Thank you for showing to cut the new dryer ends nobody else showed that part.

That pipe is kinked

As a school-trained licensed and certified HVAC technician. This is working the easy lazy way, which sooner or later catches up to you. Referring to the refrigerant as "Freon" gave me the hives. No deburring? Lazy. The bending is so badly made it kinked the tube, which produces flow turbulence. Not protecting the filter from the brazing heat? Nice way to possibly damaging it. Having nitrogen and planning on using it, but not flowing it during the brazing... oh boy. Carbonization in the inside. That filter might need replacement soon again. But if you only didn't refer to the gas as "freon"....

What kind of solder material are you using to solder?

[@peniasnyirenda8095]

Nice job my fellow technician

[@Cholla-Ranch]

Very helpful. Thank you.

I have a problem. When I try to move a refrigerator from one place to another on the backside the oil inside the compressor return back to the filter and damages it. Is that video help me to avoid that?. Any other solutions could help to prevent the oil from going out to the filter and damage it like a one-way valve or other ideas. Please suggest me solutions. Thank you.

How about dryer on any reefer unit. Thank you

Just wondering : why does the filter need to be changed when replacing a compressor? Is it something that can be done in stages? (change filter on day 1 and compressor on day 2?). Thanks

[@vihayster]

filter dryer is there for catching moisture, chemicals and copper oxides created during brazing process (because they don't use dry nitrogen at time of brazing). After years of work when you change compressor that filter is almost clogged out and needs to be replaced. If you don't replace it, it may work few years OR only few weeks before gets clogged. When you install new compressor you create even more oxides that have to be filtered. Both compressor and filter should be brazed at the same time so the system is sealed quickly to prevent moisture getting in. New compressors and filters comes with sealed both ends so compressor oils (which very often are hygroscopic) and filter's desiccants are protected until installation time.

My dryer filter is very cold any ideas ?

[@markspc1]

Your solder is bubbling up, too hot frame.

[@kcengiz363]

How do you understand you got problem in the filter dryer?

[@davidcromer2675]

95% of the time that’s the clog if you have blockage. There are ways to test. You are going to replace that anyway during a service where you are going into a sealed system.

Hack, using wire strippers to cut the cap tube, and drier.

[@Skoalman8685]

You kinked the pipe and then didnt even talk about pulling a vacuum lol.

[@johnflanagan4103]

No nitrogen purge while brazing. What a mess.That cap tube will plug up.😨😳

[@vihayster]

yeah...seems to be new normal. I haven't seen any videos with nitro in use during brazing refrigerator components. I think everybody assume that filter will catch everything, lol

[@christopher6147]

@@vihayster I haven’t seen any either. strange

[@reefermadd.2204]

Shop mentality . That was the lazy way of doing that.

[@syedali1077]

Brazing job is poor

[@pavansampuri6432]

Induction brazing better than this
