How many cubic feet is a KitchenAid KSRG25FKST18 refrigerator?
The KitchenAid KSRG25FKST18 side-by-side refrigerator is typically listed at about 25.3 cubic feet of total capacity. That number represents combined fresh food and freezer space; usable space can feel slightly lower once shelves, bins, and the ice system are in place.
What “25.3 cubic feet” means in real use
Capacity is a volume rating, not a promise of how much you can physically stack.
- Total capacity includes both compartments (refrigerator + freezer)
- Shelves, drawers, and the ice maker reduce usable packing space
- Door bins add storage but do not always fit large containers well
- Airflow channels must stay open for even cooling
- Overpacking can cause warm spots and frost issues
Quick capacity reference
| Capacity range | Typical fit | Best for |
|---|---|---|
| 20 to 22 cu. ft. | Smaller side-by-sides | 1 to 3 people |
| 23 to 26 cu. ft. | Full-size side-by-sides | 3 to 5 people |
| 27+ cu. ft. | Extra-large units | Large households, bulk storage |
Why it matters
Knowing the cubic feet helps when you are comparing replacement refrigerators, planning kitchen space, or deciding whether storage issues are caused by layout problems (bins, ice bucket, shelves) versus the refrigerator being undersized.

- Refrigerator ice maker 2198597 (ice production hardware inside the freezer)
- Refrigerator ice dispenser door WP2180353 (dispenser flap that helps prevent clumping)

What is the most common problem with KitchenAid refrigerators?
For KitchenAid side-by-side refrigerators like model KSRG25FKST18, the most common issues we see are ice maker and water dispensing problems (no ice, slow ice, leaking) and cooling/temperature complaints caused by airflow restrictions, frost buildup, or a failing fan or control component. Using the right replacement parts, such as the refrigerator ice maker 2198597 or refrigerator inlet valve W10408179, typically resolves the most frequent failures.
Most common symptoms customers report
- Ice maker not making ice or making hollow/small cubes
- Water dispenser slow, sputtering, or not dispensing
- Freezer cold but fresh food section warm (airflow problem)
- Frost buildup on the freezer back wall (defrost problem)
- Unusual fan noise or intermittent cooling
Quick checks that solve many “common problems”
- Confirm temperatures: set freezer near 0°F and refrigerator near 37°F.
- Check airflow: do not block vents with food packages.
- Inspect for frost: heavy frost on the freezer rear panel points to a defrost system issue.
- Verify water supply: make sure the shutoff valve is fully open and the supply line is not kinked.
- Replace the water filter on schedule: a clogged filter can reduce water flow and affect ice production; follow how to replace the water filter in a KitchenAid refrigerator.
Parts that commonly fix the most frequent failures
| Problem area | What you notice | Common fix on KSRG25FKST18 |
|---|---|---|
| Ice maker system | No ice, slow ice, jammed cubes | Replace refrigerator ice maker 2198597 or inspect the ice path and dispenser door |
| Water supply | No water to dispenser/ice maker, leaking at back | Replace refrigerator inlet valve W10408179 |
| Water filtration | Slow water, small cubes | Replace refrigerator filter EDR5RXD1 or check refrigerator water filter housing WP2186443 |
| Defrost system | Frost buildup, warm fridge section | Check refrigerator defrost bi-metal thermostat WPW10225581 and refrigerator heater WP2323198 |
| Air circulation | Warm temps, fan noise | Diagnose fan issues and consider refrigerator evaporator fan motor WP2315549 (see how to fix your evaporator cooling fan) |
Why it matters
Ice maker and temperature problems often share the same root causes: restricted airflow, weak water flow, or frost buildup. Catching these early helps prevent food spoilage, reduces compressor run time, and keeps your KitchenAid refrigerator running efficiently.

How do I find the model number on my KSRG25FKST18?
For a KitchenAid side-by-side refrigerator like model KSRG25FKST18, the model number is printed on the appliance’s rating label (model and serial tag). We use that exact model number to match the correct diagrams and replacement parts.
Where to look on a KitchenAid side-by-side refrigerator
Check these common label locations (in order):
- Inside the fresh food compartment on the side wall (often right wall)
- On the ceiling of the fresh food compartment near the light housing
- Along the door frame (hinge side) when you open the refrigerator door
- Behind the toe grille or lower kickplate area (less common)
- Inside the freezer compartment on a side wall (occasionally)
What the label should show
The tag typically includes:
- Model number (example: KSRG25FKST18)
- Serial number (used for production date and service history)
- Electrical ratings (voltage and amps)
- Refrigerant information (type and charge)
Why it matters
KitchenAid model numbers can look similar across different production runs; one character difference can change the correct water filter, ice maker, inlet valve, or door gasket. Using the exact model number helps ensure the part fits and the repair goes smoothly.
Quick part-matching examples for this model
Here are a few parts that are model-matched for KSRG25FKST18 (use these names and IDs when comparing):
| System | Example part on this model | What it affects |
|---|---|---|
| Water filtration | Refrigerator filter EDR5RXD1 | Water taste, flow, ice quality |
| Ice and water | Refrigerator inlet valve W10408179 | No water dispensing, no ice fill |
| Ice maker | Refrigerator ice maker 2198597 | No ice production |
