Additional things about a refrigerators' energy efficiency
--------------------------------------------
1) Replace the fridge door seal if it is damaged or broken - i.e.
eliminate any air leak source.
2) Placing the fridge in the coolest part of the house, having low
ambient average room temperature helps.
3) Placing the fridge so it has an adequate amount of space for air
circulation around the external cooling fins/surface. and keep those
coils free of dust.
4) Use a temperature gauge to set freezer to no lower than 0 degrees
Fahrenheit - that is don't work the freezer any
harder than necessary ( 0 to 10 Fahrenheit should keeping ice
cream stable/hard )
5) Do not open the fridge door too often and keep any time the door is
open to the shortest amount of time.
6) monitor your fridge's energy usage using a kill-a-watt meter
( normally a fridge uses more
energy in the summer than in the winter because the ambient room
temperature is warmer,
for a reference point - an energy star 18 cubic feet refrigerator
uses about 383kwh/year)
7) The most commerically available energy efficient refrigerator size
(energy used per cubic feet)
is normally between 18 to 24 cubic feet. Ice makers, external
chilled water dispenser have
a tendency to make a refrigerator less energy efficient and less
reliable.

It's amazing what you can do. If...
you put your mind to it.

7. A 24 foot refrigerator is very inefficient if you can't fill a 5
foot refrigerator. Buying extra stuff and keeping it cold is not too
frugal either.
6. A kill-0-watt meter doesn't do diddly for you if you already own
the refrigerator. All new ones are clearly marked for the SEER rating.
5. I need to open the GD refrigerator to enjoy it. It works for me,
not the other way around.
4. I raise and lower the temperature as needed because sometimes I
like to freeze something faster. Other times I turn it down or even
off with the door open.
2. The refrigerator goes in the kitchen. Only a moron would place it
somewhere else to save a few degrees of ambient heat.
1. A heat gun used carefully can sometimes return a deformed seal to
proper dimension.

If you notice the electricity usage varying too much it could be a
tipoff that something's wrong.

Think of it as a guideline - some people don't realize how long they
leave the refrigerator door open.

True.

Very true.

I have a friend who often moved the refrigerator out of the kitchen.
Not to a cooler place just to open up kitchen space, I guess.
Seemed odd at first, but then you could grab a cold drink at the
front door (which is usually where it wound up) rather that having to
go to the kitchen. Women hated it, guys loved it. Saved a lot of my energy!

I moved mine into the dining room. It had been right up against the
stove. Moving it freed up space next to the stove so I could put in
a cabinet and countertop, and have someplace to set hot things
without carrying them all over the kitchen. I'm sure that putting
the fridge in a much cooler location helped with my electric bill,
too.
