True’s own documentation lists Sabbath mode as Star-K certified and kosher compliant, a control-panel setting rather than a problem indicator. True Residential appliance display What to do when Sabbath 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 Confirm with the household whether the setting is wanted before treating it as something to clear. ### Shows up as Appliance Installation Code on a New Unit: Setup Modes and Hookup Messages An appliance installation code is a message a new unit shows because of how it was set up: a demo mode, a water or drain alert, a vent warning or a power check. ### Make True Residential True Residential installs are cold storage only: refrigerator and freezer columns, undercounter units and wine storage for kitchens and outdoor areas. ### Source True Residential service manual, 15″/24″ platform Confirmed in True’s residential service manual for its 15″/24″ undercounter platform, on the same control board that lists Showroom Mode. ## Before you book, in this order. Each step comes from True Residential's own guidance for Sabbath Mode on its appliances. Follow it to the end: the last card says whether this is a visit. 01 Confirm with the household whether the setting is wanted before treating it as something to clear. 02 Use the documented control-panel key combination to toggle Sabbath mode as needed. 03 Verify the cabinet is still cooling normally while the mode is active, since it does not disable refrigeration the way Showroom Mode does. 04 If the control won’t toggle the mode as documented, book a visit rather than keep repeating the key sequence. ### 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 Sabbath Mode is a deliberate, certified household setting, not a stuck control board. A unit that is genuinely not cooling while in this mode is a separate, mechanical problem and not something the mode itself would cause. ## What you may notice with it. The appliance problem Sabbath Mode tends to arrive with. Answer these at the appliance before anyone is booked.

Confirm with the household whether the setting is wanted before treating it as something to clear. If it comes back, it needs a visit. ### What does Sabbath Mode do on a True cold storage unit? It is a Star-K certified, kosher-compliant setting for households observing a religious Sabbath, toggled through the control panel’s key combination — it is not an error and does not need to be cleared unless the household wants it off. ### Does Sabbath Mode stop a True unit from cooling? No — unlike Showroom Mode, Sabbath Mode is meant to keep the unit’s refrigeration running normally while changing how the controls and lighting behave. ### Can I tell Sabbath Mode and Showroom Mode apart on a True control panel? Yes — both appear in the same control-panel key-combination legend but do different things: Showroom Mode deactivates cooling for display, while Sabbath Mode keeps cooling running under a certified observance setting. --- **[Read on the site: True Sabbath Mode: a Star-K certified household setting](https://applianceinstallation.center/error-codes/true-sabbath-mode/)** **[Book a visit with ApplianceInstallation.center](https://applianceinstallation.center/schedule/)**
