Sub Zero Refrigerators are the top of the line kitchen appliance. Aesthetics aside, with the ability to keep your food fresher longer, they are definitely worth the investment.

These refrigerators are often engineered to keep your food fresh with not one, but two compressors that are each specifically designed to cool your fridge and freezer separately. Your Sub Zero fridge is engineered and constructed to keep the air temperature just right to keep your food from drying up and going bad. On the other hand, freezers need to stay dry to minimize freezer burn, and Sub Zero freezers do just that.

These refrigerators are known to last 30 or more years. With each and every appliance you buy, no matter how well you take care of them, you can experience issues if not properly maintained. As time goes on, wear and tear of 24 hours, 7 days a week, 365 days a year for years can impact the life expectancy and repair needs of the refrigerator.

Understanding that these units never get a break or any downtime, as the refrigerator and freezer get older or are used frequently (think of opening of the door) the refrigerator temperature drops 5 degrees every time you open the door. There are 3 common issues we here at Dynamic get called on to repair the most often. Thankfully, each of these issues can be fixed by a knowledgeable, trained repair technician well-versed in Sub Zero repair.

The Vacuum Condenser/Service Light is On

One problem you might encounter is noticing your vacuum condenser light coming on. Your vacuum condenser light points to an issue with your condenser and can be on for various reasons, not just a dirty coil.

If you see your vacuum condenser or service light come on, your condenser coils can often be dirty, which will require it to work harder than it needs to keep cool. One fix for dirty condenser coils is simply cleaning them every six months to prevent dust and dirt build-up. The reason the “ Vacuum Condenser ‘ light comes on is due to the refrigerator running 6 hours or longer nonstop, which can cause many issues and will need to be serviced by a Professional Technician.

Another reason you may see a service light come on is a slow leak in your freon lines. While this issue is not as easy of a fix as the latter, scheduling service with our team at Dynamic to get an expert technician in your area can fix this problem in no time.
