Hello sir, Just wanted to express gratitude for what your sharing here on RUclips. Been watching your videos since I started trade school last september, and youve definately helped me with understanding the basics for sure along with "The Bigger Picture". This video is a great example, ive watched it several times but still get thrown off trying to mentaly diagnose the system. So be edified and please continue with your valuable content here.
thanks for watching I'm gonna go live this evening 4/29/19 at 5PM (west coast time) to discuss my most recent uploads and answer questions from emails, the RUclips comments and the chat come on over and check it out . ruclips.net/user/HVACRVIDEOSlive
One thing I noticed is that Copeland compressor had the 404A sticker on the side, I never see that except on newer compressors, I'd have done a warranty check on that compressor, might've gotten lucky on it.
Yes get rid of those grasslins! The paragon I stock can do multiple times, 15 minute defrost. 9000 series. Looking at the model # of that compressor, it’s already been replaced. TXV has probly been bad for a while. New equipment $$$
@HVACR VIDEOS have you ever done residential work?? which is better? I'm gonna be starting in the industry soon and I am studying hard. I really think I'd enjoy the style of residential repair/install. But watching your videos of commercial refrigeration is so interesting and makes me wonder if I'd rather do that instead. Please help
Wire thieves will carry a live wire detector and cut off anything that isn't hot. I hope the electrician installed a live-loop if they re-connected the fans.
Might the suction line get hot because of the windings producing heat and no refrigerant cooling it? Indicating that it might have not been bypassing? Thank you for your videos!!!
For the CTOA, do you recommend 30 degrees over ambient or 20 degrees. Measure quick recommends 20 degrees. Also, if you have a longer line set would it be wiser to have a slight higher head pressure to help with the longer line set. Thanks in advance! I’m referencing walk-in coolers and freezers. I work on a lot of water cooled refer racks.
whats with the severe PCB burn mark next to the unidentified resistor that sits next to R2 ? - id like to take that PCB and evaluate, diagnose and repair it
Did you nitrogen blast the condensers through? In hot environments it's one of the first things I do. Even when they appear quite clear a lot can still come out. Enjoying the vids mate.
Scroll compressors cannot run in a vacuum so front seating the suction valve is a no go on a scroll. As far as the hermetically sealed pot compressors they dont really recommend it anymore, but I still do it. On a semi hermetic it is still a valid test to check the suction valve.

did you say only 95 degrees? In New York State when it is 95 degrees all hell breaks loose, 16 hour days everyday dealing with the break downs. Hot weather sucks
@@HVACRVIDEOS Your welcome and happy new years im dealing with a 2x2 foot cooler on wheels with a bad thermostat that is owned by boar's head and they keep throwing the same thermostat model back in
Planet of the Apes wiring job. Did you laugh or cry? I would think an inspector of some sort would have took an interest before. Wow the s*&t you see out there! You save people's butts! I even showed others the "winch pull" on the fan starters. The one guy was older electrician and said "could you send me that please?"

Never thought I would be Binge watching Service calls. You are amazing.
Thanks!
Holy hell! You just saved them over $10-20k in future equipment failure by finding that issue. That is excellent customer service.
I try ! Thanks for watching!
literally burst into laughter when you showed what was going on at the other end of the wires good stuff
yeah it was kinda funny
I’m 19 looking to get into HVAC industry and your videos really hype me into it. Very meticulous with the troubleshoot!
There's your problem lady!! NO PIXIES!!!!!!!!!!!!!!
Now that’s a service call. Damn bro, excellent troubleshooting procedures!!!!!
Thanks bud!

Excellent man you know what you are doing l am learning a lot grom your vedios
You're videos are awesome. Please keep them coming.
Great video! I enjoy watching and learning as you investigate equipment troubles. What a mess you have there!
Yeah that was definitely a cluster! Thanks for watching!
Great recap and explanations. Thank you.
Nice job buddy, it pays to persevere & check things out properly.
Thanks for watching!
Those units are working hard. Great video
Thanks for watching!

My thoughts too, more than likely the txv caused the original failure and went undiagnosed
Mega multiple offender supreme 👍👍
Nor-Cal Refrigeration & H.V.A.C that could be the next big item at Taco Bell
Nice video usually staff/management had no idea whats going on in their establishment hopefully they will fix all of that exhaust fan
I hope they will get it fixed too, thanks for watching

Just wondering why you would put system in vacuum with known leaky schraders.
Good way to do diagnosis work man.
Thanks bud!
No one where I live wants preventative maintenance on their units, and when they do call it’s in such poor condition
For the CTOA, do you recommend 30 degrees over ambient or 20 degrees. Measure quick recommends 20 degrees. Also, if you have a longer line set would it be wiser to have a slight higher head pressure to help with the longer line set. Thanks in advance!
I’m referencing walk-in coolers and freezers. I work on a lot of water cooled refer racks.
I always checked compression ratio and amperage on air conditioning equipment to consider valve damage in the past.
For that mechanical timer you could put it in a small dust proof enclosure to keep it from failing.

Done similar test like that good job sir
I'm wondering if they robbed the fan circuits for something else because the panel was full.?.?.
Yeah that's what they did, they have since pulled new power to the fans.
whats the vid where ya fix the fan
Interesting that Copeland dosnt recomend that efficiency test with front seating the suction Is that just for scroll compressors or all of them
Scroll compressors cannot run in a vacuum so front seating the suction valve is a no go on a scroll. As far as the hermetically sealed pot compressors they dont really recommend it anymore, but I still do it. On a semi hermetic it is still a valid test to check the suction valve.
HVACR VIDEOS yeah that was what I was wondering because Iv been testing semis like that for ever wanted to make sure, thanks brother
Great job 👍👍👍
Thanks bud!
Awesome the pumpdown is a secondary to confirm the pumping of the compressor....
thanks for watching bud!
HVACR VIDEOS no problem I got a channel not much but gonna see if I can upload some more
I'm pretty sure I subscribe to you channel but if not I will add you!
Love your videos. Keep it up
Thanks!
Another great vid my man 👍
Was that fuse plug leaking on top of rec.? Quite often they do.
No

What kind of leak detector do you use?
I use the Dtek select
Nice job!👍🏼🤙🏼
Thanks bud!
did you say only 95 degrees? In New York State when it is 95 degrees all hell breaks loose, 16 hour days everyday dealing with the break downs. Hot weather sucks
120 was our high so far this summer 100 is our average temp.
Great video
Thanks!
Wow at those fans!
Wow that’s crazy
What kind of leak tester that is you using
D-TEK SELECT
10:43 uhm... wow. What a nice surprise.
i work in a grocery store and ive been the one who finds the display freezer is over temp and end up emptying it
Thanks for watching bud!
@@HVACRVIDEOS Your welcome and happy new years im dealing with a 2x2 foot cooler on wheels with a bad thermostat that is owned by boar's head and they keep throwing the same thermostat model back in
Good stuff man
Thanks bud
I have not see a semi hermetic compressor on here I think mostly ac
Site glass is flashing, low amongst other things! Leaky one
yep!
*sight
cmon, don't be one of those guys that makes people think tradesmen are dumb
WOW!!!!!
Where are you that it's 120 degrees? Yikes!
Southern California, 120 was the high for the summer but 100 is the average!
The terminology has my head spinning. But thank you.
Do you have email that I can get in touch ?
Hvacrvideos@gmail.com
Copper thieves! Im shocked they didn't saw zaw those lines, prob. Worried about drawing attn. To them selves.
Why not remover the defrost time and wash out with soap and water and then blow dry with nitrogen?

That's what you call a multiple offender.
