1. Home » Avoid Sub-Zero Refrigerator Issues with These Easy Maintenance Tips
Sub Zero refrigerators are made to perfection, with each unit undergoing various tests before being
released. Sub Zero has been a household name for decades, and the brand has been unstoppable.
Creating refrigeration masterpieces is what they are known for, and people flock to their stores to get
the latest release. With high expectations of the products, Sub Zero users think that their units won’t
need to be regularly checked. But, every appliance needs maintenance to avoid malfunctions that
could lead to bigger issues.
We gathered six (6) Sub Zero clean and care tips that you can do at home without professional
help.

2. 1. Always close your refrigerator door.
Practice always closing the door of your
refrigerator. Sometimes, a small nudge
won’t be enough, so it’s better to push it
until you feel it sticks to the refrigerator. This
way, no cold air seeps out, and food is well-
preserved.
Not pushing your door all the way can lead
to damages, for your unit will work extra
hard to reach its desired temperature. You
will need a Sub Zero refrigerator
appliance repair if not handled properly.
2. Schedule routine checkups for your
gasket doors.
Door gaskets are essential parts of your
refrigerator. If they malfunction, there is a
high chance that your door won’t properly
close, and your food and drinks will quickly
go bad. At the slightest malfunction, get your door gasket repaired or replaced.
3. Clean your refrigerator coils.
Refrigerator coils should be cleaned every six months or more frequently if you have cats and dogs
at home. Coils can trap in dirt and dander, causing them to malfunction. Don’t worry; coils are easy
to clean, and you can do it in a matter of hours.
4. Don’t place your refrigerator in hot places or direct sunlight.
Heat can also affect your refrigerator’s performance, so ensure that your unit is away from direct
sunlight or an area that radiates heat. Never put the oven or burner beside your refrigerator so it
won’t have issues with temperature controls.
5. Fill your refrigerator and freezer with food and drinks.
It is essential not to open and close your refrigerator all the time, so go for a grocery haul once a
week to fill your refrigerator with food and drinks. Cold food and drinks also help regulate
temperature, acting as an ice cube in a drink. Therefore, your refrigerator won’t have difficulty
reaching the desired temperature it needs to preserve its contents.
6. Leave free spaces to allow air circulation.
Don’t overcrowd your refrigerator. Always leave room for air to circulate so each food and drink can
be cooled and preserved properly. This way, your refrigerator won’t work hard to cool down.
We know that even the most well-maintained refrigerator can still develop damages. So, you should
always get an expert Sub Zero Appliance repair in San Mateo for maintenance and repairs to
ensure that your unit is in good hands and will come out better than before.
Why Is Your Sub Zero Fridge Not
Cooling?
Sub Zero refrigerators can also be prone to damage if not properly taken care of. So, we listed why
your refrigerator is not cooling and what you can do to fix the problem.

3.  Your refrigerator fan is malfunctioning.
There are hundreds of fans in your refrigerator that help distribute cold air all over. If one or more
fans malfunction, your refrigerator won’t properly cool. You’ll need to replace your fan, so get a
professional technician to help you with it.
 You don’t properly close the door.
Your refrigerator door traps cold air and blocks warm air from coming inside. If you don’t properly
close the door, cold air escapes and warm air seeps in, increasing the desired temperature. Always
check your refrigerator door. If it’s properly closed yet, you still have trouble with your temperature,
its time to get an expert to evaluate your unit and find out what you need to do.
 Your thermostat is set too high.
Sometimes, we forget to check on our temperature controls and panic immediately. So, before
checking for malfunctions and damaged parts, check your thermostat. If it’s set too high, then your
refrigerator won’t cool. But, if it’s set correctly, it’s time to check for damages that would need to be
repaired immediately.
 Your refrigerator coils are dirty.
Don’t neglect your refrigerator coils, for they can quickly get dirty. Dirty coils can affect the internal
temperature of your refrigerator, which can be one of the reasons why your refrigerator is not cooling
properly. Always follow the manual on how often you need to clean your coils. This way, you are
always at ease with your refrigerator.
 You don’t notice error codes.
Error codes are signs that your refrigerator is malfunctioning. But, we often don’t notice these codes.
Therefore, regularly check your control panel to see if error codes appear on your refrigerator.
For repairs and maintenance, always seek professional Sub Zero Appliance repair in San
Mateo to ensure that your Sub Zero units have the best performance after each repair.
