Whirlpool WRS331FDDB02 side-by-side refrigerator Parts

For the Whirlpool WRS331FDDB02 side-by-side refrigerator, the most common problems we see are temperature control issues (warm fridge or freezer, running too long) and ice maker or water dispenser troubles. These are often tied to airflow problems, dirty condenser coils, or a water supply component starting to fail.

Most common symptoms and what they usually point to

• Fridge section warm but freezer cold: restricted airflow or evaporator fan issue
• Both sections warm: condenser airflow problem, sealed system issue, or control problem
• Ice maker not making ice: water supply restriction, inlet valve issue, or ice maker failure
• Water dispenser slow or not dispensing: filter restriction, air in the line, or inlet valve issue
• Clicking, buzzing, or intermittent cooling: compressor start components, inverter, or control board concerns

Quick checks we recommend first (no parts needed)

• Set temperatures to typical targets: 37°F fresh food and 0°F freezer
• Make sure vents inside both compartments are not blocked by food packages
• Clean dust from the condenser area (restricted airflow can cause long run times)
• Confirm the household water shutoff valve is fully open
• After any water filter change, purge air by dispensing several cups of water (this helps ice maker fill issues too); see how to purge air from a refrigerator water dispenser video

Parts that commonly solve these issues on WRS331FDDB02

Problem area	What fails most often	Example part for this model
Ice production	Ice maker module or assembly	Refrigerator ice maker assembly WPW10300022
Water to ice maker/dispenser	Inlet valve not opening fully or sticking	Refrigerator water inlet valve WPW10179146
Lights and some control functions	LED/light control board	Refrigerator light board WPW10515057

Why it matters

When cooling airflow or water supply is even slightly restricted, a side-by-side refrigerator like the Whirlpool WRS331FDDB02 can run longer, struggle to hold temperature, and produce small or hollow ice cubes. Catching the early signs helps prevent food spoilage and reduces wear on the compressor.

If your Whirlpool WRS331FDDB02 side-by-side refrigerator dispenses water but won’t make ice, the most common causes are a freezer temperature that’s too warm, a blocked/frozen fill tube, or a weak/failed dual water inlet valve that can still supply the dispenser but not the ice maker.

Quick checks we recommend first

• Confirm the freezer is at 0°F to 5°F; ice production drops fast above this range.
• Make sure the ice maker is turned ON and the shutoff arm (or switch) is in the ON position.
• Dump old cubes and check the ice bin for clumps; a jam can stop harvesting.
• Look for a frozen fill tube at the back of the ice maker (ice maker mold stays dry).
• Verify the household water supply valve is fully open and the line is not kinked.

Water works but ice doesn’t: what that usually means

In many Whirlpool side-by-side designs, the dispenser and ice maker use separate outlets on the same valve. The dispenser side can work normally even if the ice maker side is restricted or failing.

Symptom	Most likely cause	What to do next
Dispenser works, ice maker mold stays dry	Ice-side valve not opening or fill tube frozen	Inspect fill tube; test/replace valve if needed
Ice maker cycles but no water fill	Valve issue or wiring to ice maker	Check valve, harness connections
Small/hollow cubes	Low water pressure or partial restriction	Replace filter if used; check supply pressure

Parts that commonly fix this on WRS331FDDB02

• Dual water inlet valve: If the ice side is weak, replacing the valve often restores ice production. Use the model-matched refrigerator water inlet valve WPW10179146.
• Ice maker assembly: If the valve is good and the ice maker won’t cycle/harvest, the complete assembly is a common repair. Use refrigerator ice maker assembly WPW10300022.

Why it matters

An ice maker needs colder temperatures and a reliable timed water fill. When either is off, you can still get drinking water at the door while the ice maker quietly stops producing.

A Whirlpool refrigerator typically lasts 10 to 20 years. For a Whirlpool WRS331FDDB02 side-by-side refrigerator, lifespan depends most on condenser airflow, door seal condition, and how hard the ice maker and water system work day to day.

Typical lifespan range (what to expect)

Most Whirlpool refrigerators fall into these real-world ranges:

• 10 to 15 years: common for units with heavy daily use
• 15 to 20 years: achievable with consistent maintenance and stable temperatures
• Shorter lifespan: more likely when the ice maker, dispenser, or airflow is restricted

Usage and care level	Typical outcome	What usually fails first
Basic care, average use	10 to 15 years	Ice maker, water valve, fan, controls
Good care, clean airflow	15 to 20 years	Wear items, seals, dispenser parts
Poor airflow, dirty coils	Under 10 to 12 years	Compressor system runs hot, cooling issues

What extends the life of a side-by-side refrigerator

These steps reduce compressor run time and prevent common failures:

• Keep the condenser area clean and make sure air can flow behind and under the cabinet
• Keep doors closed as much as possible; avoid long “standing open” door time
• Set temps correctly (about 37°F fresh food and 0°F freezer)
• Replace worn door gaskets so warm air does not leak in
• Fix slow water dispensing early so the ice maker does not starve for water
• Level the refrigerator so doors self-close and seals seat evenly

Parts that commonly affect longevity on this model

If performance drops, these are common repair points on the WRS331FDDB02:

• Refrigerator water inlet valve WPW10179146 (ice maker not filling, weak dispensing)
• Refrigerator ice maker assembly WPW10300022 (no ice, small cubes, intermittent harvest)
• Refrigerator electronic control board WPW10366605 (erratic temps, fan or defrost control issues)
• Compressor W11305045 (warm fridge/freezer, long run times, poor cooling)

Why it matters

A refrigerator that runs longer than it should (from dirty coils, air leaks, or restricted airflow) wears out the sealed system faster. Simple maintenance often adds years of reliable cooling and helps avoid expensive compressor-related repairs.
