The Sub Zero freezers are built tough. They’re designed to stand up to extreme temperatures, heavy use, and even abuse. But sometimes things go wrong. If you’ve got a Sub-Zero fridge or freezer that won’t turn on, it could mean serious trouble.
Here are some common problems and how to fix them.
1. Start Relay
The refrigeration system consists of three parts: the compressor, the condenser coil, and the evaporator coil. When you turn on the power switch, the compressor starts up and begins circulating refrigerant through the coils. This process creates cold air inside the refrigerator compartment.
2. “Run Test”
To make sure the compressor is working correctly, check the temperature gauge. If it reads 0°F, the compressor isn’t operating. You’ll know the compressor is starting because the temperature gauge will rise slowly over several minutes.
3. “Replace Relay”
If the compressor doesn’t start, replace the start relay. There are many types of relays, but most are rated for about 10,000 cycles. If the relay fails after 10,000 cycles, replace it.
4. “Check Condenser Coil”
A burnt smell coming from the condenser coil indicates a problem with the coil itself. To fix the issue, replace the condenser coil.
Evaporator Fan Motor
Check the evaporator fan motor BEFORE you replace it. If the evaporator fan doesn’t work, check the switch before you call an electrician. A faulty evaporator fan causes the freezer to overheat or malfunction.
Condenser Coils
Condensers are located near where cold air enters the freezer. They consist of metal fins that are designed to catch heat from the air inside the freezer and transfer it to the outside environment. These fins are often covered with insulation. When the refrigerator runs continuously, the condenser gets dirty over time. This causes the compressor to work harder to keep the same amount of cool air flowing into the freezer. If you notice your freezer losing too much power, clean the condenser coils.
Condenser Fan Motor
A condenser fan consists of a motor, a bearing, a shaft, and a blade assembly. A motor converts electrical energy into mechanical energy. Bearings support the rotation of the shaft. Shaft supports the rotation of the blades. And blades cool air.
The most common failure mode of a condenser fan is the bearing. To check whether it is worn out, try to spin the blades of the condenser fan with your hand. If the blades stiffly rotate, then you know the bearings are worn out. You can replace the bearings yourself. But do not overdo it. A damaged bearing can cause the entire fan to fail.
You can test the continuity of the motor by connecting a multimeter to one of the wires coming out of the stator. If the voltage reading is 0 V, then the winding wire inside the stator is shorted. This indicates a broken wire or a loose connection. You can repair the problem easily. Just reconnect the wire.
Evaporator Coils
Check the evaporator coil frequently. If it gets too hot, you’ll know because air won’t flow properly. To test it, use an ohm metre. You don’t want to open up the door while testing, though; the fan motor runs off electricity, so opening the door might cause the motor to short out.
If the temperature gauge doesn’t move, check the defrost timer. A faulty timer could prevent the system from automatically defrosting the coils.
Clean the evaporator coils if needed. They’re located inside the refrigerator compartment near the compressor. Use a brush attachment on a vacuum cleaner, or just wipe the coils down with a rag dipped in rubbing alcohol.
Samsung freezer not freezing could mean several problems. First, make sure the power cord isn’t frayed or damaged. Then, check the thermostat and the wiring.
Temperature Control Thermostat
A temperature control thermostat keeps the refrigerator running smoothly. If it stops working, the fan won’t run and the compressor won’t start. Without a temperature control thermostats, you’ll have trouble keeping food cold and the freezer compartment empty.
Subzero Freezer owners need one too. They’re just like regular refrigerators except they use liquid nitrogen instead of electricity to cool down the inside. This type of thermostat controls the flow of liquid nitrogen into the freezer.
What to Do When Your Sub Zero Refrigerator is Not Cold Enough
If you’re looking for a way to make sure your food stays cold longer, there are some things you can do to help. For starters, it’s important to remember that a subzero refrigerator doesn’t actually freeze anything. Instead, it keeps the inside of the refrigerator cool enough to maintain proper humidity levels and prevent bacteria growth.
The best thing you can do is ensure that the temperature settings are correct. First, check to see if the temperature control knob is turned counterclockwise. If it isn’t, turn it clockwise until you find the desired temperature. Next, check to make sure the access panel cover is closed. If it isn’t closed, close it. Finally, turn the power switch off and wait 10 minutes. Once you’ve done those three things, try turning the power switch back on. If the temperature still isn’t working, call a professional.
Check for Sub Zero Error Codes
SubZero refrigerators are built tough. They’re designed to withstand extreme temperatures and harsh conditions. But sometimes problems arise. For example, your fridge might stop working altogether. Or it could start running slowly. In either case, there are several possible causes. You’ll want to check your error codes to see if one of them applies to your situation.
To do that, follow these steps:
• Turn off the power to the unit.
• Remove the door panel cover.
Refrigerator Temperature Is Set Too High
To cool down properly, the refrigerator temperature should be set at around 40 degrees Fahrenheit. If you are living in a cold area like Canada, New England or Alaska, the fridge temperature should ideally be set at 45 degrees Fahrenheit.
The freezer temperature should be set to 0 degrees Fahrenheit. A good rule of thumb is that if it takes longer than one hour to freeze something, it needs to go into the freezer. Adjusting the temperature will take approximately 24 hours. You can check the temperature once every day.
Sub Zero Refrigerator Door Not Closing Properly
A broken door gasket could lead to an increased internal temperature of the refrigerator, which could damage food products stored inside. If you notice that the door won’t close properly, check the gasket regularly to make sure it is intact.
Dirty Sub Zero Refrigerator Coils
A dirty refrigerator coil could lead to problems like:
- – Fridge Compressor Overheating
- – Ice Maker Not Working Properly
- – Freezer Not Functioning Properly
If you notice one of these issues, it might be a good idea to clean the coil.
Here’s how to do it
- 1. Unplug the refrigerator
- 2. Remove the ice maker tray
Refrigerator Fan Motor Failure

Does Your Freezer Need Repairing or Replacing?
A refrigerator or freezer repair should always be done by a professional technician. However, there are many things you can do yourself to save money and avoid unnecessary repairs. If your fridge or freezer needs repairing or replacing, here are some tips to help you decide what to do next.
First, determine if the problem is caused by something wrong with the appliance itself or if it is due to problems with the wiring. For example, if your refrigerator suddenly stops working, check the power cord and make sure it isn’t frayed.
If the issue is related to the wiring, don’t try to fix it yourself. Instead, contact a licensed electrical contractor. They’ll know how to safely troubleshoot the problem and prevent further damage.
Next, determine if the problem requires replacement of the whole unit or just fixing the faulty component. This decision depends on the age of the appliance and the type of problem. For example, if the compressor motor is broken, you might want to buy a new one. On the other hand, if the thermostat is damaged, you could simply replace it. You can find replacement parts online and at home improvement stores.
Finally, keep in mind that refrigerators and freezers tend to break down over time. Sooner or later, you’re likely to experience a breakdown. Before calling a repairman, however, you can perform simple maintenance tasks like cleaning the coils and defrosting the evaporator fan. Doing so helps extend the life of your refrigerator or freezer.
