The LOCK key on the under-counter Wine Reserve blocks every other key when it is held for 3 seconds, and its LED stays lit while the lock is on. It is meant for cleaning the panel or keeping children from changing the settings. Holding LOCK for 3 seconds again releases it. Thermador wine cooler display · also shown as LOCK LED lit What to do when LOCK shows on the wine cooler ### Kind of code Mode, not a failure A setting someone switched on, often by leaning on the touch panel or left over from the showroom floor, rather than a part that wore out: a demo mode that lights the display and the rack lamps while the cooling never starts, a Sabbath setting that turns off the lights and alarms, a child or control lock that ignores every key press, a reminder that the glass door stood open. The cabinet is fine, and its own keys or its manual switch the mode back off. ### Usually leads to No repair Hold LOCK for 3 seconds until its LED goes out. ### Shows up as Wine Cooler Error Code A wine cooler error code appears as letters and digits on the display, a flashing temperature, dashes where a number should be or a blinking symbol, sometimes with an alarm tone and sometimes while the cabinet stays perfectly cool. ### Make Thermador Thermador wine cooler service for cabinets that run cold, run warm or fog up behind the glass. ### Source Thermador Wine Reserve Use & Care Guide, LOCK key Thermador T24UW925, T24UW915 and T24UW905 under-counter Wine Reserve units. ## Before you book, in this order. Each step comes from Thermador's own guidance for LOCK on its wine coolers. Follow it to the end: the last card says whether this is a visit. 01 Hold LOCK for 3 seconds until its LED goes out. 02 Try the temperature keys again; they should respond at once. 03 If the keys stay dead with LOCK off and Sabbath mode off, book a visit for the touch control. ### Cleared? The display has gone quiet and the cabinet is back at its setting without a new part. Should the code reappear this week, or the reds start feeling warm again, book a visit and mention that it came back. ### What not to do A lit LOCK LED is not a failed control board. Keys that ignore you with LOCK dark are a different matter and point to the touch panel or its connection. ## What you may notice with it. The wine cooler problems LOCK tends to arrive with.

Hold LOCK for 3 seconds until its LED goes out. ### Why won't my Thermador wine unit let me change the temperature? If the LOCK LED is lit, the keys are locked. Hold LOCK for 3 seconds to release them. ### Should I use LOCK before cleaning the panel? Yes. It keeps a damp cloth from changing a setting or holding ON/OFF long enough to switch the unit off. ### LOCK is off and the keys still do nothing. What now? Check that SAB is not showing, since Sabbath mode also disables the keys. If neither mode is on, the touch control needs a technician. --- **[Read on the site: Thermador LOCK light on: the Wine Reserve keys are blocked](https://winecoolerrepair.center/error-codes/thermador-lock/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
