Located in the bustling area of Knightsbridge, our team is dedicated to ensuring your appliance operates flawlessly, so you can focus on what truly matters — enjoying your culinary creations.

Sub Zero is renowned for its exceptional quality and advanced technology in refrigeration. However, even the most sophisticated appliances may encounter issues over time. Whether it's a temperature fluctuation or an unusual noise, recognising the early signs of malfunction can save you both time and money.

Common faults associated with Sub Zero fridge freezers include:

  • Error Code 1: This code indicates a problem with the temperature sensor. It can often lead to inconsistent cooling, which may affect the freshness of your food.
  • Error Code 2: This code suggests an issue with the evaporator fan. A malfunctioning fan can lead to poor air circulation, causing uneven temperatures within your fridge.
  • Error Code 3: This typically indicates a defrost issue. If the defrost cycle isn't functioning correctly, you might notice frost build-up, which can hinder the appliance's performance.

When faced with such issues, it's vital to act swiftly. Our expert technicians at Alpha Appliances are well-versed in the intricacies of Sub Zero products and are ready to assist.
