I have a 12 cubic foot frost free fridge (Camco Model CRT1200VLT-1)
whose freezer isn't cold enough to keep meat frozen. This is one of
those GE apartment size fridges where you have to take out the freezer
floor to get to the evaporator, evaporator fan, defrost heater and
defrost thermostat.

I can feel a draft in the freezer compartment, so I know the evaporator
fan is running. On this fridge the defrost thermostat diverts power
from the cold control to the defrost heater, so if the evaporator fan is
running, then the cold control is calling for cold, the evaporator fan
and compressor are getting power and therefore the fridge can't be stuck
in defrost mode. The compressor sounds like it's running when I use a
mechanic's stethoscope on it and the line between the compressor and the
condesnor coil behind the fridge is hot to the touch. Still the freezer
compartment isn't getting cold enough to freeze water or keep meat
frozen.

I replaced the cold control, but that didn't do any good.

Until now, this fridge would make a loud knocking sound when the
compressor stopped, presumably due to a broken suspension spring inside
the compressor housing. Now, the compressor and evaporator fan seem to
run continuously 24/7 except for defrost cycles.

I'm coming to the conclusion that the refrigerant must have leaked out
of the sealed system on this fridge, and I need to buy a new fridge.

Is there anything I might be missing? Should I get an appliance repair
tech in to measure the pressure drop across the compressor to see if
that really is the problem, or have I covered all the bases already and
proving that it's a lack of refrigerant is just a waste of money?



Is the condensor behind the fridge? Is there a bunch
of horizontal back and forth tube, and wires that go
up and down?

If this is the case, the top 1/3 or 1/2 of this
assembly should be hot when the compressor is running.

If not, then very likely low freon. Please write back
and ask questions if you wish.
