You are one of the few people on this planet who are able to admit that they made a mistake. You took viewers feedback serious, corrected your mistake and reuploaded your video. Kudos for that!
Don't be so hard on yourself, Chris. Armchair generals, quarterbacks, and techs are always going to be right. In the heat of the moment when you're working, things can be misspoke. You're one of the best techs I've seen, and your ability to explain and train is impressive. This is coming from a 30-year installer/tech/manager/now owner. For what that's worth. Kudos to you for highlighting your mistake.
this year is my 40th year in the trade and I have learned some cool new tricks/techniques from your videos. you have some really good content. keep up the good work
One reason why I always suggest your videos to everyone is your honesty. You don't pretend to be perfect and leave mistakes there for others to see and also learn from.
5:00. Flame outs…..old school trick that usually works. Cold wet rag (I said old school), fold into square, place on the dome of the compressor….. try it!
Top Tier Craftsmen-ship. In the Phoenix area we always quote to replace cc heater, outdoor fan motor, Contactor and Drier. Excellent idea to replace the drier with an HH. Flawless! She sounded like she was purring like a kitten.
Takes a real man to admit a mistake and to make it right. We are all humans, and none of us are perfect in any shape or form. I appreciate your desire to put out the most correct information you can. Bravo Chris
I personally love rivnuts, fantastic for stripped holes for panels mounting things in sheet metal. I'm putting them in all the time. But not for something like a compressor. They should have welded a nut on the bottom, or something beefier. Also, it's big of you to admit it when you said something incorrectly. I don't watch your content because you're perfect, I watch it because you're a fantastic tech and even though I've been in this industry for a long time, you just have a way of explaining things that's easy to listen to and reaffirms my own knowledge. Keep it up Chris 👍
I wondered what has happened yesterday, i had a 30 minute old notification for it on my phone, but the video was privated. Nice to be able to watch it now
I've also hated rivnuts, one little truck I've found to get a bolt out of them is to use super glue on the nut, if you can access it. Little glue and carefully unbolt and you have a decent chance of unbolting the part. I like the concept of rivnuts, but in practice they just suck
I think you are right about refrigerant migrating back to the compressor and starting with a comp full of liquid. I recently went to a call for a self contained open produce cooler. Unit shut off on high head from a seized fan motor. I pushed the reset and it sounded like the compressor was going to expode. Anyhow, although the hp tripped the solenoid stayed energized and over the course of a few days the refrigerant migrated to the compressor causing the awful sounding recip comp.
@@HVACRVIDEOS yeah man, dropped out of highschool after taking my ged, and went to hvac school. your videos definitly help alot and show variety for what to expect on jobs.
@@andenmcleod7355 I'm currently a 16 and going to be doing dual enrollment this fall at my local community college. I've been apprenticing for about 4 months now and can't wait to learn more! It's definitely not an easy trade to learn but I'm excited for the future!
I admire your honesty, humility and dedication. Appreciate you sharing your experiences on the field with us. These videos are a good source for building our knowledge of hvac. Damn, how many of us are gonna cut open a compressor shell and investigate what caused the failure? These are the only times we see it.😅 Thanks again! Please keep em coming!
I appreciate the training videos you've been doing brother. On another note I sincerely appreciate a humble person. Much love bro. Stay humble and stay blessed.
Speaking of crankcase heaters, Emerson has recommended installation requirements in their technical bulletins for each compressor model. In general, where the weld seam goes down the length of the compressor, they suggest that the torque nut and bracket cover the weld, not the heating element itself. This is to prevent stretching of the element and also it's generally not a flat surface and there will be an air gap if the heating element were to cover it. The torque recommendations is 20-25 inch pounds. The crankcase heater shown in the video looks a tad bit high. Every compressor will be different, but for example the measurement could be 0.20" - 1.22" from the bottom of the base plate. There are crankcase protrusions seen towards the bottom of the body of the compressor. Some bulletins recommend above or below these protrusions depending on the compressor. The main point is that the clamping bracket should be placed over the weld and not necessary convenient for the install or servicing technician. Here's a video to explain it - th-cam.com/video/y3PsTyCN6aw/w-d-xo.html
Just to point out, the windings on all motors have an enamel coating to prevent shorts. The acids will soften the enamel and that will float in the system as a wax like substance. Also scrolls will normally separate a little when they experience over pressure from a liquid getting into the scroll. Depending on design it will either separate enough until there is room for the exhaust valve to allow it to pass or the internal valve opens. This design might be with that coupling does not allow the scrolls to separate with liquid slugging. Always a good video when you get a teardown of the compressors to see what happened.
Past 2 weeks been busy and tired but hopefully will be back on the live stream on Monday love your videos and try teaching others while trying to get them to watch your stuff on TH-cam. Thanks again for all your content
Compressor changeout I’d automatically replace the Crank Case Heater and Contactor.as well. I’ve also seen people replace Condener Fan Motors and not replacing Capacitors…. Doing so I my opinion is like putting old parts in a new Transmission.
I began sweeping a refrigeration shop and being a gofer to brilliant technicians there when I was 10 years old. They apprenticed me and when I got my driving license at 16, they gave me a service truck as I was at journeyman level by then. Nearly 50 years doing HVACR and was never without work. I'm now retired at nearly 61. Until I was 16, they paid me cash under the table so child labor laws weren't violated.🤣
If you're right and the failure of the crankcase heater broke the compressor, then perhaps the system should be redesigned slightly so the heater is part of the compressor start-up... By that I mean, during compressor start-up the heater is briefly turned on (if it's not cold enough to require it to be used) and if it won't turn on, then the contactor can't pull in to turn on the compressor motor... A better system (assuming this won't damage the compressor) is to simply wire the heater in series with the compressor motor so it turns on when the compressor does so if the heater has failed and can't turn on, then the motor circuit also can't turn on and the compressor can't undergo a flooded start due to cold conditions...
Great video, no criticism here just commenting... Those pieces can just break too, from wear or possibly a manufacturing defect or design flaw. Personally I think Scroll's are way more liquid resilient, especially versus a piston type compressor. I used to cut open all the failed scrolls I replaced and I'd say 90% of the time that same coupling piece is what broke. The pieces jammed the rotation (locked rotor), took out a winding (open/grounded winding), or the compressor was just free-spinning and not pumping anymore (low amp draw, no pressure change). I'd actually say its pretty uncommon to find a failed scroll where that piece wasn't broken, for me at least.
I was going to say it but you did. Not adding a liquid line port. Another side note where you mentioned about lines rubbing a dab of silicone in those areas work wonders on potential rub areas.
We all make mistakes Mate, in fact the one who never makes a mistake is the one who has never done anything. Don't worry about it, learn from it, and move on. Another great job done and great diagnostics.
7:00 i would have thought keep the 2 cut bolts as locating pins for the compressor. Not sure if it would much though so cutting them off isnt a bad thing.
Love your videos Chris- fyi youtube should have an editor where you can put in clip like the intro while keeping the video live... I haven't done it myself so idk the legitimacy, but may be worth a shot!
It sounds to me like it had just the wrong (or right) amount of flooding enot enough to be outright hydro locked but enough that if it started moving it would do real damage from the inertia
Hey bro..... Good videos, I enjoy them. Question: what kind of tip do you have on your oxy-acetylene setup? I can't seem to find something that spreads that nice for bigger pipe. Thanks.
The clever people learn by there mistakes !!! It's the people that make them day out day in 💯 But yes if this happens in the winter the refrigerant migrates to the coldest place which will be the compressor up on the roof where it needed the crankcase heater working 🥶
Hi Chris, long time viewer from Slovenia here, when you commented that you hoped that the compressor went bad due to single phase running I wonder why you don’t use 3 phase control relays to protect the units? The control relay detects presence and correct sequence of the phases and if you then use it as lock out signal so the unit does not start when there is a problem with input voltage.
Pretty sure he was referring to the contactor single phasing the compressor, not the supply losing a phase. To prevent this you would need phase monitors on the load side of each three phase contactor. And in this case, where cheap US manufactures use two pole contactors instead of three pole, the phase monitors would trip every time the contactor de-energized, since there is one phase that is always energized. But, I do agree and I don't understand why more US equipment does not have phase monitors to at least monitor the supply. I see phase monitors on just about every piece of three phase equipment from Asia and EU that I work on and almost never on US made equipment.
@@inothome probably right, in EU there is no way this kind of installation (one phase left energised) would be allowed, here all the phases must go through contactor and if present neutral too.
I've never had an issue with the 3/8 copper with the Navac tube expander I must be lucky..question on the metering device...have you ever ran across a unit that the metering device is not operating properly after a big job such as this?
My understanding is that it's not the refrigerant that does the damage, or rather: As the compressor sits in cooler climes refrigerant condenses in the oil. On first start up the drop in pressure inside the compressor causes the refrigerant to rapidly evaporate. This evaporation in the oil causes the oil to 'boil' as it sits at the bottom of the compressor. The level of the now 'boiling' oil rises (like water level in a kettle rises as it boils. ) Sufficiently to allow too much oil (more than normal and acceptable carry over) to be dragged into the suction inlet port and into the compression chamber. The excessive oil is trapped inside the compression chamber and as it wont compress, hence tries to bust its way out instead... Therefore its actually the oil that does the damage not the refrigerant although its the refrigerant that causes the oil to enter in the first place . Anyhoo thats my understanding..
I wonder if it was possible to know the old ham coupling was going bad - then again, putting in a new ham coupling might be more trouble than changing the compressor.
Not a HVAC person here but why couldn't the catch all be moved to a more serviceable location for replacement for next time. Does it have to be within X amount of a certain point?
Nice opened a scroll compressor to literally see what caused the failure. Cch a $20 part . How cold temperature wise does that part of the world get in the winter? I tell peoples that I know alot but I do not know everything. The HVAC&R tech that claims to know everything is a lier.
Chris, don't be so hard on yourself. It looks like you're eating you out in the re-edit. Everyone can make a mistake, but there is a few of them who learns from it. Get it up, man.
Sorry to be the bearer of bad news but, despite the re-edit, you've made the same mistake twice regarding the operation of the compressor in that you described the moving scroll as sliding back-and-forth when in reality it orbits within the fixed scroll to provide the compression. In fairness, though, you did say 'orbiting scroll' in the commentary at the end. Regarding flooded starts, it would be relatively simple for manufacturers to implement a sensor on the compressor to detect this condition and prevent the compressor starting in extreme circumstances. An extra port on the side of the compressor with a window for a optical sensor would be one method though there may also be electrical/electronic methods of achieving the the same thing, even going so far as measuring the liquid level within the compressor casing. As there are low oil level systems on compressors, why not a high level sensor?
@@inothome As there are already compressors with extra connections, both refrigerant and electrical, where the extra connections are not problematic I don't see a problem.

It sounds to me like it had just the wrong (or right) amount of flooding enot enough to be outright hydro locked but enough that if it started moving it would do real damage from the inertia
Why do some manufactures have ambient temperature switches for their crankcase heaters? Iv'e seen a lot of trane units use this design.

Great Video. Thank you for sharing. May I ask, Why's single phase Contactor use on this 3 phase power hvac unit ? I'm newbie ^_^
Cheap American made equipment saving money using two pole contactors instead of three pole contactors.

crankcase heaters are so underchecked during PM's. its very common that a 50 buck heater (or other part) causes a 15k repair.
