What Demo Mode Means
Not a failure, but it looks like one. Thermador's French-door guide states that "the appliance does not cool in demo mode", and its troubleshooting table gives "Showroom mode is switched on" for a unit that is not cooling while the displays and lights work.
Common Causes of Demo Mode
- Demo mode left on from a showroom or delivery check
- Demo mode switched on by accident while browsing service settings
🔧 One Safe Check You Can Try
Swipe to "Service", touch "Advanced Service", then "Demo Mode" and switch it off. The guide notes the setting is only offered for a certain time after the appliance is started.
⚠ Why You Shouldn't Go Further Than That
- If the option is gone and the unit still is not cooling with lights and display working, the problem is real and needs diagnosis.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
