A blinking temperature on your Samsung refrigerator means the internal temperature has risen above 59°F (15°C), usually from a door left open or power outage. Close all doors and wait—blinking stops automatically once the fridge cools down. All icons flashing after power restoration is normal self-diagnostic behavior.
| Error Code | Blinking Temp / 83E / 85E / 86E |
|---|---|
| Meaning | High temperature alert or compressor voltage issue |
| Difficulty | Easy |
| Time to Fix | 5-10 minutes (plus cooling time) |
| Tools Needed | None required |
| DIY Fixable | Yes |

A blinking or flashing temperature display on Samsung refrigerators is designed to get your attention when something needs addressing. In most cases, it indicates the temperature is too high and the refrigerator needs time to cool down.
Why Temperature Display Blinks
According to Samsung: “A blinking temperature display is trying to get your attention, typically because the temperature is too high and things need to cool down. It could also be because a door has been left open.”
Triggers for blinking:
- Internal temperature rose above 59°F (15°C)
- Door left open allowing warm air in
- Power recently restored after outage
- Large amount of warm food added
- Ambient temperature extremely high
All Icons Flashing After Power Outage
This is normal. According to Samsung: “When all of the icons on the display are flashing after being plugged in, or after a power outage, this is normal. The fridge is running a self diagnostic.”
What to do: Wait 1-5 minutes for the self-diagnostic to complete. No action required unless flashing continues beyond 10 minutes.
How to Stop Temperature Blinking
Step 1: Check All Doors
- Verify all doors are fully closed
- Check door seals for obstructions (food containers, drawers not aligned)
- Look for ice buildup on gaskets preventing seal
- Ensure nothing inside is pushing against the door
Step 2: Wait for Cooling
Once doors are properly closed:
- Blinking stops automatically when temperature drops below 59°F (15°C)
- This may take several hours after a power outage or door left open
- Keep doors closed as much as possible during recovery
Step 3: Force Stop (If Needed)
If blinking persists even though the interior feels cold:
Button reset:
- Press Power Cool + Power Freeze simultaneously for 5 seconds
Power cycle:
- Unplug for 5 minutes, then restore power
Normal Stabilization Times
After a power outage or when first installed:
| What | Time to Stabilize |
|---|---|
| Control panel temperature display | Up to 4 hours |
| Interior reaching target temp | Up to 28 hours |
| Ice maker resuming production | Up to 24 hours |
Resist the urge to frequently open doors to check if the refrigerator is cooling. Each door opening lets warm air in and delays temperature stabilization.
Compressor Voltage Error Codes
If your display shows a specific error code along with or instead of blinking temperature:
83E/83C — Compressor Abnormal Current
What it means: The inverter board detected abnormal electrical current to the compressor, usually from a power surge or outage.
Fix: Unplug for 60 seconds to 5 minutes, then restore power. Monitor for 24 hours.
When to call tech: Error returns after reset, or compressor doesn’t start.
85E/85C — Compressor Under Voltage
What it means: Voltage dropped below normal operating range (brownout condition).
Fix:
- Family Hub: Press OK button for 3 seconds
- Other models: Unplug 60 seconds, restore power
Prevention: Ensure refrigerator is on a dedicated circuit, not shared with high-draw appliances.
86E/86C — Compressor Over Voltage
What it means: Higher than normal voltage detected, typically from a power surge or lightning strike.
Fix: Unplug 60 seconds to 5 minutes, restore power.
Prevention: Install a surge protector to protect against future voltage spikes.
When Temperature Won’t Stabilize
If temperature display keeps blinking after 24+ hours with doors closed:
Check for:
- Demo mode (OF OF) — Cooling is disabled. Exit demo mode →
- Condenser coils dirty — Clean with vacuum or brush
- Clearance issues — Ensure 2+ inches on sides and back
- Fan errors — Listen for fan noise; 21E/22E indicates fan problem
- Defrost issues — Frost buildup blocking airflow
Food Safety After High Temperature
If your refrigerator was warm (above 40°F) for an extended period:
| Situation | Food Safety |
|---|---|
| Above 40°F for less than 2 hours | Food is safe |
| Above 40°F for 2-4 hours | Use perishables immediately |
| Above 40°F for more than 4 hours | Discard perishables |
Perishables to discard: Raw/cooked meat, poultry, fish, dairy, eggs, soft cheese, leftovers.
When in doubt, throw it out.
