Safety notice
Safety: Do not attempt live electrical testing, bypass safety switches, or open sealed refrigeration systems. If you are unsure, call a professional.
Safe homeowner checks
- Power cycle the appliance (turn off/unplug for 60 seconds, then restart).
- Confirm the breaker is fully on (some appliances use two linked breakers).
- Check for obvious blockages (filters, drain hose kinks, lint buildup) where applicable.
- If the code returns, take a photo of the display and note when it appears (start, mid-cycle, heating, draining) — it helps diagnose fridge issues faster.
Stop DIY and call a technician if…
- You smell burning, see smoke, or notice sparking.
- There is active leaking or water near electrical components.
- The appliance is overheating or repeatedly trips the breaker.
- The error code returns immediately after basic checks or the unit will not run safely.
Error Codes by Brand
Samsung Refrigerator Error Codes
Samsung appliance repair in Ottawa
| Error Code | What It Usually Means | Safe Homeowner Check | When to Call Fixer |
|---|---|---|---|
| 21E / 22E | An evaporator or condenser fan is not running at the speed the control expects, which can reduce cooling performance. | Listen for fan noise at the back or inside the fridge. Confirm vents inside the cabinet are not blocked by food. Power off for two minutes, then restore power once. | If cooling is weak and the code returns, Fixer can test fan motors, wiring, and control-board output. Fixer does not perform sealed-system refrigerant repairs. |
| 40E | A fan or airflow feedback fault was detected in the fresh-food or freezer compartment air path. | Check that interior vents are clear and the doors close fully on both sections. Avoid packing items against the rear wall where fans need airflow. | Fixer can diagnose fan circuits, defrost-related airflow issues, and control signals. Sealed-system compressor or refrigerant work is outside our scope. |
| 23E / 24E / 25E / 26E | A fan, defrost, or cooling-area feedback fault was detected. The exact zone varies by model and may affect fresh-food or freezer airflow. | Make sure both doors close fully, interior vents are not blocked by food, and heavy frost is not building up on the rear wall. | Fixer can diagnose evaporator and condenser fans, defrost parts, sensors, wiring, and control-board output. If diagnosis points to sealed-system refrigerant repair, Fixer will explain the finding but does not perform sealed-system refrigerant repairs. |
| 41 / 39E | Communication between control boards or the display panel is interrupted, which can affect temperature readouts and cooling commands. | Power off for two minutes at the breaker or unplug, then restore once. Note whether the display is blank, frozen, or showing conflicting temperatures. | A proper diagnosis can confirm whether the issue is wiring, a display board, or a main control board before expensive parts are ordered. |
| 84C / 85C | The refrigerator detected a voltage or power-quality issue that may affect compressor and fan operation. | Confirm the fridge plug is fully seated and the outlet is not shared with high-draw appliances on the same circuit. Avoid extension cords. | If 84C or 85C returns on a stable outlet, Fixer can test supply voltage, wiring, and control-board power input. We diagnose electrical faults — not sealed-system refrigerant repairs. |
| OF / Cooling Off | Cooling Off or demo mode is active, so the fridge may not cool even though it appears powered on. | Check your manual for how to exit Cooling Off or demo mode — often a combination of panel buttons. Confirm children have not activated a lock or display setting. | If the fridge will not exit Cooling Off after following the manual steps, Fixer can verify control-panel and board settings before assuming a cooling-system failure. |
| 5E / rF | A defrost sensor, defrost circuit, or fan feedback fault was detected. Frost buildup can follow if defrost does not complete. | Check for heavy frost on the rear wall of the freezer. Avoid chipping ice with tools. Keep doors closed as much as possible until service is booked. | Fixer can test defrost heaters, sensors, wiring, and fan circuits electrically. We do not perform sealed-system refrigerant or compressor repairs. |

| Er IF | The ice maker fan or ice compartment fan may not be running correctly, reducing cooling in the ice zone or freezer section. | Confirm the ice maker is not jammed with frost and that freezer drawers are not blocking vents. Allow the door to stay closed for several hours after a reset. | If ice production or freezer cooling stays weak, Fixer can test the fan motor, wiring, and control-board signal. |
| Er FF | The freezer fan may not be running correctly, or frost buildup may be blocking air movement through the freezer section. | Make sure the freezer door closes fully and food is not blocking air vents. Avoid leaving the door open during loading. | If cooling is weak or the code returns, Fixer can test the fan motor, sensor, wiring, defrost system, and control-board signal. If the issue points to sealed-system refrigerant repair, Fixer will explain the finding but does not perform sealed-system refrigerant repairs. |
| Er CF | The condenser fan may not be running as expected. Poor heat rejection can affect overall cooling performance. | Pull the fridge slightly forward if safe and confirm nothing is blocking the rear vent area. Clean visible dust from the condenser area only if you can do so without disassembling panels. | If the code returns, Fixer can test the condenser fan motor, wiring, and control output. Sealed-system refrigerant work is not performed by Fixer. |
| Er dH / F dH | A defrost system fault or extended defrost condition was detected. Frost may build up behind the evaporator cover on some models. | Keep the doors closed and avoid manual chipping at ice inside the freezer. Note whether fresh frost returns quickly after a power cycle. | Fixer can test defrost heaters, sensors, fuses, and control-board defrost logic. If cooling loss suggests sealed-system failure, we will explain options without performing refrigerant repairs. |
| Er FS / Er rS | A freezer or refrigerator temperature sensor reading is out of expected range, so the control may not regulate cooling correctly. | Confirm vents are clear and doors seal properly. Avoid stuffing warm food in large batches while troubleshooting. | Sensor and wiring faults need meter testing. Fixer can confirm whether the sensor, harness, or control board is at fault. |
| Er CO | A communication fault between control boards or modules was detected. Cooling behavior may be unpredictable. | Power off for two minutes, then restore power once.
