Thank you for the a/c power lesson. And thank you for reading the comments and acknowledging them. I have an exhaust fan at work that is smoking. It's a big one, blades are at least 5 feet diameter. When the Hvac guys come in I want to watch them diag it. We have 480 3 phase so I watch and learn before I touch. Not taking any chances. I am the maintenance supervisor for the 1.5 million square foot warehouse. I love watching your videos and soaking up the info. I've learned so much since I started watching about a month ago. When I get paid I'll order some merchandise I promise.
I got another one to add to this. The motor burned up from a single phase event and they found that the bearings are bad on the shaft. Someone installed small hoses to grease the bearings so you would not have to take the whole thing apart to get to them. The fittings were outside the unit. Just walk up and grease away. Well someone didn't tighten the hose good enough and the grease never made it to the bearings. The problem is you cant see the other side of the fittings. The whole unit has to come apart to get to it. There are 15 units that I cant see if they are getting greased enough. My scissor lift is maxed out just to the roof. I got a nice mess to figure out. Lol
In the restaurant industry, generally if you tell a manager about issues with a system, it will usually never get to the person that needs to hear what is needed or what repairs are needed upcoming. Often the next time you are there that person no longer works there. You always need to find a person above them if you can, and even that has a small percentage of success. I used to make vendors leave a log in the office with a synopsis of repairs made, or recommendations. Many times I went back and a new face was there, I said look in your file cabinet under Repairs. They would say holy shit this is great. Put the logo back centered on the ball cap as it belongs, I have no clue who in their right mind decided to do this on every cap, but it was originally because on camera interviews are off to one side, and with the sponsors logo off to one side it shows on camera better. And quit with the "merch" Merchandise!
Trick that usually works when putting a switch back into the box is pull and twist two times (if there is enough length of wire) and then push in and untwist once.
I appreciate that you take the time explaining things in depth. It’s helpful for those of us who aren’t in the trade but want to learn. Thank you for the videos, keep it up!
Your videos make me wonder what took me so long to find them. Love watching right until the very end without any interruptions, just enjoy soaking everything up.
"Big Picture" 100% of the time, when repairing anything mechanical. I don't work in HVAC, I fix more IT related machines. But there's still...always a reason. Granted, in my field that "reason" can often be a "user," the methodology of big picture diagnosis still definitely applies. As always, excellent advice.
You seem to change a lot of those single pole triple throw switches..... why not use a line throw handle disconnect? Seems like it would stand up better to the application? Great work... Be safe
Do you put lockouts on the breaker downstairs to stop some &@!?)£ from killing you while your up top changing the switch out. ? Love the channel stay safe
Lol “busted”. Good one, while heavy commercial and industrial would definitely require that, light commercial does not because there is usually no on site safety inspector to fine your company for not following OSHA protocols. But it is definitely a good practice.
6:53 I'm watching this video and the Flyers game at the same time and said to myself "where the hell did he get an insulated torque phillips screwdriver??" LOL!
Makes me glad the only frustration I deal with are 3-way switches in my old house built in the late '30's lol. I have to deal with the old fabric and wax sheathing that crumbles and that aluminized copper
Hi Chris, Why don't managers do a walk around on the equipment once or twice a month? It seems obvious to us, but it's not general human nature. It's like opening the hood of your vehicle when putting in gas and having a quick look at things. Does not happen, that's often costly. But, it's like that. We know why but lets end that thought here. You did a great job with the fault finding there, that is good quality and safe work being done there. Keep it up, Kind regards to all, South Africa
100% agree with your big picture philosophy. Whenever I get called to fix electrical I always want to know what caused the failure. I had to replace a breaker that wouldn’t reset and ended up finding a length of burnt wire running along two outlets. Overloaded circuit and a short to ground as a result.
as a hood cleaner. you should be cleaning the whole thing. when my team cleans the hood we clean every thing that deals with it. if it has belt we check that too.
I've asked myself quite often already, watching your videos, why put those switches on the fan chassis at all, instead of the frame or in a central switch box where the cables run down to the kitchen/breaker panel.. somewhere that doesn't vibrate. I'm also wondering why those fans generally don't seem to have any sort of roof or cover on them so it doesn't rain directly in to the motor or belt assembly all the time. I'm not in HVAC tech, I'm just a regular engineer, and the way these fans are designed just screams "high maintenance". Is this some job security thing that's going on?
I was just thinking when u turned the fan off and on with the safety switch: If on VFD you should never do that with a switch placed after the VFD because the start current might then damage it. If VFD was bypassed then I get why you could operate it like that. Otherwise u would have needed to to it from the VFD to avoid blowing that.
Why would the side of the case be dented like that? Is it possible that during high winds some debris smacked into it? Or you can open the hinge too far and smash that side onto the ground?
Why is there smoke in the kitchen? Probably because somebody's burning something! LOL I cringed pretty hard when I saw the motor's vents all clogged up. That poor thing was choking! Good practice is to simply replace a switch that feels odd. Even if the contacts ohm out fine, if the action is crap, it's gonna fail sooner or later. In the video it looks like part of the plastic toggle of the switch has seen some heat lately, that circuit breaker certainly saved the day.
I think that technically, with those TEFC motors, cooling air does not flow through the motor - only over it. "hasn't been running in a while.." NICE ONE! Sometimes we just have to suck it up. Long gone are they days of blowing out fins and coils with cheap R-12
Oh man you brought back some memories with that. Yup we used 22 just to blow the dust off our shoes, lmao. Crazy how things have changed so dramatically and they are still cutting refrigerants left and right. Soon we will be left with only water as a refrigerant, lol.
We had a customer with a similar situation and they had some previous tech wire it direct and took the switch out! I told them that was unsafe and violated code ! I was told it works don't try to fix something that is working! Unfortunately the customer was wrong but you can't argue with them! What to do?
The previous tech/company would be held responsible if something happened, unless you touch it. Then you own it. That's my understanding of the way it goes with insurance. CYA with documentation in big bold red ink! That will help you from being held responsible.
It’s because the fan is not belt turned so the motor shakes because it’s in the middle or look how the exit plate is bent that can be a problem be cuz is all the other exit plate there fine and not bent so that’s probably why the side has more playing than the other side so the motor wants to shake the over way away from the bent side
just a thought about the VFD being bypassed, have you guys run into VFD only motors? just wondering what sort of issues that will come from bypassing the VFD on those, especially after the warning label has come off.
I'm not sure how you would make a VFD-"only" motor. The VFD is just varying the frequency to the motor, but is still supplying 3-phase. Now, a motor specifically designed for use with a VFD, yes. But that is just designed to not get hot when run at high frequencies and with a crappy sine wave shape. Unless the motor minimum frequency is higher than 60Hz and it runs on the line voltage, I don't see there should be a problem running it directly from the line.
??? I've specified "Inverter Rated" motors, which are designed to better survive low speed operation on a VFD, and I have specified VFDs instead of soft-starter on *big* (100 hp +) motors for better electrical characteristics - the sparkies tell me that they cause less "ringing", and are less of a problem for demand management - but I have not read any motor specification where a motor absolutely must be run by a VFD instead of a starter - especially not for these
@@chemech i have no idea why its vfd only. But they come with a warning on them not to connect them to mains. No idea why or what would happen if you did.
I noticed the fan was pretty beat up too, was the cover missing off the motor housing too, or did you remove it before starting filming. Talking about the torquing up of the connections, another channel I subscribe to @ArtisamElectrics, recently showed a video of a fairly serious house fire caused by a loose electric shower breaker connection in the consumer unit.
I have my doubts that vibration is going to cause a switch failure. I'm pretty sure, UL tests that sorta thing when certifying commerical/industrial products like this.
If the vibration causes the contacts to create micro arcs then it will cause the contacts to wear faster. Even if no arcs and the brushes are vibrating then it will wear faster. Also, it was a vfd driven and most of those do not like to be switched between the motor and the vfd. Vfd's create higher voltages which might wear the switch faster. Should be a vfd input switch to turn it off and then a switch or disconnect to lockout power if working on it.
Your “pretty sure” means you do not know for a fact all while talking to a licensed mechanical contractor that requires at a minimum 4 years of school and field training, lmao. Vibration is a common cause of system failures whether electrical or mechanical in the HVACR field. It breaks loose solder points, causes bearing failure, and creates arc points from loosening connections.
Im quite certain that's a die cast metal terminal box, specially being on a roof in 120*+ weather and exhaust fan. Plastic conduit box would not likely meet code and would only last a month in those harsh conditions.
@@mrbyamile6973 I guess die cast aluminium could be possible? I'm an electrician in Europe and we rarely use those kind, but the color almost looked plastic to me!
@@JantjeVloet In the US metal conduit is still very common and as I suggested likely required by NEC (National Electric Code) for us on most commercial applications due to flammability. Even flame retarded plastics produce nasty glasses when heated. I'm not sure if its cast aluminum (aluminium depending on where you live) as the components seem heavier than aluminum. Whatever they are made of they are somewhat corrosion resistant but not real heavy duty. Feels like what old antique cast material model cars were made from in the 50s. They are painted grey with a thick powder coat like paint and look similar to the grey plastic conduit. I tried saving money and ran a bunch of plastic conduit in a greenhouse I built for my wife. It got hot enough to turn the conduit runs into spaghetti noodles, even warped the junction boxes :(
it's hard for most people to over-torque electrical connections, most often everything isn't tight enough. I'd be the fella that's at the limits of the devices, but had things come loose over the years and ruin my/others day/s.
The worse alternative to too much wire in a junction box is too little - you can always trim back excess, but you cannot cut the wires longer. Fortunately, you seem to be working with multi-strand connection wire, which remains flexible longer than solid conductor wire, where age hardening can be a real problem... ask me how I know... As for the gunk on that motor, that was just sad and disgusting at the same time. One thing that I'm seeing with those kitchen exhaust fans is that they don't seem to have any serious grease trap or filter in the ducts... makes life even harder for the fans, and the service techs...
Why not mount the switch where it doesn't vibrate? Like on the lower portion where the other box was located? Too low to the roof? If you want to run a vfd at 100%all the time then it wastes energy so cheaper to bypass. I'm sure they don't need it at 100%all the time though. Vfd are also good for phase loss protection.
So way you use so crapy switches? Use some dust and waterprove switch in germany by standart IP86. You replaced the swich anyway... labor expanse are much higher than the the 1$ more fore a better swich.

Maan that motor is just _vibing_
you can actually see it like wobbling softly but its because it vibrating so fast that the camara can't pick it up (at 10:07)

Carrying a handful of switchbox extension housings would make life easier.
