Excellent video. I can't thank you enough. I have a refrigerator that has the possible yoder loop leak and I was wondering if this can be by passed. Now I know it can and the solution for preventing the condensation. Keep it up. Fan for life. Thanks
This man is an amazing instructor ,he knos what he is talking about it. I have a quick question I have a refrigerator in a good working condition ,I installed the piercing valve and my low side pressure is 40 psi, and he said is supposed to be 60-70 psi . what does it mean?
Sorry for late reply so many videos don't have time for many responses, when you got that pressure reading was the compressor running? measuring pressure should really be done with the unit running. Please respond on our website all communications go trough me if you want to talk further.
Bypassing the Yoder loop affects subcooling. I did it in a Subzero and I could not get the freezer to go below 10 degrees no matter how I adjusted the charge. I ended up installing an external Yoder loop to solve the problem. I've also bypassed the loop on smaller refrigerator with no issues. It depends on the length of the loop
The valves in most compressors are reed valves. A reed valve is just a thin flat piece of stainless steel, for both the intake valve and discharge valve. Depending on the position of the piston in the compressor it is possible for the system to equalize faster than average as the valves are not completely sealed or slightly warped. Here is a link to a teardown video showing the reed valves inside a compressor. ua-cam.com/video/3Uwx-_VecHo/v-deo.html
Why is it that i dont see many appliance techs using Smart probes? Fieldpiece joblink probes, vs manifold and hoses? Also, when brazing with Oxy/Ace do you all prefer the Smith Jewelers torch? Which is small and compact?
I think in small refrigerator systems may cause more problems than repair. But if means saving a $14,000 refrigerator I would prefeer to repair as much as I could and only use if all other options did not fix the problem. TMM Appliance
Some they open the back body of the refrigerator to access the pipes then check for leaks and do brazing. Some recoil the whole evaporator coil and join with the capillary tube. Can I also get like a wiring schematic of different types of refrigerator since some have an internal condenser coil and some have external condenser coil, some they join copper pipe with aluminum pipe using lockring which is more likey to have leak and they use also steel joining it with the internal pipes.
Some they use epoxy to close the leak , some q bond, etc so I wanted u to show us how to use also this. Some of these things they have instructions on how to use them but some don't have
Hi. Can anyone tell me what type of Bullet Piercing Valve he's using with the built in valve stem? I noticed when he hooked up the low side gauge, you can hear a little bit of refrigerant escape from the system.
leaks are better tested with pressure, although you can not fix most yoder loops, vacuum will say a tube is leaking same as pressure, but a vacuum could risk pulling moisture, dirt or other things into the system, where pressure like nitrogen would leak out reducing that risk
How much would the customer pay for a leaking fix/refilling etc.? I'm a fraid in Germany it might be cheaper to just get a new fridge instead. Even though I'm not happy with throwing away stuff if I don't need to.
can we increase pressure from external air compressor to around 300-500 psi to detect leaks? in that way even a weak spot on the pipes or joints can crack, etc, self admitting weak points. Because the higher the internal pressure, the easier to detect holes as they makes alot of sound when air is escaping through it in a very fast rate.
43:05 or 49:30 - every time you zoom the camera in I have to turn the volume on my computer down because the video volume increases. Why is that? And can you do something about it for future videos?

How long should it take for pressures to equalize low to high after shutting it off.
Dear sir, My brand new Samsung Top Mount Freezer Refrigerator RT60CG6004WW White has such a small leak that it takes about 2 weeks for the gas to leak completely. It was repaired by 3 technicians but of no use. Samsung service center also refused to repair. Can you please guide me that what should I do now
Whirlpool offers a dye drier as well for r134 systems. Cannot use dye on r600. Generally we nitrogen charge and listen for the hiss to check for leaks. Since you didn't find it in the rear I am guessing leak at the evap. Maybe the heater rubbed or burned a hole in the evap
Hello, I have a question. Can heart failure be checked with air or only with gas? The second question is about gas, is mixing gases not a problem? Because R134a was first filled here, and later Nitrogen, by creating a gas mixture, does this not have to be reversed and filled with the same gas? Because the air is free at high pressure, we check the heart failure at the maximum test pressure, and if it is, we repair it, vacuum the device and fill it with gas. If it is filled with gas, but the system is leaking, I cannot use a gas flame directly, because the explosion is dangerous, on the other hand, in the case of a pressure test with clean air. Greetings from Hungary! And thank you in advance for your answer!
Sorry not sure what you mean about heart failure. Bit it is a common practice to use a small amount of a trace gas with nitrogen to test for leaks. Electronic leas detectors can not detect nitrogen this is why tlwr add refrigerant. Once the leak is identified the nitrogen is evacuated from the system and charged back with r134a. Nitrogen js an inert gas so will not cause any problems qhen mixed with refrigerant. This is done to raise the entire systems pressure to test for a leak. It is not used when the compressor is operating.
38:10 - I can hear you better when the camera is zoomed in; but, I can barely hear you when it is panned all the way out. That's weird! 40:51 - Compare that to right here 41:00 - and here: 41:15 - and here: 43:09 - Drastic difference! I'm glad you have caption turned on so I can understand you when you voice drops to nothing.
watched the whole thing! ty 👍 lots of useful info i was wonder if you can make a video on getting a refrigerator to 500 microns and maintaining 500 microns, iv looked everywhere and i only ever find A/C examples but not household refrigerators

You have my complete attention.The man in this video explains the operation of diagnosing comman problems of a refriderater.
I am new to HVAC and just wanted to say that your videos and UA-cam channel have been so very helpful. THANK YOU!!
This video is gold for new sealed system technicians.
If you had your own business would you be doing sealed systems?
Absolutely excellent. I’ve been learning HVACR for about 3 months with a book and this brought much of it to life.
I respect you teacher, I learn a lot from you as a beginner, greetings from Greece
I am a 48 y old MSC mech engineer, and this guy is my teacher and i would be happy if he was my boss in any job
Thank you sir for sharing this awesome video
Absolutely amazing Teacher! Thank You for your time and effort!
Awesome video man 😎
Thank you guys for all you do. Can’t wait to add appliance repair to plumbing company
Your welcome
Good luck 😂

What do you call the clamp used for isolating a joint leak? I want to purchase one but can’t seem to find it.

Here, I saw the Blu gage went up quickly when you switch off The compressor, does that mean it's Valve not good?
Thanks.

What are your thoughts on stop leak?
i think thats a good question and a very valuable invention idea 😊

Does the service port of the compressor normally balance out same as a suction line when the compressor shuts off?
Yes
Service port and suction line are exactly the same thing and are interchangeable you can put suction on service port and access valve on suction line.
Thanks for posting

BPV31 SUPCO Bullet Piercing Valve for 1/4", 5/16" and 3/8" Tubing 3 in 1 Access This is the piercing valve we used in the video
Nice 👍
Couldnt you cut both sides and test pressure in the yoder loop in a vaccumm and see if the loop holds pressure or not for a leak test?
leaks are better tested with pressure, although you can not fix most yoder loops, vacuum will say a tube is leaking same as pressure, but a vacuum could risk pulling moisture, dirt or other things into the system, where pressure like nitrogen would leak out reducing that risk
Can a clogged dryer/ filter cause the compressor to cease and cycle ??
How much would the customer pay for a leaking fix/refilling etc.? I'm a fraid in Germany it might be cheaper to just get a new fridge instead. Even though I'm not happy with throwing away stuff if I don't need to.

evaporators in refrigerators are mostly made of aluminum, anything over 100PSI nitrogen will possibly damage the evaporaor
Yes, you could do that and the chance is that you system will explode because of the pressure. But in that case you finally found an obvious leak.

As far as I know heart failure can be checked with propane and a torch.
Can u make a video showing us how to use leak sealants, there are 9 types of leak sealants.
How fast should low side pressure drop to operating pressure after turning fridge on ?

Let me look into that might be this week
Interesting. Can we get any EBook
I am currently working on online training, recently posted a sealed system 5 chapter learning for our members,
Ton ist ein bischen leise.
for sure not stupid people get me out Utah please
Go back to school and learn proper grammar.
A good idea is to fill the compressor with water before regassing then there is no need to vacuum
😅
Indeed. Naturally! salt seawater is the best 👍 But it you don't have that you could add biological sea salt.
