6 Sub-Zero Refrigerator Maintenance Tips and Tricks

6 Sub-Zero Refrigerator Maintenance Tips and Tricks

Day in and day out, your Sub-Zero refrigerator works hard to keep your food at the perfect temperature.

Every once in a while, however, your Sub-Zero refrigerators need routine cleanings and maintenance to ensure that your appliance will continue to function for you when you need it most. 

Plus, proper maintenance helps to increase the lifespan of your appliance. 

On the other hand, if you don’t take care of your refrigerator, you shorten its lifespan. And there’s nothing worse than having to purchase a new appliance or pay for those hefty repair bills. 

So to help you figure out what you can do to maximize your appliance’s lifespan, check out these 6 Sub-Zero refrigerator maintenance tips and tricks.

Keep the Door Closed

To keep your Sub-Zero refrigerator running smoothly, make sure to keep the door closed as much as possible. 

This is an important tip because every time you open the door, humid air enters, and cool air escapes. If you continuously go into your refrigerator or leave the door open, the appliance has to work harder to regulate the temperature. 

In turn, this can sometimes lead to parts breaking down sooner than expected.

The appliance also ends up using considerably more electricity to try and keep the temperature regulated. 

So unless you’re going in to grab something, keep that door closed!

Test the Door Gasket

The door gasket on a Sub-Zero refrigerator creates a strong seal to keep cool air in and humid air out. Here’s a great trick to test whether or not your door gasket is working properly. 

Get a slip of paper and close the refrigerator door on the slip of paper. Then try and pull the paper out. 

If the slip slides out easily with very little resistance, you’ll be able to tell that the door gasket isn’t creating a proper seal. On the other hand, if it takes a considerable amount of force to remove the paper, you know that the seal is doing its job!

Clean the Coils

Since refrigerator coils are exposed, over time, it’s common for them to collect dust, dirt, and other household debris. 

One of the easiest and best Sub-Zero refrigerator maintenance tips is to regularly clean the coils and remove any built up dust or dirt. 

Clean condenser coils prevent the refrigerator from overheating. Therefore, cleaning your unit’s coils will help your appliance run more efficiently. 

Dust and dirt act as insulation, which prevents the Sub-Zero refrigerator from properly cooling and can lead to overheating. And both aren’t good for the overall health of the appliance. 

For best results, vacuum your fridge coils every 6 to 12 months. If you have pets that shed, increase the frequency as needed.

Avoid Placing Refrigerator Near Sources of Heat

Here’s a tip about refrigerator placement: don’t ever install your Sub-Zero fridge next to a heat source, such as an oven or radiator. 

The heat will trigger the appliance’s compressor to run more frequently than it should, which puts additional strain, wear, and tear on your appliance’s working components.  

So if you’ve placed your refrigerator next to the oven, for example, you might want to consider re-arranging your kitchen appliances. In this case, the compressor will likely run almost every time the oven is used. 

This isn’t a good idea because the compressor will work overtime. In other words, putting your refrigerator next to a heat source can shorten the compressor’s lifespan, which will end up costing you in the long run.

Fill Your Refrigerator and Freezer

If you’ve invested in a Sub-Zero refrigerator, you truly have got yourself a great appliance! 

However, an empty fridge doesn’t work as efficiently as a full one. 

Having your fridge full of cold food or drink products helps to regulate the unit’s internal temperature. Essentially, cold food products work like ice cubes in a drink, and make it so that your fridge won’t lose all of its cool air every time the door is opened. 

On the same note, if you’re constantly buying food throughout the week, you’ll be opening the refrigerator door more often than necessary to fill it. And once again, decreasing the number of times you open and close the door ensures the appliance works more efficiently. 

So rather than making multiple visits to the grocery store every week, it might be best to only do one large grocery run instead!

Leave Some Space for Air Circulation

While filling your refrigerator and freezer is a great tip to help it maintain its temperature, you also don’t want to overcrowd the appliance. 

Crowding your refrigerator with food and drinks will prevent cool air from circulating the way it should. In turn, this will also lead to your appliance working extra hard to function when it shouldn’t have to. 

So the trick is to fill your Sub-Zero refrigerator with food and drinks, but not to overdo it, and to always leave enough space to allow for adequate air circulation. Also, make sure none of the unit’s interior vents are being blocked by any of your stored products.
