Frequently asked questions
E1 is documented as a temperature-sensor related fault display on some professional units and wine cabinets. The exact probe or circuit varies by model, so the code alone is not a parts order.
No. Wine-cabinet and professional controllers can reuse letter/number pairs differently by series. Match E1 to your model’s documentation before acting.
Note the model and service numbers, photograph the E1 display, and write down whether cooling performance changed when the code appeared.
