PHF is the G5 humidity sensor alarm. Perlick installs a humidity sensor on its wine reserves and lets you set a humidity percentage on them, so this code belongs to wine units. With the sensor out, the reserve cannot manage humidity as set. Perlick wine cooler display What to do when PHF shows on the wine cooler ### Kind of code Temperature sensors The control has lost a believable reading from one of its thermistors: the probe in a zone, the one on the cold plate or coil, or on some models the one watching the room. With no trustworthy number, the cabinet either chills the bottles far below cellar temperature or lets a zone drift warm. A sensor sitting in frost, pinched behind a rack or unplugged during a move is ruled out before a new one is ordered. ### 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).

Acknowledge the alarm on the display. If it comes back, it needs a visit. ### Why does humidity matter in a Perlick wine reserve? Air that is too dry can dry corks over years of storage, and air that is too damp encourages mold on labels. That is why Perlick lets you set humidity on its wine units. ### Can I keep storing wine with PHF showing? Yes, short term. Temperature matters more than humidity over weeks, so PHF is not urgent. ### Where can I see the humidity reading? In the diagnostic window of the service menu. With PHF active, that reading cannot be trusted. --- **[Read on the site: Perlick PHF: the wine reserve humidity sensor has failed](https://winecoolerrepair.center/error-codes/perlick-phf/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
