Duh. WAKE UP. The refrigerant is hot or warm in the orifice in the choke
point. It's still compressed there. Ain't no way ice is going to form
there.
Debris blocking it maybe; ice - NO! Only when the refrigerant exits the
choke point and begins to expand does it get cold enough to freeze
water.
This happens AFTER the choke point and not at the choke point.

Is everybody on RBC stupid? Are they all Bruce in Bangkok clones or
something?

Here ya be:

"Moisture in a refrigeration system, directly or indirectly, is the
cause
of
most problems and complaints. First, moisture can cause freeze-up in a
system.
Moisture is picked up by the refrigerant and transported through the
refrigerant line in a fine mist, with ice crystals forming at the point
of
expansion."

Ah HAH! The point of expansion - EXACTLY! The refrigerant only begins to
expand AFTER the choke point. Up to the choke point, the compressed
refrigerant is actually warm.

Not in an overcharged system.

EXACT-****ING-LY. If you were capable of reading with comprehension you
would have read my saying exactly THAT. I said to bleed some excess pressure
from your system and enjoy a working system even if you refuse to acknowlege
my excellent advice, PUTZ!

After it gets past the choke point it can then
expand and become cold as it expands. If you look at the evaporator you
will
see a couple of interesting things. The large diameter copper tubing from
the compressor chokes down to a spiral of very small diameter copper
tubing
(choke point) which spirals around the larger copper tube. The whole
freaking thing has warm refrigerant inside...

(Snip)

You sound like a Republican claiming credit for the death of Osama bin
Laden,

I am familiar with both over charge and under charge in a refrigerator
system.

The point you are overlooking is the manner in which the various tubes are
related. The cap tube does not suddenly appear as a coil of very fine
tubing
just ahead of the evaporator. It is inside the tube that runs from the
discharge side of the evaporator to the suction side of the compressor. If
the
unit is overcharged then liquid is still in the evaporator and inside the
large diameter discharge to suction tube where it continues to flash and
cool
the refrigerant to well below the freezing point of water before it
reaches
the evaporator. There is no "choke point." The cap tube terminates at the
copper to aluminum transition where it is free to expan. Visual evidence
is
frost on the tube inside of which is the cap tube. In a dry system over
charge
will degrade performance and increase power demand. But it won't stop the
system from running and cooling. Serious overcharge can put liquid
refrigerant
back into the suction side of the compressor which is not a good thing.

Freaking clueless moron! Won't listen to factual information. Insists upon
making up his very own laws of physics.

No wonder he goes through life bothering everybody with the most simple of
problems anybody with half a brain never experiences.
