Great video

Question: Is condenser fan motor a "single speed"?

Great explanation!

If using relay, is run wire broken on run side, or does board do this since there are 3 speeds?

120v gas furnace motor? What size wire? #12 romex? What size breaker?20amp? On average, how many amps does 120v motor pull?

Great info.

Question I have a 4 plus the ground cable hvac motor blower Emerson brand old type internally procteted two cable on the capacitor only,which wire will be the hot wire black,red,orange,brown?

Thank you for the great video!! After narrowing down the probable issue with our AC unit to the capacitor, I looked up how to replace it. Your video gave me all the information I needed, along with the confidence to do it! Our AC is back on, and all it cost me was a little time and effort and a $25 part!! Thanks!!!

For anyone who actually needs some actual information, I'll make this comment. I know almost nothing but somehow I know more than her. - The fan blade could potentially warp or fly off (but I don't know at exactly what speed or the very specific factors, I came here hoping for any additional knowledge.) - If you are getting the same HP motor then it will have a difficult time keeping up, so if you are considering it you need to at least get up to 2x higher horsepower. - It has literally nothing to do with how AC works, how motors work, anything she wrote down, or capacitors as long as you understand that you obviously still need to make sure it matches the motor as you would if you were going with a lower RPM motor.

Thank you for making a 17 minute video where you do not answer the question at all in any meaningful way. It was definitely necessary to spend 17 minutes to say that a higher RPM is a higher RPM, and that you don't know how to actually calculate anything in relation to what fan blade should be used, pretending as if the fan blade cannot be replaced, that it's difficult to replace when you have to pull it out anyway, and then topping it off by saying that somehow a higher performance motor is in some way negatively related to the longevity of your condenser like it would not literally be the opposite of what you said, and of course never elaborating on why it's bad or what actual problems it could cause.

The start capacitor doesn’t cause the motor to start by providing a “charge”. The cap causes a phase shift between voltage and current. The resultant phase shift allows the motor to start.

I have a motor that has no info on it. I just ordered a 1100 rpm 1/4hp motor because it would come sooner than the other motors. Do I have disaster in my future?

Can i use a 1/4 hp to replace a 1/6hp Thanks

Hi I I have a problem with my Ac blower ithe motor run to slow

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!

Not sure if you mentioned it but for the next guy. The number one of the five control wires is a PWM Signal. Motor switches to Variable Speed mode when a PWM input is detected. took me a while to find that little bit of info. One other thing, the narrator is super cute.

Thank you

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?

I love to see a woman doing this kind of work. I hardly see a woman out there in the field for Hvac industry.

So how about if the specifications on old motor dont match the specifications on the unit specifications then what???

Buying a meter is MUCH cheaper than paying the sheisters that will come out and troubleshoot your AC for you. I had a company doing a yearly check-up on mine and they said my capacitor was low and the charge would be $325 to replace! It is literally held on by one sheet metal screw and cost about $25-$35 to replace. He already had the cover (4 screws) off in order to check the capacitor.

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

Way to much talking

What if it doesnt have a brown white

Hey, what's up chicky? I watched this the other day to fined out what the commands where on my 4 speed. And you said you sometimes seen the command on a 3 or 4 speed as the purple wire and that's exactly what the command wire was because it didn't have a white wire and that's how the motor come out of the unit. Thanks 🍻🥂🍷🍹🍸

Thank you very much, excellent explanation, good day. Helpful

ran into a Heat pump that had at one point had an ECM Blower but someone put in a PSC blower. System had high head and suction pressure and was not cooling. I lowered to low speed and it stopped having High head and suction pressure and is now cooling. Just FYI if anyone runs into that.

I only have one single capacitor, why?

I just have one single cap. why?

Can i use a 1/4 hp 1075 motor to replace a 1/3 hp 825rpm motor? My tech did this and it has been overheating. He doesn't seem to think the motor size is the problem, any suggestions?

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!

Great video, thank you

Speed 1 on motor is automatic and connects to G fan and that’s it! Please converse with me on the ecm and psc models and pulse width modulation in laymen terms!

G is only for fan Y is cooling speed W is heat speed And Y and W work on automatic? Is that what is happening with that unit? Also Y branches out to outside unit condenser! W branches to turn heat relay on for heater to turn on! What is your complete talk on that?

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

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.

1 question please if it is possible 🌹🙏 Q ? furnace work fine , tech come in for yearly service , after 40 minutes he works on it & I ask him what did you please ? he responded checking gas pressure .After he left our furnace does not work like before , we use to set the thermostat at 75 at night time ,our house was warm but nomore .Now if we set it at 75 , our house has to go to 72 degree so the heat kickes in , now we have to set it at 76 or 77 degree so the furnace works only 10 minutes then we have to go to raise the heat to 78 . My wife has checked thermostat twice , nothing wrong , the whole furnace is only 2.5 years old . When we call what you have done to our furnance they hung up the phone on me or saying it is our emagination . . Now our furnace only work from 76 or up . We are in Va is : we nomore thrust them although we have paid full amount for about 7 years warrenty) I thank you for respons 🙏if you can .

Hi again , What's the sign of over heating please👌🙏🙌

What's the restriction on gas presure ? I thank you for your response 👌🙏🙌🫴🫵🫶 Nice video 👌🫵🫶🌻🌷🌸🌹💐🥀

I understand about rpm, would the horse power matter as much?

Liked video on how to check limit switch circuit

Your video is of no help. I need actual in the field. This is an air handler, an older one. This is an old style blower motor. This is a new Star blower motor. None of the wires are the same colors and go. That's what I needed and you failed to deliver that to me.

great friggen point about sanding the shaft.

So that's why there are so many wires coming from my furnace motor. 👍

What would happen if a 3 speed motor is wired for 1 speed only (white [as common] + black is wired as "high") and the 2 other speed wires are not properly parked or wired off. For example if the low/med wires accidentally touched the furnace housing (short), or the 2 wires touched each other.

To much talking ,just tell me what the damn symbols mean !!! OMG !!

What if my original wire has no common?

Thank you very much… very informative and please know i shall be subscribing to the channel
