E4 – Wine Cooler error code

Uline Wine Cooler error code

E4 is an error code the Wine Cooler uses to flag a condition the owner manual groups with controls, sensors, fans, or door logic. The same characters can mean different branches on different revisions, so the rating plate matters as much as the display.

After storms, wait one clean power cycle, then watch for repeating alarms before assuming the appliance is fine long term.

FAQ

Uline service—answered clearly

Process, pricing, and what to expect during your visit.

EC and ER are general control/communication faults that often indicate a need for diagnostics rather than a fixable user setting. Most wine bottles tolerate brief temperature drift; if the cabinet warms toward 65°F over many hours, move sensitive bottles to the coolest part of your home.

Yes. Dual-zone units have separate thermistors and dampers per zone—mention which zone is acting up so dispatch can plan parts thinking. Single-zone units are simpler but still need accurate model and serial data.

On some Uline series E3 ties to door-position logic. Check whether the gasket seats fully and whether any bottle is pushing the door slightly open. If the code persists after a clean reseat, schedule service.
