No verified model list is available for this code
A manufacturer code/support source may be available, but no exact supported model has been documented for this record. Do not treat the code as a model-specific diagnosis without checking the manual.
Verify the full model number against the manufacturer manual.
Open manufacturer sourceWhat does this display message mean?
DE ON indicates showroom/demo mode; normal cooling may be disabled.
Manufacturer guidance is model/type dependent. The code alone does not identify a failed part.
The exact code and primary meaning appear in manufacturer documentation. Scope: Üreticinin belirttiği cihaz türü / desteklediği model ailesi. Individual parts and all models are not verified.
Open manufacturer sourceWhat can you try?
- 01
Record the code and exact appliance model
Photograph DE ON as displayed and record the full model number from its label. Samsung may use different meanings for the same characters on other products.
What the result means: Do not treat a generic code as proof of a failed component.
- 02
Check showroom mode and food safety
DE ON can disable normal cooling although the display is powered. Move perishable foods to safe refrigeration if necessary.
What the result means: Demo mode does not prove a compressor fault.
- 03
Exit demo mode using your exact panel instructions
Samsung Türkiye describes holding Mode and Child Lock for more than five seconds on the illustrated panel. For different layouts consult that model manual instead.
What the result means: A brief DE/OFF display may confirm the mode change.
- 04
If DE ON remains, follow manufacturer support
The referenced Samsung guidance allows a 30-second power disconnect for that mode. Never handle a wet, hot, damaged or unsafe connection.
What the result means: Request support if normal cooling does not resume.
- 05
Escalate with useful details
Give support the exact DE ON display, full model, when it appeared and safe checks completed. Do not run the unit with smoke, leakage, burning smell or breaker trips.
What the result means: A service technician must test the suspected component rather than guessing from the code.
Stop immediately for leaks, smoke, burning smell or electrical danger. For gas leaks, leave the area and call local emergency services.
How do you actually fix this?
Start with safe checks. Some codes have no safe home fix; in that case we explain what the professional repair actually involves.
Practical fixes you can try
- Showroom mode may disable cooling; follow the model-specific Demo/Shop Mode exit instructions, never random button combinations.
- Use your exact manual to distinguish a fault from an operating mode or maintenance reminder.
- For fan-speed, auto-clean, test or showroom indicators, return to a normal mode using the controls in the manual. No part replacement is implied.
If it persists, how is it actually repaired?
An informational indication usually needs no repair. If it remains after the specified maintenance, a technician verifies the counter or detection logic before considering any part repair.
How do you know it is fixed? The indicator should clear on returning to normal mode or after the manufacturer-prescribed maintenance reset.
Safety and warranty: Warranty terms depend on manufacturer, model and local law. Damage caused by unauthorised disassembly or improper repair may be excluded. Live electrical work, gas, refrigerant circuits and sealed cabinets require qualified professionals; this is not a DIY instruction for those tasks.
Evidence: The manufacturer link above supports the broad code meaning. The repair pathway is a general technical diagnostic explanation, not a confirmed failed-part diagnosis for every model.
