A refrigerator is one of the essential kitchen appliances that is a must-have in a household. This is where food, frozen goods, and drinks are stored. This will also help to prevent the premature spoiling of the food. 

Sub-Zero is one of the known and trusted brands when it comes to refrigeration systems. Made from the highest quality materials and modern features and design. But you may be alarmed when all of a sudden that the Sub Zero Fridge Doesn’t Get Cold. There are different reasons why it happens, this includes the components that are not properly clean or need a careful inspection of the unit to determine what is the main cause and do the appropriate repair. 

It can be confusing where to start, but it would be best to start in the most visible parts of the refrigerator that can cause the unit not to get cold.

Door Gasket

The tight seal when the door is closed. It keeps the cold air from coming out and preventing the warm air from coming in. If the gasket is damaged or dirty, this will prevent the door to properly seal when closed. You can clean the dirt of the gasket but if there are tears, cracks, or damages, it should be replaced. Sub-Zero appliance repair can also do the replacement.

Evaporator Coils Frozen

 With the help of the evaporator coils, it transports the refrigerant in a cold and gas form as it travels from the evaporator to the compressor. If the defrost system is faulty, the frost will build up in the coils and will prevent cold airflow. If this happens, it would require a technician to look into it. If there are parts that need to be replaced, we have a one-year warranty on installed parts.

 Problem with the Thermistor

 The thermistor helps to monitor the internal temperature of the refrigerator and communicates its readings to the control board. This regulates the compressor and the evaporator fan. If this is malfunctioning, it may not communicate well to the right temperature and would cause the unit not to be cold enough. Sub-zero refrigerator repair service will check on it further and do the necessary replacement. 

  Faulty Evaporator Fan Motor

 It helps to blow the cool air over the evaporator coils to help the interior of the refrigerator to cool. If there is a problem with the fan, either the refrigerator or the freezer may have an issue due to the increase in the temperature. There are indications that the problem is with the fan motor. If this happens, the fan motor should be replaced. 

 Condenser Coils

 The coils help for cooling the refrigerant which produces the cool air for the refrigerator. If this is covered with dirt and dust, it will not be able to produce ample cool refrigerant that can result in the Sub-Zero refrigerator not being too cool. Keep the coils clean every 3-6 months.

 Other causes can also affect the refrigerator not getting cold. This is are some of the components that Sub-Zero Certified Repair can check and rectify, we can do the following:
