In continuing with our theme of finding ways to save you
money, Expert Home inspections is offering this installment of our blog with
some tips and maintenance items that will help ensure your appliances are
running as efficiently as possible.
Despite the fact that we all use our refrigerator multiple
times a day, the care and maintenance is often neglected, and yes, there is
regular maintenance that needs to be done to keep this important appliance
running. The other items listed in this article are more along the lines of
“best practices” on how to use the fridge and freezer properly.

Cleaning the Coils
Every fridge or freezer has a coil unit which is designed to
dissipate the heat the refrigerant is pulling from inside. You can think of these coils much like the
radiator on your car. The hot coolant
runs through the coils and transfers to the air surrounding them. Over time, these coils collect hair, dirt and
lint, preventing efficient air movement and heat transfer. This will cause the compressor in your fridge
to run longer than necessary. Ultimately this will not only cost you more in electricity
but will cause more wear and tear on your appliance, causing it to fail sooner.
These coil units are located either on the bottom, or rear
of the appliance. For rear mounted coils, just carefully slide the fridge out
to expose the coils on the back. For bottom mounted coils, they can usually be
accessed by either removing the lower front cover, or from the rear of the unit
by again just sliding the refrigerator out. Once you have access, use a soft
flexible brush that will slide behind and around the coils. These are usually
available at most home improvement stores for under $10. Using a vacuum and the
brush, continually wipe down the coils and vacuum the dust until clean.
A final note …. if you have a rear mounted coil, be sure to
leave at least 1” or 2” between the coil and the wall to allow for proper air
movement.
Defrosting the
Freezer
While most modern freezers are self-defrosting, if yours is
not, this will also be a regular maintenance item you will need to perform. To determine
if you need to defrost, the check is pretty simple… open your freezer. If there
is a build up of ice on any of the walls or shelves, you need to defrost.
When it comes to defrosting a freezer, the list is far
greater for the things NOT to do than the rules to perform the task. The
biggest tool you need for this project is patience, that’s it. Simply turn off
or unplug your appliance; empty the contents into a cooler; open the door and
wait. When the ice has melted; use a mild dish soap to clean the inside.
The biggest mistake people make is getting impatient or
rushing the job. There is probably a limitless list of shortcuts to make this
project go faster, from hairdryers, hot packs and boiling pans of water to
vehicle window scrapers and screwdrivers. Sure, these tips can cut minutes off
the time it will take. But…plastic walls can melt, crack or deform and pics and
scrapers can easily puncture soft freon lines, walls or seals. And any of these
things can make your freezer useless. It is much easier to leave the freezer
open and off and find another project to do while the ice melts.
One last tip - have a few towels on hand to keep the melting
ice from making a mess on the ground.
Cleaning the Drip Pan
If your fridge/freezer is a self-defroster, then it will
also have a drain hole and drip pan. In a frost free or self-defrosting freezer,
the freezer will occasionally go through a warming cycle to melt off any ice,
which then drains to the drip pan under the appliance. The drain hole and the
pan itself can get built up with sediment and clogged over time and should be cleaned
out regularly.
You can generally access the drip pan either by removing the
front lower cover, or by sliding the unit out and accessing it from the back.
If the drip pan is not easily identifiable, refer to the owner’s manual or
search for the information online.
Level the
Fridge/Freezer
This may seem insignificant but making sure your freezer is
level can improve its efficiency and extend its life. There are two major
systems that can be affected by the unit being level, the compressor and the
sealing of the doors. If the appliance
is not level it can cause the compressor to experience excessive vibration or
mix the Freon and oil in the system, ultimately shortening its life. Additionally, if it is not level, it can put
stress on the door and cause the door not to close or seal properly, causing the
appliance motor to run more than needed.
Most units have at least two of the feet that can be
adjusted up or down with a pair of pliers.
Check your user manual for the exact adjustment points.
Check and clean the
door seals
Making sure that the doors seal properly is more than likely
the single largest potential loss of energy efficiency in a fridge or freezer.
The pleats in these seals can get caked with food crumbs and sticky bits of
food effecting their position and flexibility.
Using warm water and vinegar will clean off all food
residue, help prevent mold growth and will be safe for the seals. If any part
of the seal is cracked, a new one should be ordered and replaced.
Best Practices for an
Efficient Fridge/Freezer
Because of how a fridge and freezer works, and based on the
laws of thermodynamics, simple science dictates that a full fridge or freezer
will operate far more efficiently. As an example, for most freezers, if you
fill it half full and turn it off, the food will stay frozen for about 24
hours. If you do this with a full freezer the food will stay frozen about twice
as long. A solid frozen mass will hold
the cold temperature longer than that same cold temperature will hold in an empty
fridge. So, always keep your
freezer/fridge full, even if that means filling some jugs of water.
To properly and safely store food, the refrigerator should
be set between 38 and 40 degrees Fahrenheit, and the freezer set at 0 degrees.
Using a food thermometer, make sure you are not cooling your food more than is
necessary.
Finally, and while this may seem obvious, try not to stand
in front of the fridge with the door open! There was a reason your mother used
to yell at you about that!!
