Plastic bags are a right menace - they'll wrap around fans, wheels, even outboard motors. Glad to see fewer of them these days over here. Nice rundown of the issues and fix, didn't just leave it at "bad motor, buy new". 👍🏻
Never seen a trash bag wrapped around a blade like that before. Have ran across balloons stuck to condensors and tripping on high head safety. Good stuff Chris !
Balloons are a menace sometimes
@@HVACRVIDEOS Cooks can be a menace too. 😁
Good thing you changed it. It was on its way out for sure
It really was on its way out, thanks for watching
I know it's not great for liability purposes...but I have replaced those motor bearings and used the motor as a spare or emergency or left on site as an emergency motor. They are fairly easy to replace. It did look like the rotor was grazing the stator bars slightly. Always enjoy your content Chris
new bearings and is good to go,it is nice to have motors when the parts house are closed,it feels great when you can get the product cool again.
You sound like a technician not a wreckniciain power to your brother
Thanks Bud
Just today i took apart a utilitech pro floor fan that was buzzing but the blades weren’t turning, motor was full of particle dust among other things from being used on the job painting and being used at home, Took apart the motor, put some 3 in 1 non detergent on the bearings, put the motor back together spun it by hand, reassembled the fan and its working like new! I completely understand the liability something like this could cause working for customers but for a fan that was in dads projects that will eventually be thrown out pile, i saved it, probably like the 5th or 6th fan i’ve done this to, though usually i do it when i notice the blade coming to a halt with no spin down when shutting off the fan. And not when it stops working entirely! Lol
On two occasions I’ve seen a snake wrapped up on the shaft of a residential condenser that caused the motor to stop spinning. Snakes have a unique smell when that happens lol. Great video!
Ouch
I feel sorry for the snake.☹️
Nicely done. Surprised the bag managed to fit through that tiny gap.
Had a call last week, Heatcraft freezer condensing unit with two condenser motors. Found 2 dead squirrels, one in each. Mmmmmm😮
FYI: opening music just a bit too loud. Chinese ball bearings are almost always crap so are the capacitors. Great channel Air over motors are better than air through unless it is indoors.
Oh the good old bag causing trouble! Great video brother!
If it isn't a bag it's dandelion seeds or nest building insects.
One man's bag, another man's bread. Get It, bread bag !! Lol, said nobody ever
Same thing happened to me a couple weeks ago haha I ended up having to pull the motor out to get all the plastic out
Great tips. Love how you gave a look over all their equipment while you were there and generated addtional work for the week by finding the low pressure on the kitchen A/C.
Another great big picture diagnosis.
Thanks
Crhis buenas tardes, otro gran video y nuevamente un gran diagnostico, es increíble ver cómo perjudican los equipos simples objetos que a diario vemos.
Saludos a todo tú equipo desde Coacalco estado de México.
Gracias- como es Coacalco Mexico este tiempo del ano ?
@@HVACRVIDEOS
En este tiempo es época de lluvias que apenas comienzan, pues se han atrasado, mas sin en cambio esta el clima con calor 32°C aproximadamente y para nosotros es mucho calor. Y no se compara con las temperaturas de tu zona.
Cme across a similar situation,was the only bag on the rooftop and I was like what ar the chances,we had to come back and replace the motor a few days later,
Got so hot that all the metal expanded when the motor starts to cool off thats when they fail,bearings start rubbing together.
Great job. I've seen multiple time plastic bag randomly came to the ac and walk in condenskr blade and motor burned the motors. I usually do 7-11 store some of them have gas station and people are remodeling the buildings or gas station and lots of plastic bags around their tools fly to the coil😅😅. Thank you Chris
Thanks for watching
It takes about 5 min to check low pressure switch,in case the switch is short cycling.2 cents.
Good work on this one chris
those bearings for the condenser motors are $13 ea from grainger 5U532 part number and or a 6201ZZ/12.7C3
Or you can pull them of out of a failed x13 motor,i am sure nobody has any of them laying around LOL.
Great video. Thank you for sharing. Have a nice weekend
Thanks, you as well
Wasn't that the walk in from some time ago where the master was icing up and the slave wasn't and it ended up that the valve on the slave wasn't opening? Looked familiar.
One Trashbag creates a big headache. I was surprised that motor even started back up considering how much bag he had eaten.
Great video
Thanks
Great videos! Learned a lot from your videos.Thanks for sharing!
Thanks for watching!
yeah, i remember this exact same thing happening to a very similar condensing unit in one of your older videos
Nine WI condenser units on ground floor, next to the dumpster grease pit in an extremely windy area.
Always my first stop walking in the building checking for bags blocking condensers.
Wow i love your videos dude. I’m really inspired with all your work. I’m in the middle of getting some tools.Can you please make a video on the type of stuff you use and any links.
I remember the same thing! There was once a trash bag wrapped on the blades of an outdoor condenser!
Great job Chris i use both oem and after market motors don't have a problem with either one. Just what ever is fastest.
I like your videos, Virtual job shadowing i love it
Glad you like them!
I was thinking it was going to be a frozen coil with a bag in it. I've seen that, but this also makes sense.
Great video, Chris. You packed a lot into it. It was good to also see a brief autopsy of the motor. Depending on the type of plastic and the temperature the motor reached it is conceivable that the plastic material actually melted in to the bearing.
Thats a good point
As an Electrical engineer specializing in motors- 100% good call on replacing the motor- I would have replaced even if no visible symptoms.
I’m surprised the rotor made contact with the stator.
I love your usual wiring, the 2 zip tie trick should be practiced by everyone, though I did notice the wires were quite taught. Not sure if it just wasn’t feasible to wire it differently, but if possible it would be nice to avoid.
Nice job 🙌👍👌🍀🙏🇭🇷
We had something quite similar happen to at one of our data centers. Big ol sheet of visqueen from neighboring construction got blown onto the roof and then sucked into the glycol units on the roof and took out a few fan motors. Fortunately the redundant string on the other side of the building wasn't hit or we would have been in the crap for real.
Great video chris, very nice repair, i really wonder who left plastic bags around the unit, be careful putting your hand in the fan shroud because those blades are like saws, i bet that motor is fried
I am sure that a change is coming to these fan motors over the next few years as the price of copper goes up. I expect we’ll see all electronic commutation motors with far less copper in the windings starting to appear. These will probably have all of the electronics and windings fully encapsulated as well. No more start or run capacitors. But will be a throw away item if anything goes wrong.
Thanks again Chris ❤
Was that another example of the mysterious Santa Ana winds?
Betting that was a bag from the filter installers. Especially if this is a not so uncommon thing.
Good point they do use bags and I bet that was from them!
I have seen the bags stuck to the condenser core but never sucked into the blades. I love watching to see what you run into to put as bits of info for me to pull if I see something similar. Did run into a recent issue with a AO smith water heater setup with two heaters in one room. Both had gone down and spent a few days figuring out what was going on. Ended up that the plug for one of the gas valves has a bridge rectifier inside and one of the diodes had died. Then the other heater had a problem where if the board got too hot it would start to pulse the relay for the gas valve. The interesting part was that it worked just fine most of the day until the evening when the sun started to hit the side of the building where the water heaters are kept. No AC inside the room and only heaters. Ended up calling factory since they were installed back in December and January. Both parts are covered under warranty.
Good catch, both of those issues sound troublesome to diagnose
@@HVACRVIDEOS The worst part was the plug made it seem like a bad gas valve. The temperature one I stumbled on with opening the door to the room and letting the heat out and it started to play nicer. Then circulated the hot air out and it stabilized.
A+
LOL I had a walk-in freezer go down, because of Saran wrap that the cooks used, was not secured and got sucked into the back side of the evaporator coil. blocking the air flow and causing the coil to ice up. What happens outside happens inside too 😁
Very true
Ever come across a family of pigeons? In NY I’ve had to evict many. The young ones look crazy
Most motors have a one time thermal fuse, so if it does pop the motor is done, you can put a new thermal fusion, but it's not worth it. The coils could also be damaged, and if it's an e. C I motor it could have blown up the moss thoughts
Wonder where the bags came from? I suppose they could have been blown up there. I could see that with one. But 2? And PREVENTATIVE maintenance prevents EMERGENCY maintenance. Usually at the worst of times and weather.
Yep. Plan for preventative maintenance, or the equipment will schedule maintenance for you.
@@mangamaster03 Usually at 10PM on a saturday night.
@@mangamaster03 Good point
A plastic bag sure beats having to clean pigeon/rat/snake jerky out of a fan!
Doesn't Big Clive join you on some of your HVAC overtime video streams?
Yes he does
@@HVACRVIDEOSwow. Glad to watch another steam with Big Clive
Are we going to see Solidstate contactors?
They are super expensive but would last hopefully way longer
There's a decent in-between option with the contactors that open only on neutral-phase like Copeland's 49M11-843. They last a long time and are under $60. But I don't believe they make a three-phase iteration.
You can get solid state relays already for 20-60$, the trouble is that they need more heat sinking and frequently fail closed. Ideally, you'd use a solid state relay to switch the load and a mechanical relay to provide a secondary disconnect that wouldn't open under load unless a malfunction occurs, which would provide a lot longer life.
Is this the place you replaced the indoor fans, and the control board, because the two boards weren't talking to each other? The video was a month or two back, I think.
No different location but it looks similar
@@HVACRVIDEOS ah ok. I remember the blue guards and the fact that the two machines weren't communicating, and you were annoyed by it at first. 🤣
I remember weird shit.

Motors need better thermal protection and a rpm hall effect sensor if it’s not spinning cut power
The simpler the better. If you want to put a hall effect sensor with the requisite electronics to cut out the motor you have ended up with an ECM motor. Overkill.
For electric motors, I've always had a hard time dealing with motors and their HP. I wish I could calculate what the true hp of a motor is, but I don't have the knowledge to accurately figure out that.
If the RPM is correct and the new motor is drawing within 50 to 100% of its rated current, then it's generally a good replacement. Having the new motor draw 75% its labeled current could be good target to aim for. Go below 50% current and the motor is inefficient, wasting some electricity. Go above 100% and the motor cooks itself, decreasing lifespan.
All that said, "electric motor" is a surprisingly broad category of devices, and things can get really weird, especially when you outside the realm of mass production. One day I read the index of the book "Electric Motors and Drive: Fundamentals, Types and Applications" and I realized how complicated electric motors can be. Seriously, go read the book preview. There are so many interesting and fun to say words that I didn't even know existed.
I think your 1st idea was best,the blade is too far from motor.2 cents.
67 thumbs up
You're lucky you're your own boss because if I was, I would tell you straight up.I am paying you to use 2 hands.Not one it's a safety thing
Weekend callout!!!!!! 🥹🥹🥹
👍👍👂👂👂👂🇿🇲
Wrong. You go only by the motor HP (power) and RPM rating. Remember, that the power rating is the mechanical output, not electrical input! The current draw depends on the exact voltage at the terminals, motor construction (power factor, efficiency, etc.). Only the mechanical output is relevant! One motor will for example do 1/3 horse with 2.7A, the other with 3A or whatever. Does not matter, it is just the motor construction (efficiency, power factor, ...) You only check the amp draw for overload. You select motor based on required RPM and HP (power) output. Current is irrelevant for motor selection. It is perfectly fine that different motors take different current to produce the same amount of work.
Wow actually first
Unbelievable how lazy people have gotten. There was so many plastic bags up there that someone obviously left for you to clean up. No way the wind could’ve blown that many bags up there. And even if somehow the wind did, it doesn’t change that somebody didn’t take the extra 3 seconds to properly dispose of those bags. It’s not hard to clean up after working on something. You’ve clearly demonstrated that it’s extremely easy and takes only seconds to do so. And in the end, you save yourself potentially hours of extra work having to jump out a fan motor and capacitor because trash got caught in the condenser.
