Understanding the Problem
This guide covers the most common problems owners report with the Whirlpool WRS315SDHZ05 side-by-side refrigerator and gives practical diagnostics and repair steps you can perform. 1) Identify the symptom - No cooling in fridge or freezer - Freezer frosting over / excessive ice on evaporator - Loud noise or rattling - Water dispenser not working or slow / ice maker not making ice 2) Quick preliminary checks (do these first) 1. Verify the refrigerator has power and is set to the correct temperature (fridge ~37°F / freezer ~0°F). 2. Listen with the doors open: does the compressor run? Do fans run? Is there airflow from freezer to fridge? (Evaporator fan runs with doors closed but often audible with door open.) 3. Check and clean the condenser coils (behind or under the unit) — dirty coils reduce cooling. 4. Inspect door seals for gaps or tears and ensure doors close fully. 3) Symptom-based diagnostics and repair steps A. Refrigerator/Freezer not cooling (compressor runs, little/no cold airflow): 1) Check evaporator fan: Open the freezer door and press the door switch — the evaporator fan should run when compressor runs. If the compressor runs and the evaporator fan does not, replace the evaporator fan motor. 2) Check for evaporator frost pattern: Remove inside freezer panels (after unplugging) and inspect evaporator coil. Heavy, uneven frost suggests defrost system failure (defrost heater, defrost thermostat/thermistor, or control board). 3) Test defrost components: use a multimeter to check continuity on the defrost heater and defrost thermostat/thermistor. If defective, replace the failed component and the defrost thermostat/thermistor as needed. 4) If evaporator is clear and fans run but no cooling, suspect sealed system (compressor or refrigerant leak) — call a certified refrigeration tech. B. Excessive frost/ice on evaporator (freezer frost build-up and reduced airflow): 1) Confirm defrost system fault: check defrost heater continuity and timer/control. If heater is open or control doesn't enter defrost, replace heater or control/board. 2) Verify defrost thermostat/thermistor (typically mounted on evaporator). Replace if open or out of spec. 3) After repairs, manually defrost (turn off and leave doors open or use hair dryer carefully) and confirm normal operation. C. No water from dispenser or slow flow / leaking 1) Confirm water supply: ensure house shutoff to fridge is open and tubing not kinked. 2) Replace the water filter if overdue — a clogged filter will reduce or stop flow. Replace with the correct EveryDrop/Whirlpool filter for this model. 3) If still no water, test the water inlet valve solenoids for continuity and correct line voltage during dispense. Replace water inlet valve if solenoids are open or valve fails to open. D. Ice maker not producing ice or making small/soft cubes 1) Ensure freezer temperature is cold enough (~0°F). Warm freezer prevents ice production. 2) Check ice maker module for power and cycle — if nothing, the ice maker assembly or its control module may need replacement. 3) Check water inlet valve and water line to ice maker; replace valve if it doesn't open. E. Loud noise (squeal, grind, rattle) 1) Identify source: compressor area (condenser fan) vs freezer interior (evaporator fan). 2) If noise comes from bottom back, inspect/replace condenser fan motor or replace fan blade if damaged. 3) If noise from freezer, access evaporator fan motor and replace if bearings are bad. 4) Example repair steps: Replace evaporator fan motor 1. Unplug refrigerator. Remove items from freezer and take out shelving/ice bin per manual. 2. Remove interior freezer rear panel (usually a few screws) to access evaporator fan assembly. 3. Disconnect fan wiring harness and remove mounting screws. Replace motor assembly with matching part. 4. Reassemble panels, power on, and test operation. 5) Example repair steps: Replace water inlet valve 1. Shut off water supply and unplug refrigerator. 2. Pull fridge away from wall, remove back access panel at bottom. 3. Note tubing positions, depress hose clamps and remove water lines from valve. Disconnect electrical connector. 4. Remove mounting screws and replace valve with OEM replacement. Reattach tubing and connectors, restore water, and check for leaks. Safety note: Always unplug the refrigerator before doing any electrical work, shut off the water supply before working on water lines, and take care when handling sharp sheet metal inside panels. If you find sealed-system problems (compressor/leak), call a licensed HVAC/refrigeration technician — those repairs require certification and special equipment.
Common Symptoms
Fridge or freezer not cooling; frost buildup on evaporator; noisy operation (fan or compressor area); water dispenser slow or not working; ice maker not producing ice.
Common Causes
- Evaporator fan motor failure (no air circulation between freezer and fridge)
- Defrost system failure (broken heater or thermostat) causing excessive frost
- Clogged condenser coils or condenser fan failure reducing heat rejection

Helpful Repair Tip
If the compressor runs but the fridge feels warm and you hear only a faint or no fan noise when the freezer door is open, the evaporator fan motor is the most likely culprit — confirm by activating the door switch (or stepping on the door switch lever) and listening for fan motor spin.
Frequently Asked Questions
How can I tell if the evaporator fan or condenser fan is bad?
Open the freezer door and press the door switch—if the compressor runs but you feel no cold air moving or hear no fan, the evaporator fan is likely bad. For condenser fan, unplug the fridge and access the rear bottom panel; spin the fan blade by hand—if it’s stiff or squeaks, replace the condenser fan motor or blade. A multimeter can check motor continuity, but a noisy or non-spinning fan is usually replaced rather than repaired.
Can I replace parts on my WRS315SDHZ05 myself, or do I need a technician?
Many user-serviceable parts (water filter, evaporator or condenser fan motors, water inlet valve, ice maker, door gaskets) can be replaced by a confident DIYer using basic tools following safety steps (unplug unit, shut off water). However, sealed-system repairs (compressor, refrigerant leaks) require an EPA-certified refrigeration technician and special tools. If you’re unsure about diagnosing electrical components or handling refrigerant, call a qualified appliance repair professional.
