Whirlpool WRT108FFDB03 refrigerator Parts

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.

Fast ways to find 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.

How to estimate cubic feet by measuring

1. Empty the section you are measuring (refrigerator and freezer are usually calculated separately).
2. Measure usable interior:
   • Width (inches)
   • Height (inches)
   • Depth (inches) (do not include door bins)
3. Multiply: width × height × depth = cubic inches.
4. Convert: cubic inches ÷ 1,728 = cubic feet.

Quick conversion table

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

Why your estimate may not match the published number

• 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.

Related parts that affect usable space and sealing

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.

Why it matters

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.

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.

What each section of a Whirlpool model number usually means

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.

Where to find the model number on a top-mount refrigerator

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)

Model number vs. serial number (and why both matter)

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

Why it matters for parts lookup

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.

Quick tips to avoid common mistakes

• 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)

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.

Quick checks we recommend first

• 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.

Common symptoms and the most likely cause

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

Parts that commonly fix cooling and airflow problems

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

Why it matters

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.

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.

Typical lifespan and what affects it

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.

Quick maintenance checklist (keeps you closer to 18 years)

• 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).

Common “end-of-life” symptoms vs. fixable issues

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

Why it matters

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.
