KitchenAid KSSO48QMB03 built-in refrigerator Parts

KitchenAid “Superba” is a product line name, not one single size; capacity depends on the exact model. For your KitchenAid built-in refrigerator model KSSO48QMB03, the most accurate cubic-feet capacity is listed in the specifications section of the KSSO48QMB03 owner's manual.

How to get the right cubic-feet number (fast)

To avoid mixing up Superba models (freestanding vs built-in), match the capacity to the model tag inside the refrigerator, then confirm it in the manual.

• Find the model/serial tag inside the fresh food compartment (often on a side wall or ceiling area)
• Confirm the model number is KSSO48QMB03
• Check the “Specifications” or “Product data” section in the KSSO48QMB03 owner's manual
• If you are comparing refrigerators, note that built-in units often list capacity differently than freestanding units
• Use the cabinet width (this model family includes 36, 42, and 48-inch versions) as a cross-check

Built-in size context for KSSO48QMB03

Your installation guide shows this is a 48-inch built-in platform (trim edge to trim edge). That helps confirm you are looking at the correct built-in series when comparing “Superba” capacities.

Built-in series width	What it helps confirm
36-inch	Different platform and capacity range
42-inch	Different platform and capacity range
48-inch (KSSO48QMB03 family)	Matches the 48-inch built-in configuration

Why it matters

Cubic feet affects food storage planning, airflow loading, and expectations for ice maker and cooling performance. Using the exact KSSO48QMB03 spec prevents ordering the wrong shelves, door bins, or door panels for a different “Superba” model.

Yes, 30-inch-wide side-by-side refrigerators exist, but the KitchenAid KSSO48QMB03 is a built-in side-by-side model in the 48-inch class, not a 30-inch unit. If you are planning cabinetry, use the clearances and panel requirements in the KSSO48QMB03 installation guide to size your opening correctly.

What “30-inch wide” usually means

Most shoppers mean a refrigerator that fits a 30-inch cabinet opening (common in smaller kitchens and condos). In practice, you will see:

• 30-inch class: typically about 29 1/2 to 30 inches wide overall
• Counter-depth vs. standard-depth: depth and door swing can change the real space needed
• Side-by-side vs. French door: 30-inch side-by-side options are less common than 30-inch top-freezer or French door models
• Built-in vs. freestanding: built-in units (like KSSO48QMB03) are usually wider and require specific installation clearances

How KSSO48QMB03 sizing affects your kitchen plan

The KSSO48QMB03 is part of KitchenAid’s built-in side-by-side “Overlay Series” family (KSSO36QMB, KSSO42QMB, KSSO48QMB). That means it is designed for custom overlay panels and needs proper side clearance for door swing.

Key planning points we follow from the installation guidance:

• Allow at least 4 1/2 inches between the refrigerator side and a corner wall for door swing
• Plan for panel and handle thickness, which can increase clearance needs
• Overlay installations require custom panels, handles, and standoffs
• Keep doors secured during installation and use two or more people to move the unit

Quick comparison: 30-inch side-by-side vs. KSSO48QMB03

Feature	30-inch side-by-side (typical)	KitchenAid KSSO48QMB03
Intended opening	30-inch cabinet space	48-inch built-in opening class
Installation type	Usually freestanding	Built-in, overlay panel capable
Panel-ready	Sometimes	Yes (overlay series design)
Clearance planning	Important	Critical (door swing and panels)

Why it matters

Choosing by “width” alone can lead to fit problems. Door swing, corner clearance, and custom panel thickness often determine whether the refrigerator actually works in your layout, especially with built-in models like KSSO48QMB03.

Most standard side-by-side refrigerators measure about 30 to 36 inches wide, 67 to 70 inches tall, and 29 to 35 inches deep. For the built-in KitchenAid KSSO48QMB03, the “standard size” idea is less useful because installation is driven by cabinetry cutout, door swing, and required clearances shown in the KSSO48QMB03 installation guide.

Typical side-by-side size ranges (quick reference)

Measurement	Typical range (freestanding side-by-side)	What matters most for KSSO48QMB03
Width	30 to 36 in.	Cabinet opening and trim fit
Height	67 to 70 in.	Cabinet height and top clearance
Depth	29 to 35 in.	Door and handle projection, door swing

Built-in sizing and clearance checks for KSSO48QMB03

Built-in models are planned around the opening and how the doors move. When you measure, focus on these items:

• Door swing to 90 degrees: confirm the doors can open fully without hitting cabinets or walls.
• Side clearance at corners: allow at least 4 1/2 inches between the side of the refrigerator and a corner wall (more if using thicker custom panels or custom handles).
• Overlay panel clearance: allow 1/2 inch clearance between an overlay panel and cabinetry.
• Panel thickness: custom side panels should be at least 1/2 inch thick to help prevent warping.
• Depth planning: if the opening depth is 25 inches or more, a rear support board is commonly used for panel support.

How we recommend measuring (so the fridge fits the first time)

• Measure the cabinet opening width, height, and depth in multiple spots.
• Measure from the back wall to the front face of cabinetry (this affects how far the refrigerator and doors will project).
• Confirm baseboards and trim will not interfere with the side trim or door swing.
• Plan for handle depth if you are using extended or custom handles.

Why it matters

A side-by-side can be “standard size” and still not fit correctly if the doors cannot open to 90 degrees or if the installation lacks the required corner and panel clearances. Built-in models like the KSSO48QMB03 are especially sensitive to these details.
