NICK-O I am so glad to hear that! I’m glad I could help and if you have any suggestions please let me know! Good luck out there!
@@AirConAcademy Hello sir! If I may suggest some things on schematic reading and/or potential and current relays. You may have videos on here and I have not gotten to them yet. If so I apologize for re asking. Thank you again.
NICK-O Please, do not apologize for making a suggestions. I always welcome suggestions. I believe I have a video on here about a potential relays. But you are correct I should do some more on Schematics and print reading. Again thank you for your suggestion I will look, check and make a note. Thank you!
@@AirConAcademy Thank you very much sir. It is an honor to get to experience your teachings. And I did find the potential relay video. It was fantastic! Blessings to you sir.

@@AirConAcademy Sir, I watch a lot of these so called hvac “training videos,” and many of them contain misleading or outright incorrect assumptions. That does more harm than good to aspiring technicians. I am a master electrician, well trained in electrical circuits and theory, and it bothers me to see people being given incorrect information by people they assume to be expert at what they are teaching. Many hvac techs, who might be well qualified in things related to the refrigeration cycle, air flow, etc, aren’t so well informed when in involves electrical circuits and components, and as you know, electrical issues make up a large part of an hvac service tech’s work day. So, it’s great to see people like you , who are well qualified, teaching this stuff correctly.
@@ibbriley399 wow! Thank you so much for your kind words! I really appreciate it and I try hard to get the correct information to the technicians out there because so many of them are just starting out. Thank you for your kind words and thank you for watching!
exelllent explaining

Thank you !!!
I likie your explaming thank you so much bro
You're welcome! Thank you for watching and thank you for your kind words!
Excellent explanation!
Matt Rodriguez thank you!!!!!
My condenser fan motor sometimes runs backwards. I replaced the capacitor, but still having the same problem. Seems like the problem happens with there is a power flicker due to storms. Whenever I have this issue, the outside unit is throwing off a lot of heat and fan is blowing downwards. l To correct the problem, I just turn off the unit and let it sit for a few minutes. Restart it and everything is normal. This unit is not a heat pump system.
Wow! That's interesting! The only time I have seen that happen is when the start winding is bad or the capacitor is open. It is the start winding that decides which direction the fan is going to turn. If you start winding is bad and you spin the motor in the wrong direction then it will run in the wrong direction. If you spin it in the correct direction, it will spin in the correct direction. First, make sure that the same line that feeds the run winding is sending power to the run, capacitor, and the run capacitor is attached to the brown wire that goes to the motor. Also, make sure that the wiring from the capacitor to the motor/start winding is good. the start winding usually is the brown wire. Then take a resistance reading across the start, winding to see if the winding is open. I know that in class I have taken the wire that feeds power to the start winding off of the capacitor, and given the motor a spin for the students to see that it spins in the wrong direction. So I know this happens. It could be also a problem with the motor in which case you may have to replace the motor.
I hope this helps. Good luck! And thank you for watching.
Great video which brightens more my understanding, I opened up a domestic PSC fan motor, I am trying to continuously change the speed using TRIAC, but there is no effect. it is still running, in some cases it is misbehaving. I wonder the phase differences are the challenge or what? I would appreciate your reply. Thank you.
That, is a good try, but a TRIAC is pretty much like a transistor and it will not work for this application. A TRIAC will allow the sine wave to go through but you need to basically stretch the sine wave out or compact it to change the speed. It is the sine wave that makes the motor speed up or slow down. Now that I think about it I don't believe I have a video on VFD's. Maybe I should do one as to how they work and how they are capable of slowing down and speeding up motors. Thank you for your question and I hope this made sense.
@@AirConAcademy Thank you, i made sense. that might be the reason the speed is not changing, however, if I try to vary the current flowing on auxiliary winding, by connecting the triac in series with the running capacitor, will it be worthy trying or? because I'm working on a project, using VFD wont it be an expensive way? Thank you.
@@johnclaud1057 no, I don't believe it will be worth trying. Because again you are not changing the length of the sine wave. You are turning it basically on and off. I have never tried that but I think what will happen is that your amperage will increase because of that the amount of heat will increase and you will just overheat your motor. Keep an eye on the amperage because by trying that he will be messing with the amperage and not the sine wave. I hope that makes sense. Remember, the VFD is going to stretch the sign without or is going to make it shorter and because of that we are adjusting the speed of the motor. Good luck and let me know how it goes!
Thank you.
I am glad you like the video, and thank you for watching!
What happen if the Run Capacitor is good and you give Rotor a spin with screw driver and motor runs?! So, you did say is 90% chance the capacitor fails but I replaced the Cap and tested fine also. But still same issue... ? Motor it will not start and makes Humming noise... if manually rotated it will run without any other problems.
How do I test and fix the Winding or connection or find which one has failed to it in PSC motors?!
You may want to check the windings on the motor. Don't forget single phase motors have a run and a start winding. You will check them the same as you will check the windings on a compressor. The only problem is we don't know what the actual resistance needs to be on both windings. There is a possibility that the start winding is going to be open and that's why it is not doing anything. So check your resistance and see how that works out. I hope this helps, and thank you for watching!
@@AirConAcademy , thank you for you answer. The winding are sealed together withe 2 power wire going into the Motor. So, in order to test I may have to unseal and could brake it myself. The day before it stopped working (starting up automatically) I smelled something burning. Could it be the connections are not sufficiently making contact?
I checked on load the 2 wires going into the Capacitor and indicate a similar Voltage of less then 50 V... Since the cap is rated at 230 V... could this indicate drop in Voltage for the Cap to start the motor?!
Is there something I could do? Or replace the Motor?
@@benweb1105 th-cam.com/video/vhjMsNSTRio/w-d-xo.html
It sounds like you may need to replace the motor. If you smell something burning the most likely the windings are bad. I just sent you a link on how to test single phase motors. I hope this helps but I believe you will have to replace the motor. Yes one of the windings is bad it could be partially bad so the motor is shot. Good luck and let me know what happens! th-cam.com/video/vhjMsNSTRio/w-d-xo.html
Permit what happens when the neutral is connected, and all speeds are connected
to the living end
👏👏👏👏👏
Can you explain how to replace york chiller pcb
Sir I saw the comprassor is starting with only two wears how it is possible .
it can happen if the problem that ruined the other compressor was not found. I mean if there was acid in the system and if the lines were not properly flushed it could have ruined the new compressor. Also if new driers were not changed or installed that could have done it, it should have HH driers if it was a burn out. Was the superheat checked when the new compressor was put in? if not it could have been what ruined the new compressor. Also was the contactor changed? the old contactor could have ruined the old one and the new one. There are a lot of reasons. When changing a compressor there is a lot to check and do during the replacement processes. I hope this helped. Good luck and let me know if you have other questions.
Show the kids a shaded pole motor.
LOL Ok I will see what I can do!!!!
