Is there a 30 wide side by side refrigerator?
Yes. 30-inch-wide side-by-side refrigerators exist, but the Whirlpool GC3SHEXNS00 is designed for a 36-inch opening. If you need a true 30-inch-wide side-by-side, you will need a different model; this one will not fit a 30-inch cabinet cutout.
Based on the installation dimensions for this Whirlpool side-by-side refrigerator, plan for:
- Opening width: 36 inches (91.5 cm)
- Door swing clearance: doors should open to at least 150°
- Side-wall clearance: allow about 13 1/4 inches (34 cm) on the freezer side and 16 1/2 inches (42 cm) on the refrigerator side (varies by model)
For the exact cutout and clearance guidance for your kitchen layout, use the GC3SHEXNS00 installation guide.
When you are comparing refrigerators, focus on the cabinet opening and door swing, not just the advertised width.
- Measure the cabinet opening width at the front and back
- Measure depth to nearby walls, islands, and door trim
- Confirm door swing clearance so drawers and bins can pull out
- Verify water line location if you have an ice maker or dispenser
- Check hinge clearance and handle depth in tight spaces
| Feature | 30-inch side-by-side | Whirlpool GC3SHEXNS00 |
|---|---|---|
| Typical cabinet opening needed | 30 inches | 36 inches |
| Fit in a 30-inch opening | Yes | No |
| Door swing planning | Important | Required (150° minimum) |
A refrigerator that is even a few inches too wide will not install safely, and insufficient door clearance can prevent the freezer and fresh food doors from opening far enough to access shelves, bins, and the ice maker.

Where is the filter on my Whirlpool side by side refrigerator?
On the Whirlpool GC3SHEXNS00 side-by-side refrigerator, the water filter is typically installed in the base grille area near the floor (front of the unit). Your GC3SHEXNS00 owner's manual also lists the standard replacement filter as part number 4396710.
- Look at the very bottom front of the refrigerator for the base grille.
- Check for a small filter door or round filter cap you can turn.
- If you see a cap, it may be the refrigerator water filter cap (black) WP2260518B.
- If the filter is not in the grille, check inside the fresh food compartment near the upper-right ceiling area (common on some Whirlpool side-by-side designs).
- Confirm the exact location and removal method in the GC3SHEXNS00 owner's manual.
The GC3SHEXNS00 uses a standard water filter listed as part number 4396710. If you are replacing the cartridge itself, use the model-matched refrigerator water filter EDR3RXD1.
| Item | What it does | When you replace it |
|---|---|---|
| Water filter (4396710) | Reduces contaminants in drinking water and ice | About every 6 months (typical) |
| Filter cap | Locks the filter in place and helps seal the housing | If cracked, stripped, or missing |
A correctly installed filter helps maintain water flow to the dispenser and ice maker, and it helps keep water and ice tasting clean. A loose cap or mis-seated filter can also cause leaks or weak dispensing.
- Dispense a few cups of water after installing a new filter to flush air and carbon fines.
- Check for drips around the filter area for the first few minutes.
- If water flow is still weak, verify the filter is fully seated and the cap is not damaged.
For step-by-step guidance, we recommend how to replace the water filter in a Whirlpool refrigerator.

What is the capacity of the GC3SHEXNS00?
The Whirlpool GC3SHEXNS00 side-by-side refrigerator is a 25 cu. ft. class model; the installation guide lists a 25' (694 L) size option for this platform. For the exact labeled capacity for your unit, confirm it in the GC3SHEXNS00 owner's manual.
The installation guide groups this refrigerator platform into two size classes:
- 23' (654 L)
- 25' (694 L)
- The GC3SHEXNS00 is associated with the 25' size class in the provided documentation excerpts.
| Size class in install guide | Approx. liters | What it means |
|---|---|---|
| 23' | 654 L | Smaller cabinet size option for this design |
| 25' | 694 L | Larger cabinet size option for this design |
Capacity can be listed a few different ways depending on the source:
- Total capacity vs. usable capacity (after shelves, bins, and ice maker)
- Marketing “cu. ft. class” rounding (for example, “25 cu. ft.”)
- Variations by configuration (ice maker installed, door bins, etc.)
Capacity affects food storage planning and also helps when comparing similar Whirlpool refrigerator models or choosing accessories like a water filter and ice maker components.

What size is a Whirlpool side by side refrigerator?
For the Whirlpool GC3SHEXNS00 side-by-side refrigerator, plan on a 36-inch wide cabinet opening and an opening height of about 69 inches (23 cu. ft. class) or about 72 inches (25 cu. ft. class). Use the GC3SHEXNS00 installation guide to match the correct height group and clearances for your setup.
The installation specifications for this Whirlpool side-by-side platform call out a 36-inch opening width and two common opening-height groups based on capacity class.
- Minimum cabinet opening width: 36 in (91.5 cm)
- Opening height (23 cu. ft. class): 69 in (175.3 cm)
- Opening height (25 cu. ft. class): 72 in (182.9 cm)
- Door swing: allow doors to open to at least 150°
- Side-wall clearance for door swing: 13 1/4 in (34 cm) on the freezer side; 16 1/2 in (42 cm) on the refrigerator side
| Measurement you need for planning | Spec to use | What it affects |
|---|---|---|
| Cabinet opening width | 36 in | Whether the refrigerator fits between cabinets |
| Opening height (23 cu. ft. class) | 69 in | Top clearance and leveling range |
| Opening height (25 cu. ft. class) | 72 in | Top clearance and leveling range |
| Side clearance for door swing | 13 1/4 in and 16 1/2 in | Whether doors open fully without hitting a wall |
- Measure width at the top, middle, and bottom of the opening
- Measure height on both sides (floors can slope)
- Confirm depth including baseboards and trim
- Verify door swing space if a wall is next to either door
- Leave room behind for the water line and power cord routing
Correct opening width, height, and door-swing clearance prevent installation problems, help the refrigerator level correctly, and keep the doors sealing properly so the unit cools efficiently.
