- This York chiller VSD failed, had a SCR short out and a capacitor blow. Replacing the full power assembly. HVAC technician should get a lot of use from this as a hvac training videos. Chillers are just one big air conditioner doing what AC do.

I don't know how you do it but your wealth of knowledge and how to troubleshoot is this so extensive
your doing such a big help to HVAC family throughout the world. we family's of HVAC whole world thank you so much.
Allan allan ferandopower full jobe doing such big jobes famliey not jobe ony side whole world all unit no only shreing song helpunfull big tankyou sir
The safety fuses blew because of the drive failure, not the other way around. They are designed to react faster than the circuit breaker to prevent electrical fires caused by an arc fault that a breaker cannot react fast enough to prevent. Breakers are for protecting wiring from overheating, not to protect equipment.
Recently moved from Marine Industrial to Commercial and familiarizing myself with equipment. Huge thanks, bro!
Always, thats why I'm here. Everyone has a opportunity at a great life with just a little info to get them another step further.
instablaster.
I don't see this kinda system very often so thankyou for the videos Sir.
Another job of the input reactor (choke) is to keep the switching noise from the inverter from going OUT of the drive onto the line input.
Tggokol"….
Firstly, thank you for this useful video, and I see you working with confidence and this is very good. I hope that in the next video, you will explain to us how to change the oil of the compressor and take out the oil from the oil separator and bye until you watch this video
Great Job explaining the technical side of the drive, thanks for uploading
I am watching all your videos.lot of knowledgeable keep updating
Nice video as always. Thanks. Kindly make video on water chiller complete parts along with power and control wiring
Ill see if I can get one together soon.
sir can you explain about VSD how it works and how to trouble shoot
Great Video for sure. A lot of knowledge.
Great job and very nice
Yes brother its amazing can learn to installation method.
I thought my job looked tough👍
Great video
Thank you!
Nice job sir
Gret video. Not sure where you buy your parts but its cheaper to rebuild...save in the tens of thousands to rebuild vs new unit. I have rebuild SCR/IGBTs and capacitors in the drives identical to this one and spent around $3,000 for parts
Excellent Sir
Saludos. Tengo un problema, cuando conecto el modulo variador se activa se apaga el equipo por proteccion externa.
Thank you so much bro for explaining.
great job
Awesome video
Hopefully it's helpful for my future thanks 👏
Awesome video. Like hearing the explanation of what your steps are. How long does something like that repair take. Looks pretty evolved.
A full day
yeah.. digging through those scr are pain in the ass.. specially at 39C in the middle of the day. but unfortunately for me, I have done so many yvaa replaced with shorted or open scr or if im lucky the igbt's.
I want to ask you a question, dear, after how much time is there a chance of it getting damaged, this is the gate driver and the module power capacitor.
Very infomative video..
chiller york ykfdfrq75clgs - faulty
VSD-HIGH DC BUS VOLTAGE
Do you have video tu solve this faulty
Buenas tardes,
Mano le tengo una pregunta, en vista que un chiller dónde he Sido llamado para chequearlo, me he encontrado que se llevaron todo la parte de control y electrónica.... Pero el cliente necesita saber si los motores ventiladores y compresores es Buenos, por lo tanto; me gustaría saber si es posible alimentar solo el compresor directo, al menos como prueba, para saber que está comprimiendo.... Está prueba se hará en vacío, sin carga y sin conexiones de tuberías....
Es decir; la pregunta es:
? Puedo energizar el compresor con voltaje directo sin el variador, solo para pruebas de funcionamiento.... Saludos y espero sus comentarios.
Very informative video
How we know the coolant level for the drive
Great video, do you have the torque settings for the main fuses and the compressor harness leads?
Nice job 👍
Thanks again...
how to set the fluid level control for yvwa york pack type chiller .. from system module ?? 🙏
Nice video presentation , would like to know more about IGBT gate drive fault what to look for.?
First thing to verify is control plug. Make sure pins are properly pushed in.
@@HVACTIME is there a service manual on how to properly troubleshoot this? Incase the customer doesn't want to go with the whole replacement.
This is a fantastic video!
Thanks a bunch
What series of York Chiller is that?
Looks like one of their YVAA line
YCIV
Who is the guy asking you all the questions in the video ?
Customer watching job and helping film.
Excellent boss
great vedio man
Hello sir I want to know how to clean heatsink in YK chiller pls inform me!!!!
hello bro.. what might be the solution for having a VSD run relay in all system? recurring fault
Sir Can u explain about glycol how to fill and how to check level.
For me the same chiller vsd capacitor blast 💥 what is the reason can you please explain me.
Thanks
dear i have YVAA chiller IGBT drive replacement. could you send some tips on YVAA chiller IGBT replacement. thx
Very very information
nice job
Sir! Kindly how can test by multimeter of IGBT good or definitive
please let me know how to handle when the resistor on the DC bus cannot fully discharge below 50V.Im from Việt Nam
It needs new bleed resistors. You can use a meters with a built in resistor to bleed it down.
Please send more videos sir
Have you ever replaced a YORK PCB GATE RESISTER INV BOARD
Yes, what you working on?
@@HVACTIME Thanks for a respond. I have this part and want to know which unit this part belong to(Johnson Controls PCB Gate Resister INV Consair (240) 031-03052-001) . Thanks Joe
Do you have a video on how to change out the resistors, I have a rental I have to do Monday
No, not specifically but its very easy to do.
Hallo sir,
If in VSD assembly capacitor is getting smoke & smell then need full VSD Assembly should br change or only capacitor need to be change.. what is the reason for capacitor getting
If all the other components check good then you can just do the capacitors.
@@HVACTIME Thanks you very much Sir...
@@HVACTIME Sir,
Alarm Showing ( Precharge - DC Bus Voltage Imbalance )
And after clear the alarm start the chiller after 2-3 minutes little smoke comes near Capacitor so what should be problem and what should be change...
Pls. Help and reply...
Thanks a lot...
First stop resetting the chiller. Sounds like you definitely have a capacitor issue and possibly a SCR issue. You need to get someone on site who knows that drive and can fix it.
@@HVACTIME Thanks a lot ...Sir...
Sir vsd high passplate temperature what problem sir please send video sir
Hi Sir you have video to remove the SCR ?
Not yet
What is scr please
YOU MAY ASK TO THE CAMARA GUY- IF THE INVESTMENT IN A CHILD SCHOOL 🏫 IN A GUEST 30K OR MAY NE MORE- HE ASK QUESTIONS TYPICAL A OFFICE GUY WHO PROTECT THE MONEY FOR OTHERS-OTHERWISE HE GOT FIRE 🔥- SHOW HIM BRO 😎 HOW WE DO IN THE FEEL- LUCKY HIM THAT WAS YOU -LMAO-
I HOPE THEY MAKE THE CHECK AT THE SAME SPEED WITH NO OTHER QUESTIONS
Only about 4 grand more for entire assembly and 90 day warranty irregardless!
hola hermano ecesito ayuda con un ycav

Do you do any medical chiller work ?
Yes, variety of them.
@@HVACTIME I work for KKT Chillers technical support. Nice work you do .
What is the possible cause on yvwa screw 171hz demand but the compressor amps is 40%FLA. Thanks
Im not understanding your question
@@HVACTIME we have trouble york yvwa model chiller the problem we found is compressor stays at 40%FLA only even if the vsd demand is already at 171 hz. Even if vsd demand decrease still stay 40%
To be clear no matter what speed it runs the FLA doesnt change from 40%?
@@HVACTIME the alarm is low discharge superheat. But base on system parameters all other inputs are good except those compressor amps not increasing. Thanks
@@HVACTIME yes correct.. what are possible cause?
Hi How Are you sir
Is it just me or did the audio and video get out of sync?
sir York YMC2 Magnetic Chiller VSD - HIGH PHASE C MOTOR BASEPLATE TEMPERATURE PROBLRM Please solved the problem
Have you done a full inspection of the drive?
@@HVACTIME yes sir over and over same problem
please sir give your whatsapp number
@@sazzadhossain4372 has the motor been megged and what are your input voltages?

UNIT FAULT :

Rookie. No need to drain the coolant system.
He handled his questions with pazzaz
Might have been required for warranty validation on the new module.
