Frequently Asked Questions

Sub-Zero Built-In Refrigerator Won’t Turn Off

We recommend considering the main two possible sources of the problem. The first problem can be that the refrigerator simply fails to reach the necessary temperature – either it is a result of a significant drop in efficiency or another kind of malfunction, for example, a Freon leak, lack of maintenance or even air leak from inside the refrigerator. Another common source of this problem among Sub Zero refrigerators is a malfunctioning thermostat. Simply examine the thermostat and check if the temperature is set correctly. We would recommend testing the temperature inside the refrigerator and making sure the temperature is actually below the target. If you determine that the temperature is low enough you might have to carefully examine and possibly replace the thermostat.
Sub-Zero Built-In Refrigerator Makes Loud Noise
It is important to point out that while most of the time the perceived loud noise can be a result of the refrigerator simply taking too long to end the cycle. Sub-Zero built-in refrigerators have additional fans that help to redistribute the cool air within the appliance.
Sub-Zero Wine Cooler Problems
In their essence, Sub-Zero wine coolers employ the same principles of refrigeration as other Sub-Zero appliances. It is the unique internal layout and the particular temperature settings that really matter since even a small temperature deviation can become a problem when it comes to wine storage.

Here are some common problems we see with Sub Zero Wine Coolers:
  1. Wine cooler temperature control issues
  2. Wine cooler won’t turn on
  3. Door won’t close or seal properly
  4. Appliance is running hot
  5. Noisy operation
24 hours
So, what do you do if your wine cooler stops cooling? First, keep in mind that it may take some time for your appliance to reach the required temperature. Wine coolers are oriented for long-term energy-efficient storage and it may take up to 24 hours to reach the target temperature for them after you plug in your new appliance.

Compressor Not Working
If you power on your wine cooler and the controls seem responsive, yet it fails to cool its content efficiently you might have a problem with a malfunctioning compressor. While the sealed system can be difficult to diagnose, a Freon leak is one of the most common problems. We recommend setting up an appointment with us if you believe you have a problem with your compressor or the sealed system.

Is the Door Closed Firmly?

No matter how efficient your wine cooler’s compressor is, it won’t be able to maintain the temperature if there is an air leak. Make sure that the refrigerator door is closing snugly. There should be no cracks or other visible damage on the door seal. We do recommend replacing the seal in case you find out that it’s leaking the cool air since this issue can significantly reduce the efficiency of your appliance.

Clean the Condenser
The condenser is located in the bottom rear side of your appliance. Despite it may be difficult to reach that area, it is strongly recommended dusting the condenser coil every 3 to 6 months.
Sub-Zero refrigerator is leaking water
There are numerous possible causes if your Sub-Zero refrigerator is leaking water. The most common reason for this is a clogged or frozen defrost drain. If it is a frozen or clogged drain, thaw the ice or clear out the drain of debris by flushing it with hot water. Other common culprits of this problem include:
  1. Leaky water tank assembly
  2. Faulty water inlet valve
  3. Misaligned water filter
  4. Cracked water filter housing
Condenser Coil Issues
All refrigeration units have condenser coils, which are typically located either at the back of the unit or across the bottom.

These coils are what your fridge uses to condense and cool its refrigerant. So when the coils become gummed up with dust and dirt, they become unable to release heat efficiently. And in turn, this can cause your fridge to overheat and not cool down properly.
So if you’re experiencing an issue with a Sub-Zero refrigerator that doesn’t seem to be cooling properly, the culprit could quite likely be that you have dirty condenser coils.
To remedy this, start by unplugging your fridge and allowing the coils to cool down. Then, simply use a vacuum to suck up any caked-on dust and dirt, and then give the coils a quick wipe down with a cloth and some warm water.

Once this is done, plug the fridge back in and see if it has resolved your problem.
If not, you might have a problem with your condenser pump or the unit’s internal circulation fan.

So if you still can’t find the source of your problem, give us a call. We’d be happy to stop by and help you diagnose the problem.

Maintenance Plans and Saving

Save money with our maintenance plans and keep your appliances running smoothly!
Preventive maintenance is not about fixing problems with your appliances.

Its focus is on preventing those problems from happening. It includes activities such as adjustments, cleaning, lubrication, repairs, and parts replacement.

Each of these activities is performed by our expert technicians to keep your appliance running in top condition and to prevent breakdowns.

When our technician inspects your unit, he can detect and fix both big and small problems that could eventually lead to expensive repairs if ignored.
What Is Preventive Maintenance?
Annual Maintenance Plans
Why is annual maintenance important? Just as you maintain your car with oil changes and tire rotations, your appliances also need to be cleaned and checked.

For example, dirty refrigerator condenser coils can cause the compressor to overheat. Overheating causes the compressor to stop working, and therefore, the entire refrigeration process stops as well.

There is nothing better for your Sub-Zero appliances than annual maintenance. It ensures your appliances are working at peak efficiency and experiencing considerably fewer breakdowns.
