Lights and display work but cooling may be disabled. Start by recording the exact model and what changed. A symptom alone cannot identify a failed part; these checks stay outside the appliance and within normal owner use.
What to check safely
- Confirm the display in the exact model manual
- Use only the manufacturer’s model-specific demo-mode exit steps
- Check actual temperature after cooling resumes
Stop if a step would require removing an electrical cover, bypassing a lock, opening a gas connection, or handling refrigerant. Your exact model manual controls the procedure.
Make the result useful
Record when the problem starts, whether an error message appears, and whether the safe checks changed anything. Compare that with the refrigerator troubleshooting section of your exact owner manual. If the symptom persists or a hazard is present, request qualified service.
For a warm refrigerator, protect food first. An appliance thermometer and the FoodSafety.gov guide are more reliable than the panel setting alone. Food temperature guidance
