- In this episode we cover what the wiring diagram means on condenser motors and how to wire your new universal motor. UPDATE: If you want to see a longer breakdown of the wiring you can find it here: • How To Wire Condenser ...
Very Very Good Explanation. I called the guy that I usually use. He didn't return my call. I did it myself with your great explanation Thank You so much.
I watched seven different men tried to tell me how to do this And I watched you Who taught me how to do this It actually worked Nothing the other guys said was anything like what she said and it made so much sense and it was so easy Thank you
You feel my pain then. Hard to find info on a 1979 carrier compact
I love to see a woman doing this kind of work. I hardly see a woman out there in the field for Hvac industry.
Best sheet metaler I know is a woman.... her work is so clean.
I couldn't help but notice, the old motor is an 8-Pole, designed to turn the fan ~820 RPM. The replacement motor is a 6-Pole motor, intended to run the fan closer to 1,070 RPM. The torque required to turn the fan increases on the square of the increase speed, multiplied by the RPM, thus, the power requirement goes up on the CUBE of the increase in fan speed. If the increased speed is needed for the extra air flow, the new motor needs to have at least double the horsepower rating!
Very good presentation. Thanks so much.
I use 120 volts ac for 1 phase motors.
I got run at fan of the capacitor to 120 of the contact output and common from the motor to the other side of the contact .
And I put my start winding from the motor to common of the capacitor.
Very good results and readings!
That means the capacitor is between start and run of the motor.
She said we need that other capacitor “if” the new motor takes a different size, but what do we do if it doesn’t take a different size?
Nice clear explanation. Thanks for posting the information.
So how about if the specifications on old motor dont match the specifications on the unit specifications then what???
Universal motor drain plug on bottom end is not just a plug I can remove it’s some kind of hardened resin.
Do I need to remove this?
So with those, it's a hard plastic that I normally have to remove with a box cutter under the lip of the rounded plastic and pop it off. They are a pain to remove!
The Vevor 1/4hp 1100rpm condenser fan motor I received is a ball-bearing motor, not the troublesome bronze oilite sleeve bearings. Unfortunately, vevor drilled (and then installed rubber plugs) drain holes in the top, not bottom. That's how I found it's a ball bearing motor, while dissassembling and drilling drain holes in the bottom.
I liked that it helped me out a lot thank you very much
This is one the best presentations I have seen on this so far. Pace and explanation very details.
in my case I bought a replacement condenser motor fan, which came harnessed so I have to clip the ends in order to connect it to my capacitor and contractor. However I have 4 wires : Black, Purple, Green-Yellow and Red.
The. original motor was Black, Purple, Brown and Green. I am assuming the Red and Brown are same, is that correct ?
I was not able to find and reference online.
You said never change your HP but sometimes when factory OEM motors supersede they change HP without changing the fan blade. I see this happen all the time with Goodman and Trane fan motors.
Yes, they do sometimes change the HP on factory motors. I've seen that on both Trane and Carrier units. I think honestly it isn't an issue until you jump two or more up. So, say, going from a 1/8 to a 1/4 is not a good practice and would cause some amp draw issues.
@@opentopublichvacschool i rather go from 1/8 to 1/4/....than from 1/4 to 1/8
Thank you very much… very informative and please know i shall be subscribing to the channel
thanks for covering the 4 wire motor. I take it the oval capacitor non-polarity is used on 4 wire
the round c,herm,motor is used on the 3wire motor?
Are they interchangeable if so, how would that look like?
Thank you for your time and knowledge

@jollyscaria1922 huh?
I had a motor put in my furnace with the yellow white. The brown and brown and white all hooked to my capacitor. Ground wire is not hooked up
Hey great video.
Very clear.
What about motor drain plugs.
Question about wires?
You didn’t say where in the Contactor the white and black wire goes either T1-T2 or Line 1 Line 2?
Hi, For my fan motor, I have white, black, Orange or red, purple, purple with white dashes... The wires that appear to be purple you are calling brown. I have either a red or orange cable... Where does that go?
I wouldn't be able to tell you without having a wiring diagram. Colors are really sketchy things to go by, but from what I can tell it sounds like you have a 2-speed condenser motor. You can check our other video we recently uploaded that breaks it down further. Usually red indicates low speed and black indicates high speed. Again, I am not going to tell you which is correct because I do not have a diagram of where your original wires go.
Try this video, hopefully it will help. Let us know if you have any other questions!

I have a black wire. It's just hanging coming from the fan motor where should it go
Jeez, I wish UA-cam would always alert me when someone asks a question. Sorry I wasn't able to answer this for you right away. Color can vary from brand-to-brand, so you would need to check the wiring diagram. Most, but not all, use a black wire from the motor to the contactor. However, not all of them do that. It's really important to check how they are labeled. If the wire goes to something other than the motor you would need to trace it back to the source.
I have the exact motor you have in this video (4 wire), but I dont have a seperate capacitor, just 1 capacitor for comp/fan. so I am unsure how to hook my 4-wire motor up, the one coming off is only 3 wire. :( I have Black/White and then I have Brown and Brown+White Stripe. The verbiage on the optional 3 wire connection is exactly what it is on your unit, but it doesnt make sense to me
on most universal fan motors.....you can tape off the brown and white striped wire and use the other one...that is solid brown...,as a three wire...as long as the dual capicator you have matches the mf...of the new motor,,,,,
@@charlesjackson9602 so is that to say that if the mf on fan motor doesnt match the dual capacitors mf thats where the need for the 2nd smaller capacitor comes in?
@@MrsBuddevil Yes...or either get a dual one with correct mfd..
@charlesjackson9602 but the mf on the capacitor should match the compressor too, correct?
@@MrsBuddevil Yes. has to match the compressor ..i keep like 35/ 5 and or 35/7.5 etc
i wish all the universal condenser fan motors would add length to reversing leads. so you can reverse in cabinet...or do another way instead just hanging....it annolying and hard to place.the reversing leads...especialy when they are opposite the main wire leads...i seen contractors strap them to conderser sharpe edges...vents...and short out...looks bad too..
I agree! The only brand I've come across that does that is a private label wagnor motor from Rheem.
I only have one single capacitor, why?
😊
Ok the confusing part. Is u don't already have 1 leg of power hooked up with the compressor. Ur video without sound u o ly have 1 leg of power to the fan
I don't want that dream
Real
confussing
Worst video 12 minutes talk nothing understand 😡
What part are you struggling to understand? Wow. 12 minutes, what version were you watching? This is a 7:10 video.
