THIS WAS A TOTALLY UNNECESSARY SERVICE CALL

This service call could have been prevented but instead the customer chose to skip the preventive maintenance and the result was the murder of this compressor.

My day job is computer security and these types of failures remind me a lot of an unfortunately common attitude I've seen over the last ten years, where clients just want a checkbox exercise that says someone looked at it and aren't interested in investing any time or money into upfront preventative work. The irony is that they always end up spending more down the line because they have to go back and jerry-rig fixes and spend way more time and money fighting avoidable problems. Different industry, same deal.

[@JV-pu8kx]

Just about every industry experiences this. Automotive mechanics. Plumbers. Electricians. Healthcare.

[@Laurelinad]

@@JV-pu8kx yeah. to the point that even the workers got that mentality ... "it's for a customer only, so i can slack off" and those were the people that should teach me stuff (carpentry apprentice in germany at the time) and i learned something: not like this :D

[@TitaniumTurbine]

I actually work in a similar IT industry where account security and permissions issues are getting completely ignored. It’s not just customer data at play here, there’s records bound by law to be safeguarded. It’s a super f*cked up situation. We have the man hours to handle it but management doesn’t understand nor care about it. They have no experience with system/user security and their concept seems to be “well no one has told us it’s been breached, so we’re good right?”. WTF. All I can do is keep reporting my concerns in detail to maintain a paper trail showing I’m aware and not neglecting the obvious issues.

[@user-lm9gs5vt1q]

​​@@TitaniumTurbine I have played the CYA paper trail game as well! I worked for Centurylink and was in a position that required Secret Squirrel clearance from Department of Defense. At first, our quality of service was way higher than our normal service delivery. But as mergers happened due to economy and downsizing, it seemed that those bad management decisions creeped across the line. I left the company and I do NOT miss it. I went into business for myself and I can dictate the quality of service we provide. I don 't answer to ridiculous shareholder expectations. The result has been incredibly good feedback from customers who provide positive feedback. Direct communications allows me to hear their expectations and then to exceed them whenever possible. Obviously, there are times where we have to deal with product limitations but, our labor can be top notch. No regrets.

Regarding that case heater, it's purely resistive, so you can just do P=IV so 40W / 240V = 0.166A, then R=V/I, so 240V / 0.166A = 1440Ω, which means your resistance reading was spot on.

[@dman8016]

Thought of that as well. Then thought we never really do those equations in the field but actually could be useful

[@moteuteu]

The firmware in the controller really should have considered the temp sensor faulty given the value it was reading. It could have gone into lockout and thrown a code and perhaps saved the compressor.

It's annoying when lack of maintenance becomes an emergency on the weekend. It's like all that money you "saved" not doing a quarterly pm just got blown up with emergency service and parts that would probably still be fine if the sensor was noticed during a PM

[@JFirn86Q]

To know what resistance the belly band heater should be, it said 40 watts at 240v. It is a purely resistance device basically: P=I*V, or I=P/V = 40w/240v = rated current (i) would be 0.166A. Ohm's law R = V/I = 240v/0.166amps = 1.445 kOhms. That is exactly what you measured with your meter for resistance, so it's good electrically. If you were checking amps draw, need to remember you are at 208v at that location, so I = V/R = 208v/1.445 kOhms = 0.144 amps. (which is also exactly what you measured at 0.28 amps with 2 wraps of wire)

Your video timing is always divine. Just had a compressor leaking from a rust spot in its head at the suction line. Didn’t realize that was an indication of flood back. Replacing the compressor this afternoon. I like to think I would have found if it was flooding back but now I’ll DEFINITELY put it on the radar. Thanks for another great lesson Chris!!!

[@aaronbrandenburg2441]

Hey at least it helped or potentially help someone I'm sure that this video will help someone down the road. Not a technician but this stuff does help me with things and knowing more about troubleshooting and much more and it's just interesting how things can go and what you might learn even if it's not your field you're still able to learn from different aspects of things. I've seen a few bad compressor us on Old frigerators. Close to where I live they have mini splits and the other units of the larger condenser outdoor units all heat pumps as well. Can't think of a brand name but apparently these are known to have problems I've heard about a lot of these bite the dust. There's one even if you're quite for a way it sounds like a heavy duty vehicle of some sort or even some types of heavy equipment. That compressor is clearly on the way out the sound is like the sound of surging and it sounds like is struggling so hard it sounds like it might go anytime. I was actually one time going for a walk one of the units had blown in Sterling bejeebers out of me! Pretty sure what it was the electrical connection at the compressor letgo possibly electrical fault. Definitely would startle anyone. I think there was one of those doing something similar in one the videos as well! There was a huge record clearly something let loose! She let go good I can do you that Where are used to live even though an apartment maintenance text there was having problems with the unit all the time. They realized I knew what I was doing was able to help make sure that everything was running right. Was an R12 system unfortunately not only that it was old and well decrepit the outdoor unit was basically completely shot! Leaking refrigerant for sure topped up several times! And I'd heard they had had plenty of problems before I moved in. They actually made it so that I can easily get to the Lauren set by just moving some insulation to just check to see if it's operating properly. When they realize I was able to check. Said we need to have service calls as much for maintenance. Also generally they would have maintenance change filters however if they realize people could take care of this for themselves would just either have filters available at the office or they doing something else bringing extra the people extra filters. First thing I did was have a digital thermostat installed it was so badly installed the Old Mercury switch one it was so out of level there is no way to even have an accurate thermostat by any means. The melting was off by several degrees as well as the Box wasn't even leveling the first place doesn't help that you can't actually put that one level within the adjustment range! What were they thinking putting that in. Not only that later on bypassed the float for the condensate drain. The system was never properly installed one the maintenance text actually read it that is what actually works properly or at least as much as it could. Helped a little but not much the bottom panel that was meant to be removed in that top of insulation was still in place. Originally a filter within the utility closet door. It's so much restriction the way it was installed was pulling air into a small gap between a board holding up the indoor unit. There was just a small gap between that and the door. So much so that it would pull the door shut just because of the airflow. Even though plenty of room in the door vent return air goes to show how badly things were done. It did make quite a bit of difference but not enough to overcome the inadequacies of the install and the conditions of the rest of the HVAC system. It was just pitiful and it was a slum there's well unfortunately. Almost everything was online listed as Aslam and slumlord and just about everything you can think of wrong every one of the boxes checkmark checkmark checkmark rinse repeat

[@arska6383]

That sharp and metallic sound from the compressor told me immediately that there is some significant play somewhere in there. I was somehow expecting to the compressor to have a failed crank bearing or even a bent connecting rod after trying to compress some stuff that is not compressible, but apparently the reed gave up first and it was just the top end of the connecting rod which got busted. The piston with wrist pin play might have done some extra hammering against the valve plate after the initial event. I am learning new things from your videos. To me this seemed first like bearings coming to a seize and braking the compressor motor that way but like you said it was more like a hydrolock event with the liquid refrigerant.

[@rustynail2210]

Great autopsy! I'm more of a car guy (hobbyist anyway, retail by day, wanting to get into HVACR), but some of the engine knowledge carries over to a piston compressor.

After watching you pull your tools and comp onto the roof I have one comment to make...I used to do the same thing ( retired now after 45 years ) and ended up with a hernia and bowel issues that had to be operated on.

Being cheap with pricy things causes long term issues. I with some friends replaced a well pump we had a issue with wire connectors that's not suitable for 240 volts.

Definitely heard that compressor slow down briefly on the phone microphone. Strange problem for a good Copeland, I figured you would find the cause of the failure. Good you caught it in time before it burnt up and contaminated the whole system. Excellent showing the disassembled compressor. Definitely liquid coming back and lack of lubrication killed that thing. Nice quality video. 👍🏻

[@wsdylan8123]

i think i saw 33A draw when it sounded like it was losing voltage

[@gordonrockafellow1211]

The black oil is from the aluminum powder from the rod end and wrist pin journals. The piston and rod failure is due to the broken discharge reed valve. The broken valve allows constant discharge pressure on top of the piston, this constant pressure doesn't allow oil into the top of the piston pin journal and bottom of the rod journal. Normally pressure is relived on the top of the piston on down stroke and oil circulates around the wrist pin. This failure occurs over several months of a lack of lubrication I have seen as much as an 1" of wear between the rod and piston on larger compressors.

Chris, I'm a senior long term tech (got my EPA in 04) with failure analysis background from my Navy ET days. I'm primarily a Refrigeration guy, but am also fairly good with light commercial HVAC up to about 25 tons. I'm curious why you use R407C vs R422D for R22 replacement retrofits. I'm extremely impressed with your teaching style as it's very similar to mine. I operate on the theory that the details are absolutely critical in training because it gives folks more places to tir the information into a coherent and useful whole. Kudos.

[@keldon_champion]

I had a KE2 with a bad pressure transducer causing it to open the expansion valve and flood on a Saturday evening, it was the same system style duel evaporator system as the system you where working on (also a beer walk in). I didn't have the part on hand so I just pulled the fuse out of the KE2 and ran the system as a single evaporator until monday when united refrigeration opened, they are a well trained customer so they don't leave doors open and I knew it would be fine.

Trick to test heaters: V^2/R=W so on that belly band heater: you read the 265V section, but either works. (265V*265V)/1465 ohms read on meter=47.9W. Or: (240V*240V)/40W = 1440 ohms nominal should be on the meter.

[@ejonesss]

it looks like a single phase compressor was used instead of 3 phase a single phase would have common, start and run markings a 3 phase would use a, b, c or L1, L2 and L3. a single phase may work for a little while because large compressors like that dont have overload protectors that are removable they have the protectors internally and the protector usually opens the common connection. in single phase substitute the 3 phase may get the compressor to start and run for a short while then it gets hot and the thermal protector opens and now the connection is going through the start/run windings and may still run but will bog down. that is my theory.

One thing that puzzles me is, @14m when the compressor was starting with pressure on the side it needs to draw from, and no back pressure on the side it needs to push in to- why does the amp draw start high then drop? Seems to me that the compressor could spin for fun till it was asked more and more to push up hill , then draw current... or do these have an ability somehow to get more done when the demand is low. But then to actually need more power than when they are seeing the full psi? It's hard to comprehend what is going on.
