it's 2:45 am.......

and i cant sleep thinking of this stupid turbo-air 2 door freezer i put a
compressor in a couple weeks ago..after i did the work i told the customer
to never call ME again on this pile!..( i havent billed him yet) he calls me
to say he's sorry but the thing is running at 20*.....

this thing has a 2 part cap tube and the one that runs through the wall is a ice ball
at the evap and cold at the connection where it comes through the wall and connects
to the cap tube going to the compresor.

have any of you guys replaced said cap tube that runs through the frickin wall?, and
what are the chances of blowing CO2 through the tube to clear it?

*yawn*

try just cutting the infeed end off as this is normally where blockage is. just shorten it by an inch and try it.

We typically run a new cap tube up the back wall, drill a hole through the box, and then silicone the penetration afterwards, its actually not too bad. I've done it on several True's but never on a TurboAir.

Do you think if you buy only the upper half of the cap tube you need, you will get it for half price. This is the only OEM with a two piece cap tube.

Did you change the filter drier? Sure you have the correct charge? About clearing a captube it depends what is blocking it. I've only cleared a catube that was blocked with oil.
I think there are too many bends in the suction to try and send a cap up inside the tube.
I run a new one like trippint inside but I run it with a new suction line too. If you cover it with some metal they will like it better.
I don't want to discourage you but its gonna be a PITA and a lot of time if you were never going back.

In my experience, your wasting your time trying to blow it out. Assuming that you cut off 1 inch of cap tube when you changed the dryer and drew a 300-500 vacuum, then the cap tube is probably waxed and only thing left is to change it.

Have you considered just changing the cap tube between the drier and the sleeve?

When we did warranty work for TA, had a cooler that had a clogged cap tube. Tech support told me to cut at the sleeve, blow nitrogen through both ways to try to see what section was restricted. The drier side was restricted, they sent out some cap tube, changed it, and it actually worked.

It may have just been blind luck though.

aramas, turboair suggested replacing only the visable cap tube,,,

itsiceman, yes i replaced the filter, and weighed in the charge.

76olds, ill try unsoldering the cap tube and blowing both ways...

For those who have never seen a TurboAir two-piece cap tube, here's an image from their TST/TUR service manual which clearly shows the sleeve referred to earlier:

is there two different sized cap tubes and this is the reason for the "sleeve?

can i get a link to the above??

I don't know about the sizing of the cap tubes, but here's that manual:

Well shoot if it a small under counter what is the problem with changing it
I thought it was an upright where they get foamed in the whole way

[primmers]

no, im working on a up right reach in freezer tsf-49sd/bk4f0302

i talked to a chic this am at turbo air, she said to blow it out, i laughed and asked to be connected to parts..
i listended to elevator music for 10+ minutes and hung up..

also i did change the cap tube from the filter to the "sleeve" some time ago..that part is clear, its warm, where its cool it from the sleeve foreward
to the ice ball at the evaporator..
