Answer to continue safely
Is it safe to keep using?
Maybe. The fridge will likely continue cooling but may be less efficient. Monitor temperatures and avoid overloading.
Can I reset the code?
Yes. Yes — clean the condenser, reset. If the sensor itself is faulty, the code will return.
When to stop immediately?
Stop if you notice: Temperatures rising steadily, Compressor not running at all.

Power Reset
Leave unplugged for 5 minutes after cleaning, then restart.
The board may recalibrate after a clean reset.

3
Check Airflow
Ensure 5-10 cm clearance behind and above the refrigerator for ventilation.
Restricted airflow causes condenser overheating.

Monitor
Watch temperatures for 4-6 hours after cleaning and reset.
If temperatures normalize, the issue was heat-related.
