KitchenAid KSSP42QMS01 built-in refrigerator Parts

The KitchenAid built-in refrigerator model KSSP42QMS01 is a 42-inch class side-by-side unit. For the exact overall dimensions (width, height, depth, and required clearances), use the specifications section in the owner's manual.

What “big” usually means for this model

When customers ask about size, we typically look at these measurements:

• Overall width (cabinet and door)
• Overall height (to top of cabinet or hinge cover)
• Overall depth (with and without handles)
• Cutout opening (built-in cavity size)
• Clearances (door swing, ventilation, and service access)

Typical built-in 42-inch side-by-side sizing (quick guide)

These are common ranges for 42-inch class built-in refrigerators; confirm your exact numbers in the manual before ordering panels or modifying cabinetry.

Measurement	Typical range for 42-inch class built-ins	Why it matters
Width	~41 1/2 to 42 inches	Fit in the cutout and align with surrounding cabinets
Height	~83 to 84 inches	Matches tall cabinet openings and trim
Depth	~24 to 27 inches (cabinet), deeper with doors/handles	Determines how far the unit projects past cabinetry

How to measure your refrigerator correctly

Use a tape measure and record to the nearest 1/8 inch.

• Measure width at the widest point (often the hinge side or trim)
• Measure height from floor to the highest point (leveling legs can change this)
• Measure depth from the back to the front edge of the door, then again to the front of the handle
• If it is installed, also measure the cutout opening and note any trim or panels

Why it matters

Built-in refrigerators like the KSSP42QMS01 rely on correct cutout sizing and airflow. Getting the exact width, height, depth, and clearance requirements right helps prevent door interference, poor cooling from restricted ventilation, and costly cabinet rework.

If your KitchenAid KSSP42QMS01 is not getting cold, the most common causes are blocked airflow, doors being opened too often, or temperature controls set incorrectly. Start by confirming the set points (freezer: -5°F to 6°F; refrigerator: 34°F to 46°F) in the owner's manual, then check for anything preventing cold air from circulating.

Quick checks we recommend first

• Make sure air vents in both compartments are not blocked by food packages.
• Confirm the doors close fully and are not being held open by bins or shelves.
• Verify the temperature set points; change only 1°F at a time and wait 24 hours between adjustments.
• If your model has digital controls, turn the unit OFF then ON to reset the controls.
• After adding a large amount of food, allow several hours for temperatures to recover.

Temperature settings for KSSP42QMS01

Control	Normal set point range	What to do if too warm
Freezer	-5°F to 6°F	Set 1°F colder; wait 24 hours
Refrigerator	34°F to 46°F	Set 1°F colder; wait 24 hours

Airflow and cooling system issues to watch for

Good cooling depends on steady airflow from the freezer to the fresh food section.

• Warm refrigerator, colder freezer: often points to blocked vents or an airflow problem.
• No fan sound, weak airflow: the evaporator fan area may need attention; see how to fix your evaporator cooling fan.
• Temperatures drift or swing: a sensor issue is possible; the refrigerator thermistor WP2188820 is one component involved in temperature sensing.

Why it matters

When airflow is restricted or controls are mis-set, the refrigerator can run longer, food can warm into unsafe ranges, and frost or moisture problems can increase. Correct set points and clear vents usually restore normal cooling without replacing major parts.

The most common KitchenAid refrigerator problems are cooling performance issues and ice maker or dispenser troubles. On the KitchenAid KSSP42QMS01 built-in side-by-side, these symptoms are often tied to airflow (evaporator fan), temperature sensing, or water supply and filtration.

Most common symptoms customers notice

• Refrigerator section too warm or temperatures swing
• Freezer too warm or heavy frost buildup
• Ice maker slow, no ice, or small/hollow cubes
• Dispenser won’t dispense ice or water consistently
• Unusual fan noise from the freezer area
• Water leaking or puddles near the unit

Quick checks that fix many “common problems”

Start with these basics before replacing parts:

• Confirm controls are set to normal temps (about 37°F fresh food, 0°F freezer)
• Clean condenser coils and ensure the grille area has good airflow
• Make sure doors seal fully and aren’t held open by bins or food packages
• If water or ice is weak, replace the water filter and flush several gallons
• If the freezer is frosty, check for blocked vents and signs of a defrost drain issue

Parts that commonly relate to these issues (for KSSP42QMS01)

Symptom	Common area	Example part on this model
Warm temps, poor airflow, fan noise	Evaporator airflow	Refrigerator evaporator fan blade WP2169142
Temps fluctuate or run too cold/warm	Temperature sensing	Refrigerator thermistor WP2188820
Weak water flow, bad taste, ice issues	Filtration and water flow	Refrigerator filter EDR5RXD1

Why it matters

Cooling and ice maker complaints often share the same root causes: restricted airflow, inaccurate temperature feedback, or restricted water flow. Fixing the underlying cause protects food quality, improves ice production, and reduces strain on sealed system components.

To reset your KitchenAid KSSP42QMS01 side-by-side built-in refrigerator, we recommend doing a simple power reset: turn the unit OFF then ON again at the controls, or cycle power to reboot the control system. This often clears minor dispenser glitches and temporary control errors.

Quick reset options (most common)

• Control reset (digital controls): turn the refrigerator OFF, wait about 30 seconds, then turn it ON.
• Power cycle reset: unplug the refrigerator (or switch the circuit breaker OFF), wait 2 to 5 minutes, then restore power.
• Master Alarm Reset (for alarm conditions): press the POWER (ON/OFF) key twice, or turn power OFF and ON again.
• Over Temperature alarm: press OVER TEMPERATURE RESET to silence the alarm; press it a second time to turn off the indicator light (once temperatures are back to normal).

Step-by-step: power cycle reset (best for dispenser or “glitchy” behavior)

1. If possible, set the controls to OFF.
2. Unplug the refrigerator or turn the breaker OFF.
3. Wait 2 to 5 minutes (this lets the control board fully discharge).
4. Restore power.
5. Turn the controls ON and allow 24 hours for temperatures to stabilize.

What a reset can and cannot fix

Symptom	Reset helps most when	If it comes back quickly, check
Ice or water dispenser not responding	Control is temporarily “stuck”	Filter restriction, dispenser switch, door/ice chute issues
Over Temperature alarm	Temp has returned to normal	Door left open, airflow blocked, heavy warm load
Not cooling after a power event	Controls need reboot	Air vents blocked, evaporator fan issue, sealed system problem

Why it matters

A reset restores normal control logic after a power interruption or minor electronic fault. If the refrigerator is still not cooling after a reset, the issue is usually airflow, temperature sensing, or a component problem rather than a control “glitch.”

Helpful references for this model

• Use the control and alarm reset steps exactly as shown in the owner's manual.
• If water flow is weak or tastes off, follow how to replace the water filter in a KitchenAid refrigerator and confirm you are using the correct filter for KSSP42QMS01, such as refrigerator filter EDR5RXD1.
