Preserving Your Sub-Zero Refrigerator and the Food Inside

Keeping the Fridge Running Smoothly

Despite its good looks and cold beverage storage ability, your new refrigerator is a machine that requires some routine maintenance to keep it running smoothly and preserving your Sub-Zero. The food inside also needs to be organized properly to make sure it stays fresh. Let’s take a look at how you can do both without calling for a repair technician.

  • Clean the Condenser Coils

A refrigerator works by drawing heat out of the air that circulates inside the unit. The heat gets captured by the refrigerant that circulates through the condenser coils. The condenser then takes the heated refrigerant to the outside coils, where the heat gets released into the air.

The condenser coils on the exterior of the refrigerator attract dust, hair, and other fine particulates. This accumulation of debris makes it harder for the refrigerant to release the heat efficiently. To compensate for this difficulty, the refrigerator has to work harder to keep the inside cool. In time, this can cause the motor to stop working, requiring an emergency Sub-Zero repair.

Cleaning the condenser coils with a soft-bristle brush every few months will keep the repair tech away.

  • Verify Thermostat Settings

The inside of your refrigerator should be kept between 37 and 40 degrees. This temperature range preserves fresh food without freezing it. Your freezer, on the other hand, should be kept at 0 degrees. This ensures the food inside is kept in a hard freeze for maximum food preservation.

If you set the thermostats too low, the motor will work harder and break down more often, requiring a repair. Use a thermometer to verify the thermostat settings in both the refrigerator and freezer sections.

  • Don’t Keep the Refrigerator Too Full or Too Empty

If you stuff the refrigerator full from top to bottom, the cool air will have difficulty circulating and keeping things cold. Make sure there is space to allow free air flow to minimize wear on the motor.

Conversely, if you take everything out of the fridge, the cool air has nothing to cool, which causes it to continuously circulate. Having a few cold items in the refrigerator helps keep the interior cold without continuously circulating the cold air.

  • Make Sure the Doors Seal Properly

The seals around the refrigerator and freezer doors are what keeps the cold air in. If you feel cold air leaking out when the doors are closed, do a quick check to see if the seals are tight. You may find food or debris build-up is creating the door seal problem. A quick clean-up can fix that problem. However, if you can slip a piece of paper between the seal and door, you need to have a tech fix the seal immediately.

Keeping the Food Fresh

  • Keep beer, soda, and pasteurized juices up top. This area is not the coldest place so sealed and pasteurized containers do best in this location.
  • Put eggs in the middle. Temperature consistency is best in the middle of the fridge. Eggs like this type of environment. Keep them in their original container to prevent smell transference.
  • Keep dairy and raw meat on the bottom. This is the coldest part of the fridge. Milk, yogurt, and other dairy products will last longer here. Raw meat also needs the cold, plus you don’t want the raw meat to drip on other foods below.
  • Place condiments, butter, and soft cheese in the door. The door tends to be the warmest area of the fridge. These items don’t need the coldest temperatures.
  • Use the high humidity drawer for vegetables and berries. Certain fresh foods tend to wilt in the dry air of the refrigerator. The humidity drawer helps keep vegetables and berries from wilting.
  • Keep most fruit in the crisper drawer. This low humidity environment helps keep the fruit from rotting. Don’t wash the fruit before putting it into the drawer as this will only increase the humidity and promote rot.

These tips will help keep your refrigerator running for many years to come while keeping your food as fresh as possible. If you find that your fridge is in need of repair, you can count on the Sub-Zero Experts LA. Contact us today to schedule an appointment with one of our experienced techs.
