Samsung refrigerator fan errors (21E, 22E, ER FF) are caused by frozen fan blades in 90% of cases. Run forced defrost mode: press Power Freeze + Lighting until display changes, then press Lighting until “Fd” appears. Let the 30-60 minute cycle melt the ice. If errors return frequently, the defrost system needs repair.
| Error Code | 21E / 22E / ER FF (also: 21C, 22C, 23E, 23C, FF) |
|---|---|
| Meaning | Evaporator or condenser fan not operating |
| Difficulty | Medium |
| Time to Fix | 30-90 minutes |
| Tools Needed | Phillips screwdriver, Hair dryer, Towels |
| DIY Fixable | Yes |

Fan error codes on Samsung refrigerators indicate the evaporator or condenser fan has stopped providing proper rotation feedback to the control board. In most cases, the fan is physically blocked by ice—a problem that forced defrost mode can resolve.
Fan Error Code Reference
| Code | Fan Location | Common Cause |
|---|---|---|
| 21E/21C | Freezer evaporator fan | Frozen from ice buildup |
| 22E/22C | Refrigerator evaporator fan | Frozen from ice buildup |
| 23E/23C | Condenser fan (back/bottom) | Dust/debris blocking, motor failure |
| ER FF | Freezer fan | Frozen (90% of cases) or motor failed |
Why Fans Freeze
The evaporator fan freezes when:
- Defrost cycle fails — Ice accumulates on evaporator coils and spreads to fan
- Door left open — Humid air enters and freezes on cold surfaces
- Door seal damaged — Warm air continuously leaks in
- Defrost heater failed — Unable to melt ice during defrost cycles
- Defrost sensor/thermostat failed — Defrost cycle doesn’t run properly
Solution 1: Forced Defrost Mode
This is the first fix to try—it works in most cases.
Forced Defrost Procedure
- Press Power Freeze + Lighting simultaneously
- (Some models: Energy Saver + Lighting)
- Hold until display changes (you may hear a beep)
- Press Lighting button repeatedly until “Fd” displays
- Release buttons
- Defrost cycle runs 30-60 minutes automatically
During forced defrost:
- Defrost heaters activate to melt ice
- You may hear water dripping
- Do NOT open doors during cycle
After forced defrost:
- Power cycle the refrigerator (unplug 1 minute, plug back in)
- Listen for fans running
- Error should be cleared if ice was the cause
If forced defrost resolves the error but it returns within a few weeks, there’s an underlying defrost system problem (heater, sensor, or thermostat) that needs to be addressed.
Solution 2: Manual Defrost
If forced defrost mode doesn’t work or isn’t accessible:
- Unplug the refrigerator
- Remove all food — Store in coolers with ice
- Open all doors
- Place towels at base to catch water
- Wait 6-8 hours for complete thaw
- Optional: Use a hair dryer on LOW setting to speed up (carefully, don’t overheat plastic)
- Plug back in and test
Solution 3: Inspect Fan and Motor
If defrosting doesn’t resolve the error, the fan motor may be damaged.
Access the Freezer Fan
- Unplug the refrigerator
- Remove freezer contents
- Locate the back panel inside the freezer (usually held by 2-4 screws)
- Remove the panel to expose the evaporator and fan
Inspection Checklist
- Blade rotation — Spin by hand, should rotate freely
- Ice present — Any ice blocking blade or motor
- Burn marks — Discoloration on motor indicates failure
- Wire connections — Secure and undamaged
- Blade damage — Cracks or chips
Fan Motor Replacement
If the motor is seized, burnt, or won’t spin freely after defrosting:
Common part numbers (verify for your specific model):
- Evaporator fan motor: DA31-00146E, DA31-00146B
- Condenser fan motor: DA31-00070E
Replacement steps:
- Disconnect wire harness from motor
- Remove mounting screws (usually 2-3)
- Transfer blade to new motor if not included
- Install new motor and reconnect
23E/23C — Condenser Fan Error
The condenser fan is located at the back or bottom of the refrigerator, near the compressor.
Troubleshooting 23E
- Unplug the refrigerator
- Pull away from wall to access back
- Locate condenser fan (near compressor, bottom rear)
- Clean debris — Vacuum dust from fan and coils
- Check blade rotation — Should spin freely
- Inspect for obstructions — Remove anything blocking fan
- Check wire connections
Safety note: Condenser area can be hot. Allow refrigerator to sit unplugged for 30 minutes before touching components near compressor.
Symptoms of Fan Errors
21E/22E/ER FF symptoms:
- Warm refrigerator or freezer section
- Clicking sounds from compressor (short cycling)
- Uneven temperatures inside
- Grinding or scraping noise from fan area
- Water leaking (from melted frost)
- Complete silence from fan area
23E symptoms:
- Refrigerator runs constantly
- Compressor area extremely hot
- Poor cooling despite running
- No hot air blowing from back of unit
Model Coverage
This guide applies to Samsung refrigerators displaying fan errors:
- RF series (French Door) — Most common for 21E/22E
- RS series (Side-by-Side)
- RT series (Top Freezer)
- Bespoke models
- Family Hub models
When to Call a Tech
Contact Samsung (1-800-SAMSUNG) or a technician if:
- Fan errors return within 2-4 weeks after defrosting (defrost system needs repair)
- Fan motor is physically damaged or burnt
- Multiple error codes appear simultaneously
- You’re not comfortable removing panels and accessing components
- Condenser coils are severely clogged and need professional cleaning
Typical repair costs:
- Evaporator fan motor replacement: $150-250
- Defrost heater replacement: $150-300
- Defrost thermostat replacement: $100-200
Preventing Future Fan Errors
- Check door seals regularly — Replace if cracked or not sealing
- Don’t overload refrigerator — Blocking vents causes temperature issues
- Keep doors closed — Limit opening time
- Clean condenser coils — Every 6-12 months
- Address defrost issues promptly — Don’t ignore early signs of frost buildup
