- The condenser fan motor stopped working causing the head pressure to rise too high then the aluminum piston rods in the compressor broke. I change the compressor, the drier filter and the fan motor.

HI Jim first i want to thank you for the afford and time you put in to your videos. Out of all the hvac tech who post videos on youtube you are the most inspirational role model for people like me who is just getting in to the hvac field. I know i have a long road ahead of me but watching your videos it gives me hope of someday i will be great as you. Once again thank you Jim for all the videos.
Thanks for your interesting videos. A lot of knowledge being shared in every single one. Wanted to ask you if you have one explaining the wiring coming into that box that has the capacitor attached and how they are connected to the different devices . thanks
I remember 2 different styles of bottle coolers for soft drink bottles. One was a "wet" cooler where all the bottles stood submerged in cold water. These types were inside stores where you'd take your purchase to the cash. The other type I remember was a vending machine, dry cold. The bottles would be loaded by the vending operator who would have the keys. The bottles would be suspended by their necks (there used to be "slots" on the neck, created by having thicker glass rings below the lip of the bottle) in steel channels. You would slide your choice of bottle to the release area. You'd put your change into the vending collector. It would allow you to then pull the bottle straight up and out, then it would lock again. The "wet" type succumbed to leak problems, combined with abuse by shop owners who didn't know enough to monitor the liquid level in the tub area. That and corrosion. The dry type was succeeded by vertical-stacking vending machine, which could hold far more capacity, and took up half the floor space.
A pressure control can save a compressor. Good work, thank you for posting it.
Julio Chavez I agree, with a manual reset. Would have saved compressor. They make tne screw on switchs.
Very nice video and great work, thanks for bringing us along.
DC Rickerson thanks for commenting
I love your vids Jim. Keep them coming. I dont see any harm on the use of leak lock and tape. How is it bad to take that extra step of prevention?
GREAT VIDEOS, KEEP UP THE GOOD WORK, YOUR VIDEOS HELP ME A LOT ON THE FIELD, REALLY GREAT VIDEOS, MARRY CHRISTMAS MR. PETTINATO
Congratolations Jim, from Brazil.
Nice job Jim. I always enjoy your videos.
Jon Hexom thanks for commenting
Nice Job Jim, I work on about 3 a week, Every thing looks great should run for a long time, Again Nice JOB.
Arnie Grote lucky for me the place wasn't open for business, when you're working behind the bar you become the entertainment for some drunk. thanks for commenting
And the drunks seam to know more about how to repair the unit then we do. Been there.
+Jim Pettinato I know what you mean. when I have to drag a bottle cooler out and the bar is open I become the sole source of amusement for the drunk guys. Thanks for the vids. Keep them coming.
Great video Jim
i love watching your videos

Jim, do you flow trace nitrogen while brazing? Just curious, thanks for a great video!
There for a moment I though you took a swig off the liquor . I just got a old RV camper with the old unavailable refrigeration gas should be fun switching it over . Its also has a orifice regulation something I will have to study up on . What would be good to flush out the old oil with ? Thanks again for real world AC education .
nisw1918 you don't have to flush it, just add POE plus refrigerant
Thanks
I always enjoy your videos. I have a question, when you are brazing, do you use nitrogen?
Ron White usually I do, this was just two small brazes, it wasn't worth dragging the big bottle out for.
Thank you
Another Great video Jim. Thanks for posting.
Great video Jim as always. Quick question about the tape you use, is it standard Teflon or a refrigeration type tape leak lock brand ect. In the video it appears to be blue? Thanks Jim.
+Chill Refrigeration,Heating & Air Conditioning LLC you can use standard, but it tends to be thin, this tape is called "Blue Monster" I got at my supply house.
Ty Jim
Thanks for sharing your videos!!! I really learn a lot from them.... I'm having an issue with one of our walk in coolers... Normal low side pressures(57-60) with high head(spikes up to 340) its a 404a unit that was worked on in November.... My initial though was an overcharge since it's been blazing hot down here in central Florida(100 degrees)... Any thoughts??? It runs fine for awhile then eventually trips the high side pressure switch.. Any information would be appreciated.... Keep up with the great videos!!!!
Armando Torres first wash the condenser, second, I had a Subway with a yr old walk in cooler, head pressure was high, the condenser fan was turning but slower than it should, I found the motor had a small rectanglular capacitor on it that was bad, I changed it and it worked good. If the head pressure keeps going up and down I would check the expansion valve, is the bulb clamped real tight, is the evap too small, that would cause the valve to hunt, is the evap coil clean,
Cleaned the condenser coil today and checked fan capacitors... Its a dual fan condenser... One was reading out of range(2mfd 10+- reading 1.3), but it doesn't appear to be running any slower than the other... The evap didn't appear to be clogged with the naked eye... Probably due for a cleaning though... I'll check the sensing bulb and look into replacing that one capacitor tomorrow... Thank you so much for the response!!!
@@armandotorres626 just wondering what became of this issue. Did you get it sorted out. Yes, it's been 4 years, so, you probably don't even remember this issue, but, incase you do.. I'd like to know. Thanks
Thanks for another great video. What is the number of the Turbo Torch tip that you used?
Pops McCartney thanks for commenting
Excellent Work I was tech also . Have a good day. 7/9/2021
Another good one Jim.
rasta1kikker thanks for commenting
Thanks for recording and posting the whole job. Greatly appreciated!
When you take the brazing equipment out next time, would you please do a short video on your method of brazing? I see you use flux and would like to learn more. Been soldering for 10plus years but new to brazing.

admiro muito seu trabalho e a qualidade ,aqui no brasil ,é muito difícil com a qualidade das ferramentas e peças
Jim ,
Was the beer cooler made by True?
Or a different manufacturers, just curious.
Thanks ,
Ralph
Ralph Hernandez I think so, thanks for commenting
Great job.What was the incoming ambient?
Eagle Mech Services Hvac/Refrigeration 70-74
I was wondering why the high head presseure at 74 ambient.
If you don't change out the oil and just add to it, isn't there a chance there might be too much oil in the system or isn't that a problem? should you dump some out of the compressor?
Thanks for the videos.
amtpdb1 change the oil in the compressor, thats the best way, I've done that alot. But when its a small system you can just add 20%. you don't over fill that way.
***** If the system is full and you add 20% won't that be over full. I don't mean to be dense, I just don't understand.
Thanks again for teaching us.
Don
amtpdb1 not that critical, besides some of the old will hang up in the evap
***** Thanks
First time I have seen hoses like you are using on the vacuum pump?
Did you make those Jim?

How did u get that condensing unit to pull out like that .......the units i work on are difficult to pull out that far
I have an old Lennox unit with a mfg date of 1979. Actually, the serial number has been torn away but I dated it before it disappeared. I don't know if the compressor is original... it looks great, but the repair guy told me if it goes, it will be impossible to find a replacement compressor. Does that sound true? Thank you.
Why didn't you flow nitrogen well you were brazing?
did you change that filter drier when you put the bad compressor in? its a sweat and you seem to only put in flare, just wondering.
+James Mclaughlin yes
hey,,, i have that exact same cooler and my compressor went down the exact way,,, could you tell me what compressor i need to order
Nice job Jim
Harry Dickson thanks for commenting
Jim your knees are ancient...admit it!
Nice video enjoying it much maybe you need to have a younger technician for coming years. ty a lot
Micron gauge on the pump again. I was always told it's sensing what the pumps pulling. Check out True tech tools Jim
Kcarviper Its not so much of an issue on this size of system, can valve the pump off and see where the vacuum is at.
Kcarviper I didn't think it would matter so today I did a compressor change out, see video, I put two micron gauges on , one on the vaccum pump and one on the hot gas discharge port, the vacuum pump one read 155 microns and the hot gas port read 355 microns, clearly double. You were right, Thank You for bringing that up.
Hello Jim. I like your videos but I haven't see any activity of you.
If you read this message is there any way I can ask some questions.
I am new in hvac and is always a good practice to ask to hvac tech like you who have a long field experience.
Thank you Sr.
can someone enlightens me on how a single pipe torch runs a flame like that? what kind of torch is that and what gas used?
its a turbo torch. Air acetylene
what are u using as a torch?
nice work. How many employees do you have?
All Hours Maintenance just me
Wow. I live in Columbus. One day I will have to come up there and get schooled.
All Hours Maintenance My son Sam and his wife moved to Reynoldsburg
One of my complexes is right next to Reynoldsburg. The Ridge at Taylor Station. I worked at Indian Creek Apartments in Reynoldsburg for 3 years before the property sold last year. we were rated number one on apartmentratings.com. Now I roam all around Columbus. HVAC and Electical issues other guys cant figure out. Small world. I am learning a lot from your videos.
i think some of that beer should off being reclaimed ; )
I have debated with myself on whether or not to include low and high pressure protection to new compressor installations. It will save a compressor and a lot of cost and inconvenience for the customer in the long run...... whether they realize it or not. I will tell them first, and I'm sure most of them will balk at the idea. I will inform them of the reasons, and if they still want to say no, then the next repair will more than pay for the preventative action that could have been taken. That and regular maintenance. Probably won't go for that either. The old saying: You cut your nose off and spite your face will probably be true on this.
224psi discharge for r134, seem to be too high?
better than college degree on line...1100 for 4 hrs
Erik Cable thanks for commenting
that's another reason i change whole condensing unit--
Jim Jim Jim, what can I say? First I would like to say I have watched quite a few more of your vidz and you seem like a very competent tradesman. However your fixation with leak lock and thread tape seems to once again get in the way of an otherwise very educational posting. Here we see you putting goop on the suction service valve inlet thread on the compressor, why, why, why? In this case the white nylon O ring act as both the seal and as a spring washer preventing the rather large nut from loosening. I have somewhat became a fan of your videos captivated by your methodical procedures. Its just a shame you can't take my constructive criticism and learn from it.
+Ian Bartholomew Ian, your ranting about my use of leak lock is making me want to make a video dedicated to you, I'm going to get four tubes of leak lock and slather it on everything, it's going to be dripping everywhere :) peace out cub scout
Doing, not talk so much! Please.
