Below are some of the most common Sub-Zero refrigerator repair problems we encounter.
There are many potential causes if your Sub-Zero refrigerator is not cooling properly. Here are a few of the most common problems:
Faulty or Obstructed Fan
The fans in your Sub-Zero circulate the cold air and are essential in keeping your entire refrigerator cool. A broken or obstructed fan can lead to warm temperatures in your refrigerator or freezer.
Dirty Condenser Coils
A buildup of dust and debris on the condenser is one of the most common causes of cooling issues. Cleaning Sub-Zero refrigerator condenser coils can help your model cool more efficiently.
Sealed System Issue
A defective compressor, evaporator, or condenser will leave your refrigerator unable to cool properly. These components work together to ensure your refrigerator stays cold.
Damaged Door Seal
A loose, torn, or dirty door seal can leave your refrigerator door unable to seal properly which lets cold air escape. A warm refrigerator may require a door seal replacement.
When you have a Sub-Zero refrigerator dispenser not working as it should, it may be caused by one of these common issues:
Frozen Water Tube
If the water tube that feeds your refrigerator dispenser falls below 0°-10°F, it may freeze. A frozen line will prevent water from reaching the water dispenser or ice maker.
Low Water Pressure
Your Sub-Zero refrigerator requires at least 20 psi of pressure for the dispenser to function. Low water pressure or a faulty inlet valve are the most common causes of this dispenser issue.
Faulty Water Inlet Valve
The water inlet valve in your Sub-Zero refrigerator is what supplies water to the dispenser. If the inlet valve has malfunctioned, the water dispenser will not work properly.
Refrigerator Door Switch
The refrigerator water dispenser is deactivated when the door is open. If the refrigerator door switch has failed, the water dispenser will not work, even when the door is closed.
If your Sub-Zero ice maker isn’t working, one of these common issues may be the cause:
Freezer Temperature
The freezer temperature must remain below 10°F for your refrigerator ice maker to work properly. Check the temperature of your freezer to ensure that it’s cold enough for ice production.
Faulty Water Inlet Valve
If your refrigerator’s water inlet valve has failed, your ice maker won’t get the water it needs to make ice. A defective water valve will require professional service to diagnose and replace.
Ice Maker Assembly
In many cases, a lack of ice production is due to a failure within the ice maker assembly itself. Our Sub-Zero ice maker repair technicians can diagnose and replace the assembly quickly.
Clogged Water Filter
The water your refrigerator uses to make ice first has to pass through the water filter. If the filter is dirty or clogged, it will need to be replaced for your ice maker to function properly again.
Here are a few common reasons the defrost feature on a Sub-Zero refrigerator fails:
Defrost Timer
The defrost timer turns on the defrost heater when necessary to melt frost that builds up on the evaporator coils. If the timer fails, the defrost cycle will not turn on when it’s needed.
Defrost Heater Assembly
The defrost heater assembly is used to melt away frost buildup on the cooling system. If the heater isn’t working as it should, the defrost system will not be able to work properly.
Defrost Thermostat
Your Sub-Zero refrigerator defrost thermostat monitors the evaporator coil temperature and signals the defrost heater to turn on. A thermostat failure may lead to excess frost buildup.
Defrost Control Board
The defrost control board determines how many times the defrost cycle should run. If the control board malfunctions, your refrigerator won’t run the defrost cycle when needed.
If your Sub-Zero Refrigerator is noisy or runs loud, the issue could stem from any of the following causes:
Fan Blade Obstruction
The evaporator and condenser fans can be blocked by debris caught inside. This can lead to loud noises. You can confirm this by turning the fan blades by hand to see if they move freely.
Broken Fan Motor
The condenser and evaporator fan motors are known to generate noticeable noises when they fail. This sound often grows louder when you open the refrigerator door.
Compressor Damage
Your Sub-Zero refrigerator compressor can wear out over time, causing more noise than normal. If your compressor is making abnormal sounds, it may also be a sign that it requires service.
Water Inlet Valve Clog
If you are hearing noises while using the ice maker or water dispenser, the water inlet valve may be restricted by debris. This valve supplies water to the ice maker and dispenser.
If your refrigerator is flashing an error code, it can feel like trying to decipher a different language. Refrigerator fault codes usually mean something specific is wrong with your model. Fortunately, we have the experience and know-how needed to help you decipher what these Sub-Zero error codes are trying to say.
If your refrigerator is flashing any of these codes, it likely means your model will require professional service. Choose Twin Appliances for the fastest, most effective Sub-Zero refrigerator repair Los Angeles and the surrounding areas can offer.
When your Sub-Zero refrigerator is flashing code EC40, it is trying to tell you that your refrigerator is experiencing “Excessive Freezer Compressor Run.” This means that your freezer won’t stop running. If your refrigerator is running at a normal temperature still, this code is most likely caused by dirty condenser coils. If your refrigerator is running at a higher than normal temperature, we recommend you contact us for professional service.
This error code means that there is “excessive refrigerator compressor run.” This means that your refrigerator will not stop running. There are many things that could be causing this. Your compressor is usually affected by the amount of food in your refrigerator, the internal and external temperature, and the amount of time the door is left open. If your refrigerator is flashing this code, give us a call and we can repair the problem quickly.
If your Sub-Zero refrigerator is flashing this code, it could signal a problem with the defrost heater. This means the refrigerator’s defrost system is not generating the heat necessary to function properly. If the refrigerator’s temperature is normal, this could be a faulty error code. Try clearing the code by pressing and holding the Door Ajar Alarm Key for 15 seconds. If the problem continues or the fridge is hotter than normal, we recommend that you give us a call.
This error code is communicating that your Sub-Zero refrigerator is reading thermistor inconsistencies. This could mean that your refrigerator’s evaporator thermistor recorded inconsistent temperatures on multiple occasions. It can also mean that the thermistor has failed. If this error code flashes, we recommend that you contact Twin Appliances for Sub-Zero repair Los Angeles can count on right away.
