4 Easy Steps

As easy as it is to clean Sub-Zero refrigerator coils, this simple job utilizes specific steps and equipment. The following step-by-step guide details what you’ll need and how to perform each task. But, first, here’s why regular condenser coil cleanings are so vital to your fridge’s function.

Why it’s Important to Clean Sub-Zero Refrigerator Coils

Refrigerators create cool air via a condenser that removes heat from refrigerant as it flows through coils. With time, these coils can become coated in dust and debris, making it harder for the refrigerant to dissipate heat. This makes the condenser work harder to keep the refrigerator cool. Over time, an overworked compressor can result in inconsistent cooling, breakdowns and costly repairs.

Sub-Zero maintenance tips include regular condenser coil cleanings every 6-12 months. You may need to clean them more frequently if you have pets in your home or if  “Vacuum Condenser” flashes on the control panel. Here’s how to clean Sub-Zero condenser coils quickly and easily.

Step 1: Turn off Power to the Refrigerator

To maintain your safety, the first step in how to clean Sub-Zero refrigerator coils is to turn off power to the unit. On most models, the power can be turned off by pressing the POWER button on the control panel. Other Sub-Zero refrigerators have a control knob that can be turned to 0 or OFF to eliminate power.

Step 2: Remove Sub-Zero Refrigerator Grille

Sub-Zero refrigerator coils are behind a grille that must be removed to access them for cleaning. On Designer (formerly Integrated) models, the grille is at the bottom of the refrigerator and must be unscrewed to remove. For Pro Series and Classic (formerly Built-In) models, the grille is at the top of the unit. Grasp the grille at the bottom to pull it out and upward.

Step 3: Brush and Vacuum Away Debris

Use an appliance brush to gently remove any visible dust and dirt from in and around the coils. Clean refrigerator coils with a vacuum hose and brush attachment to remove any lingering debris. Move the brush in a vertical, up and down motion to avoid harming the condenser fins. Lastly, vacuum the area around the condenser, as well as the surrounding floor space, if necessary.

Step 4: Replace the Grille and Restore Power

The final step in how to clean Sub-Zero refrigerator coils is to replace the grille. For grilles at the bottom of the refrigerator, replace the screws and tighten them to secure the grille in place. Grilles on top of the refrigerator can be replaced by tilting it downward before pushing it into place. Once the grille is repositioned, restore power to the unit via the control panel or knob.

If the refrigerator had cooling issues due to dirty condenser coils, it may take up to 24 hours to regain its proper temperature.
