Whirlpool WRB329DMBW05 bottom-mount refrigerator Parts

For your Whirlpool WRB329DMBW05 bottom-mount refrigerator, the exact cubic-foot capacity depends on the specific configuration and is typically listed on the model’s rating label or in product specs. If you do not have the spec sheet, you can estimate capacity by measuring the usable interior space and converting cubic inches to cubic feet.

How to estimate cubic feet (quick method)

Use this formula to get a close estimate of your refrigerator’s capacity:

• Empty the compartment you’re measuring (fresh food and freezer can be measured separately).
• Measure interior width, height, and depth in inches (usable space, not the door bins).
• Multiply: width × height × depth = cubic inches.
• Divide by 1,728 to convert to cubic feet.
• Repeat for the freezer, then add the two results.

Conversion table

What you have	Convert to cubic feet
Cubic inches	divide by 1,728
Example: 34,560 in³	34,560 ÷ 1,728 = 20.0 ft³

What capacity range is typical for this style?

Most Whirlpool bottom-mount refrigerators commonly fall in this range:

• About 18 to 22 cubic feet for many standard-width bottom-freezer models
• Larger capacities are possible, but they are less common in compact bottom-mount designs

Why your estimate might not match “advertised” capacity

Even with careful measuring, your number can differ from published specs because:

• Shelves, drawers, and air channels reduce usable space
• Door bins are often excluded from “interior box” measurements
• Some published capacities include areas you cannot easily measure accurately

Related parts that affect usable space (bins, drawers, sealing)

If you are trying to restore storage space or improve temperature performance, these model-matched parts can help:

• Replace a cracked bin with the refrigerator door bin WPW10371194
• Improve sealing if warm air is leaking past the door with the refrigerator door gasket (white) WPW10443309
• If the freezer drawer is not tracking smoothly, check the refrigerator freezer drawer gear 12002497

Whirlpool refrigerator model numbers (including WRB329DMBW05) identify the product type, size/series, and the exact engineering revision. We use the full model number to match the correct parts list and diagrams so you order components that fit your specific bottom-mount refrigerator.

What each part of a Whirlpool model number usually tells you

Most Whirlpool refrigerator model numbers follow a pattern like this:

• Prefix letters: brand/product platform (for example, many Whirlpool refrigerators start with W)
• Middle digits/letters: series, capacity class, and feature set (varies by product line)
• Trailing numbers/letters: the engineering revision (this is critical for parts compatibility)

Example breakdown (typical)

Section	What it commonly indicates	Why you care
Leading letters	Product line/platform	Helps narrow the correct parts family
Core number string	Series and configuration	Helps match shelves, bins, and door parts
Ending revision code	Version changes over time	Prevents ordering a part that looks right but will not mount or plug in

Where to find the model number on the refrigerator

On Whirlpool bottom-mount refrigerators, the model/serial tag is commonly found:

• Inside the fresh food compartment on a side wall
• Near the crisper drawer area
• Along the door frame (fresh food section)
• Occasionally behind the toe grille area

Write the model number exactly as shown, including all letters and digits.

Why it matters for WRB329DMBW05 parts

Even small revision changes can affect fit and wiring. For example, when diagnosing a light or door alarm issue, we match the correct door switch for your exact model, such as the refrigerator door switch W11396033.

Quick tips before ordering parts

• Use the full model number: WRB329DMBW05 (do not drop the last two digits)
• Compare symptoms to common failure items (switches, thermistors, fan motor)
• If you are shopping beyond the parts shown for this model, search by model number on Sears PartsDirect

The most common Whirlpool refrigerator problem is a cooling complaint (fresh food warm, freezer not cold enough, or temps swinging). On a Whirlpool WRB329DMBW05 bottom-mount refrigerator, the most frequent root causes are airflow restrictions (dirty condenser coils, blocked vents) or a defrost and fan issue that prevents cold air from circulating.

Most common symptoms and what they usually point to

• Refrigerator section warm, freezer OK: restricted airflow, evaporator fan issue, or frost buildup on the evaporator
• Freezer warm and refrigerator warm: dirty condenser coils, condenser airflow problem, or sealed system/compressor issue
• Loud humming or rattling: fan blade hitting ice or a failing fan motor
• Water under the fridge or in the freezer: clogged/iced defrost drain
• Lights work but cooling is weak: door not sealing, fan not running, or temperature sensing problem

Quick checks we recommend first (no parts needed)

1. Clean the condenser coils (dust buildup is a top cause of poor cooling and long run times).
2. Confirm vents are not blocked by food packages in the refrigerator or freezer.
3. Check door closure and gasket contact all the way around.
4. Listen for the evaporator fan when the compressor is running (you should typically hear airflow).
5. Look for frost buildup on the freezer back wall (often points to a defrost problem).

Common parts that fix “not cooling” complaints on WRB329DMBW05

If the basic checks do not restore normal temperatures, these model-matched parts are frequent fixes:

Problem you notice	Likely part area	Model-matched part to consider
No airflow from freezer, fan noisy, or fan not spinning	Evaporator fan	Refrigerator evaporator fan motor WPW10128551 or refrigerator evaporator fan blade WP2169142
Temps swing or unit runs too long	Temperature sensing	Refrigerator thermistor 12002355
Lights do not respond correctly to door opening, fan stops when door shuts	Door switch circuit	Refrigerator door switch W11396033
Water pooling, ice under freezer basket	Defrost drain path	Extension-dr W10619951

Why it matters

Cooling problems usually start small (longer run times, soft ice cream, warm milk) and then turn into food-spoilage issues. Addressing airflow, door sealing, and fan operation early helps your WRB329DMBW05 maintain stable temperatures and reduces strain on the compressor.

Most Whirlpool refrigerators last 10 to 18 years with normal household use; for a Whirlpool bottom-mount refrigerator like WRB329DMBW05, consistent cleaning and good door sealing are the biggest factors that keep it running closer to the high end of that range.

What affects refrigerator lifespan the most

• Condenser coil cleanliness (dust buildup makes the compressor work harder)
• Door gasket condition (air leaks cause longer run times and frost issues)
• Door alignment and closing habits (doors left ajar strain the cooling system)
• Room temperature and ventilation space around the cabinet
• Ice maker and water system upkeep (if equipped)

Quick maintenance checklist (best return for the effort)

• Vacuum dust from the front grille and coil area every 6 to 12 months.
• Keep the freezer packed but not blocked; don’t cover air vents.
• Confirm the doors close on their own and don’t bounce open.
• Clean and dry spills quickly to prevent odors and drain clogs.
• If temperatures swing, troubleshoot the sensor and airflow before food spoils.

Common “wear items” that can shorten life (and what they do)

Part type	What you may notice	Example part for WRB329DMBW05
Door switch	Light stays off/on incorrectly, fan behavior changes when door opens	Refrigerator door switch W11396033
Evaporator fan motor	Warm fridge, weak airflow, unusual fan noise	Refrigerator evaporator fan motor WPW10128551
Thermistor (temperature sensor)	Temps too warm or too cold, inconsistent cycling	Refrigerator thermistor 12002355

Why it matters

A refrigerator that runs longer and harder than it should (from dirty coils, air leaks, or poor airflow) puts extra stress on the sealed system and compressor. Keeping run time under control is the simplest way to extend service life.
