Understanding the Problem
Brief overview: NED5800HWO is a refrigerator model that commonly shows the same symptoms most refrigerators do — poor cooling, frosting in the freezer, noisy operation, leaks, or ice/water dispenser failures. Below are the likely causes for each major symptom and step-by-step diagnostic and repair instructions so you can pinpoint and fix the problem. 1) Refrigerator Not Cooling (fridge warm, freezer cold or both warm) 1. Check basic settings: confirm temperature controls are set correctly and the unit is plugged in. 2. Listen for the compressor and condenser fan: if compressor runs and condenser fan spins, move to airflow/evaporator checks. If the compressor is quiet and there is only occasional clicking, suspect start relay/overload or a failed compressor. 3. Clean condenser coils and ensure proper airflow: unplug the fridge, remove kick plate, vacuum dust and debris from coils and fan. Put back and test for temperature change over 24 hours. 4. Check condenser fan motor and evaporator fan motor: with the fridge plugged in, open the freezer and listen for the evaporator fan. If it doesn't run when the compressor runs, replace the evaporator fan motor. Check the condenser fan at the back bottom; if it’s not spinning, replace or test the motor. 5. Test start relay/overload: unplug the fridge, remove the relay from the compressor, check for burnt smell, and test with a multimeter (continuity/ohms). Replace the start relay/overload if suspicious. 6. Check evaporator coil frost pattern: heavy frost on coil suggests defrost failure (heater, thermostat/DFR, or control board). No frost at all while compressor runs can indicate refrigerant leak or sealed system failure — this requires a certified tech. 7. If you confirm the compressor runs but there is no cooling and the sealed system is suspected, call a professional — sealed system repair needs special tools and refrigerant handling. 2) Freezer Frost Build-up / Ice in Evaporator 1. Symptom: thick frost/ice on evaporator coil, poor cooling, freezer very cold and fridge warm. 2. Check door seals and door closing: damaged gaskets let moisture in; replace bad gasket. 3. Verify the defrost system: enter diagnostics or manually advance to defrost; inspect defrost heater and defrost thermostat (NTC/DFT) for continuity with a multimeter. If defrost heater or thermostat is open, replace the faulty part. 4. Check defrost control or main control board if heater and thermostat are good but the heater never runs during defrost cycle. 5. After replacing defrost components, manually defrost the coil (unplug and let melt or use hot water) before powering up to verify normal operation. 3) Ice Maker or Water Dispenser Not Working 1. Confirm water supply: ensure shutoff valve is open and line to fridge has pressure. Check for kinks in the water line. 2. Inspect inlet water valve: if no water to ice maker/dispenser, test the solenoid valve for 120V when dispenser/ice maker calls for water. Replace valve if it fails to open or has no continuity. 3. Check ice maker module: manually cycle or enter diagnostics to run the ice maker. If motor/harvest components do not run, replace the ice maker assembly or module. 4. Replace clogged inline filter if equipped (replace every 6–12 months) and purge air from the line after replacement. 4) Leaks or Water Pooling Under Fridge 1. Check the defrost drain: clogs cause water to run onto the floor. Locate the drain at the back of the freezer evaporator area, clear blockages with warm water or a pipe cleaner, and flush the drain to the drain pan. 2. Inspect water line fittings and inlet valve for leaks and tighten or replace as needed. 3. Verify drain pan position — sometimes the pan is dislodged. 5) Excessive Noise (clicking, humming, rattling) 1. Identify the source: compressor area (back bottom), evaporator compartment, or doors/hinges. 2. Clicking or a humming that stops and restarts often points to a failing start relay or overload. Replace the relay if testing shows failure. 3. Rattling or vibration: check and tighten panels, level the cabinet, secure loose brackets, and inspect condenser/evaporator fan motors for worn bearings. General step-by-step repair tips (applies to most parts replacements) 1. Safety first: unplug the refrigerator or shut off power at the breaker before any inspection or repair. 2. Remove access panels (condenser/fan/compressor area or evaporator cover) to visually inspect components. 3. Test electrical components with a multimeter for continuity or correct resistance values (thermistors typically 5–30kΩ depending on temperature; motor windings should show low resistance but not open). 4. Replace the faulty component with an OEM- or compatible-quality part, following manufacturer instructions for mounting and wiring. 5. Reassemble panels, restore power, and monitor operation for 24–48 hours to confirm the repair. Safety note: always disconnect power before working on electrical parts. Refrigerant-handling and sealed-system repairs must be performed by a licensed HVAC/refrigeration technician. Wear gloves and eye protection when handling sharp sheet metal and coils.
Common Symptoms
Fridge not cooling or uneven cooling, freezer frosting/ice buildup, ice maker or water dispenser not operating, leaks under fridge, loud or unusual noises.
Common Causes
- Clogged condenser coils or poor airflow
- Failed evaporator or condenser fan motor
- Defrost system failure (heater, thermostat, control)
- Faulty start relay/overload or compressor issues
- Water inlet valve or clogged water filter
- Damaged door gasket allowing moisture infiltration

Helpful Repair Tip
Use the fridge's diagnostic mode (if available) to run the evaporator fan, condenser fan, ice maker, and defrost heater tests one at a time — it tells you which component fails before you tear anything apart.
Frequently Asked Questions
How do I find the exact replacement part for NED5800HWO?
Take the full model number (NED5800HWO) from the tag inside the fridge and use it on the manufacturer's parts lookup page or a reputable parts retailer. Match the drawing/part number to the part you need and confirm compatibility before ordering. Many parts are model-specific, so don’t substitute without checking.
Can I repair these issues myself or do I need a technician?
You can do DIY repairs for cleaning coils, replacing gaskets, changing water filters, clearing the defrost drain, or swapping fan motors and inlet valves if you are comfortable with basic hand tools and multimeter checks. Call a licensed appliance technician for sealed-system work (compressor/refrigerant), high-voltage board-level repairs if unsure, or if diagnostics point to a failed compressor.
