If your Whirlpool WRX735S Series refrigerator is giving you trouble, this guide covers the most common problems homeowners run into, including cooling issues, water leaks, ice maker failures, dispenser problems, and unusual noise. Each section explains the likely causes, the first checks to make, and the replacement parts that are commonly involved.

The Whirlpool WRX735S line includes several closely related models that share similar construction and service parts. That means many of the same troubleshooting steps apply across the series, but it is still important to confirm your exact model number before ordering replacement components.

Common Whirlpool WRX735S Refrigerator Issues and How to Fix Them

1. Whirlpool WRX735S Refrigerator Not Cooling

Symptoms:

• The refrigerator section feels warm

• The freezer is too cold or has frost buildup

• Temperature fluctuates or feels inconsistent

Possible causes:

• Faulty evaporator fan

• Broken thermostat

• Dirty condenser coils

• Malfunctioning compressor

• Blocked air vents

• Dirty or clogged air filter

How to fix it:

1. Clean the condenser coils at the back or beneath the refrigerator. Dust buildup can reduce cooling efficiency.

2. Check the evaporator fan inside the freezer. If it is not running, the motor may be bad or the blade may be frozen.

3. Lower the thermostat setting slightly and listen to see whether the compressor starts.

4. Inspect vents and filters for blockages and clear away anything that is restricting airflow.

Replacement parts you may need:

• Condenser fan motor: WPW10312695

• Evaporator fan motor: WPW10339370

• Thermostat: WPW10142208

For WRX735S0 or WRX735S1, confirm compatibility against the model-specific parts diagram.

2. Whirlpool WRX735S Refrigerator Leaking Water

Symptoms:

• Water pools at the bottom of the refrigerator

• Water leaks around the door area

• Leaking appears in or near the ice maker area

Possible causes:

• Clogged defrost drain

• Faulty door gasket

• Broken door seal

• Ice maker water supply issue

• Blocked or leaking water filter

How to fix it:

1. Inspect the defrost drain for blockages. A clogged drain can force water into the refrigerator compartment or onto the floor.

2. Check the door gasket for dirt, cracks, or sections that are not sealing properly. Clean or replace it if needed.

3. If the leak is near the ice maker, inspect the water line connections and replace any worn seals or fittings.

Replacement parts you may need:

• Defrost drain hose: WPW10275888

• Water filter: 4396508

• Door gasket: WPW10125509

• Ice maker valve: WPW10247722

For WRX735S0 or WRX735S1, verify the exact model number before ordering parts.

3. Whirlpool WRX735S Refrigerator Ice Maker Not Working

Symptoms:

• No ice production

• Ice is small or oddly shaped

• Ice maker does not fill with water

Possible causes:

• Frozen water line

• Faulty water valve

• Defective ice maker motor

• Clogged water filter

• Low water pressure

How to fix it:

1. Check the water valve behind the refrigerator. If it is blocked or malfunctioning, the ice maker may not fill properly.

2. Inspect the water line for kinks or frozen sections. Thaw or replace the line as needed.

3. Replace the water filter if it is clogged and restricting flow.

4. If the motor is running but no ice is being produced, the ice maker motor may have failed.

Replacement parts you may need:

• Water valve: WPW10312695

• Ice maker motor: WPW10309363

• Water filter: 4396508

For WRX735S0 or WRX735S1, check the parts catalog to confirm the correct version.

4. Whirlpool WRX735S Refrigerator Making Noise

Symptoms:

• Humming, buzzing, or rattling sounds

• Grinding or popping noises during operation

Possible causes:

• Loose fan blades

• Worn condenser fan

• Dirty condenser coils

• Faulty compressor motor

• Vibrating shelves, bins, or internal parts

How to fix it:

1. Check the condenser fan for debris or wear and clean or replace it if needed.

2. Inspect the compressor if the noise seems to come from the lower rear of the refrigerator. A rattling compressor may be failing.

3. Make sure shelves, bins, and racks are seated properly so they do not vibrate during operation.

Replacement parts you may need:

• Condenser fan motor: WPW10312695

• Compressor motor: W10301398

Always match the part number to your specific WRX735S model revision before purchase.

5. Whirlpool WRX735S Refrigerator Not Dispensing Water

Symptoms:

• Water dispenser does not work

• Water comes out slowly

• No water flow from the dispenser at all

Possible causes:

• Clogged water filter

• Faulty water valve

• Frozen water line

• Dispenser motor malfunction

How to fix it:

1. Replace the water filter first. A clogged filter is one of the most common reasons for weak or no water flow.

2. Check the water line for freezing or obstructions and thaw it if necessary.

3. Inspect the water valve and dispenser motor and replace either one if it is not operating correctly.

Replacement parts you may need:

• Water valve: WPW10312695

• Water filter: 4396508

Verify compatibility with WRX735S0 or WRX735S1 before ordering.
