Sub-Zero's own troubleshooting for a unit that seems to run hot or will not cool lists an active showroom setting alongside a dirty condenser and a door left ajar. A unit delivered from a showroom floor, or one a dealer configured for display, can still carry this setting into a home if nobody turns it off at hookup. Sub-Zero appliance display What to do when Showroom mode shows on the appliance ### Kind of code Setup modes, not failures Nothing is wrong with the new appliance; it has come out of the carton in a state the store or the factory left it in. A showroom or demo mode lights the display and the fans while the unit never cools or heats, a Sabbath setting holds the oven light and hides the controls, a control or shipping lock refuses every key, and some laundry and dish care machines ask for a first calibration cycle before normal use. The manual gives the key sequence that turns each one off; once it is off, the appliance runs as it should. ### Usually leads to No installation Check whether the condenser is clean, since Sub-Zero's own list checks this alongside the showroom setting. ### Shows up as Cold Storage Slow to Cool on the First Day Cold storage slow to cool is a new refrigerator, freezer, wine or beverage unit that still feels warm inside many hours after its installation. ### Make Sub-Zero Sub-Zero installs are cold storage only: built-in and integrated refrigerators, freezers, wine storage and undercounter units, anchored and paneled to the cabinets. ### Source Sub-Zero US undercounter use and care guide Confirmed in Sub-Zero's US undercounter use-and-care guide, which lists this alongside a dirty condenser and an ajar door as causes of excess heat or poor cooling. ## Before you book, in this order. Each step comes from Sub-Zero's own guidance for Showroom mode on its appliances. Follow it to the end: the last card says whether this is a visit. 01 Check whether the condenser is clean, since Sub-Zero's own list checks this alongside the showroom setting. 02 Confirm the door is closing fully and has not been left ajar. 03 Turn off the showroom setting through the appliance's own control panel sequence for the model. 04 If cooling still does not start once the setting is confirmed off, book a visit. ### Cleared? The message has gone from the display, the setting or connection behind it has been corrected, and the new appliance finishes a full first cycle without raising it again. A setup code that comes straight back after the hookup has been checked points to something the install missed, such as a kinked hose or a harness left unplugged, so note it when you book. ### What not to do This is not a compressor or sealed-system failure. Sub-Zero's own list treats a showroom setting as one of the first, most easily ruled-out causes, ahead of anything mechanical. ## What you may notice with it.

Check whether the condenser is clean, since Sub-Zero's own list checks this alongside the showroom setting. If it comes back, it needs a visit. ### The condenser is clean and the door closes fine, but the unit still won't cool. What's next? Sub-Zero's own list moves from those two checks to the showroom setting itself, which has to be turned off through the control panel rather than fixed by cleaning or adjusting the door. ### Is showroom mode the same as the unit being unplugged? No — Sub-Zero documents them as separate causes on the same troubleshooting list; a unit in showroom mode still has power and a working display, just no active cooling. ### Could a dealer have left showroom mode on by mistake before delivery? It's a common enough oversight that Sub-Zero's own manual lists it as one of the first things to check on a unit that runs hot or won't cool, right alongside a dirty condenser. --- **[Read on the site: Sub-Zero's showroom setting on a cold storage unit](https://applianceinstallation.center/error-codes/sub-zero-showroom-mode/)** **[Book a visit with ApplianceInstallation.center](https://applianceinstallation.center/schedule/)**
