--- title: "Zephyr HI: the Presrv cabinet is above 73°F" description: "What HI means on Zephyr HI: the Presrv cabinet is above 73°Fs, what to check before booking, and when it is not a failure at all." url: "https://winecoolerrepair.center/error-codes/zephyr-hi/" --- # Zephyr HI: the Presrv cabinet is above 73°F Every Presrv manual uses the same limit: once the interior passes 73°F, HI replaces the temperature on the panel, and after an hour at that level the alarm sounds continuously. ## What HI actually means. Every Presrv manual uses the same limit: once the interior passes 73°F, HI replaces the temperature on the panel, and after an hour at that level the alarm sounds continuously. At that point the wine is well above cellar temperature, so the cause needs finding quickly. Zephyr wine cooler display What to do when HI 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 Zephyr Zephyr wine coolers repaired in the kitchen or bar, from a warm zone to a glass door that keeps fogging. ### Source Zephyr Presrv Pro PRPW24C02CG use, care and installation guide Presrv PRW15C01CG, PRW24C02CG, Pro PRPW24C02CG and the full-size PRW24F01CG and PRW24F02CG wine models, all with the same wording. ## Before you book, in this order. Each step comes from Zephyr's own guidance for HI on its wine coolers. Follow it to the end: the last card says whether this is a visit. 01 Push the door shut and run a finger along the gasket for a loose or folded section. 02 Check that the unit is not in Demonstration Mode (a slowly blinking R indicator). 03 Clear anything blocking the front vent and move the cooler away from direct sun or another heat source. 04 If HI stays with the door shut and the vent clear, move the best bottles somewhere cool and book a visit. ### Still there? It usually turns into [wine cooler thermostat and sensor repair](https://winecoolerrepair.center/services/wine-cooler-thermostat-and-sensor-repair/). Book with the code and the model number. ### What not to do HI is not a door alarm; an open door shows a flashing 00 after 3 minutes. It is also not Demonstration Mode, which shows no code at all apart from the blinking R. ## What you may notice with it. The wine cooler problems HI tends to arrive with.

Push the door shut and run a finger along the gasket for a loose or folded section. If it comes back, it needs a visit. ### How long before a Zephyr HI alarm starts sounding? HI appears as soon as the interior passes 73°F, and the continuous alarm follows after one hour. If you hear it, the cabinet has been warm for at least that long. ### Can Demonstration Mode cause HI on my Presrv? It can, because in that mode the compressor and fans never run and the cabinet slowly warms to room temperature. Look for the slowly blinking R indicator before anything else. ### Does the full-size Zephyr column use the same HI limit? Yes. The PRW24F01CG and PRW24F02CG manual gives the same 73°F threshold as the undercounter models. --- **[Read on the site: Zephyr HI: the Presrv cabinet is above 73°F](https://winecoolerrepair.center/error-codes/zephyr-hi/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
