• Address unusual noises quickly (fan blade rubbing, clicking relays, or buzzing)

Why it matters

A refrigerator usually fails early from heat stress (dirty condenser, restricted airflow) or air leaks (worn gaskets). Reducing run time and keeping temperatures steady protects major components like the compressor and evaporator.

For model-specific care and settings, follow the maintenance guidance in the KSSP42QTS00 owner's manual.
