1:04 wow 😨. what a minute. you should press stop 🛑 first. I don't know how many ton that unit is, but the breaker panel could explode in your face depending on if the system is fully loaded. I recommend pressing stop 🛑 on larger systems like that.

[@bobpaulino4714]

It's hard to stop a trane. Even harder to get the parts to get them going again ! Love these outfits generously giving us fixed times for warranty repairs when we use up their allotted time JUST getting our tools across these it center and (what's left of the) mall roofs.

[@AllTattedUp13]

I used to service a mall that had rubber tension roof with small ass gangways to walk on. Kicker is, since it was rubber, mall wouldn't let u carry your tools across it, not even in ur pockets. Everything had to helicopter craned to you. Don't matter if u was just changing a capacitor. Heli crane had to come in lol. Shit was nuts.

Brother You forgot the rain shield on the new motor, sometimes they come with them sometimes they don't Shaft up orientation you need the black small plastic rain shield without it motor will fail prematurely

[@JumpingIntoHistory1944]

I always change the fan blade with the motor. There's a reason that motor seized up and a lot of the time it's from an off balanced blade. Plus sometimes those blades don't want to come off and you end up bending them while using a puller

[@hackendan1921]

Unnecessary expense. If you clean the shaft and put some oil on it you should be able to slide it off no problem.

[@jasonjohnsonHVAC]

We always replace the blade as well.....its cheap insurance and the customers will always go for it...haven't had one yet who wouldn't. These are expensive pieces of equipment...customers don't want breakdowns....they don't mind spending a few hundo more for a blade too. Had lots of issues with Trane motors....had 2 bad out of the box condenser motors from Trane for intellipaks last year in a row. Plus the counter guys aren't that great and seem to always screw things up.

​@@jasonjohnsonHVACwith u on this one bro, counter guys aint worth shit these days. You'll have 1 guy in there that knows his stuff, the other 3 or 4 guys are just empty bodies taking up space.

[@DonnyM-q5t]

Great video. Honestly though, I would not have replaced the contactor unless there were signs of wear like arcing or heat damage. From the video, it looked like those contacts were as good as new with no other signs of wear or damage. Changing a perfectly good part like that is just a waste of materials, time, and the customers money.

[@IQDave]

One thing to remember is for large commercial units, downtime is way more costly than installing a contactor. I’m not a fan of the shotgun method usually (replacing all suspect parts), but can see why he did it in this case. He brought the parts up and not much cost to replace while he was there. It wasn’t HVAC, but in my field engineer days, often travel time (high cost) was a huge influence on whether or not to replace available parts.

[@robertdavenport9095]

[@UpnextLetsGetIt]

[@MMatte75]

Great job. I also recommend changing the prop as well I have seen over the past 30 years the fan blade rivets go later causing that new motors bearings to fail. For the extra cost of a blade it’s well worth it plus you won’t have to worry if you bent the old prop while removing.

[@AllTattedUp13]

I'm with u on this one. Not to mention some them fan blades are damn near welded on. Not worth the time or struggle.

[@mylesmackey2430]

Great video! I’ve worked on maybe 10 different intellipak units in my last 9 years in the field. I’ve never worked on one that the test mode actually turned anything on! Or that the knobs you tighten to close the access panels didn’t have the threaded inserts just spinning in the sheet metal! Also really like the foil tape on top of the hub trick.

I'm not a pro, but more of a DIYer. Just eye-balling these commercial units tells me the quality is several notch above the residential units. Seems to me they are also easier to work with. No crawl space, attics or obstacles hindering access to the unit.

[@arthouston7361]

I always get a new rain shield when I'm going to do this on a rooftop unit. The old motor had a small one, but I install one that gives me assurance that the upper bearing does not get rain or snow on it. Otherwise, good job.

[@AngelHernandez-bz1is]

[@Chris-mo9gt]

Just had an a/c replaced due to not cooling great, definitely still blowing cool air though. It’s R-22 though so recharging with new stuff isn’t allowed. The unit was 42 years old and had to be replaced with something that if lucky it will last 15.

How about adding silicone to the shaft and hub . I been doing that for years . Tape will deteriorate over time 🤷🏻‍♂️. Good video

[@zerokelvin6639]

Great video. The only thing I would have done diffrntly, is to disconnect bad motor b4 leaving 1st time, just in case its not gonna overheat and cause entire unit to go down. When motor is locked, and still in circuit, it could cause issues. Other then that, great video and big fan!

Good job Zack but my experience I would replace the fan blade to you never know the fan blade can be out of balance and took that motor out. My experience I did a condenser fan motor one time I went back couple days later on a call back the fan blade had broken off. I did inspect the fan blade and everything’s fine. I think what happened in the fan blade was out of balance, just my experience.

I am happy to say that I am glad I chose this path of learning a trade.

[@efficientheatingcooling]

I always show up to a condenser fan motor change with a new blade. If the old blade is in good shape I will save it for emergency repairs. I just see so many blades on older units unwilling to come off the shaft OR have micro cracks in them. I've also seen a handful of blades that cracked and went straight into the condenser. I will admit in your case that blade does look to be in descent shape. I have also made the mistake of putting my puller on the blade hub and accidentally hitting the set screw holes. At that point, it's game over and time for a new blade. Had to learn all these things via experience.

[@jarredmaurer2078]

I’ve got a 10 to condenser with a restricted filter dryer. Should I replace all the refrigerant with new refrigerant or pump it down and replace the dryer outside the condenser?

[@Captinfishwilly]

I’m going to a tech school for hvac, but they really only teach for residential and not commercial or industrial. I’d rather do commercial than residential. Any pointers to where you started? Or to point me where to go after i finish my classes? Just a little stuck on what to do and where to go. Thank you, love the videos!

[@DavidHernandez-gt9bo]

Good stuff !!! Great troubleshooting skills !!! Working smarter not harder .

[@austrianpainterinhiding88]

Is there a separate board controlling each of the variable speed motors? They each just came right off the contactor it looked like. I assume troubleshooting that would be more complicated? I don't work on a lot of Trane, as you can probably tell, so I really did appreciate the video. Thanks!

[@Adam__941]

Why replace the contactor? If you had proper voltage going to the fan then its most definitely the motor having issues. and after seeing how locked up it was that was definitely the problem.

[@MiguelAngel-ir3ck]

[@myHVAClife]

Just curios if you bill the customer for all the time you spend setting up your camera angles, after you closed the roof hatch you had to go back and get the camera! Also would love to seen you actually break out a meter and actually troubleshoot that motor and why does it need a new contactor if it is powering the other motor correctly or are you just being a parts changer and loading up the invoice? Absolutely no actual training value, maybe explain the amps and specs rather than just saying LOOKS GOOD TO ME!

I had a number of those units where the wiring harness fails at the fan. In other words, the motor was fine, it just needed some adjustment of the wiring at the motor. There's a little rubber device pretends to fall off. Did you check this before ordering a replacement motor? I could easily see checking that wouldn't produce best content, so it might be something you just didn't post, but did none the less.

[@joshuaricks7730]

This is true. However, when all of the other fans are running that motor should at the very least be running backwards if the motor is free spinning. If that motor and blade is not even spinning while the other fans are on that motor is definitely bad.

Lets talk about other good things to do and not saying what you did was bad at all no sir ! Good stuff !! When a hp occur and you need a motor, should cover the hole of the fan shrout with cardboard or something to prevent other hp trip and getting cooling.
