Flushing fridge condenser-cappilary flow test

[romac]

Q.1
Would some one know if condenser on a refrigerator and its door heating loop gets partially plugged up by R134a or by any other refrigerant which would require flushing and what is the best flush agent to use?
Q2.
Is there a way to flow test disconnected capillary tubing to determine if it's partially clogged?
Thanks in advance.

R134a is quite a self cleaning refigerant and will often block up capilliaries,filters can also be the culprit if the medium gets through the inner gauze it's also possible if they have been regassed a few times.
You would have to de gas and then dismantle filter unit and visibly inspect capilliary,it's clear to the eye if there is sediment usually,it is possible to pull a vacuum in reverse direction through the capilliary and also a cleaning agent.
Pain of a job and is it worth it ?
Might be worth pricing up a new evaporator and capilliary complete before spending excess time on what might be a fruitless excersize.

I always recommend just replacing a plugged cap tube.. If that means replacing an evaporator or heat exchanger its well worth it.. Who knows what passed before it actually clogged and is just sitting in the evaporator or heat exchanger....

Plus it is already difficult enough to flush through a cap tube. So just remove your cap tube and bypass your compressor and flush just to make sure everything is clean.

There was an easy way - but it isn't PC anymore
