Understanding the Problem
This guide covers the most common problems owners see with the Samsung RF28HDEDTSRAA French-door refrigerator: poor cooling, freezer or fridge too warm, ice maker or water dispenser failures, excessive frost, unusual noises, and door sealing issues. Below are practical, step-by-step diagnostics and repair actions for each issue so you can isolate the failing part and fix it. 1) Refrigerator or Freezer Not Cooling Properly 1. Verify settings and temps: Ensure fridge set to 37°F (3°C) and freezer to 0°F (-18°C). Give 24 hours after changing settings. 2. Check airflow/vents: Remove items blocking vents inside fridge/freezer. Restricted airflow causes warm compartments. 3. Clean condenser coils: Unplug unit, pull refrigerator out, remove kickplate and clean dust from condenser coils and fan with a brush/vacuum. Reconnect power. 4. Check condenser fan: With power on, listen for fan near compressor. If fan doesn’t run, unplug and test for continuity; replace if failed. 5. Check evaporator fan (inside freezer): Open freezer door, run fridge, listen for evaporator fan. If noisy or not running, remove back panel in freezer (after removing shelves) and test motor for continuity; replace fan motor if dead. 6. Inspect evaporator for frost build-up: Excessive frost indicates defrost failure. Defrost components to check: defrost heater, defrost thermostat (thermistor), and defrost control. Test continuity on heater and thermostat; replace failed component. 7. Test compressor and start relay: If compressor doesn’t run or makes clicking noise, unplug and test start relay (or have tech test). A bad start relay means compressor won’t run reliably. 8. Sealed system leak: If compressor runs but cooling is poor and evaporator is warm, sealed system fault (refrigerant loss) is likely — sealed-system repairs require certified HVAC/R tech. How to fix (practical): Clean coils and replace any non-running fan motors or failed defrost components yourself if comfortable. For start relays, purchase a matched relay and follow replacement steps on the service manual. For sealed-system issues, call a certified technician—do not attempt compressor or refrigerant work. 2) Ice Maker Not Making Ice / Low Ice Production 1. Confirm ice maker is on and the arm (if equipped) or the harvest cycle is active. 2. Check water supply and shutoff valve: Ensure valve to fridge is open and water line not kinked. 3. Replace clogged/old water filter: A clogged filter reduces water flow. Replace with OEM or approved replacement (e.g., Samsung DA29-00020B or compatible filter) and run several dispenser cycles. 4. Inspect water inlet valve: With power off, check for leaks and test coil continuity. Replace valve if it does not open or has no continuity. 5. Test ice maker assembly: Manually cycle or use diagnostics (if accessible) to trigger fill. If motor doesn’t run or harvest heater is bad, replace ice maker assembly. 6. Check freezer temperature: If freezer warmer than ~0°F (-18°C) ice production will be poor—trace back to cooling troubleshooting above. How to fix: Replace water filter, clear/fix water line, replace inlet valve or ice maker assembly if proven faulty. 3) Water Dispenser Not Working or Slow Flow 1. Check water filter: Replace if older than 6 months or if flow is slow. 2. Test dispenser with cup and listen: If humming but no water, inlet valve may be stuck. 3. Inspect water line for kinks or frozen section: If line inside freezer door is frozen, warm it (unplug and let thaw) and consider insulating/relocating line. 4. Test/replace water inlet valve if it does not open electrically. 4) Excessive Frost or Ice Build-Up in Freezer 1. Confirm door seals: Dirty/damaged gasket or misaligned door can allow moist air in. 2. Check defrost system: The defrost heater, defrost thermostat, and defrost control often cause frost build-up when they fail. Remove freezer evaporator cover and test these parts for continuity. Replace faulty part(s). 3. Ensure proper thermostat/thermistor readings: Faulty temperature sensors can prevent defrost cycles from running. 5) Unusual Noises (Buzzing, Clicking, Rattling) 1. Identify noise source: Compressor area (back) vs. fan area (condenser or evaporator) vs. ice maker (front). 2. Fan noise: If noise changes with door open/closed or temp, likely evaporator or condenser fan. Replace noisy fan motor. 3. Clicking every few minutes: Could be start relay trying to start compressor; test/replace relay. 4. Ice maker noises: Clicking or whining at ice maker may indicate gear motor wear—replace ice maker assembly. 6) Door Won’t Seal or Door Alignment Problems 1. Inspect gasket for tears, debris, or cold gaps. Clean gasket with warm soapy water; replace if damaged. 2. Check door alignment and hinge: Tighten hinge bolts or adjust leveling feet so doors seal evenly. Safety note: Always unplug the refrigerator and shut off the water supply before performing electrical or water-line work. Use a multimeter to test components only if you are comfortable and know how to test live circuits safely. Do not attempt sealed-system repairs (compressor, refrigerant) — those require EPA certification and specialized equipment.
Common Symptoms
Fridge or freezer warm; poor ice production; no water from dispenser or slow flow; excessive frost in freezer; loud noises; poor door seal.
Common Causes
- Dirty condenser coils or failed condenser/evaporator fan motors
- Clogged water filter, faulty inlet valve, or blocked water line
- Defrost system failure (heater/thermostat) or sealed-system refrigerant loss

Helpful Repair Tip
Start with the simple checks: replace the water filter (DA29-00020B) and clean the condenser coils. Then listen for the evaporator fan running with the freezer door open—if the evaporator fan is dead while the compressor runs, replace that fan motor next.
Frequently Asked Questions
How do I reset the Samsung RF28HDEDTSRAA?
A basic reset is done by unplugging the refrigerator for 60 seconds or switching the breaker off for 60 seconds, then restoring power. This clears many control board glitches. For persistent errors, consult the service code in the user manual or call a technician.
Do I need a technician to replace the compressor or fix a refrigerant leak?
Yes. Compressor and refrigerant (sealed system) repairs require certified HVAC/R technicians with the proper tools and EPA certification. Attempting sealed-system repairs without certification is unsafe and often illegal.
