I have three refrigerators which have been unplugged for more than a
year. When I tried to use them by plugging them in, none was cool though
the compressors were all running. Is this a normal behavior, losing
freon if not being used for a year or one and half years?
Are you sure they lost freon? It is common for window air conditioners
to sit for 9 months between uses and nothing is lost.
Check to see they are not blocked by mouse nests on the coils. fans not

They are a completely sealed system and I don't see how them not
running would have any effect. They weren't stored laying on their
sides, then plugged in, where they? Laid on side, the refrigerant
can wind up in the wrong place. Most I think if you put them back
upright for a day or two before plugging in, it will redistribute
and be OK.
They are a closed system and should never loose the 'Freon' ( refrigerant ).
When they have been off for a while, it may take a while for them to cool
down. Did you wait over night ?
The will start cooling when you turn them on ,but just slow.
The only other problem I can think of is that if you laid them on the side
and some of the oil in the compressor ran up the tubes. If you did lay them
down, they should be stood up for about a day before starting.
While I doubt it, there may be a timmer on them so the oil in the compressor
can heat up before starting.
Freon (capitalized) is a brand name, like
Forane, Genetron, or Isotron. Each of these
is a brand of refrigerant.
The refrigerant tends to dissolve in the
lubricating oil. The unit may need to run
a day or two to get to temperature.

When you say it was running, does that mean that the compressor was
running continuously or just that it was plugged in? Are the condenser
coils warm to the touch? To have this happen to 3 is very strange.
How old are they? Are they all the same, or different brands/models,
Two of them are of the same model. They are about three years old. They
were used in a restaurant. The other one is a different brand. It had
been used in an office for more than five years without any problems.
Because we moved the office and closed the restaurant, they had not been
used for more than one year until about a month ago when I tried to use
I have another refrigerator which is identical to the two. Once the
restaurant was closed, that one was moved to my kitchen. It has been
running since without problems.
I find it strange that those three that had been unplugged for a long
time would not cool.
Is the compressor running? I did not really check it. I can only tell
that when plugged in, they made the same noise they made when they were
working fine. I'll check tomorrow to make sure compressor is running.
Wish I could be more help. I can think of a few
tests, but none that I can run from my computer
keyboard. Perhaps you have a friend who has these
Are you sure the compressor is running? Some times,
fans can make a similar noise. What's the name plate
say for refrigerant charge, and running amp draw?
Is the unit amping properly?
Nice thing about working on a unit in person. I can
usually tell if it's just fan, or if the compressor
is running. Some times the start relay gets weak, and
the compressor only tries to start. Could be any of a
few things gone wrong.
Hot compressor means the compressor is getting power.
Does the compressor hum, or does it hum, pause, CLICK! and
then hum a few seconds later?
If possible, touch test the black tubes coming
out of the compressor. Are the tubes different
temperatures, about six inches from the comp?
(Go lightly, some times the tubes can be hot
enough to hurt.)
