How can I tell how many cubic feet my Whirlpool refrigerator is?
For your Whirlpool WRT108FFDB03 top-mount refrigerator, the most reliable way to confirm cubic feet is to look up the model’s published capacity by model number. If you need a quick estimate, we can calculate interior volume by measuring usable space and converting cubic inches to cubic feet.
- Check the model/serial tag inside the fresh food section and confirm the model is WRT108FFDB03.
- Use a model-based lookup first; it accounts for liner shape, shelves, and air channels.
- If you cannot access a lookup, measure and calculate an estimate (steps below).
- If you are comparing similar units, remember top-mount capacities commonly fall in the mid-teens to low-20s cubic feet.
- Empty the section you are measuring (refrigerator and freezer are usually calculated separately).
- Measure usable interior:
- Width (inches)
- Height (inches)
- Depth (inches) (do not include door bins)
- Multiply:
width × height × depth = cubic inches. - Convert:
cubic inches ÷ 1,728 = cubic feet.
| What you have | What it means |
|---|---|
| Cubic inches | Raw measured volume |
| Divide by 1,728 | Converts to cubic feet |
| Usable measurements | Better real-world estimate than measuring to the door gasket |
- Shelving, drawers, and air ducts reduce usable space.
- Rounded corners and the evaporator cover reduce interior volume.
- Freezer and refrigerator sections are often combined for the advertised total.
If doors do not seal well, frost and temperature swings can reduce usable storage space over time. For sealing issues, we often see customers replace the refrigerator door gasket (white) W10861499.
Knowing cubic feet helps us match the right replacement shelves, bins, and accessories, and it also helps when comparing a replacement refrigerator to your Whirlpool WRT108FFDB03.

How to read Whirlpool model numbers?
Whirlpool model numbers identify the product type, size/series, feature set, and the engineering revision; for your top-mount refrigerator, WRT108FFDB03 is the full model number we use to match the correct parts and diagrams. The most important rule is to copy the model number exactly as shown on the rating label.
Whirlpool model numbers are built in chunks. While the exact meaning can vary by product line, this pattern is common for refrigerators like WRT108FFDB03:
- Prefix letters (example: WRT) indicate the refrigerator platform or style (often top-mount).
- Middle digits (example: 108) typically relate to series and capacity class.
- Feature letters (example: FFDB) often indicate finish, door style, or feature package.
- Trailing revision digits (example: 03) indicate an engineering change or revision.
On most Whirlpool top-mount refrigerators, the rating label is found in one of these spots:
- Inside the fresh food compartment on a side wall
- Along the ceiling of the fresh food compartment
- Behind the crisper drawers on an interior wall
- On the cabinet frame near the door opening (hinge side)
| Item | What it tells us | When you need it |
|---|---|---|
| Model number (example: WRT108FFDB03) | Exact design and parts fit | Always, before ordering parts |
| Serial number | Production date and factory info | Helpful for service history and some part changes |
Even one character off can point to a different door gasket, control, or fan setup. When you are troubleshooting cooling or noise issues, matching the model number helps us recommend the right repair path and parts such as the refrigerator evaporator fan motor WP2315539.
- Use the full model number, including the last two digits (for example, 03)
- Do not use a similar-looking model from the door sticker or sales receipt
- Write down the model number first, then take a photo of the rating label
- If ordering a gasket or door part, double-check color and door location (fresh food vs. freezer)

What is the most common problem with a Whirlpool refrigerator?
The most common Whirlpool refrigerator problem is a cooling issue (warm fridge, soft ice, or thawing freezer). On the Whirlpool WRT108FFDB03 top-mount refrigerator, the most frequent causes are airflow restrictions (frost buildup, blocked vents), dirty condenser coils, or a failing evaporator fan that cannot circulate cold air.
- Confirm the temperature controls were not bumped (give changes 24 hours to stabilize).
- Make sure food packages are not blocking air vents in the freezer or fresh-food section.
- Listen for the evaporator fan running when the compressor is on (often a steady fan sound).
- Check for heavy frost on the freezer back wall (points to a defrost problem).
- Clean condenser coils and the area around the condenser fan (if equipped).
- Verify the doors close fully and the gaskets seal all the way around.
| Symptom | Most likely cause | What to do next |
|---|---|---|
| Freezer cold, fridge warm | Poor airflow from freezer to fridge | Clear vents; check evaporator fan operation |
| Both sections warm | Dirty coils, sealed-system issue, or control problem | Clean coils; if no improvement, schedule service |
| Loud buzzing or grinding in freezer | Fan blade hitting ice or failing motor | Inspect fan area; replace fan parts if damaged |
| Water under fridge or inside fridge | Defrost drain issue | Clear drain and check for ice blockage |
If the fan is not running, is noisy, or airflow is weak, these model-matched parts are common fixes:
- Refrigerator evaporator fan motor WP2315539
- Refrigerator evaporator fan blade WP2163777
- Thermistor, refrigerator W11438736
Cooling problems usually start as an airflow or maintenance issue, but they can quickly lead to food spoilage and extra compressor run time. Catching a weak evaporator fan, a bad door seal, or dirty coils early helps the WRT108FFDB03 cool evenly and run more efficiently.

What's the average lifespan of a Whirlpool refrigerator?
Most Whirlpool refrigerators, including the Whirlpool WRT108FFDB03 top-mount style, typically last 10 to 18 years. In our experience, units that get basic upkeep (good airflow, clean condenser area, tight door seals) land closer to the high end of that range.
A refrigerator’s life is mostly driven by compressor run time, heat removal, and how well the cabinet stays sealed.
- Maintenance: Dusty condenser areas make the compressor work harder.
- Door seal condition: Air leaks add run time and frost buildup.
- Room temperature and ventilation: Hot garages and tight enclosures shorten life.
- Usage habits: Frequent door openings and overpacking reduce airflow.
- Repair history: Repeated cooling issues often point to larger system wear.
- Vacuum dust from the condenser area and surrounding vents.
- Keep food from blocking interior air vents in the freezer and fresh food section.
- Confirm doors close fully and do not “bounce” back open.
- Clean and dry door gaskets; condition them lightly with appliance silicone lubricant WP542638 if they feel dry or tacky.
- Watch for early symptoms (warm temps, heavy frost, unusual fan noise).
| Symptom | Often fixable? | Common next step |
|---|---|---|
| Warm fridge but freezer cold | Yes | Check evaporator fan operation; inspect refrigerator evaporator fan motor WP2315539 |
| Heavy frost on freezer back wall | Yes | Check door seal and defrost system basics |
| Loud rattling from freezer | Yes | Inspect refrigerator evaporator fan blade WP2163777 for damage or ice contact |
| Not cooling at all | Sometimes | Professional diagnosis of sealed system and controls |
Knowing the typical lifespan helps you decide whether to repair or replace. If your WRT108FFDB03 is under about 10 years old, repairs like a fan motor, thermistor, or door gasket are often practical; past the mid-teens, major cooling-system repairs can be harder to justify.
