Understanding the Problem
This guide covers the common service issues on the Whirlpool model WRF736SDAM14: not cooling, freezer frost/ice buildup, noisy fans, ice maker or water problems, and door seal issues. Follow these numbered diagnostic and repair steps to isolate and fix the fault. 1) Safety and preliminaries: Unplug the refrigerator or switch off its breaker before any internal inspection. Remove food from affected compartments or relocate to a cooler if repair will take time. Have a multimeter, nut drivers, Torx bits, and cavity-safe gloves ready. 2) Verify symptoms and simple checks: • Confirm true temperature issue with a separate thermometer in both fridge and freezer. • Listen for compressor run/hum (back lower area) and for evaporator or condenser fans. • Check that condenser coils are clean and clearance/venting around the fridge is adequate. 3) If fridge/freezer not cooling but compressor runs: • Clean condenser coils and retest. • Check condenser fan (motor near compressor): remove lower rear kickplate, power on (briefly) and listen. If fan not spinning, remove and test motor for continuity; replace if dead. 4) If compressor not running: • Check for power to unit and to compressor start components (start relay/overload). A loud click then silence can indicate a failed start relay or a seized compressor (rare). Replace start relay/overload. 5) If freezer cool but fresh food section warm: • Check air diffuser/damper between freezer and fridge (usually behind control housing). If damper is stuck or motorized damper not opening, replace or repair damper assembly. 6) If evaporator frost/ice buildup (warm fridge, frost covering evaporator coil): • Remove freezer back panel to visually inspect evaporator. Heavy ice indicates defrost system failure (defrost heater, defrost thermostat/bi-metal, or main control/defrost timer). Test defrost heater and thermostat for continuity with a multimeter; if either open, replace. Also check defrost heater harness connections. 7) If fans noisy or not running: • Evaporator fan (inside freezer) can seize with ice or fail electrically. Defrost the coil and test fan motor for continuity; replace fan blade/motor assembly if noisy or dead. 8) Water/ice maker issues: • If no water to dispenser or slow fill: check water filter (replace if >6 months), water inlet valve (solenoid), and supply line pressure. If dispenser leaks or drips, check dispenser actuator and valve. • If ice maker won’t cycle or produces little/no ice: check the icemaker module (test for 120V or data signal depending on model), water valve, and fill tube for ice blockages; replace failing icemaker assembly. 9) Door gasket and sealing: • Check door gasket for gaps, tears, or debris. Replace gasket if it does not seal; warm spots along the seal or persistent condensation are clues. 10) Final tests: after any repair, restore power and allow 24–48 hours for temperatures to stabilize; verify with thermometer and inspect for recurring symptoms. Safety note: Always disconnect power before opening panels. Use proper protective equipment when working near sharp sheet metal, refrigerant-carrying components, and electrical connections. When compressor or sealed system work is required (compressor replacement, refrigerant repair), use a certified HVAC/refrigeration technician.
Common Symptoms
Not cooling in fridge or freezer, frost/ice on evaporator or inside freezer, loud or no fans, ice maker not filling or not making ice, water dispenser slow or not working, warm spots along door seal.
Common Causes
- Clogged condenser coils or poor airflow
- Failed evaporator fan, condenser fan, or compressor start relay
- Defrost system failure (heater, thermostat or control) causing frost buildup

Helpful Repair Tip
Start by confirming whether the compressor runs and whether fans run; if the compressor runs but temperatures are poor while frost covers the evaporator, suspect the defrost system (heater, thermostat, or control) first.
Frequently Asked Questions
My WRF736 freezer has heavy frost on the evaporator and the fridge is warm — what should I test first?
Heavy frost on the evaporator with poor cooling in the fresh-food section strongly suggests a defrost failure. Unplug the unit, remove the freezer back panel, and inspect the evaporator coil. If you see thick ice, test the defrost heater and defrost thermostat for continuity with a multimeter. Also inspect the defrost heater harness and connectors. Replace the open component(s) and clear the ice before restoring power.
The ice maker stopped making ice — do I need a full icemaker replacement?
Not always. First check: is the water filter new and the water supply valve open? Second, check the fill tube for frozen blockages and the water inlet valve for proper fill (you can listen for the valve clicking during a harvest cycle). If the icemaker doesn't cycle electrically, test the icemaker module for voltage or use the manual harvest/test button if equipped. If module electronics or the mold heater are bad, replace the icemaker assembly. If the valve is failing, replace the water inlet valve.
