JennAir describes the Over-Temp Alarm on its column refrigeration as sounding when temperatures remain at unusually high levels, activating after the cabinet has stayed above roughly 48°F (or 15°F in the freezer) for more than 1½ hours — a threshold a freshly installed column can still be crossing during its first pull-down. JennAir appliance display · also shown as Over-Temp Alarm What to do when 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 JennAir JennAir installs are built-in kitchens: panel-ready cold storage columns, wall ovens, ranges, downdraft or hood ventilation and dishwashers. ### Source JennAir support: Temperature Alarm, Column Confirmed on JennAir’s column refrigeration support page; JennAir documents this specifically for its column-style built-in line, distinct from its full-size refrigerator platform’s wording. ## Before you book, in this order. Each step comes from JennAir's own guidance for TEMPERATURE ALARM on its appliances. Follow it to the end: the last card says whether this is a visit. 01 Confirm the column has had several continuous hours of power for its initial pull-down before treating the alarm as a problem. 02 Let the alarm run; it is designed to stop once temperatures return to normal range. 03 Press the Over Temp indicator button to silence and acknowledge the alert once temperatures have normalized. 04 If the column has not reached a normal temperature after a full 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 meant to catch food spoilage risk, not proof the sealed system has failed — a column that settles into range and stops alarming was simply still cooling down. A column that stays warm well past a normal pull-down period is a different, cooling-system issue. ## What you may notice with it. The appliance problems TEMPERATURE ALARM tends to arrive with.

Confirm the column has had several continuous hours of power for its initial pull-down before treating the alarm as a problem. If it comes back, it needs a visit. ### Is it normal for a brand-new JennAir column to sound its Over-Temp Alarm right after installation? It can be. The alarm activates once the column has sat above its threshold temperature for about 90 minutes, which a cabinet still pulling down from room temperature can still be doing on day one. ### How do I stop the Over-Temp Alarm on a JennAir column? Press the Over Temp indicator button to acknowledge it once the column has returned to a normal temperature; the alarm is designed to stop sounding on its own at that point. ### How long should a JennAir column take to cool down after a fresh install? JennAir doesn’t publish a fixed number of hours, but the alarm’s own 90-minute-above-threshold trigger means a column that settles into range within a normal pull-down window shouldn’t keep alarming afterward. --- **[Read on the site: JennAir column Temperature Alarm: a threshold a fresh install can still be crossing](https://applianceinstallation.center/error-codes/jennair-temperature-alarm-column/)** **[Book a visit with ApplianceInstallation.center](https://applianceinstallation.center/schedule/)**
