Samsung Refrigerator Error Codes — Complete Diagnostic Reference
When your Samsung refrigerator displays an error code, the digital panel is telling you exactly which component or sensor has failed. Unlike older refrigerators that simply stopped working with no explanation, Samsung's control system monitors over a dozen sensors and will alert you to specific failures through alphanumeric codes on the display. This guide covers every Samsung refrigerator error code, what it actually means, and the exact steps to resolve each one.
How Samsung Error Codes Work
Samsung refrigerators continuously monitor their systems through the main PCB (printed circuit board) located behind the rear lower panel. Sensors throughout the unit report temperature, motor status, and system performance back to this board. When a reading falls outside expected parameters, the board posts an error code to the display and may shut down affected systems to prevent damage.
Key Samsung behavior: Some error codes are "latching" — they remain displayed even after the triggering condition clears. A power reset (unplug 60 seconds, replug) clears latched codes. If the code returns after reset, the underlying issue persists.

Samsung Refrigerator Error Code Directory
Temperature Sensor Errors
1E — Freezer Sensor Error The freezer thermistor reports an out-of-range reading (open circuit or shorted). The freezer may run continuously or not at all.
- Location: Clip-mounted sensor on the freezer evaporator housing
- Test: Measure resistance — should read approximately 5kΩ at 77°F (25°C). Infinite resistance = open circuit (broken wire). Zero resistance = short.
- Part: DA32-10109W (most RF/RS models)
- Fix cost: $15-40 parts / $100-200 professional
2E — Refrigerator Sensor Error Same as 1E but for the fridge compartment thermistor.
- Part: DA32-10109W (same sensor, different location)
- Common cause on Samsung: Wire harness damage where it passes through the door hinge area on French Door models. Flexing from door opening eventually breaks the wire.
5E — Fridge Defrost Sensor Error The defrost termination sensor on the fridge evaporator is reading incorrectly. The defrost cycle doesn't know when to stop (or won't start).
- Part: DA32-10105R
- Samsung-specific: On Twin Cooling Plus models, this sensor is on the fridge-side evaporator only. Code 6E covers the freezer-side defrost sensor.
- Impact: Without proper defrost termination, ice builds up on the fridge evaporator (ties into the ice buildup defect)
6E — Freezer Defrost Sensor Error Same as 5E but for the freezer evaporator's defrost sensor.
Fan and Motor Errors
22E / 22C — Fridge Evaporator Fan Error The fridge evaporator fan motor is not spinning or not reaching expected RPM. This is Samsung's most common operational error code.
- Why it's so common: The drain-freeze defect (class-action issue) causes ice to form around the fan blades, physically blocking rotation. The fan motor itself may be fine — ice is the problem.
- First step: Run forced defrost (Lighting + Fridge, hold 8 sec). If fan resumes after defrost, install drain strap kit DA82-02367A.
- If fan still dead after defrost: Motor failure. Replace DA31-00146E.
- Fix cost: $25-65 parts / $150-280 professional
40E — Ice Maker Fan Error The dedicated ice maker compartment fan (on models that have one) is not operating. Ice production stops because cold air can't circulate properly in the ice maker area.
- Part: DA31-00146J
- Check first: Ice blocking fan blades (same drain-freeze defect)
41E — Condenser Fan Error The condenser fan behind the lower rear panel isn't running. Compressor overheats and shuts down.
- Part: DA31-00028E
- Test: With power on and compressor running, the condenser fan should spin. Check for debris blocking blades.
Ice Maker Errors
8E — Ice Maker Motor/Sensor Error The ice maker ejector motor is stalled or the sensor that detects ice bucket fullness is malfunctioning.
- Samsung-specific: Often triggered by ice mass buildup jamming the ejector arm (class-action defect). Forced defrost + drain strap may resolve without replacing the ice maker.
- If motor is actually dead: Replace assembly DA97-07365G
- Fix cost: $80-200 parts / $180-400 professional
14E — Ice Maker Sensor Error The ice maker compartment temperature sensor reports out-of-range values. Ice maker may produce ice at wrong intervals or stop entirely.
- Part: DA32-10109W (mounted inside ice maker housing)
Communication and System Errors
21E — Freezer Fan Communication Error The main PCB cannot communicate with the freezer fan motor controller. Often a wiring issue rather than component failure.
- Check: Wire harness connections at the PCB (rear lower panel) and at the fan motor connector. Corrosion on connectors is common in high-humidity environments.
39E / 39C — Ice Maker Communication Error The main PCB lost communication with the ice maker module.
- Common cause: Wire harness disconnected during a previous repair, or connector corrosion from water exposure (ties to the ice buildup/leak issue dripping on wiring)
84C — Compressor Lock Error The Digital Inverter Compressor is mechanically locked or electrically stalled.
- Samsung-specific: The 10-year compressor warranty covers this. First try: unplug for 5 minutes and retry. If compressor locks repeatedly, it needs replacement under warranty.
- Note: Don't confuse with the overload-protector click (rapid on-off cycling) — that's usually dirty condenser coils overheating the compressor, not a lock condition.
Environmental and Power Errors
PC ER — Power Connection Error Communication failure between the main PCB and the display board. Often triggered by:
- Power surge (very common in Bay Area — PG&E fluctuations)
- Loose ribbon cable between boards
- PCB damage from surge/short
Fix: Check ribbon cable connection. If secure, try power cycling. Persistent PC ER usually means the main PCB needs replacement (DA92-00384B).
OF OF / O FF — Demo/Shop Mode Active Not actually an error — the unit is in retail display mode. Lights and display work but compressor doesn't run (no cooling).
- Fix: Hold Energy Saver + Lighting for 10 seconds (or Fridge + Freezer on some models)
- Why this happens: Power outage resets on some Samsung firmware versions inadvertently activate demo mode

When to Power-Cycle vs. When to Repair
Power cycle (unplug 60 sec) resolves these:
- Transient sensor glitches after power outage
- OF OF / Demo Mode
- Single-occurrence communication errors (21E, 39E)
Power cycle does NOT resolve these (underlying component failure):
- Persistent 22E after defrost (fan motor dead)
- 8E after clearing ice (motor burned out)
- 84C recurring (compressor failure)
- PC ER with visible PCB damage

Samsung Error Codes and the Bay Area Power Issue
Our technicians see a disproportionate number of Samsung refrigerator error codes in the Bay Area due to PG&E power quality issues. Micro-outages (sub-second interruptions) and voltage sags cause:
- OF OF activation — firmware bug resets to demo mode
- PC ER — communication disruption between boards during voltage drop
- Multiple simultaneous codes — the PCB reboots mid-operation and logs phantom sensor errors
Prevention: Install a refrigerator-grade surge protector with line conditioning (not just basic surge strip). UPS backup is even better for Samsung refrigerators with sensitive PCBs. The $40 investment prevents $200+ PCB replacements.
Cost Summary by Error Code Category
| Error Category | Parts Cost | Professional Cost |
|---|---|---|
| Sensor errors (1E, 2E, 5E, 6E, 14E) | $15–40 | $100–200 |
| Fan errors (22E, 40E, 41E) | $25–65 | $150–280 |
| Ice maker errors (8E) | $80–200 | $180–400 |
| PCB/Communication (PC ER, 21E) | $80–200 | $200–400 |
| Compressor (84C) | $200–400 | $400–750 (warranty may cover) |

Frequently Asked Questions
Q: My Samsung refrigerator shows an error code but seems to be working fine — should I worry?
Some Samsung error codes are informational and the system compensates automatically. However, even if cooling seems normal now, a persistent error indicates a degrading component. For example, 22E (fan slow) might not affect cooling today but will progress to complete fan failure. Address error codes proactively.
Q: How do I clear an error code on my Samsung refrigerator?
Unplug for 60 seconds and plug back in. This clears latched codes. If the code returns within 24 hours, the underlying component has failed and needs repair. You cannot permanently dismiss a code without fixing the root cause (the PCB will re-detect the fault).
Q: My Samsung displays multiple error codes — is it totaled?
Not necessarily. Multiple simultaneous codes often result from a single root cause. For example: a drain-freeze event can trigger 22E (fan blocked by ice) + 5E (defrost sensor iced over) + 8E (ice maker jammed). All three resolve with one drain strap kit installation. Before assuming multiple component failures, identify the common root cause.
Q: Does Samsung warranty cover error code repairs?
Samsung's standard warranty is 1 year parts and labor. The Digital Inverter Compressor has a 10-year warranty (parts only, labor is extra after year 1). The ice maker defect may be covered under the class-action settlement regardless of warranty status. Check Samsung.com/support for your specific model's coverage.
