Understanding the Problem
The Whirlpool WRX735SDBM04 is a French-door refrigerator commonly suffering from a few repeatable issues: not cooling or uneven cooling, ice maker or dispenser failures, water leaks, noisy operation, and door-seal problems. Below are systematic, prioritized diagnostic and repair steps you can follow at home. 1) Verify basics and reproducible symptom - Check the refrigerator is plugged in and the display/control panel is on. Confirm temperature settings: refrigerator 37°F (3°C) and freezer 0°F (-18°C) as a baseline. - Confirm symptom: whole unit warm, only fridge warm, only freezer warm, ice maker not producing, dispenser no water, leak location, or unusual noise. 2) If the unit (compressor) is not running or not cooling at all - Diagnostic steps: a) Listen for compressor and feel for vibration at the back. Check if condenser fan (at bottom/back) and evaporator fan (inside freezer) are running. b) Inspect condenser coils: remove kickplate and vacuum coils and motor area if dirty. c) Test outlet with another device and check house breaker. - How to fix: - Clean condenser coils thoroughly and re-test. Clogged coils cause overheating and poor cooling. - If compressor not running and power is good, test start relay/overload (unplug, remove relay and shake — a rattling or burnt smell indicates failure). Replace relay/overload assembly if needed. - If compressor hums but will not run, or start components ok and compressor fails, sealed system fault requires certified tech (compressor/ refrigerant service). 3) If freezer is cold but fridge is warm (or uneven cooling) - Diagnostic steps: a) Listen for evaporator fan noise when freezer door is closed. If fan stops when doors open, close doors and listen again. b) Check the air damper/vent between freezer and refrigerator for blockage or stuck position. c) Inspect for frost build-up on the evaporator (pull freezer back panel if comfortable) — excessive frost indicates a defrost failure. - How to fix: - Replace evaporator fan motor if it’s silent when compressor runs. (Often behind freezer rear panel.) - Replace or clean damper/actuator if it’s stuck or failing to open. - If evaporator is frosted up, test defrost heater, defrost thermostat (NTC), and defrost control/board — replace failed components. 4) Ice maker not making ice or making small/odd-shaped cubes - Diagnostic steps: a) Verify water supply valve to the fridge is fully open. b) Check water filter age — clogged filter reduces water flow and ice production. c) Inspect ice maker for obvious jammed cubes or frozen fill tube. d) Run a manual ice-maker harvest test from the control panel (consult manual for exact steps) and observe fill cycle. - How to fix: - Replace water filter if older than 6 months or if flow is poor (EveryDrop/Whirlpool filter). - Replace ice maker assembly if motor/harvest cycle does not run or fill valve doesn’t open. - Replace water inlet valve if it fails to open during fill. 5) Water dispenser not working or leaking - Diagnostic steps: a) Confirm filter and water supply are good and valve is open. b) Check water pressure and inspect inlet tubing for kinks or freeze. c) Examine dispenser actuator and solenoid for operation. - How to fix: - Replace clogged water filter. - Replace faulty water inlet valve if it does not open under command. - If tubing is frozen, thaw and insulate; if damaged, replace water line. 6) Noisy operation (loud clicking, buzzing, rattles) - Diagnostic steps: a) Identify where noise originates: top, back, bottom-front (compressor area), or inside (fan area). b) Run unit and isolate sound by placing a cardboard tube as a stethoscope to the back components. - How to fix: - Replace noisy evaporator or condenser fan motors. - Tighten or replace broken mounting brackets or vibration pads. - Replace relay/overload if compressor is clicking and failing to start. 7) Door seals and leaks - Diagnostic steps: a) Inspect gaskets for tears, gaps, or debris; perform dollar-bill test to check seal. b) Look for condensation or pooled water — note exact location. - How to fix: - Clean or replace door gasket if damaged; tighten hinge or adjust door if sagging. - Inspect and clear drain tube and defrost drain pan if leaking inside fridge; clear clogs with warm water and a pipe cleaner. Safety note: Always unplug the refrigerator or turn off its circuit at the breaker before removing panels or testing electrical components. When in doubt about sealed-system repairs (compressor, refrigerant), call a certified HVAC/ refrigeration technician — handling refrigerant requires special licensing and tools.
Common Symptoms
No cooling or uneven cooling between fridge and freezer, ice maker or dispenser failures, water leaks, and loud or unusual noises.
Common Causes
- Dirty condenser coils or failed condenser fan causing overheating
- Evaporator fan, damper, or defrost system failure causing poor fridge cooling
- Faulty ice maker, water inlet valve, or clogged water filter causing ice/dispenser issues

Helpful Repair Tip
If the compressor is running but the freezer fan is silent, the evaporator fan is often the culprit — remove the freezer rear panel and test the fan for 120V (or continuity) while the compressor runs.
Frequently Asked Questions
How often should I change the water filter in my WRX735SDBM04?
Replace the water filter every 6 months or sooner if you notice reduced flow or odd taste/odor. A clogged filter often causes slow dispenser flow and reduced ice production.
My refrigerator is running but the fridge is warm — can I fix this myself?
Yes, often. First check condenser coils for dust, ensure evaporator fan runs, and make sure the air damper between freezer and fridge isn’t stuck. Replace the evaporator fan or damper actuator if they fail. If the evaporator is frosted up or compressor/start components are faulty, you may need professional service.
