Understanding the Problem
This guide covers the most common problems owners see on the Samsung NX58H9500WS/AA (not cooling, frost buildup, noisy operation, water leaks, and ice/water dispenser issues) and gives step-by-step diagnostic and repair instructions. Follow the numbered steps for diagnosing each symptom and the recommended repair actions. 1) Refrigerator not cooling (or freezer cold but fridge warm) - Check basics: Confirm power is on, temperature settings (fridge 37°F / 3°C, freezer -2 to 0°F / -18°C). Make sure vents inside fridge/freezer aren’t blocked by food. - Inspect condenser coils: Unplug the fridge, pull it away from the wall, and clean the condenser coils and area around the compressor. Dirty coils reduce cooling efficiency. - Check condenser fan motor: With power off, access the condenser fan near the compressor. Manually spin the fan — it should spin freely. If seized or won’t run when powered, replace the condenser fan motor (common part DA31-00006D). - Check evaporator fan motor: If the freezer is warm or there’s no air flow into the fridge, the evaporator fan inside the freezer evaporator cover may be faulty. Remove the evaporator cover with power off and inspect for heavy frost and fan operation. Replace evaporator fan motor if it doesn’t run (common part DA31-00020A). - Listen to the compressor and check start relay: If the compressor tries to start and clicks repeatedly, the start relay/overload may be bad. Unplug and test/replace the start relay/overload (common part DA47-00055A). - Check defrost system: If the evaporator has heavy frost/ice, the defrost heater, defrost thermostat (NTC), or defrost control may have failed. Remove the evaporator cover, visually inspect for frost pattern, and test the defrost heater for continuity; replace faulty heater (example part DA47-10107A) or defrost thermistor. - Check damper control: If freezer is cold but the fridge is warm and fans/compressor are OK, the fresh air damper that controls airflow to the fridge may be stuck. Inspect and replace damper assembly if necessary (DA97-08116A). - When to call a pro: If compressor runs but temperatures won’t recover after fan/defrost/damper checks, there may be a sealed-system refrigerant leak or compressor failure — requires certified technician. 2) Frost or ice buildup on evaporator - Cause: Defrost heater, defrost thermostat, or defrost control failure, or blocked drain causing water freeze. - Steps: Unplug fridge and remove evaporator cover. If heavy ice present, manually defrost (allow to melt or use hair dryer with care). Test defrost heater for continuity and replace if open. Check defrost thermostat (NTC) resistance curve and replace if out of spec. Clear and flush the drain tube and pan. 3) Ice maker not producing or dispenser not working - Steps: Verify water supply valve is open and water line is pressurized. Inspect water filter — if old or clogged, replace. Test inlet water valve for continuity and that it opens when dispenser/ice maker calls for water. Check ice maker module for harvest cycle and water fill: many Samsung ice makers are replaceable assemblies (DA97-08006A). For dispenser not dispensing ice, check auger motor and switch. 4) Water leaking or puddle under fridge - Steps: Inspect door gaskets for seal issues and replace if damaged. Check the defrost drain for clogs (remove plug at drain pan and pour water to confirm flow). Ensure drain pan is seated correctly and not cracked. Check water line connections and filter housing for leaks. 5) Unusual noises (buzzing, rattling, gurgling) - Steps: Identify noise source: compressor area (compressor or start device), evaporator fan (squeal/grind), or condenser fan (rattle). Secure loose parts, replace worn fan motors, and replace start relay/overload if the compressor cycles loudly. Gurgling is often normal refrigerant flow; loud hissing or knocking that persists should be checked by a technician. Safety note: Always unplug the refrigerator before performing any internal inspections or repairs. Replacing sealed-system components (compressor, refrigerant) must be done by certified HVAC/refrigeration technicians. Use protective gloves and eye protection when working with sharp sheet metal and components.
Common Symptoms
Fridge not cooling while freezer is cold, heavy frost on evaporator, ice maker or water dispenser not working, water under fridge, loud or unusual noises.
Common Causes
- Dirty condenser coils or blocked airflow
- Failed evaporator or condenser fan motor
- Defrost system failure (heater/thermostat/control)
- Faulty start relay/overload or compressor issue
- Damaged air damper/actuator or control board problems
- Clogged defrost drain or water supply issues for ice maker

Helpful Repair Tip
To confirm a bad fan motor, open the freezer door and press the door switch so the fridge is running; listen for airflow. If the evaporator fan doesn't run, remove the evaporator cover and try to spin the fan blade by hand — if it won’t spin freely or the motor doesn’t run when powered, replace that fan motor (evaporator fan DA31-00020A).
Frequently Asked Questions
My freezer is cold but the refrigerator compartment is warm. What should I check first?
First check that internal vents between freezer and fridge aren't blocked by food. Next, verify the evaporator fan runs when the doors are closed — if the fan isn't running, replace it. If the fan is fine, inspect the fresh-air damper/actuator that allows cold air into the fridge. If those check out, check for heavy frost on the evaporator (defrost failure) or call a technician for sealed-system issues.
How do I reset my Samsung NX58H9500WS/AA refrigerator?
You can do a basic reset by unplugging the refrigerator for 60 seconds or switching off the circuit breaker for 60 seconds, then restoring power. For some control issues, use the control panel options (check your manual) to reset or run diagnostic modes. If problems persist after a power cycle, further component-level diagnostics are needed.
