Samsung Refrigerator Error Codes: Complete List with Fixes

Samsung refrigerators — from the Family Hub with its 21.5-inch touchscreen to the Bespoke 4-Door Flex and the classic French Door RF28 series — pack serious technology into your kitchen. But when something goes wrong, that same technology communicates through cryptic error codes on the display panel. This guide covers every Samsung refrigerator error code, explains what triggered it, and walks you through the fix — whether that means a 30-second button press or a professional repair.

How Samsung Refrigerator Error Codes Work

Samsung refrigerators continuously monitor over a dozen sensors: freezer temperature, fridge temperature, defrost circuits, fan motors, compressor current, ice maker position, and more. When a reading falls outside the acceptable range, the control board displays an alphanumeric code on the front panel.

Important: Samsung uses a dual-display system on many models. The code may appear on the exterior temperature display or on the Family Hub screen. Some codes disappear after a power cycle, so photograph the display before troubleshooting.

To reset most Samsung refrigerator error codes:

1. Press and hold the Power Freeze and Power Cool buttons simultaneously for 8–10 seconds.
2. If the code persists, unplug the refrigerator for 5 minutes, then restore power.
3. If the code returns within 24 hours, the underlying issue needs repair.

Samsung Forced Defrost Mode (useful for ice-related codes): Hold the Freezer and Fridge buttons simultaneously for 8 seconds. Then press the Freezer button until "Fd" appears. The unit will run a forced defrost cycle for about 20 minutes.

1E — Freezer Room Sensor Error

The freezer temperature sensor (thermistor) is sending abnormal readings or has lost connection with the control board.

Common causes:

• Sensor connector corroded or disconnected (Samsung DA32-10109W)
• Thermistor wire harness pinched behind the rear freezer panel (Samsung DA96-00942A)
• Short circuit in the sensor itself
• Control board voltage regulator fault (rare, but causes both 1E and 2E simultaneously)

How to fix:

1. Unplug the refrigerator and wait 5 minutes. Restore power to see if the code clears — a transient spike can trigger a false 1E.
2. Pull the unit from the wall and remove the rear access panel. Locate the freezer thermistor near the evaporator coils behind the rear freezer panel.
3. Inspect the two-wire connector for corrosion or loose pins. A corroded connector is the most common cause — a $3 connector fix saves a $120 sensor replacement.
4. Use a multimeter to test the thermistor: at 32 degrees F it should read approximately 5 k-ohm; at 77 degrees F approximately 12 k-ohm. Out-of-range readings confirm a failed sensor.
5. Replace the freezer room sensor assembly (Samsung DA32-10109W or DA32-10109V) if readings are abnormal.

Part cost: Freezer thermistor $15–$30. Wire harness connector kit $8–$15. Professional repair $150–$300 total.

2E — Fridge Room Sensor Error

The fresh food compartment thermistor is reading incorrectly or the circuit is open.

Common causes:

• Sensor malfunction after extended power outage
• Wiring issue where the harness passes through the door hinge area
• Thermistor reads open (OL on multimeter) or zero ohms (shorted)

How to fix:

1. Unplug for 5 minutes and restore power — transient electrical spikes can trigger false 2E codes.
2. Remove the fresh food section rear panel (4–6 Phillips screws). The fridge thermistor is clipped to the evaporator housing or near the air inlet duct.
3. Test with a multimeter: resistance should be approximately 5 k-ohm at 32 degrees F. OL or zero reading means replacement is needed.
4. Replace with Samsung DA32-10109W. Reinstall the rear panel and monitor for 24 hours.

Diagnostic tip: If both 1E and 2E appear together, suspect the main control board rather than both sensors — simultaneous dual-sensor failure is extremely rare, but a board-level voltage regulator fault is not.

Part cost: Fridge thermistor $15–$30. Professional repair $150–$280 total.

4E — Freezer Defrost Sensor Error

The defrost bi-metal thermostat or defrost sensor has failed, meaning the automatic defrost cycle cannot properly regulate.

Common causes:

• Defrost bi-metal thermostat failed open (Samsung DA47-00243B)
• Defrost sensor with thermal fuse blown (Samsung DA47-00301R)
• Wiring damage where the harness passes through foam insulation

How to fix:

1. Unplug and remove all items from the freezer. Remove the rear freezer panel (6–8 screws plus clips) to expose the evaporator coils.
2. Locate the defrost sensor — a small oval device with two wires mounted on or near the evaporator.
3. Test for continuity when cold (below 30 degrees F): should show near 0 ohms. An open circuit when cold means replacement is needed.
4. Check both the sensor and the thermal fuse — Samsung uses a combination part on many models, and a blown fuse triggers 4E even with a working sensor.

Part cost: Defrost bi-metal thermostat (DA47-00243B) $10–$25. Defrost sensor with fuse (DA47-00301R) $15–$35. Professional repair $175–$325.

21E — Freezer Fan Error

The evaporator fan in the freezer compartment is not running or is obstructed.

Common causes:

• Ice encasing the fan blades from a failed defrost cycle
• Freezer fan motor bearing failure (Samsung DA31-00146E)
• Fan blade cracked from ice contact (Samsung DA31-00242A)
• Door gasket gap allowing humid air in, causing repeated icing

How to fix:

1. Open the freezer and listen — grinding or clicking means ice is hitting the blades.
2. Unplug, empty the freezer, and remove the rear panel to access the fan. Use a hair dryer on low to melt ice carefully.
3. Spin the fan blade by hand — it should rotate freely. Stiff or seized rotation means the motor bearings have failed.
4. Check door gaskets with the dollar-bill test: close the door on a bill, and if it slides out easily, the seal is worn (model-specific DA97-series gasket).

Diagnostic tip: A 21E that recurs every few weeks points to a defrost system problem, not the fan. The fan ices over because the defrost cycle is not clearing frost completely — check the defrost heater and thermostat even if the fan works after manual defrost.

Part cost: Fan motor (DA31-00146E) $25–$50. Fan blade $10–$20. Professional repair $150–$300.

22E / 22C — Fridge Fan Error

The fresh food compartment circulation fan is not operating, causing uneven or no cooling in the fridge section while the freezer works fine.

Common causes:

• Ice buildup on the fridge-side fan (dual-evaporator models like RF28 series)
• Fan motor failure (Samsung DA31-00146J)
• Fan connector not fully seated on the main control board

How to fix:

1. Listen at the top-rear of the fresh food compartment behind the vent panel. No sound means no airflow.
2. Remove the rear panel inside the fresh food section. Check for ice buildup around the fan.
3. Test the fan motor by applying 12V DC to the leads. No spin means replacement is needed.
4. Verify the fan connector is fully seated and no wires are pinched by the panel.

Part cost: Fridge fan motor (DA31-00146J) $25–$50. Professional repair $150–$275.

33E — Ice Pipe Heater Error

The fill tube heater that prevents the ice maker water line from freezing has failed.

Common causes:

• Fill tube heater burned out (Samsung DA97-15217A or DA47-00425A)
• Wiring connection fault at the main board (2-pin white plug, lower-right section)
• Freezer temperature set below -2 degrees F, overwhelming the heater

How to fix:

1. Locate the ice maker water fill tube entering the freezer from the back, typically through the left side wall.
2. Remove the fill tube housing cover and inspect the heater wire wrapped around the tube.
3. Test for continuity — should read 200–800 ohms depending on model. Open reading means the heater is burned out.
4. Replace the fill tube heater assembly if the continuity test fails.

Part cost: Fill tube heater assembly $20–$45. Professional repair $175–$325.

84E — Compressor / Rotor Lock Error

The inverter compressor cannot start or the rotor is mechanically locked. This is the most critical — and most expensive — Samsung refrigerator error.

Common causes:

• DC compressor failure (locked rotor windings)
• Inverter board fault (Samsung DA92-00111B) — fails almost as often as the compressor at one-third the cost
• Compressor start relay and overload protector failure (Samsung DA35-00099A)
• Power surge damage to compressor windings

How to fix:

1. Unplug for 10 minutes and restore power — Samsung inverter compressors can recover from surge-induced 84E.
2. Listen after powering on: clicking followed by silence every few minutes means the compressor tries to start but the rotor is locked.
3. Check the start relay by removing the relay cover on the compressor — shake it gently. Rattling indicates a failed relay ($15–$25 part).
4. Measure compressor winding resistance between the three pins (common, start, run). Readings should match the label specifications. Open or shorted windings confirm compressor failure.
5. Test the inverter board first before quoting compressor replacement — it fails almost as often and costs one-third the price.

Part cost: Inverter board $80–$150. Compressor start relay $15–$25. Compressor replacement $400–$800 (requires EPA 608 certification for R-600a refrigerant handling).

85C — Low Voltage Warning

The power supply voltage has dropped below the acceptable range for Samsung refrigerators (requires 110–120V AC).

Common causes:

• Outlet voltage below 100V (Sacramento homes built before 1970 commonly have under-gauge wiring)
• Extension cord or power strip causing voltage drop under compressor startup load
• Overloaded circuit during peak AC usage (summer afternoons)

How to fix:

1. Measure outlet voltage with a multimeter — below 100V triggers the 85C code.
2. Plug directly into a wall outlet (never use extension cords for refrigerators).
3. If voltage is low, check the breaker panel for an overloaded circuit. A dedicated 15A or 20A circuit is recommended.

Part cost: Typically no parts needed — this is a power supply issue. Electrician visit for dedicated circuit: $150–$300.

88 88 / 83E / 85E / 86E — Power or Communication Error

All display segments illuminate simultaneously, indicating the main control board lost communication with the display board.

Common causes:

• Power surge or brownout
• Ribbon cable between main board and display board loose or damaged
• Main control board damaged by surge (Samsung DA92-00384B)
• Display panel board fault (Samsung DA92-00368B)

How to fix:

1. Unplug for at least 2 minutes (not just 1) to fully discharge capacitors, then restore power.
2. If "88 88" appears immediately, try a different outlet to rule out a damaged wall circuit.
3. Disconnect and reconnect the display panel ribbon cable from the main board — in about 40% of cases, simply reseating this cable fixes it permanently.
4. Check the power cord for damage, burn marks, or loose prongs.

Part cost: Ribbon cable reseat: free. Main control board (DA92-00384B) $100–$200. Display board (DA92-00368B) $80–$150.

PC ER / PC CH — Panel Communication Error

The main control board and display board cannot communicate. Common on Family Hub models where the Wi-Fi module can interfere with the board-to-board communication bus.

Common causes:

• Board failure or firmware glitch
• Ribbon cable damage or corrosion
• Wi-Fi module interference (Samsung service bulletin ASC-20190312-001 for Family Hub models)

How to fix:

1. Power cycle for 5 minutes — PC ER can result from firmware glitches.
2. On Family Hub models, try disconnecting the Wi-Fi antenna before replacing boards.
3. Inspect ribbon cable connections at both ends for secure seating.
4. Replace the main control board first (more common failure point).

Part cost: Communication ribbon cable (DA96-00764A) $15–$30. Main control board $100–$200. Professional repair $250–$500.

OF OF / O FF — Cooling Off (Demo Mode)

This is not an error — the refrigerator is in shop demo mode where the display works but the compressor does not run. Food will spoil if not caught quickly.

How to fix:

1. Press and hold Energy Saver + Power Freeze for 3–5 seconds until you hear a chime.
2. On newer models (2020+): hold the Freezer and Fridge temperature buttons for 5 seconds.
3. If button combinations fail, unplug the unit, wait 2 minutes, then plug in while holding the Energy Saver button for 5 seconds.

Part cost: $0 — no parts needed.

39E / 39C — Ice Maker Sensor Error

The ice maker optical sensor or wiring has a fault.

Common causes:

• Frost on the optical sensor lens (wipe with dry cloth — resolves about 30% of cases)
• Loose ice maker wiring harness connector
• Ice maker assembly failure (Samsung DA97-15217D)

How to fix:

1. Remove the ice bucket and check for frost, ice jams, or debris around the sensor.
2. Unplug and reconnect the ice maker wiring harness — a loose connection is the most common cause.
3. Press and hold the test button for 3 seconds to run a test cycle. Listen for motor engagement and water valve opening.
4. If the test cycle fails, the ice maker assembly likely needs full replacement.

Part cost: Ice maker assembly (DA97-15217D) $80–$150. Water inlet valve (DA62-04472A) $30–$50. Professional repair $200–$400.

76C — Water in Autofill Compartment

A moisture-detection alert specific to Samsung models with the Autofill pitcher feature.

Common causes:

• Spilled water or condensation in the Autofill tray
• Cracked Autofill pitcher (Samsung DA97-13780A)
• Water dispenser nozzle dripping

How to fix:

1. Remove the Autofill pitcher and wipe all moisture from the tray and sensor area.
2. Check the pitcher for cracks — a cracked pitcher leaks slowly into the tray.
3. Clean the sensor contacts with a dry cloth to remove mineral deposits.

Part cost: Autofill pitcher replacement (DA97-13780A) $30–$60. Professional repair $75–$175.

Samsung SmartThings Refrigerator Diagnostics

Samsung refrigerators with Wi-Fi connectivity offer remote diagnostics through the SmartThings app:

1. SmartThings App Diagnosis: Open the SmartThings app, select your refrigerator, and tap Device Care then Report an Issue. The app pulls error history and sensor data directly from the unit and can email a diagnostic report.

2. Forced Defrost Mode: Hold the Freezer and Fridge buttons simultaneously for 8 seconds. Press the Freezer button until "Fd" appears. This forces a 20-minute defrost cycle — essential for diagnosing ice-related errors (21E, 22E, 40E, 33E).

3. Self-Diagnosis Mode: On Family Hub models, navigate to Apps > Samsung > Fridge Manager > Self Diagnosis. The unit runs a comprehensive check of all sensors, fans, and the compressor, then displays a pass/fail summary.

4. Service Mode: On non-Family Hub models, press and hold Energy Saver + Alarm for 5 seconds to enter service mode. This displays real-time sensor readings — freezer temp, fridge temp, defrost heater status, fan RPM, and compressor current.

Frequently Asked Questions

Q: Why does my Samsung refrigerator show "88 88" after a power outage? A: The "88 88" display means the communication link between the main board and display board was disrupted. Unplug for 2 full minutes, then restore power. If it persists, reseat the ribbon cable connecting the two boards — this resolves about 40% of cases without any parts.

Q: How do I get my Samsung refrigerator out of demo mode? A: Hold Energy Saver + Power Freeze for 3–5 seconds on standard models, or Freezer + Fridge buttons for 5 seconds on newer models. Demo mode disables all cooling while keeping lights and the display active, so food will spoil if not corrected quickly.

Q: My Samsung fridge is warm but the freezer works fine — what code should I look for? A: This pattern typically points to a 22E (fridge fan error) or a damper issue. The damper controls airflow from the freezer to the fridge. If the fridge fan runs but no cold air flows, the damper motor has likely failed and needs replacement.

Q: Is the Samsung refrigerator compressor covered by warranty? A: Samsung provides a 1-year full parts and labor warranty and a 10-year limited warranty on the compressor (parts only, no labor). The inverter board, which fails almost as often, is only covered by the 1-year warranty. Keep your purchase receipt.

Q: How often should I clean the condenser coils on my Samsung refrigerator? A: Every 6–12 months. Dirty coils force the compressor to work harder, increasing energy consumption and shortening compressor life. On Samsung French Door models, the coils are underneath — pull off the front kick plate and use a coil brush or vacuum to clean.

When to Call a Professional

Some Samsung refrigerator error codes require specialized tools and expertise:

• 84E (compressor/rotor lock) — Involves sealed refrigerant system (R-600a) requiring EPA 608 certification. The most expensive refrigerator repair at $400–$800.
• PC ER / C-10 (communication errors) — Control board diagnosis and replacement requires electronic expertise and model-specific firmware.
• Repeated 1E/2E with normal sensor readings — May indicate main control board failure requiring board-level diagnosis.
• 40E recurring after manual defrost — The defrost system has a component failure that will cause ice to return within 2–3 weeks without part replacement.
• Any refrigerant leak or hissing sound from the sealed system — Requires certified HVAC technician with proper recovery equipment.

A professional technician can access Samsung service mode to read detailed sensor data, error history, and compressor runtime statistics that are not available through the consumer SmartThings app.
