I'm feeling anxious about re-gassing of my car's air conditioning system and was 'floating about TH-cam ' for inspiration and ideas ,as you do, and was mesmerized by your video. The music and calm, slow rhythm of your work mellowed my mood. For that I thank you 🙏 lloyd.
Also when i cleaning the system i can use second compressor as my vacuum pump by using thinners and liquid flush, so doesn't these affect the second compressor when vacuuming because they will enter into the second compressor not all but maybe little. And the thinners and liquid flush will mix with compressor oil. Again when blowing air to remove the remaining thinners and liquid flush you pressure it to the highest level on the gauge.
You'd make something wrong, when you charged at the yellow hose, you supposed to remove the air from the hose by opening the right side wheel and close it again to remove the air.
So the second compressor its air being pressured qnd not R134 a and again on the second compressor the suction is also has access valve just like the discharge and charging side and lastly u can use this method on R600 a
you really should use nitrogen. oxygen is flammable. and when you braze without, like it looks like you did the first braze you made, you now have debris inside your lines from the oxidization, which can cause damage to the compressor later.
Instructional video thank you for sharing! Two questions: 1. Do you only charge through the low side for this repair? Don't believe I ever saw you use the high side port on the gauges. 2. Could I use an air compressor to charge the system with air? Thanks
It is best to charge system with nitrogen to test for leaks to prevent contamination from water and other stuff in the air. Thus guy is no professional. He likely put water in the system using air which could plug the filter dryer and corrode the tubing from inside out. Pull into deep vacuum for 5 minutes to remove condensables and hold in vacuum for at least 20 minutes before adding R134a. If guage moves up even a little, then you still have a leak. One should have a scale to weigh the amount of Refrigerant being added. Some auto parts dealers will rent them or even lend them for free if you buy refrigerant and supplies from them. DO NOT use any R134a containing oil, dye or leak sealant for automobile systems. Vehicles use a different oil than home and commercial Refrigerators do. You'd contaminate the system with the wrong oil. Refrigerators use pure polyester (Ester) oil.
If you purge a system of air and water (including your charging hoses) you can use a scale to measure the weight of Refrigerant removed from the tank when you open it. Then open the the HIGH SIDE (keeping low side closed) valve of your manifold with the frig compressor OFF. Thst will put maybe half or more of the needed charge into unit quickly as a LIQUID. CLOSE HIGH SIDE valve. Turn on the compressor of your frig. - REMEMBER low side is meant for return Vapor. Since you'd gave to heat the refrigerant to turn it into a vapor and you don't have the expense device for that - you need to SLOWLY, a SMALL amount at a time - as liquid refrigerant (R-134a). Basically open valve for two seconds -it will instantly jump up to about 45 psi. Let it gradually come back down into a vacuum before adding more refrigerant about 1 second at a time (shake can between each fill. You a typical Refrigerator evaporator at about 0 degrees which is about 3 psi. A deep freezer at about 0 psi (atmosphere). If it's just fresh food cooler or soft drink vending machine or de-humidifier, then pressure should be higher so evaporator won't frost uo. You want A/C at about 45°F. MOST low side guages have an R-134a scale which shows the evaporator temperature at a given pressure
@@isayz762 Invest in a 3 hose manifold set 4 hose is better -with guages. Also get a set of 3 ball valves - available at any auto parts store or AMAZON . Those valves are need to prevent air from getting into hoses when yo remove them. Yes, if you don't have a recovery pump - NOT THE SAME AS A VACUUM PUMP - THEN you need the high side guage and valve to evacuate the system with the Refrigerator's compressor.

You right but this was quick fix on how to found a very small leak and fix it I will make another video on how to do a very full repair on fridge system
Help me brother i bought a new refrigerator but this refrigerator not making solid ice thermostat almost on 7 number i tell the shop kiper but he says this problem will bi solve automatic in 3 days please help me what i do now ?
Thanks for your question. 1. This problem it will not solve in 3 days sorry 2. If the thermostat on 7 and its not making ice in 4 hours this fridg have problem. 3. The good solution for this issue if you have warranty on it take it back and replace it not fix it
Same reason almost the entirety of this video was painful. He did almost everything wrong. If he tried this on a r600 fridge he would have killed himself. Dude is a shade tree mechanic at best.

Sorry for the late response.
Thank you for stopping by my channel and you welcome any time
Step by step procedures easy to understand. Thank you for sharing your video 👍

Do u also use epoxy or pratley to close leak on the evaporator coil especially that is difficult to repair by welding
So the second compressor its air being pressured qnd not R134 a and again on the second compressor the suction is also has access valve just like the discharge and charging side and lastly u can use this method on R600 a
Thank you for the video can anybody tell me what type of gas would be in a smeg fridge freezer And whereI can buy this gas
Did you change the dry filter
No need start fridge compressor when you are pressing with air?
Also this second compressor its a damaged compressor which cannot pump gas but only air or ?
❤❤❤
A small leak likr that, do you think stop leak additif could seal it
Do not use stop leak additive it will cause more problems in the system after thank you
I thiamna hi chu a turu mawle. Mahse nupui mawlh kha aw.
For how long to do a pressure test for leaks on household fridges?
45 minute
hello good video it's more economical way, from nitrogen
you really should use nitrogen. oxygen is flammable. and when you braze without, like it looks like you did the first braze you made, you now have debris inside your lines from the oxidization, which can cause damage to the compressor later.
Great video Moe! But how do you power the spare compressor? I see you ran a power cord but I can t figure how you hooked it up to compressor.
Sorry for being late to answer your questions I will make another video that explain your question soon . Thanks for watching my video
Instructional video thank you for sharing!
Two questions:
1. Do you only charge through the low side for this repair? Don't believe I ever saw you use the high side port on the gauges.
2. Could I use an air compressor to charge the system with air?
Thanks
5-8 psi is too high for a Refrigerator/Freezer using 134a. Should be about 3 psi and 0 for a deep freezer
It is best to charge system with nitrogen to test for leaks to prevent contamination from water and other stuff in the air. Thus guy is no professional. He likely put water in the system using air which could plug the filter dryer and corrode the tubing from inside out.

@@Jake-by9ly appreciate the response and recommendations!
Is there a need for a high side port connection or just low side?

when you vacuum the fridge through the low pressure side do you open the high pressure side or is it only the low pressure side open?
Of course you have to open it to
Even if this does work what do you do if you don’t weld or have all this equipment? Not really easy unless you have skill and gear to do this!
During pressurised the system for checking leakage, we have to start only old fridge (second) compressor. I.e. not to start both compressor?
Right never start the 1st compressor during the the fix only when you start to charge the system
Damn how u come up with second crompresor as zat
The red pipe were is it connected
When you do maintenance on small fridge actually you don't need the red Hose you only work with the blue one because it's not high pressure system
Why not changing the drier, on every charge the drier need to be changed
You right but this was quick fix on how to found a very small leak and fix it I will make another video on how to do a very full repair on fridge system
This will NOT work with all types of fridges. R600a refrigerant is flammable and that'll explode with your method.
So they also dot have a proper vacuum pump it alo a makeshift repairs and no extruder thy just let that gas out in to the atmosphere

2. If the thermostat on 7 and its not making ice in 4 hours this fridg have problem.
3. The good solution for this issue if you have warranty on it take it back and replace it not fix it
why didnt you change the filter drier

how to use gas?
Are you crazy?? Do not use a compressor to charge the fridge use nitrogen!
why not? it's a cheap way to fix a fridge and it working until now
It is not a professional way to deal with refrigerator leakage.
Vacume lol
What an absolute joke of a repair, i wouldn't teach my worst enemy this repair job
