Sub-Zero is popular for its highest quality and latest innovations to preserve foods and drinks. Considering its quality components and design, it is less likely that its fridge doesn’t cool properly. From unstable temperature settings to filthy condenser coils, we will get into the main sources why your Sub-Zero refrigerator is acting up.
Sub Zero Refrigerator Not Cold Enough
A defective or damaged part isn’t always the cause once your Sub Zero unit is not cold enough. Regardless of your refrigerator model, a simple adjustment may only be the solution to your problem.
Temperature Too High
When you have a fridge not getting cold, the temperature setting could be adjusted too high. For the standard temperature, its electronic control should be put to 38°F. The freezer needs to be put to 0°F or the ice maker won’t produce ice. In refrigerator units with dial regulators, the freezers and refrigerator dials should be adjusted between 4 and 6. When the appliance temperature needs to be changed, it could last up to 24 hours for it to get to the appropriate temperature.
Door Not Shutting Off Properly
When you leave its door open, the cold air can go out and warm air can get in, decreasing the unit’s internal temperature. Once your Sub-Zero fridge is not cold, see if the door is shut off properly. In most cases, refrigerators make some alarm when the door is still open.
When the door is shut off, inspect its rubber gasket. It makes a strong seal that makes the air cold and blocks the warm air from getting in. When the gasket is filthy or defective, cool air could go out and increase the temperature despite the door being closed. As the dirty gasket can be cleaned using a wet cloth, a defective gasket must be replaced by an expert.
The coils eliminate the heat from the refrigerant in order to produce cool air for the fridge. But if these coils are covered with dirt or dust, they won’t be able to cool refrigerant properly and its temperature can increase. It’s advised that refrigerator coils be cleared twice a year to keep them working efficiently.
Fan Motor Breakdown
The fan that is not running can also be the cause of warmer internal temperatures. A condenser fan spreads the cool air over the condenser coils to help in the cooling of refrigerant. As the evaporator fan helps spread the cool air throughout the whole unit. When either of these fans breaks down, your fridge won’t cool properly.
