T1L and T2L are the G5 low temperature alarms. Perlick’s checklist starts with the door and gasket and with sudden changes in room temperature, which on an outdoor or garage install can pull a zone down on a cold night. Perlick wine cooler display · also shown as T2L What to do when T1L shows on the wine cooler ### Kind of code Temperature and alarms The cooler read a zone well away from its setting and raised an alarm, sometimes showing the warmest figure it reached while the house was empty. The reason may be as small as a door left resting on a bottle neck or a long outage, or as serious as cooling that has stopped. Keep the glass door shut and feel a bottle in the middle of the rack before doing anything else; the alarm is a warning about the wine, not a diagnosis. ### Usually leads to Wine cooler thermostat and sensor repair Testing and replacing the thermostat or the temperature sensors that tell a wine cooler when to cool, when the cabinet runs too cold, too warm or back and forth. ### 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 Perlick Perlick wine cooler repair for units under the counter or behind the bar that no longer keep a steady temperature. ### Source Perlick G5 User Installation & Operation Manual, Form Z3023 (linked from the G5 Luxe 24-inch wine reserve page) Perlick G5 Core and G5 Luxe wine reserves with the touch display, single-zone (URS15W, URS24W) and dual-zone (URS24D).

Follow it to the end: the last card says whether this is a visit. 01 Check the zone settings and confirm nobody lowered them. 02 Think about the room: a cold snap near an outdoor or garage unit can cause this. 03 If the alarm returns within a week, book a visit. ### Still there?

Check the zone settings and confirm nobody lowered them. If it comes back, it needs a visit. ### Can a cold garage set off T1L on a Perlick? Yes. Perlick names sudden room temperature changes as a cause, and its wine units have a lower room limit of 42°F or 5°F below the set point. ### Is T1L harmful to wine? Mild cold slows aging. Near-freezing temperatures can push corks, so move bottles if the zone keeps dropping. ### Why does a door problem cause a low alarm? A door that does not seal lets in air and moisture that can confuse the cooling cycle. Perlick lists it first for both high and low alarms. --- **[Read on the site: Perlick T1L: a wine zone has dropped below its low limit](https://winecoolerrepair.center/error-codes/perlick-t1l/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
