No problems with the messed up audio. That roof equipment dub was soo good I didn't notice it was a dub at first, until you you started poking with the meter.
This is one of the best "my audio broke so I need to do a voiceover"'s I've ever seen. It's almost seamless and if this was my first time watching I probably wouldn't even notice! Great job on that, great recovery. EDIT: I have to admit, this feels like a commentary version and it gives "more insight" since you're voicing it after reviewing it. Acknowledging it's a voiceover and not pretending that it's not is the best way to do a voiceover
This big picture idea is what all service techs in any industry should do. I own a irrigation repair company in Texas. I make all my techs watch a few of your videos. Totally different industry but same process. Don't just fix the issue find and fix the cause as well. As I tell my techs. I want return customers. But I NEVER want to re fix a previous repair.
I'm just a regular homeowner and tinkerer and it's thanks to videos like yours that I've been able to track down and repair every problem that's come up with our 27 year old system. I enjoy watching you work through your process as it parallels my industry perfectly. Thanks for doing what you do!
Your mistake is a good learning tool ! You always need to use a trouble shooting precedure! Start from the beginning at the disconnect and take it from there! That will save much time and effort! Like you said after you fix the problem it's equally important to find and fix the cause of the problem to begin with so it doesn't repeat it's self! Excellent video! Remember your mistakes are an important learning tool That's why it's imperative that you share them! No one should ever feel bad about making mistakes because the only one that doesn't make mistakes is the one who is not doing anything!
This was a great demonstration of a big picture diagnosis. I wouldn’t beat yourself too much over the hasty breaker reset, it’s not like you had your disconnect closed and were chancing everything like a LOT of people do. Hell I’ve seen techs reset breakers 3-4 times till equipment burns! SMH.
At the end of the video when you doing the run down of everything I noticed the old school charging canister in the back perfect for small charges that are ounces love your videos I been in the field 15 years and I always learn something I could do better from watching you keep it up
Nice to see you're human Chris. You definitely come across as a supertech at times so it's good to see a slip up every now and then to see it happens to the best of us. Great video.
The voice over with fan noise is actually really good. Of course, I like hearing you explain it as it happens. That's strange how that wire burned up mid-run.
You talk about the big picture analysis. In the IT world where I work, when we have any major failure, you have to do what is known as an After Action Report (AAR). And one part of that is a root cause analysis. It can help head off other failures. If you can replace something before it completely fails then you avoid data loss.
The reason why those brackets break after you replace them is because you are not replacing them with the OEM condenser fan motor which is a 10254004 Russell yellow motor. The 9721 are heavier than those yellow motors. And I remember in of your live videos, you keep stressing on using OEM parts :D
I had to do a maintenance on a residential split system for this condo. They had the roof replaced a month before hand. I step on the roof and my body had this small tingling feeling, but i completely ignored it. Went to go to take the panel off of the CU, and i could hear what sounded like static between my drill bit and the screw. Instead of removing the screw, i went ahead and slapped the unit really quickly and got this horrible static shock. I figured it wouldnt do it again, so i just slapped the unit again to make sure. Got another horrible shock. I touched another CU by the unit, got shocked. Touched a CU on a different part of the roof, got shocked. I figured the roofers ended up grounding a wire or something and left.
I'm betting that when the blue wire was originally pulled through the conduit between the 2 junction boxes, not enough care was taken and the blue wires insulation jacket was scrapped against one of the conduit bushings which left either a thin spot or a hole in the insulation and eventually, the wire was vibrated close enough to the conduit wall that it arced out and that's what blew the jacket apart. I've seen something similar with grounded extension cords when the insulation is scraped or nicked across the outer live wire and the middle ground wire. When the slit gets wide enough or something heavy compresses the cord enough at that spot, BANG goes the jacket and you now need to replace the fuse or reset the breaker after throwing the blown apart extension cord in the trash...
Nice work! On a unit with a defrost solenoid at receiver, sometimes its better to roll into a defrost to achieve pumpdown vs front seating a leaky service valve.
The shock you are getting is static. Dust moving through the plastic tube causes a build up of a static charge. If you look at 10:37 there’s a ton of dust that’s accumulated on the outside of the blower. Imagine how much was going through it when running! The wires happened to have the highest potential difference with your static charge. Many backpack leaf blowers have a wire that runs through length of the tube to help dissipate the static charge.
Randomness time! Google is upping their game! On an iPhone, whenever you scrub through the chapters the haptic engine feedback actually clicks when it lines up with a new chapter. I just now discovered this is a feature. :)
Good job. Man that thing was full of surprises when you just took the time to investigate. Great find on the unit beside your main unit call being the start of the problem.
It kinda looked like all three wires had some sort of crimping or damage at perhaps the place where the rubthrough occurred. I'm guessing that the sparky may have crunched the wires some way (like a loop in the wires while pulling them through, that tightens up against the edge of the conduit fitting) during the install. The blue wire crimp ended up pressed against the edge of the conduit. The vibration from the broken fan likely caused the rest of the problem.
Out of curiosity (don't take this as criticism), what does the US regulations say about filling an R22 system with a known leak? Because if you did that in Europe you would definitely loose your license, and probably get a heavy fine or even prison time, for breaking environmental laws.
It is not even close to that here. First they still sell it in stores to licensed people and it is readily available just expensive. There are regulations but they come with fines before prison and I have never heard of anyone going to prison for refrigerant regulation abuse in my 20+ years. Finally by our codes what he did is just fine as a tech because of his procedures of securing the leak and informing the customer. That puts the liability and responsibility of the leak in the owners hands and not the tech or the company. For the United States R-22 use will only stop when they run out of the current supply and not by environmental laws. Hope this helps.
US Regulations specifically do not apply to systems with charge under 50 lbs. So doesn't even apply here - let alone how loose rules are on leak rates, etc. once you get above 50lbs charge
Great job!! Watched till the end. I see that happen to I wonder if the wire was damaged when installed and didn’t get noticed and the vibration helped it along.
The vibration probably snapped due to the work hardening of the copper due to the vibrations then the current flow finished off the break. That is why you have stranded cable to cope with movement. I have seen single cores break due to vibration.
I hazard a guess that your blower is electric, and you use a cheater plug adapter to isolate the ground off the cord, the outdoor outlet ground is defective, and the high potential leg for the blower’s motor is slightly conductive to the housing. That’s why my washing machine motor uses a rubber belt.
I’m a jack of all trades and master of one... this is fascinating..it’s not my field but I’m very attracted to it because it looks like one of those jobs that can give a solid sense of accomplishment when done correctly. I’ve actually tried to get my son interested because out here in the north east, the weather can kill you if you don’t have a working HVAC system or at least a lot of wood...................😉
At 2:40 he’s got 7.5 volts on 2 of his phase checks with the breaker off. Something’s fucky for sure. Also, later we see the three phases out of balance. My uneducated, purely speculative guess is there is an open neutral somewhere and some voltage is finding its way to ground.
Good Video man. I'm very surprised that the box doesn't have any ice up issues with a 1x40 minutes defrost set up on time off. For the supermarkets we usually mark the receivers with colored tape and mark the date and rec level on it so on the next trip we can see what it was before. Not sure if that practice is used for smaller location.
Lol I never heard of or seen a receiver with tape on it in a supermarket . You can just look at the liquid level of the receiver by the analog gauge on the receiver or the rack controller if it is set up as a digital input
Nice big picture video Chris. Do you tone out the meter leads before checking for supply voltage? Just in case a meter test lead had failed and leads to a test indicating no voltage present when it is actually hot. I have never fallen victim to this but took it quite seriously when it was pointed out to me. Because it can prevent a fatal accident. Awesome show as always, like the style in which it's done. That's why we are here supporting the channel. Kind regards, Duncan, South Africa.
Thats ungrounded equipment/ improper test line to ground at that point and u would probably see around 10 Volts or more depending how hard the hit is ive seen it as high as 50 volts or other equipment is using the same ground / neutral and ur getting hit by the different potentials
why did you not use the solenoid to pump it down to check level ?.Also when checking refrigerant level i think you should check head psi and comp.amp load.thanks for sharing.
Hey Chris Thank you for your nice videos and you hard work to make these training videos, God bless you Why do you have to pump down to cheque the reciver tank? Is it to verify the charge if so how do you know if needs to charge the system or the charge is fine? Please answer my question. Thank you 🙏 😂❄️🔥❄️🔥👍👍❤️❤️👍💐🌺🌹🎊🌺💐🌹🎊🌺💐🌹you are a wonderful day
Everybody makes mistakes now and then. At least this was one that didn't hurt anything. Plus you had some pretty good direction on where to look after that, haha. Had to be a short somewhere
Maybe it was an artifact of the video but on the thermal imager pix the receiver appeared to have a level higher than the 3/4 level...having seen you do this several times before it just looked higher than the other times.
What are the fan motor brackets made of ??? It can't possibly be American made tempered steel or they wouldn't crack or warp even over 20 years. Maybe they are made out of ' Chineseium ' aka very inferior quality steel. I could fully understand if the motor brackets were rusted to hell but they aren't.
No problems with the messed up audio. That roof equipment dub was soo good I didn't notice it was a dub at first, until you you started poking with the meter.
It's the background noise that does it. Sounds like there's a rattling fan in the background that gives the feel of a roof. Sneaky.
This is one of the best "my audio broke so I need to do a voiceover"'s I've ever seen. It's almost seamless and if this was my first time watching I probably wouldn't even notice! Great job on that, great recovery.

Finally a Video from HVAC again,
Thursday evening saved.
"Big Picture Quote" is a genius concept. Period.
Your mistake is a good learning tool ! You always need to use a trouble shooting precedure! Start from the beginning at the disconnect and take it from there! That will save much time and effort! Like you said after you fix the problem it's equally important to find and fix the cause of the problem to begin with so it doesn't repeat it's self! Excellent video!

No one should ever feel bad about making mistakes because the only one that doesn't make mistakes is the one who is not doing anything!
I love this channel. ❤️I’ve been in the HVAC/R field since 1984 and I still learn something with every video!
This was a great demonstration of a big picture diagnosis. I wouldn’t beat yourself too much over the hasty breaker reset, it’s not like you had your disconnect closed and were chancing everything like a LOT of people do. Hell I’ve seen techs reset breakers 3-4 times till equipment burns! SMH.
One of your better videos yet! still my alltime favorite is the one where the customer cant open the front door becuase of underpressure
The narration and related editing was well done. It was actually nice to get the mistake pointed out like that!
Good job on the systemic approach. 👍🏻
I know nothing about coolers, but i stayed for all 26 minutes
At the end of the video when you doing the run down of everything I noticed the old school charging canister in the back perfect for small charges that are ounces love your videos I been in the field 15 years and I always learn something I could do better from watching you keep it up
Nice to see you're human Chris. You definitely come across as a supertech at times so it's good to see a slip up every now and then to see it happens to the best of us. Great video.
Staying for the end of the video is the best because of the summary in case we missed something in the video, especially for new guys like me.
There's nothing more valuable then learning from someone else's mistake. Thanks for sharing these videos.
Root cause analysis : RCA
Standard operating Procedure :SOP
Energy Evaluation Study : EES
As often as I can I push all 3 of these concepts.
The voice over with fan noise is actually really good. Of course, I like hearing you explain it as it happens. That's strange how that wire burned up mid-run.

Great customer service from Chris the majestic HVAC Tech !!
Good job in the overall.. “the whole picture diagnosis”! Thumbs up..
The reason why those brackets break after you replace them is because you are not replacing them with the OEM condenser fan motor which is a 10254004 Russell yellow motor. The 9721 are heavier than those yellow motors. And I remember in of your live videos, you keep stressing on using OEM parts :D
Chris I liked the voice you did when you said:are we in defrost? Noo.The sound you made!Nice one!
I had to do a maintenance on a residential split system for this condo. They had the roof replaced a month before hand. I step on the roof and my body had this small tingling feeling, but i completely ignored it.

I figured the roofers ended up grounding a wire or something and left.
As usual, great video. Thank you so much for including your “mistake” , definitely helps us keep the big picture in mind when doing anything.
I'm betting that when the blue wire was originally pulled through the conduit between the 2 junction boxes, not enough care was taken and the blue wires insulation jacket was scrapped against one of the conduit bushings which left either a thin spot or a hole in the insulation and eventually, the wire was vibrated close enough to the conduit wall that it arced out and that's what blew the jacket apart.

Its 1 47am I'm stoned and I'm forgetting what I'm watching the second I watch it basically but it's still a pretty dope video bruh
Nice work! On a unit with a defrost solenoid at receiver, sometimes its better to roll into a defrost to achieve pumpdown vs front seating a leaky service valve.
The shock you are getting is static. Dust moving through the plastic tube causes a build up of a static charge.

Many backpack leaf blowers have a wire that runs through length of the tube to help dissipate the static charge.
Knowledge is power i appreciate it more than you know
Great detective work. Thanks Chris.
Chris take care my friend, Getting shocks when the power is off means something else is going on, More than likely it's coming from another unit.
Randomness time!
Google is upping their game! On an iPhone, whenever you scrub through the chapters the haptic engine feedback actually clicks when it lines up with a new chapter. I just now discovered this is a feature. :)
Hey Chris loving the viper cleaner's they certainly do what it says on the bottle lol
one of your best vids, good job sniffing out the root cause of the rub thru. have a great holiday
Ya did good your videos are most informative people miss things sometimes cant be helped...
Good job. Man that thing was full of surprises when you just took the time to investigate. Great find on the unit beside your main unit call being the start of the problem.
Nice video thanks for the great video as today is my grandpa funeral today
Wonder if that intermittent shocking you were receiving was one of the other units with a semi grounded wire.
Or something 110V tied into the same circuit.
yeah, I would have wanted to find where that’s coming from. it’s not static.
It kinda looked like all three wires had some sort of crimping or damage at perhaps the place where the rubthrough occurred. I'm guessing that the sparky may have crunched the wires some way (like a loop in the wires while pulling them through, that tightens up against the edge of the conduit fitting) during the install.

So doesn't even apply here - let alone how loose rules are on leak rates, etc. once you get above 50lbs charge
It's good to be here in Asia. Everything goes. What's a recovery system? Everything is vented to the atmosphere here. 🙉🙈🙊
The old school ones with the copper gasket held it back pretty good
Great job!! Watched till the end.
I see that happen to I wonder if the wire was damaged when installed and didn’t get noticed and the vibration helped it along.
Chris move away from the disconnect when you turn them on. I understand that you dont have 600v in cali but still a 208v disconnect can explode.
Great work and thanks for the awesome content stay safe and take care
I have that exactly same thumb driver. Haven't seen any at Lowe's since Stanley bought the brand.
Thorough work. Good job.
Thanks for the video.
Bet sparky nicked the insulation for blue leg at install. Was your shocks from a bad ground in the dog house junction box?
The vibration probably snapped due to the work hardening of the copper due to the vibrations then the current flow finished off the break. That is why you have stranded cable to cope with movement. I have seen single cores break due to vibration.
You did a dang good job on the voice over
I have a backpack blower and when the humidity is at the right level, everything that is grounded gives me a shock.
I hazard a guess that your blower is electric, and you use a cheater plug adapter to isolate the ground off the cord, the outdoor outlet ground is defective, and the high potential leg for the blower’s motor is slightly conductive to the housing. That’s why my washing machine motor uses a rubber belt.
Have you ever tried using those magnetic strips for propane tanks to check receiver fluid levels?
Looking outside the box. Thats the key to great troubleshooting!
Tbh i liked the narration over the video
I’m a jack of all trades and master of one... this is fascinating..it’s not my field but I’m very attracted to it because it looks like one of those jobs that can give a solid sense of accomplishment when done correctly. I’ve actually tried to get my son interested because out here in the north east, the weather can kill you if you don’t have a working HVAC system or at least a lot of wood...................😉
Hey Chris you never followed up with the “shocking wire” while the power was off. What did you find was the cause of that?
I'm curious about that too
@@SebP85 guess he don’t wanna say....too secret spy stuff....😂
I'm surprised he didn't dig further into it. Big picture diagnosis would've included a random pulsing electrical shock lol
At 2:40 he’s got 7.5 volts on 2 of his phase checks with the breaker off. Something’s fucky for sure.
Also, later we see the three phases out of balance.
My uneducated, purely speculative guess is there is an open neutral somewhere and some voltage is finding its way to ground.
Great job and video like always
Good video Chris 👍
For the motor, is it because the dirt was built up around the shaft? Can one clean it and lubricate the bearings?
Good Video man. I'm very surprised that the box doesn't have any ice up issues with a 1x40 minutes defrost set up on time off. For the supermarkets we usually mark the receivers with colored tape and mark the date and rec level on it so on the next trip we can see what it was before. Not sure if that practice is used for smaller location.
Lol I never heard of or seen a receiver with tape on it in a supermarket . You can just look at the liquid level of the receiver by the analog gauge on the receiver or the rack controller if it is set up as a digital input
i was enjoying the dub so much that i almost was sad that it suddenly ended lmao
Great video. Wearing my hoidie in Philly. Real nice n warm 👍👍
Do you heat the receiver tank?
How do you heat It, do you use heat electric gun? 🙏🙏🙏🙏🙏
Cool video. Thank you.
Root cause analysis (the big picture) - the basis for any successful diagnostic/repair!
Good catch 🏴
Another great video thank you for sharing
Nice big picture video Chris.
Do you tone out the meter leads before checking for supply voltage?
Just in case a meter test lead had failed and leads to a test indicating no voltage present when it is actually hot.

Cool find... Anything happens....
if it pisses out its leaking! great analogy lol
Great video as always.
Another great video 👍👍😘
I would like you show us all the main tools and where we can buy them, that's will help to buy more professional tools and equipments. Thanks
Vibration is more likely the cause, depending on the type of conduit.
How do you like the fieldpiece bluetooth gages? I have the Testo's . As for the headmaster throw a bucket of ice water into the condenser.
Thats ungrounded equipment/ improper test line to ground at that point and u would probably see around 10
Volts or more depending how hard the hit is ive seen it as high as 50 volts or other equipment is using the same ground / neutral and ur getting hit by the different potentials
The shock could have been caused by dust blowing against something. Maybe building up a charge?
Looks like a rub thru on the wire. Agreed vibration probably.
Good voiceover! Keep up the good job!
Do you have a video showing your roof top service tool bag set up?
You are awesome man, I love the work keep going
A master has made more mistakes than a loser has made attempts.
That wire could have had a kink or bad spot from the wire factory. I had a roll of tstat cable that had a break in the yellow
Dont worry i have taken out a whole supermarket those one are very rare 👍
why did you not use the solenoid to pump it down to check level ?.Also when checking refrigerant level i think you should check head psi and comp.amp load.thanks for sharing.
Hey Chris
Thank you for your nice videos and you hard work to make these training videos, God bless you
Why do you have to pump down to cheque the reciver tank?
Is it to verify the charge if so how do you know if needs to charge the system or the charge is fine?
Please answer my question.
Thank you 🙏 😂❄️🔥❄️🔥👍👍❤️❤️👍💐🌺🌹🎊🌺💐🌹🎊🌺💐🌹you are a wonderful day
Everybody makes mistakes now and then. At least this was one that didn't hurt anything. Plus you had some pretty good direction on where to look after that, haha. Had to be a short somewhere
Good vid !
Maybe it was an artifact of the video but on the thermal imager pix the receiver appeared to have a level higher than the 3/4 level...having seen you do this several times before it just looked higher than the other times.
no live audio for some of it? it was throwing me off for a bit there.
Ummm. First minute of video he explains that he had audio issues.
Hey Chris, Santa said he'd bring your merch to Europe eh !
He said he’d deliver to Australia too!
Santa ‘drop ships’ during pandemics.
He said Uganda too. Still waiting
one question why you did not wash the coil while the motor and bracket off
It’s probably a floating neutral in the building and that’s probably what cause the wire break down
What are you using for audio? It sounds like you're almost narrating over the entire video the audio is so good.
On your service valve on the receiver do you have brass collars that you can tighten up?
7 People don't understand how much work goes into dubbing over work you already recorded.
Ha ha yeah I've been dreading this video for the last few weeks.... thanks for watching bud!
Did you really play white noise for the first bit where it was voice over? It was kinda funny.
What are the fan motor brackets made of ??? It can't possibly be American made tempered steel or they wouldn't crack or warp even over 20 years. Maybe they are made out of ' Chineseium ' aka very inferior quality steel. I could fully understand if the motor brackets were rusted to hell but they aren't.
I was like oh wow this audio is so clear, wait a minute. I noticed a repeat in the roof noise and came to check the comments. Yep dubbed.
I tripped a main breaker once. I was looking for AC2, and it was marked A2. Haha whoops
