How to Clean Coils on Sub Zero Refrigerator Models

Sub Zero makes some of the best home refrigeration appliances in the world. Unfortunately, even the best refrigerators can develop cooling issues if you fail to keep up with maintenance. The good news is you’ve come to the right place for Sub Zero refrigerator troubleshooting tips! We’ll help you avoid major repairs by showing you how to clean coils on Sub Zero refrigerator models.

Steps for How to Clean Coils on Sub Zero Refrigerator Models

All refrigerators use condenser coils as part of the cooling system. They’re used to remove heat from the interior, resulting in the cold temperatures that keep your food fresh. The problem is that these coils inevitably become covered in dirt and dust over time.

As debris accumulates on the coils, cooling efficiency is reduced and your refrigerator has to work harder to stay cold inside. If you don’t clean Sub-Zero refrigerator coils on a regular basis, your model can suffer a serious breakdown. Luckily, when it comes to Sub Zero refrigerator maintenance, cleaning refrigerator coils is quick and easy!

How Often to Clean Refrigerator Coils?

It’s recommended that you clean coils on Sub Zero refrigerator models at least once every 6 – 12 months. If you’re a pet owner, be sure to clean them more frequently as pet hair can contribute to the problem.

Luckily, the cleaning process is quick and easy! All you’ll need is an appliance brush, gloves, and a vacuum cleaner with a hose attachment. Here’s how it’s done…

Step 1 – Remove Sub Zero Refrigerator Grille

Before you begin cleaning, be sure to power down the unit. Once the refrigerator is off, you’ll need to locate the grille that covers the condenser coil compartment. Most Sub Zero models have the grille at the top of the unit, but others can be found near the bottom. Reference your model’s use and care guide if you’re unsure of where to look.

Some grilles can be lifted straight up to access the coils, while others need to be unscrewed. If this is the case for your model, open the refrigerator doors and unscrew the grille cover. Now you can carefully tilt the top toward you, unhook the connecting springs, and lift to grille to remove it.

Step 2 – Clean the Condenser Coils

Now that you have access to the condenser, we’ll show you how to clean Sub Zero refrigerator coils properly. Start by using your appliance brush to wipe away any dust or debris on the coils. Try to be as gentle as you can while also removing all of the built-up dirt. It’s also important not to disconnect or damage any other components during this step.

After all of the debris has been brushed off, use your vacuum hose attachment to clean up any loose dirt on the coils or within the condenser compartment. Once everything looks brand new again, the job is done! Now you can take the final step to wrap things up.

Step 3 – Replace Sub Zero Refrigerator Grille

Follow the same process as Step 1 in reverse to reinstall the grille. If your model required you to unscrew the grille, slot it back into position and make sure to reattach the springs. Now you can replace the screws that hold it in place and test the refrigerator.

Turn the power back on and let your model run for at least 24 hours before checking the temperature. If everything looks good the next day, you’ve successfully learned how to clean Sub Zero condenser coils!
