UIX is the G5 display communication code. Perlick’s step is to reset power with the rocker switch or the breaker, and to book service if it continues. Perlick freezer display What to do when UIX shows on the freezer ### Kind of code Control board and communication The boards that run the freezer stopped talking to each other, or one of them failed: the main control lost the display panel, or a board reported a problem of its own. A connector loosened by a move and a harness damp from condensation are checked before a board is ordered by model number. Built-in columns and undercounter freezers lean on their electronics more than a basic chest freezer does. ### Usually leads to Freezer control board and alarm repair Repairing the electronic control, display, door switch and sensors that run a modern freezer, including a temperature alarm that sounds without reason or never sounds at all. ### 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).

Follow it to the end: the last card says whether this is a visit. 01 Turn the unit off with the rocker switch or at the breaker, wait a moment, and turn it back on. 02 Check that the display responds and shows a normal temperature. 03 If UIX continues, book a visit and keep a thermometer in the freezer until then. ### Still there?

Turn the unit off with the rocker switch or at the breaker, wait a moment, and turn it back on. If it comes back, it needs a visit. ### Where is the rocker switch on a Perlick G5? It is the unit’s own power switch, described in the G5 manual. Using it or the breaker restarts both the control and the display. ### Will my Perlick freezer keep cooling with UIX? Often yes, since the cooling control is separate from the display. Watch the temperature, because you cannot adjust it until the link is back. ### What causes Perlick UIX besides a bad display? A loose display cable or a brief power problem can also cause it, which is why a power reset comes first. --- **[Read on the site: Perlick UIX: the display lost contact with the control](https://freezerrepair.center/error-codes/perlick-uix/)** **[Book a visit with FreezerRepair.center](https://freezerrepair.center/schedule/)**
