True’s service documentation sets the high-temperature alarm at 50°F for a refrigerator and 70°F for a wine cabinet, sustained for one consecutive hour — a threshold a unit freshly plugged in can still be crossing while it pulls down from room temperature. True Residential appliance display What to do when High Temperature Alarm shows on the appliance ### Kind of code First cool-down A warm alarm in the first day is the most common message a new cold storage unit shows, and the maker's manual usually expects it: from room temperature, a full-size unit can take many hours, and sometimes a full day, to reach its setting. It becomes an installation question when the alarm lasts past that, when the unit was pushed tight against the back wall or into an opening without the air clearances the drawing asks for, or when a door fails to close because the unit tips forward. Leave it closed and empty for the first day and check the gaps against the instructions. ### Usually leads to Built-in and panel-ready fitting Built-in columns, drawers, wall ovens and panel-ready models set to the cutout, anchored, connected, and custom panels hung and aligned. ### 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; the manual also documents a separate door-ajar alarm on the same control board. ## Before you book, in this order. Each step comes from True Residential's own guidance for High Temperature Alarm on its appliances. Follow it to the end: the last card says whether this is a visit. 01 Confirm the unit has had several continuous hours of power for its first pull-down before treating the alarm as a problem. 02 Verify the anti-tip bracket, leveling and door alignment are all correctly set, since a door not sealing flush slows pull-down and can extend the alarm window. 03 Allow the alarm to clear on its own once the cabinet reads back in range. 04 If the cabinet has not reached a normal temperature well beyond a typical pull-down period, book a visit rather than keep resetting the alarm. ### Still there? It usually turns into [built-in and panel-ready fitting](https://applianceinstallation.center/services/built-in-and-panel-ready-fitting/). Book with the code and the model number. ### What not to do This is a temperature-threshold alarm, not proof the compressor has failed — a cabinet that settles into range on its own during first cool-down was simply still pulling down. A unit that stays warm long after a normal pull-down period, especially with the door confirmed sealing correctly, is a different, mechanical problem. ## What you may notice with it.

Confirm the unit has had several continuous hours of power for its first pull-down before treating the alarm as a problem. If it comes back, it needs a visit. ### Is a high-temperature alarm normal on a newly installed True unit? It can be on the first day — a cabinet still pulling down from room temperature can cross the one-hour threshold before it settles into its normal range. ### Could a door installed slightly out of alignment make a True unit’s temperature alarm worse? Yes — True documents leveling and door checks as part of installation, and a door that isn’t sealing flush lets warm air back in, which can extend how long the cabinet stays above the alarm threshold. ### How long should I wait before calling a True unit’s high-temperature alarm a real problem? Give it a full pull-down period of several hours after power-on and confirm the door and leveling are correct; an alarm that persists well beyond that is worth a visit rather than more waiting. --- **[Read on the site: True High Temperature Alarm: a threshold a fresh install can still be crossing](https://applianceinstallation.center/error-codes/true-high-temperature-alarm/)** **[Book a visit with ApplianceInstallation.center](https://applianceinstallation.center/schedule/)**
