sub zero maintenance tips to save your investiment
1. Check the Door Gasket
Just like a regular refrigerator, a sub-zero refrigerator relies on a door gasket to seal the door from the outside air. If the gasket doesn’t get a good seal, it will allow your cool air to escape.
Here’s an easy test you can do on your own using our sub zero maintenance tips:
Close the refrigerator door on a sheet of paper, then try to pull the paper out. If it easily slides out; your gasket might need to be replaced.
2. Keep the Door Closed
One of the easiest things you can do to maintain your sub-zero refrigerator is to keep the door closed whenever possible.
Every time you open the door, warm air enters and cool air escapes. Your refrigerator has to work hard to bring the inside back to its ideal temperature, which puts stress on the motor. The more it has to do this, the more wear and tear the components experience. Your refrigerator might not last as long as you expect, plus it’s using more energy than it needs to unless you deploy Dependable Refrigeration’s sub zero maintenance tips.
3. Clean the Refrigerator Coils
Your refrigerator condenser coils are exposed, which means they’re prone to collecting dust and debris over time. Too much junk can cause your refrigerator to operate less efficiently.
Part of following our sub zero maintenance tips for your sub zero fridge maintenance is to clean your coils to remove any build-up. This helps your fridge avoid overheating while allowing it to run as efficiently as possible.

4. Keep Your Refrigerator Away from Heat Sources
Would you want to put your bowl of ice cream near a warm stove? Or a steak that’s fresh off the grill near an ice-cold pitcher of lemonade? Of course not! Your ice cream would melt and your steak would cool faster.
The same idea holds true for your sub-zero refrigerator. Installing it away from heat sources, such as a radiator or oven, ensures that external temperatures won’t have as much effect on its operation.
Heat influences how often the refrigerator’s compressor will run. When it’s constantly in close proximity to a heat source, it will run continuously and increase the wear and tear on the appliance.
If your sub-zero refrigerator is near a heat source, such as an oven, you might want to explore a different kitchen configuration using our sub zero maintenance tips. This will cut down on your energy usage, plus your refrigerator will last longer.

5. Stock Your Refrigerator and Freezer…
Did you know that it costs more to cool an empty freezer than a full one? That’s because having your refrigerator full of foods and drinks allows it to work more efficiently. It’s easier for your appliance to regulate its internal temperature. Plus, it’s not having to work hard to cool empty space.
Think of all your refrigerated goods as ice cubes in a drink. Ice helps your drink stay cool even when it’s warm outside, at least for a period of time. The goods inside your fridge work in a similar way. It helps the inside of the fridge stay cool even when the door is open and some cool air escapes.
It’s a good idea to try to stock up your fridge once per week instead of making several trips to the grocery store. Why, you ask?
When you make several trips to the store and are constantly stocking the fridge, you’re opening the door more often. Stocking up less often allows you to keep the door closed more, thus ensuring higher operating efficiency. Not to mention, it saves you time and gas when you don’t have to make as many trips to the store.
6. But Don’t Overcrowd It
When stocking your fridge, make sure you don’t overdo it. You will need to leave a little empty space so that air can circulate. Cool air needs to be able to reach all corners and crevices of the appliance. If it can’t circulate air due to overcrowding, it will try to compensate by working harder than it needs to.
This can make your appliance less efficient over time. Plus, it will skyrocket your energy bills when your fridge is constantly running.
So, when you’re filling the fridge, make sure you leave enough room for more. By simply using our sub zero maintenance tips, you will know where the interior air vents are located so you can avoid blocking them.
