Whirlpool WRS331FDDW00 refrigerator Parts

For your Whirlpool WRS331FDDW00 side-by-side refrigerator, the most accurate way to find cubic feet (capacity) is to look it up by model number in the specifications section of the WRS331FDDW00 owner's manual. If you need a quick estimate, you can calculate interior volume by measuring and converting cubic inches to cubic feet.

Fast ways to get the capacity

• Check the WRS331FDDW00 owner's manual for the listed capacity/specifications.
• Look for a model and serial tag inside the fresh food compartment (often on a side wall or ceiling area) and confirm the model is WRS331FDDW00.
• Use the measurement method below when you only need an estimate (for moving, storage planning, or comparing sizes).

How to estimate cubic feet by measuring

1. Empty the compartment you are measuring (refrigerator side and freezer side).
2. Measure the usable interior:
   • Width (inches)
   • Height (inches)
   • Depth (inches)
3. Multiply: width x height x depth = cubic inches.
4. Convert to cubic feet: cubic inches ÷ 1,728 = cubic feet.

Quick conversion table

What you have	What to do	Result
Interior measurements in inches	Multiply W x H x D	Cubic inches
Cubic inches	Divide by 1,728	Cubic feet (cu. ft.)

Why your estimate may not match the published number

Manufacturers rate capacity using standardized methods; your tape-measure estimate can differ because shelves, bins, air ducts, and the evaporator cover reduce usable space.

• Published capacity: best for comparing models.
• Measured usable space: best for knowing what will actually fit.

Related tip for planning space

If you are checking fit in a kitchen opening, use the clearances listed in the installation guide (side, top, and rear spacing) because capacity does not tell you the outside dimensions.

The most common Whirlpool refrigerator problem is cooling performance (food not staying cold enough or freezer warming up). On the Whirlpool WRS331FDDW00, the most frequent root causes are airflow and temperature-control issues, plus ice maker and water system problems that show up as no ice, small cubes, or leaks; our WRS331FDDW00 installation guide troubleshooting section covers these symptoms and first checks.

Most common symptoms we see (and what they usually point to)

• Refrigerator or freezer too warm: door not sealing, heavy door openings, warm room, blocked vents, or a fan/compressor control issue
• Ice maker not making ice or making small/hollow cubes: water supply shutoff not fully open, kinked water line, ice maker switched off
• Water leaking or puddles: kinked/loose water line, drain pan/defrost water issues, or a valve that is not closing fully
• Noisy operation: normal compressor and fan sounds, items rattling on top, or water moving through the line
• Runs “all the time”: energy-efficient compressor and fans running longer at lower speeds (often normal)

Quick checks first (fast, no parts)

• Confirm the unit is plugged into a grounded 3-prong outlet (no extension cord).
• After a new install or power loss, allow 24 hours for full cooling.
• Make sure doors close fully; re-seat bins and shelves so nothing holds the door open.
• If ice is the issue, verify the water shutoff valve is fully open and the supply line is not kinked.
• If the refrigerator is not connected to water, turn the ice maker off to prevent valve cycling noises.

Common causes and likely fixes (WRS331FDDW00)

Problem you notice	Most likely cause	What we typically do next
Too warm	Airflow/controls/door sealing	Check vent blockage, door closure, then test fans and controls
No ice or small cubes	Low water flow	Straighten line, open shutoff, then test valve
Water at dispenser/ice issues	Water supply component problem	Diagnose valve and tubing

If you suspect low water flow or intermittent filling, the water inlet valve is a common failure point; for this model, see the refrigerator water inlet valve WPW10179146.

Why it matters

Cooling and water-flow problems can cascade: poor airflow raises temperatures, which reduces ice production; low water flow makes hollow cubes and can also cause dispenser complaints. Catching the simple causes first prevents unnecessary part replacement.

A Whirlpool refrigerator typically lasts 10 to 18 years. For your Whirlpool WRS331FDDW00 side-by-side, consistent care (good airflow, clean condenser area, correct temperatures, and a solid door seal) is what most directly determines whether it lands on the low or high end of that range.

What affects lifespan the most

• Room temperature and ventilation: Install in a space that stays within the recommended ambient range; extreme heat makes the compressor run longer.
• Door openings and loading: Frequent openings and warm food loads increase run time.
• Cleaning and upkeep: Keeping the unit clean helps it cool efficiently.
• Water and ice system condition: A healthy water supply and valve operation reduces strain and leaks.
• Door seal condition: A leaking gasket forces longer run times and can cause temperature swings.

Quick maintenance checklist (high impact)

• Vacuum dust from the condenser area regularly (more often with pets).
• Keep vents inside both compartments clear of food packages.
• Set temperatures, then wait 24 hours after changes for full stabilization.
• Confirm doors close fully and the gasket seals all the way around.
• If you have water/ice connected, watch for slow fill, leaks, or buzzing from the valve.

What “normal” operation looks like on newer Whirlpool fridges

Your WRS331FDDW00 uses an energy-efficient cooling system, so longer run times can be normal, especially in warm rooms or with frequent door openings.

Symptom	Often normal	Often needs attention
Compressor runs a lot	Warm room, heavy use, recent install	Poor airflow, dirty condenser, bad door seal
Buzzing/clicking	Water valve opening/closing	Buzzing with no water use, leaking valve
Popping/whirring	Normal temperature regulation	Loud grinding or constant rattling

Why it matters

A refrigerator that runs efficiently maintains steadier temperatures, reduces wear on the compressor and fans, and helps you get the full expected service life before major parts (like the compressor or control board) become a concern.

For model-specific care and operating guidance, follow the Whirlpool WRS331FDDW00 Owner's manual.
