ANSWER THIS...?
*******************
"Has anyone come across capillary blockage using R134a. 

A large Amana fridge/freezer only 10 months old has given up the ghost. First signs of trouble was 
ice in the milk and then total defrost. Had a line tap on the thing and registered suction pressure 
@ -20psig!. No loss of charge and after recovering couldn't get nitrogen all around the system. 
Seems that the capillary is well and truly blocked. 

Spoke to a friend engineer and he said that in his experience this had happened quite a lot on his 
jobs and it appears that the gas causes the oil to flock and the capillary then "grows" a lining 
until there is just no free space left. 

My theory is that the compressor was left open for a long time during installation at the factory 
and the oil has been contaminated with moisture. Can't be sure though as I haven't had the 
compressor out yet to do an acid test or oil test. 

Any thoughts or experiences would be welcome"

591 registered members (in addition to the thousands of 'guests' that pop in…).

Hot topics currently being discussed in the forum (415 threads):

-	"…the main question I'm asking here, what if the valve selected was a little undersized and to 
meet the required capacity for a given dP and liquid temperature the superheat setting had to be 
reduced. For any subsequent low load condition such as fan failure or iced coil, would this 
undersized valve with a compensating low superheat adjustment have a greater tendency to floodback 
in comparison to a correctly sized correctly set TEV ?"

-	"Does anyone know where I can get info on converting an electrical fridge to gas, as we are 
moving to where there is no power (in Australia).  Thanks for your help"

-	"Anywhere you go these days, you come across cabinets controlled by those small, neat 
controllers... These are usually programmed and probably don't ever need to be reset again.  But 
what if you have to?  And you're faced with an unfamiliar make Eliwell, Lae, Carell...(are the 
recognisable makes)?  I keep a set of programming parameters for each one in my van.   What do you 
do?   Is there a magic formula dealing with these things or am I becoming paranoid for nothing?"
