Understanding the Problem
The Whirlpool WRF535SMBM00 is a French-door refrigerator commonly seen with three recurring issues: loss of cooling (warm fridge or freezer), water or ice dispenser failures, and internal leaks or frost buildup. Below are focused diagnostic steps and practical fixes for each problem. Follow the numbered steps, perform the checks in order, and replace only the failed parts. 1) Problem: Refrigerator Not Cooling (fridge warm, freezer cold or both warm) - Step 1: Check basic settings and airflow. Verify temperature settings (fridge 37°F, freezer 0°F), remove any items blocking vents between freezer and fridge, and ensure doors seal properly. - Step 2: Listen for normal operation. Confirm compressor runs (low hum) and that you hear fans (condenser fan near compressor, evaporator fan inside freezer). If compressor is off and no fans run, check power and control board. - Step 3: Inspect evaporator for frosting. Pull freezer evaporator cover (after unplugging appliance) and look for heavy frost/ice on evaporator coil — a sign of a defrost failure (defrost heater, defrost thermostat/thermistor, or defrost control). - Step 4: Test evaporator fan motor. With power on and freezer door open, the evaporator fan should run when the compressor runs. If not, test for 120VAC at the fan or continuity on the fan motor. Replace fan motor if dead. - Step 5: Test defrost components. With door open and power removed, test defrost heater for continuity and test the defrost thermostat (bi-metal) for continuity when cold. If either fails, replace; if both good, the control/board or defrost timer may be at fault. - Step 6: Check condenser fan and compressor start device. A noisy or non-spinning condenser fan or a bad start relay (overload) can cause overheating and poor cooling. Replace start device/relay if compressor tries to start but clicks or hums and won’t run. - Step 7: If compressor does not run and start device/relay is good, the compressor or sealed system (low refrigerant/leak) may be at fault — this requires an HVAC tech for sealed-system repair. Practical fix examples: replace evaporator fan motor if dead; replace defrost heater or defrost thermostat if coil is iced; replace start relay if compressor won't run but hums. 2) Problem: Ice Maker or Water Dispenser Not Working - Step 1: Verify water supply. Make sure water line to refrigerator is on and not kinked. - Step 2: Check water inlet valve. With water turned on and dispenser activated, you should hear/feel the valve open. If no water flow, test the inlet valve solenoids for continuity; replace the valve if solenoids are open or the valve is clogged. - Step 3: Check dispenser switch and actuator. If the valve opens but no water dispenses, test the dispenser switch with a multimeter when actuated. Replace switch if faulty. - Step 4: Inspect ice maker assembly. If ice maker cycles but does not fill, test the fill tube and inlet valve. If ice maker is not cycling, check the ice maker module for power and the crank arm (if tripped). Replace the ice maker module/assembly if defective. - Step 5: Check water filter. A clogged filter will reduce or stop flow. Replace filter if overdue (replace every 6 months or per use). Practical fix examples: replace water inlet valve for no fill; replace dispenser switch for unresponsive dispenser; replace ice maker assembly if it won’t cycle or eject ice. 3) Problem: Water Leaks or Pooling Inside / Under Fridge - Step 1: Identify leak source. Check inside the fridge and freezer for frost or melted ice, and inspect the drain trough and drain tube in the freezer evaporator area. - Step 2: Clear the defrost drain. Common cause is a clogged defrost drain (food debris, ice), which causes water to run into the cabinet instead of the drain pan. Remove the freezer evaporator cover, locate the drain hole, and clear with warm water or a plastic drain snake. - Step 3: Inspect water inlet line and connections. Tighten or replace any cracked water line or damaged push-fit connections that supply the dispenser/ice maker. - Step 4: Check drain pan under unit. Ensure the drain pan is seated and not cracked; also confirm the refrigerator is level front-to-back so water flows to the drain and pan. Practical fix examples: flush clogged drain with warm water and a turkey baster; replace cracked water line or faulty drain pan. Safety note: Always unplug the refrigerator or shut off power at the breaker before removing panels, testing components with exposed wiring, or working near the compressor or sealed system. When in doubt with sealed-system components (compressor, refrigerant), call a licensed HVAC/refrigeration technician.
Common Symptoms
Fridge section warm while freezer is cold; freezer iced over; no water or ice from dispenser; puddle under fridge; loud humming or clicking from compressor area.
Common Causes
- Failed evaporator fan motor or condenser fan
- Defrost system failure (heater, thermostat, or control) causing frost buildup
- Faulty water inlet valve or clogged water filter
- Clogged defrost drain or damaged drain pan
- Failed start relay or compressor/sealed-system issue

Helpful Repair Tip
Use a multimeter to check continuity on fans, defrost heater, defrost thermostat, and inlet valve solenoids. If the evaporator coil is heavily iced, start with the defrost heater and thermostat — they fail frequently and cause poor cooling.
Frequently Asked Questions
How can I tell if the compressor or the start relay is bad?
Listen and observe: if the compressor hums or clicks but won't start and you hear a repeated clicking, the start relay/overload is often bad — test the relay for continuity or replace it as a low-cost first step. If the compressor is unusually hot, runs but the system won’t hold pressure/cool, or the compressor is silent with no attempt to start and the relay is good, the compressor or sealed refrigeration system may be faulty and will require a licensed refrigeration technician and possibly a sealed-system repair.
Is it worth repairing a WRF535SMBM00 or should I replace the fridge?
Consider repair if the fridge is under 8–10 years old and the repair is limited to replaceable parts (fan motors, defrost heater, inlet valve, ice maker, control board). If the repair involves the sealed refrigerant system or a failing compressor, costs can be high — compare repair estimates to replacement cost and factor in the fridge’s age, energy efficiency, and condition. For sealed-system or compressor failures, replacement is often more cost-effective on older units.
