T1H is the G5 alarm for high zone 1 temperature. On single-zone units such as the freezer drawers, zone 1 is the cabinet itself; Perlick’s checklist points to the door gasket, a dirty condenser, a blocked front grille, a sudden change in room temperature or warm product recently loaded. Perlick freezer display What to do when T1H shows on the freezer ### Kind of code Temperature and alarms The freezer measured a cabinet warmer than it should be and said so, sometimes with the highest temperature it reached while nobody was looking. The cause can be as simple as a door left ajar or a long power outage, or as serious as a compressor that stopped. Keep the door or the lid shut and check whether the food is still hard before anything else; the alarm is a warning about the food, not a diagnosis. ### Usually leads to Freezer thermostat and temperature control repair Repairing the dial thermostat or the sensor and control that decide when a freezer cools, so it stops running without end or quitting too early. ### Shows up as Freezer Error Code A freezer error code appears on the display: letters and digits, a flashing temperature, or a warning symbol, sometimes with an alarm and sometimes with the freezer still running. ### Make Perlick Perlick freezers repaired in place, whether the trouble is soft food, a stubborn alarm or frost on the walls. ### Source Perlick G5 User Installation & Operation Manual, Form Z3023 (linked from the G5 Luxe 24-inch freezer drawers page) Perlick G5 undercounter models with the touch display, including the G5 Luxe 24-inch freezer drawers (URS24E61). The code appears in Alarm History, which keeps the last ten alarms with date and time. ## Before you book, in this order. Each step comes from Perlick's own guidance for T1H on its freezers. Follow it to the end: the last card says whether this is a visit. 01 Press on the frozen food: move anything that is softening to another freezer or a cooler with ice. 02 Check that both drawers close and seal, that the front grille is clear, and clean the condenser coil if it is dusty. 03 If you just loaded warm product, wait 24 hours and check again; book a visit if T1H returns within a week. ### Still there? It usually turns into [freezer thermostat and temperature control repair](https://freezerrepair.center/services/thermostat-and-temperature-control-repair/). Book with the code and the model number. ### What not to do T1H is not a sensor code; a failed zone probe shows as P1F. It is also not the long door-open alarm, though DO2 can lead to T1H. ## What you may notice with it. The freezer problems T1H tends to arrive with. Answer these at the freezer before anyone is booked.

Press on the frozen food: move anything that is softening to another freezer or a cooler with ice. If it comes back, it needs a visit. ### What is zone 1 on Perlick freezer drawers? On single-zone G5 units, zone 1 is simply the cabinet temperature. Both drawers of the freezer model share it. ### Can an outdoor Perlick freezer show T1H on a hot day? Yes. Perlick names a sudden change in room temperature as a cause. Shade, a clean condenser and a clear grille all help before you call it a repair. ### How long should I wait before booking a visit for Perlick T1H? Perlick’s rule is to book service if the alarm repeats within a week. If food is thawing now, do not wait. --- **[Read on the site: Perlick T1H: the freezer drawers are warmer than their limit](https://freezerrepair.center/error-codes/perlick-t1h/)** **[Book a visit with FreezerRepair.center](https://freezerrepair.center/schedule/)**
