What do Samsung refrigerator error code 116 and 117 mean?
Samsung refrigerator error code 116 and 117 indicate internal communication errors between the main control board, display, or inverter board.
These specific error codes usually appear when internal circuit boards lose their data connection. Because exact error code definitions can sometimes vary depending on the specific model line or manufacturing year, it is always best to double-check your owner’s manual or the manufacturer’s support page.
- Error 116 often relates to a communication breakdown with the inverter control board.
- Error 117 frequently points to display or main board data transmission issues.
- Loose wire harnesses inside the cabinet can interrupt the low-voltage signal.
- Temporary power surges can freeze the digital logic on the control boards.
- Confirm your exact model’s behavior using the official Samsung support page.
What causes Samsung refrigerator error code 116 and 117?
Temporary electrical glitches, unstable wall voltage, or loose internal wiring harnesses commonly trigger these communication error codes.
Modern refrigerators rely on digital microprocessors that are sensitive to power fluctuations. When electrical noise or a momentary brownout occurs, the boards stop communicating properly. Damaged wire connectors due to vibration can also cause permanent signal loss between components.
- Sudden power outages or voltage drops from the main electrical grid.
- A temporary software glitch in the refrigerator main control microprocessor.
- Loose or corroded pin connections on internal data wiring harnesses.
- Internal component failure on either the main board or inverter board.
- Sustained heat or moisture exposure affecting sensitive electronic circuits.
How do I perform a hard reset to clear error code 116 and 117?
Unplug the refrigerator from the wall outlet for five full minutes to reset the control boards.
Before checking internal parts, you must remove power to clear any frozen logic on the digital control boards. Always remember to unplug the appliance or turn off the dedicated circuit breaker before touching internal components or wiring harnesses to prevent electric shock.
- Unplug the refrigerator power cord from the electrical wall outlet completely.
- Wait a minimum of five full minutes to allow all capacitors to discharge.
- Check that the wall outlet delivers steady power by testing with another device.
- Plug the refrigerator power cord firmly back into the grounded wall outlet.
- Observe the control panel to see if error code 116 or 117 returns.
What are the next steps if the reset fails?
Inspect and secure all internal wire harnesses connected to the main control and inverter boards.
If power cycling does not clear error code 116 and 117, you need to verify that all data cables are securely attached. Turn off the circuit breaker before removing any access panels to inspect wiring connections safely. Look for pinched, loose, or corroded wire terminals.
- Turn off the circuit breaker supplying power to the refrigerator.
- Remove the rear access panel to locate the main control board.
- Check every wire harness connector to ensure it is fully snapped into place.
- Look closely for any signs of pinched wires, moisture, or burnt terminals.
- Reattach the access panel securely and restore power at the circuit breaker.
Which fix matches your specific refrigerator symptom?
Match your specific display behavior to the most likely cause and recommended corrective action below.
Different manifestations of communication errors require targeted troubleshooting steps. Review the quick reference table below to identify your specific situation and apply the corresponding repair strategy safely.
| Symptom | Likely cause / fix |
|---|---|
| Error code 116 after power outage | Temporary glitch / Perform 5-minute hard reset |
| Error code 117 on display panel | Display communication error / Check ribbon cable |
| Error returns immediately after reset | Wiring harness loose / Inspect internal connectors |
| Both codes alternating on screen | Control board failure / Professional diagnosis needed |
| Fridge cooling but codes remain | Inverter board issue / Verify service manual specs |
When should you stop and call a technician?
Call a qualified appliance repair technician if wiring checks pass and error codes persist continuously.
Internal board-level diagnostics and component replacements require specialized electrical training and tools. Never attempt to solder or repair circuit boards yourself. If you notice a burning smell, sparking, or damaged wiring insulation, disconnect power immediately and schedule professional service.
- The error codes return immediately after multiple complete power resets.
- Internal inspection reveals burnt spots or component damage on the control board.
- You lack the tools or confidence to safely inspect high-voltage areas.
- The appliance remains under manufacturer warranty and requires certified service.
- Diagnostic testing confirms a failed inverter or main control board.
What information should you have ready before calling for service?
Gather your exact refrigerator model number, serial number, warranty details, and troubleshooting history.
Having accurate information ready speeds up the repair dispatch process and ensures the technician brings the correct replacement parts. You can typically find the model and serial number on a sticker located on the inside wall of the refrigerator compartment.
- Locate the exact model number and serial number on the interior cabinet sticker.
- Note your purchase date to check if the appliance is still under warranty.
- Write down the exact error codes appearing on the display panel (116 and 117).
- List all troubleshooting steps you already tried, such as power resets.
- Note any recent power outages or electrical storms in your area.
How can you keep error codes 116 and 117 from coming back?
Use a heavy-duty surge protector and maintain stable household electrical power to protect sensitive boards.
Protecting your refrigerator from electrical spikes is the best way to prevent future communication errors. Regular cleaning behind the unit also ensures proper ventilation, which prevents overheating of the electronic control boards and extends their operational lifespan.
- Plug the refrigerator into a dedicated, heavy-duty surge protector.
- Avoid using extension cords that can cause voltage drops and power fluctuations.
- Keep the area behind the refrigerator clean to prevent dust buildup on components.
- Ensure proper kitchen ventilation to keep ambient temperatures moderate.
- Schedule periodic electrical system checks if your home experiences frequent surges.
Frequently Asked Questions
Can I keep using my refrigerator if error code 116 or 117 is displayed?
You should check whether the refrigerator is still actively cooling food items. If cooling has stopped, transfer perishable items to a cooler immediately. Running a fridge with active control board faults can sometimes lead to compressor issues, so addressing the error quickly is strongly recommended.
Where is the main control board located on a Samsung refrigerator?
The main control board is typically housed behind a protective metal cover on the lower or upper rear exterior of the refrigerator cabinet. Always disconnect the power cord or turn off the circuit breaker before removing this cover to prevent accidental electrical shock.
What should I do if the error code disappears and comes back a few days later? intermittent codes
n intermittent error code usually points to a loose wire connection, a failing component, or recurring power fluctuations in your home. Check that the power plug fits snugly in the wall and consider plugging the unit into a reliable surge protector to rule out grid voltage spikes.
Are Samsung refrigerator error codes covered under the manufacturer warranty?
Warranty coverage depends entirely on the age of your refrigerator and the original purchase terms. Check your owner’s manual or contact Samsung support directly with your serial number to verify active warranty terms before hiring an independent repair technician.
Do error codes 116 and 117 mean my compressor is broken?
Not necessarily, because these codes specifically indicate communication failures between control boards rather than a direct compressor mechanical failure. However, if the inverter board cannot communicate properly, it may fail to signal the compressor to run, resulting in a warm refrigerator.
Bottom Line
Unplug your Samsung refrigerator for five minutes right now to perform a hard reset and clear temporary communication glitches. If error code 116 or 117 reappears immediately, inspect internal wire harnesses or contact a professional technician.
