I’ve learned this from experience. A couple times I tested the capacitor on a CFM, changed it out and everything seemed fine then went on my way. Only to have the fan motor completely crap out in a day or 2. Condenser fan motors that are going bad will sometimes have to run a while before completely stalling out. I had this one call last summer where they said the fan motor made a really loud noise, which of course didn’t when I was there and seemed to be running fine. There was a slight bit of side to side play in the in the shaft, I talked the customer into replacing the motor because (knowing from experience) it will likely fail soon. Walked out to the van while the unit was still running, to grab a motor. When I was at the van (on the other side of the house) I heard this very loud screeching noise. I stopped and ran to the back of the house where the condenser was, the motor was practically screaming before it completely stalled out. The customer said something like “that’s the noise it was making!” …also, yes you made me yawn. 😂
"Leave me a comment if I made you yawn". Nope, fell asleep as per usual 😅. Wife says I was snoring even, but she was generous enough to wake me up (🎉time) and I got to listen to the video a second time haha.
Man, you sure earn your money out there. Talk about a harsh environment. Hope you use some sort of “buddy system” where one guy tracks the other. It would really suck to find out that one of your guys is passed out on a roof somewhere until the end of the day when he doesn’t come back. You can’t count on the customer because they’re distracted running their business. Stay safe guys.👍👍👍
Not one person can ever say you dont provide value for your customers' time and money. You handle even something simple as this....like a true professional. Thanks for sharing, Chris
Chris you can see the dirt buildup on the bottom of that housing, thats indicating oil, meaning failed bearing seals. Dry bearings and high ambient will cause intermittent lockup of that fan motor. Ive gotten my butt kicked a few times when i was a little newer, eventually put 2 and 2 together. At this point i always make note of it. I tell my customers two things when i see it, 1: We cant predict when that will fail, could be hours or years. But, 2: I cant remember the last locked up motor i swapped out that didnt have that oil on the housing.
Another great repair Chris, It makes perfect sense the condenser fan motor gets exposed to very high heat as all the heat generated by the condenser is sucked past that motor. Remember to keep drinking enough water in that heat as by the time you feel funny it is too late already.
And even if they do have ports for oiling which would make them last pretty much forever if oiled once a year they never get oiled. I don't know if any are made with sealed roller bearings, but the bronze bushing motors must be oiled from time to time in order to last. Otherwise it's replace and RTF again.
Yeah, you made me yawn but then yawning is 'catching' - once one person starts others follow. :) Not a problem since it's gone midnight where I am so you kinda did me a favour... Always love your videos, Chris!
Hi Bud, commercial tech here from NorCal. You’re absolutely right about trusting your gut and go for it. There’s so many “cap swappers” out here and don’t stop to realize the “tomorrow” of the repair. I do industrial ac now for a worldwide server room company and we still dabble into comfort ac and still see silly band-aid repairs.
Just something to keep in mind is that, if the capacitor value is low, the motor current will be higher. Not saying you made the wrong move. It might have been interesting to pop a new cap in and see what the current did.
Agreed on the motor current being higher with the weak cap... but once I opened the motor up and saw the damage internally I knew I made the right choice
At 113?? This old man would pass out !! No way I could take that 😮 my hat is off to you guys out there… A for what it is worth?? My customers don want to see me again on a call back. I have learned over the years if I think it needs replaced? I do it ! Saves me a trip back the customers money so it’s a win win
That multisocket shank also fits in their mulibit screwdriver handle so then you have all your sockets Philips flat head and torx bits in one handle and it's really nice to climb a roof with that and a meter for quick diags lol
Another excellent job. I really admire how thorough you are, and not in a way that wastes time and resources. Every company I worked for in the field would squeeze us on time and resources, which bred lazy and uninspired techs. I now manage my own team for a larger company, and my goal is to empower them to be thorough and not compromise their skill level. In time, they will become quicker, but it will he built on a stronger foundation of knowledge.
Hvacr I love your videos please keep up the good work you have reached me a lot and I’m just a teen I love hvac and you have helped me keen a lot about hvac please keep up the good work have a nice day or night
Yes i will use Mojave motors, I will discuss this live on UA-cam this evening 9/25/23 @ 5:PM (pacific) come over and check it out ua-cam.com/users/liveOjALDOBv4Jg
Huh, disassembled condenser fan motor in the thumbnail... This is gonna be a good one, isn't it? 10:13 - Kinda stating the obvious here, but there shouldn't be loose grease at the bearings, crud on the rotor, or discoloration of the rotor - all are giant flashing red neon signs confirming failure. It's a good thing the high pressure cutout kicked in, that motor quite literally could have burned up! The motor and capacitor were both on the cusp of tolerances; like you, I wouldn't be comfortable walking away from it without changing both. 11/32" is roughly 8.7 mm, so it's a common SAE size to use on an 8 mm bolt/nut. Slightly sloppy fit, but it'll do if the edges aren't rounded off. 😄
After you changed the Cond fan motor and were showing refrigerant pressures/SH/SC your SH was very low. From what I saw only around 5 degrees, did it ever get higher? At that low of SH are you not sending liquid back to the compressor?
Great video as always!! Q. I've always wondered, does watching the video while sped up affect your view count/algorithm? I watch from beginning to end.
So on those Carriers, whats the deal with that square knockout on the compressor/electrical cover panel? Sometimes I see then not removed, sometimes screwed halfway down.
OEM motors are easier to install, but I feel better using after market 80ºC rated ball bearing motors. Some of them come with 48" leads, but it isn't that hard to extend the wiring. People who leave the reversing leads sticking out of the top of the unit need their noses bopped...with a 2x4...
If it wasn't overamping: As a customer I'd ask what the motor would cost and what a second call for you costs if we go with just the capacitor and it turns out the motor is bad too. (just to know numbers) But most likely my answer would be: Yes, let's get both and be done. I prefer to spend a bit more and get it done right, most times that cheaper.
Before even watching through the video I can already guess what might be going on because I think it's similar to what I had happen to a residential unit I worked on recently. The unit would start and run just fine condenser fan motor ran perfectly for about 4 minutes at which point the bearings would heat up and the motor would lock up I'm betting that's what he's about to find with this unit I guess we'll see
Edit, surprising outcome I would have thought the bearings were going bad I mean technically they were probably from the same reason heat. But that's why you don't assume I guess.
If the machine have a overpressure problem and everything work as expected after resetting change the fan motors, I spend three days trying to figure out why the overpressure switch open in the night and finally the fan motor failed on office hours.
Must be nice when the customer has some comprehension of their needs and how that looks in terms of PM and when things probably need replacing vs the "let it all fall apart and call the tech only when it blows up". and then not approve half the quote.
Noticed the hose already out at the beginning so you were committed to washing down condensers. Did yawn but was already getting ready for a nap so it doesn't count though.
A cap being .5 or 1% isn’t going to be a the issue. Thats like expiration date on milk going bad at exactly midnight of the day the milk says it’s spoiled. 🙄
@@justme5384when someone talks about how far away it is almost always by drive time, US is big , most countries in the world is size of cities or a state here, like I work in the same state I live in right , but it is 5 hours of driving at 80mph to get there,

Condensers at that temp simply fail.. it makes no sense to use them in high temp areas.

just wana thank you for doing these vids! as if the work itself isnt hard enuff! u da man! MS boy here.
Another great video Chris! Those temps are nuts.
Nice intuition on insisting to change that fan. Even though you had the amp rating wrong when deciding, you knew it was a problem.
Awesome big picture view and root cause analysis with taking apart that motor and seeing what was causing it to over-amp! 🤙🏻
Awesome video 99F degree summer done in the Northeast states are nights are 40F & high 70s during the day fall beginning trees are changing colors.

Do you ever check your capacitors under load sometimes they'll show you they really are bad but will read fine when tested normally

Its there for a factory installed disconnect switch option, some people knock them out for no reason

That fan was well cooked.The stator looked in bad shape too.
Trust your gut in everything.
Wouldnt that be a perfect time to check that cap under load?
I was thinking the same thing lol

Nothing wrong with an aftermarket motor, just extend the rotation wires and pull them into the control section
Thats actually a good idea.

Thank you Chris, just starting work and you yawn!
Someone should make high temperature after-market motors for these areas. Save hours of driving and downtime for a little more upfront.
US Motors/Nidec makes the _Mojave_ line of condenser fan motors, they can run in 150-160°F environments.
