Fridge/freezer not cool.

Hello
Welcome to fixya.
I'm Huuum and happy to assist you,

I believe your problem is an old thermostat or compressor !
How old is it?

My advice is do not put good money into bad!
A new fridge will pay for itself in a few years by using a lot less electricity!

Here is an interesting report I just read!

Repair or replace?

When to pull the plug on your old refrigerator

It nearly always makes sense to undertake simple do-it-yourself repairs,
such as replacing a gasket on a refrigerator or a freezer.

Typically, you'll also find a troubleshooting section for more-serious problems
in the owner's manual.

Should you pay for a repair or buy a new model?
The answer depends mostly on the age of your refrigerator,
how much you bought it for,and the cost of the repair.

Follow these guidelines:

When a repair makes sense.

If your refrigerator is under warranty or less than four years old (three years for top-freezers),
paying for a repair makes sense.
Note that refrigerators under warranty might require service from a factory-authorized technician;
readers have found them on a par with independent repairers.

When a repair might be a wise choice.

If your refrigerator is out of warranty and is four to seven years old,
it might make sense to pay for a repair. Customers generally pay $100 to $200 for a repair.
But you might want to buy a new model even at this stage,
given that today's models are quieter and have added features.
Higher energy efficiency is another plus: Energy Star-qualified models made after April 28, 2008,
are 43 percent more efficient than conventional models built before 2001 and 56 percent
more efficient than those built before 1993.

When it pays to replace.

The repair costs more than half the price of a comparable new refrigerator.
Data also shows that it doesn't pay to fix a less-expensive top-freezer refrigerator
six or more years old or a bottom-freezer or side-by-side eight or more years old.

Thanks to better recycling programs, less than 10 percent
of a refrigerator you replace is likely to end up in a landfill.
Thanks for giving me the opportunity to help!
