Samsung refrigerator not cooling
Protect food first, preserve displayed codes, then check settings, airflow, doors and recovery timing.
What this guide covers
Symptoms: Refrigerator/freezer not cooling
This guide follows a structured decision tree built from manufacturer troubleshooting information. It does not assume that the most commonly replaced part is the failed part, and it does not show an exact-fit replacement part unless model compatibility has been independently verified.
Continue this exact diagnostic
Start with the right cooling symptom
Use this page when the fresh-food section is too warm, with or without a warm freezer. If the concern is limited to the freezer section, compare the freezer-warm path before choosing.
The reviewed path records an exact display first, distinguishes partial cooling from no cooling, and then keeps power, mode, settings, clearance, airflow, seals, and any bounded power-cycle observation separate.
- Protect food firstUse a measured temperature when available; touch, lights, sound, or elapsed troubleshooting time cannot certify food as safe.
- Record what is actually warmSeparate freezer-only warming, fresh-food warming, and both compartments warming. Preserve Not sure instead of guessing.
- Keep the model boundaryThis public guide stays at its stated manufacturer scope. The interactive guide checks the entered model before applying any verified model-family procedure.
How to check without guessing
General manufacturer guidance. Exact-model controls and procedures have not been verified for this guide.
Protect food before troubleshooting: keep doors closed; use a refrigerator/freezer thermometer or another known measured temperature when available; touch alone, lights, compressor sound, or elapsed troubleshooting time cannot certify food as safe. Move food to verified cold storage if a safe temperature cannot be maintained. Never taste food to decide. Use the FoodSafety.gov chart when time and temperature are known; a closed refrigerator during an outage generally protects food for up to four hours, and refrigerated perishables above 40°F/4°C for more than two hours need the item-specific chart. Stop for a damaged cord, hot outlet, burning odor, sparking, water near electrical parts, or a recurring breaker trip. Use only a safely accessible normal plug or one ordinary breaker reset. Do not remove panels, enter service mode, bypass controls, move the appliance, perform live tests, or attempt internal fan, defrost, compressor, refrigerant, or sealed-system work.
Record any code before a reset
Record the exact error or blinking display before any reset. A code takes precedence over power cycling; not every Samsung model displays every code.
Use the exact displayed code first
Preserve the exact display and return to code entry for code-specific safety and routing before clearing or power cycling. This result does not diagnose a component.
Separate partial cooling from no cooling at all
Use measured compartment temperatures or a clear sustained cooling observation. Air feel immediately after opening a door is not enough. Yes means at least one compartment is demonstrably cooling; No means neither is cooling.
Check stable external power
For no cooling at all, lights or a panel response are only power clues, and Sabbath mode can affect visible indications. Confirm the normal wall supply without assuming cooling is present.
The power condition needs qualified electrical help
Use only an undamaged safely accessible plug or one normal breaker reset. Damage, heat, odor, sparking, water, a recurring trip, or unsafe access stops for qualified electrical help.
Check for Cooling Off or Demo mode
Visible OF OF, O FF, OFF OFF, or scrolling temperature bars are general Cooling Off/Demo clues. RF23A9671SR/AA identity does not verify an exact button sequence.
Restore normal cooling mode
Use matching model instructions to restore normal cooling. Do not guess a button sequence, enter service mode, or treat a cleared display as proof of cooling.
Separate settings from incomplete stabilization
Separate a wrong setpoint from an incomplete wait after a setting change. Answer Yes only when settings are appropriate and the documented stabilization window has elapsed or the temperature is demonstrably recovering.
Correct the setting and use the separate stabilization window
Use the normal owner control described by matching instructions. Samsung says an ordinary setting change can take up to 28 hours; this is separate from the power-cycle observation.
Check visible exterior and interior clearance
Check only visible exterior/interior space and obstructions. Samsung gives general two-inch guidance, but it is not verified as exact RF23A9671SR/AA installation documentation.
Installation conditions need qualified attention
Remove only a safely reachable loose obstruction. Appliance movement, leveling, built-in/cabinet changes, or hidden clearance needs an installer.
Check room and heat-source conditions
Check actual room conditions and nearby heat sources. If the location cannot be safely corrected without movement or installation work, preserve the observation for an installer.
Installation conditions need qualified attention
Arrange qualified installation help for an unsuitable location or required movement. Do not infer an internal cooling failure from the location alone.
Check visible interior airflow
Inspect visible vents in both compartments and food loading. Yes means visible openings are clear and circulation space exists; hidden airflow is Not sure.
Restore visible interior airflow
Move food away from visible vents and reduce crowding without removing covers. Keep doors closed during the observation.
Check every door and visible seal
Inspect every applicable door and visible gasket. Use the paper-resistance observation only where it can be done safely. A damaged/warped seal, misalignment, or repeated failed paper observation needs service, not a guessed gasket purchase.
Restore accessible door closure and seal contact
Remove visible obstructions and clean accessible seals with the manufacturer’s mild method. Do not disassemble or heat a gasket. Persistent damage or alignment trouble goes to service.
Use one documented two-minute power cycle
Only after recording any code and completing safe external checks, disconnect power for two minutes through a normal accessible plug or breaker, restore settings, then observe measured temperature for up to three hours for a downward trend. Do not require Power Cool. This is not the separate up-to-28-hour setting stabilization window.
Cooling remains unresolved — prepare a service brief
Record whether neither or only one compartment cooled, measured temperatures, the exact display/code, power/mode/settings, elapsed 28-hour or three-hour observation as applicable, clearance/environment, airflow/seal checks, failed corrections, and unavailable checks. No compressor, fan, sensor, control, defrost, refrigerant, or sealed-system component has been diagnosed.
Safe troubleshooting sequence
Start with the observations and external checks that can be verified without opening energized assemblies. The interactive version asks these in order and changes the path based on your answers.

Appliance Verdict stops before energized electrical testing, gas-system work, sealed-system work, and other checks that can create unnecessary risk. A technician can use the model, issue, and completed checks from the interactive diagnostic as a starting point.
Repair or replace?
A diagnosis and a repair decision are different questions. Once you have a real repair quote, compare the total repair cost with the all-in price of a comparable replacement. Warranty or protection-plan coverage, appliance age, reliability history, efficiency, and likely future repairs can all matter. Appliance Verdict's interactive result includes a transparent cost comparison rather than a black-box replacement recommendation.
