Understanding the Problem
The Whirlpool WRS588FIHV0 is a side-by-side refrigerator with through-the-door dispenser and automatic ice maker. The most common service calls for this model are: no cooling or weak cooling, ice maker or dispenser failures, frost build-up in the freezer, unusual noises, and water leaks. Below are practical, prioritized diagnostic and repair steps you can follow at home. 1) Start with quick checks (5–10 minutes) 1.1. Confirm the fridge has power: ensure the unit is plugged in and the outlet is live. Check that the display or interior light turns on. 1.2. Verify temperature settings: refrigerator 37°F (3°C) and freezer 0°F (-18°C) are typical targets. If settings were recently changed, allow 24 hours to stabilize. 1.3. Inspect for obvious obstructions: make sure vents inside freezer and fridge aren’t blocked by food packages. 2) If the refrigerator is not cooling (warm fridge or freezer) 2.1. Check condenser coils: unplug the fridge, pull it forward and inspect/clean dust and lint from the coils and coil fan. Dirty coils reduce cooling significantly. 2.2. Confirm condenser fan and evaporator fan operation: with power on, open freezer and listen for the evaporator fan. Remove the kick grill to check the condenser fan near the compressor. If a fan doesn’t run, plan to replace that fan motor. 2.3. Check frost pattern on evaporator: remove the freezer back panel (power off first). Even light frost is normal; heavy, uneven frost or a solid block of ice indicates a defrost failure (defrost heater or defrost thermostat/thermistor or control board problem). 2.4. Listen to compressor and start relay: compressor should hum and feel warm. A repeated clicking or very hot relay often means a failed start device or compressor issue. Swap the relay only if you’re comfortable; a failed compressor usually requires a sealed-system tech. 2.5. Test thermistors/temperature sensors: if fans run and compressor runs but temperatures are off, thermistors (often 10k NTC style) may be reading incorrectly. Use a multimeter to check resistance vs. temperature, or temporarily compare readings to expected values in the tech sheet. 2.6. If evaporator has heavy frost and defrost system fails, replace defrost heater, defrost thermostat, and/or check the main control/defrost timer or board. How to fix: clean coils, replace failed fans, replace defrost heater/thermostat or defrost control board as diagnosed, replace start relay if defective. For sealed-system (compressor, refrigerant) issues call a certified technician. 3) Ice maker not making ice / slowly making ice 3.1. Confirm water supply: ensure the water line is on and water filter not clogged. Replace filter if >6 months old or test by bypassing the filter. 3.2. Check water dispenser and fill: run the water dispenser — if it’s weak or absent, suspect the water inlet valve or clogged filter/line. 3.3. Inspect ice maker assembly: look for a stuck arm, ice jam, or frozen fill tube. Manually advance the ice maker test cycle (consult tech sheet) to see if it fills and harvests. 3.4. Test the water inlet valve: during a fill cycle, listen for valve activation and check for flow. No fill with valve energised = bad valve or blocked line. How to fix: replace water filter, thaw or repair fill tube, replace ice maker module or water inlet valve as confirmed. 4) Dispenser problems (no water or ice at the door) 4.1. Check the water filter first — a clogged filter is the most common cause of weak/no water. 4.2. Verify the dispenser switch and actuator: remove the dispenser trim to access the switches; depress the switch and test for continuity. 4.3. Inspect the dispenser control board and wiring harness for damage or loose connectors. How to fix: replace filter, dispenser switch, inlet valve, or dispenser control board depending on diagnostic results. 5) Leaks or pooled water 5.1. Check the drain tube and defrost drain: remove rear panel in fresh-food section and inspect for ice clog in the drain trough — thaw with warm (not boiling) water and clear the tube. 5.2. Inspect water inlet line and connection behind fridge. How to fix: clear defrost drain, re-seat or replace water line, replace leaking valve. 6) Unusual noises 6.1. Identify source: evaporator fan, condenser fan, or compressor. Fans are common culprits and relatively easy to replace. 6.2. Rattles may be from items touching the condenser/coils or the compressor mounting pads. How to fix: tighten/secure panels, replace noisy fan motors, replace pads or dampers as needed. Safety note: Always unplug the refrigerator before accessing internal components that require panel removal. When testing electrical components use insulated tools and follow basic electrical safety. For sealed-system repairs (compressor/refrigerant) or tasks requiring refrigerant recovery, call a licensed HVAC/refrigeration technician — those repairs require EPA certification and special equipment.
Common Symptoms
Not cooling or weak cooling, ice maker not producing or slow production, weak/no water from dispenser, frost building in freezer, unusual noises, water leaks under fridge.
Common Causes
- Dirty condenser coils or blocked airflow
- Failed evaporator or condenser fan motor
- Defrost system failure (heater, thermostat, or control board)
- Clogged water filter or faulty water inlet valve
- Faulty temperature sensors/thermistors or main control board
- Sealed system failure (compressor or refrigerant leak)

Helpful Repair Tip
To confirm an evaporator fan failure: open the freezer door and listen. If the compressor runs but there is no airflow in the freezer and refrigerator, power off, remove the freezer back panel and try spinning the fan blade by hand — it should spin freely; if not running when power is on, replace the evaporator fan motor.
Frequently Asked Questions
How long should I wait after cleaning coils or changing a filter to see improvement?
After cleaning condenser coils or replacing a clogged water filter, you may notice water flow improvement immediately, but temperature improvements can take 12–24 hours to stabilize. Give the refrigerator at least 24 hours to recover after a major change before concluding the repair was or wasn't successful.
My freezer is cold but the fresh food section is warm — what should I check first?
First check that the evaporator fan in the freezer is running and that vents between freezer and fresh food section are not blocked. If the evaporator fan works and vents are clear, check the air damper (evaporator air control) and the thermistor/temperature sensors; also verify the defrost system isn't creating ice blockage on the evaporator that restricts airflow.
