How to Clean Sub-Zero Refrigerator Coils in 3 Steps



As high-functioning as Sub-Zero refrigerators can be, they still require consistent maintenance to operate to their fullest potential. Regular cleanings of the condenser coils can foster the best performance, but how do you clean Sub-Zero refrigerator coils properly? An appliance brush and vacuum hose attachment can do the job safely and easily. Learn why this maintenance is so important, as well as the right steps to take.

Clean Sub-Zero Refrigerator Coils With This Step-by-Step Guide

Cleaning refrigerator coils doesn’t always require a lot of time or tools. Rather, some simple home equipment and the right methods can clean Sub-Zero refrigerator coils in under an hour. Our step-by-step guide takes you through the simple process but, first, here’s why coil cleanings are so important.

Why You Need to Clean Sub-Zero Refrigerator Coils

Cleaning the condenser coils is a small task that can have big repercussions. These coils remove heat from the refrigerant, enabling the refrigerator to maintain its cool temperature. If the coils get coated in dust and dirt, it’s harder for them to do their job. This makes the condenser work harder to maintain the refrigerator’s temperatures, risking breakdowns of multiple components and costly repairs.

Most refrigerator maintenance tips suggest cleaning the coils at least once a year. If you have pets in the house or the control panel displays the “Vacuum Condenser” message, you should clean them more frequently. The guide below details how to clean Sub-Zero condenser coils in 3 simple steps.

Step 1 – Remove Sub-Zero Refrigerator Grille

Before removing the grille, turn off the refrigerator’s power at the control panel. Sub-Zero also recommends wearing work gloves to avoid injury.

The grille is located either at the top of the unit (in Classic and PRO models) or at the bottom (in some 500 and 600 series models). Grilles for the Classic and PRO models can be pulled forward and swung up by hand. Some grilles on the 500 and 600 series models must be unscrewed to access the condenser coils. Others have springs as well as screws that release. Refer to your user manual to determine how to remove the grille on your model refrigerator.

Step 2 – Clean with Vacuum Hose Attachment

Clean refrigerator coils with a vacuum’s hose attachment and soft bristle brush. To avoid damaging the condenser fins, move the hose up and down in a vertical motion to remove dust and debris. Vacuum up any particles around the coils or use an appliance brush to access hard-to-reach areas.

Step 3 – Replace the Grille

After you clean Sub-Zero refrigerator coils, replace the grille back to its original position. On Classic and PRO models, the grille can be pulled down and pushed back in place. Some 500 and 600 series models require that screws and/or springs be replaced or reconnected. Once the grille is replaced, restore power at the control panel.
