Please note that the power source should be disconnected & the compressor should be isolated with no wiring connected while testing continuity or resistance. When checking amperage, the power must be on for the compressor to start. Thank you all for watching & commenting!
3 phase motors don't have a common, start, or run terminals.
All 3 phases are energized at the same time, and the motor rotor "chases" the phases around the stator.
don't confuse him with facts, he wouldn't have lasted till lunch his first day on any job I ever worked
Yeah Einstein, anyone of us that has been in HVAC tech school or a service tech that learned OTJ knows that. Your C, R and S terminals on a PSC compressor are all three energized at the same time too.
Thank U these educational videos helps a technician a lot
You're very welcome & thank you! I'm glad these videos help🔧⚡️
Thanks JMT there is value in all your videos keep up the good work man and stay safe!
love your training videos. great explanations & easy to follow. thanks for sharing the wealth!!
Thank you! Glad you enjoy the training videos. Appreciate the feedback🙏🔧⚡️
Excellent video. Well presented and explained. Thank you for posting.
Interesting video. Well presented and explained. Great job JMT as always
Thank you! I'm glad you found this video interesting & well presented. Stay tuned for new videos every week🔧⚡️
Concise and very informative as allows without the flim flam 💯👍👍👍
Thank you brother loving your videos!
You're very welcome & thank you! Glad you're loving the videos! Stay tuned for new videos every week🔧⚡️
Thanks, good video.
Great video bro
love your videos bro very informative.
Wow what a great great video well done Luis Chicago
Thank you Luis! Appreciate the feedback🔧⚡️
Great video!! well done
Now that's how you do it ... Nice explanation ... Thx
You're very welcome & thank you! Appreciate your support 🙏🔧⚡️
Great Video. Thank you for sharing. What's voltages 3 phase inverter compressor use 120 V or 208 V or 240 V ? Is this compressor come from VRF Muti V condenser unit ?
And of course, Jumpermantech always has an inverter compressor in stock. Thanks LG. LOL!
I had 6 LG BAD inverter compressors that I had replaced in my house. Had to do a little spring cleaning but I saved one for videos 😂 Thanks for watching & commenting!
Very very great video
Thank you Scott! Stay tuned for new videos every week🔧⚡️
Thanks for the upload. I have a question. You said measure AC current on DC compressor. I always thought it should be DC current on DC compressor. Do you know why it's AC current? Thanks.
awesome video
Thank you! Stay tuned for new videos every week
Great video
Thank you!!
Great video.
From india
gracias señoron
I'm getting the exam exact reading 15.7 across all three legs but when it calls for cooling the compressor cuts on but my low side and high side are staying equalized at 290 they are not adjusting
Excelente vídeo
Gracias!!🙏🔧⚡️
excellent explanation and a great video thanks.
You're very welcome & thank you very much!
Below 30 megaohms is not always an indication of a failed compressor. I can only speak of knowledge specifically a Copeland. AE BULLETIN 1294 covers this topic. A Copeland scroll can have a megg reading of 0.5 megaohms and still be an operational compressor. A lot of other factors also contribute to a low megg reading....temp, moisture, contamination....a better way to look at a megg reading is if it goes up...then starts going back down. You should also use the PI ( Polarization Index ) or DAR ( Die Electric Absorption Ratio ) tests, they are a timed tests and produce a ratio based on sampling meggs at different intervals.
Im not saying that compressor wasn't failed. Just wanted to share a little info.
Anything below 250,000 ohms indicates the compressor needs to be replaced from what I learned in school.
I have always read that you never check a inverter dc motor with a megohm meter. It does not mater what size the inverter motor is, there all 3 phase windings.
I have a question. I have this compressor, a spiral condenser, a water regulating valve, and 2 txv. I saw something strange that I didn't understand. When I started the system the whole compressor was hot and the receiver was cold including the liquid line by the filter. The bottom txv was frosting at the outlet side just a bit and after a few seconds I saw it instantly melt away. The compressor made a funny sound and the suction pressure when up from 6psi to 60 psi. I'm a new tech so this is all new to me. Why do you think that would happen? I think there's a blockage in the system and I was close to witnessing my first liquid flood back. Do you think there's air in the system? Possibly both?
Possibly a blockage or maybe overcharged. Did you get an amp reading from start up?
Should you recover refrigerant when testing with a Megaohmmeter
No but if there is a lot of liquid in compressor it can give a false reading in megger test
👍👍👍
🙏🔧⚡️👍
3 phase doesn’t have a start and run winding
And VRF always labels them U,V,W....its all the same thing in essence. It is misleading calling it a start and run winding. They have different resistance values....hence why a capacitor is used.
Class in session
That is correct! Haha thanks for watching!
I`m korean video great`s
😻💚💜💚

Sir good day sir can I ask a favor I'm a aircon maintenance in university here in Philippines sir the one of ACU LG Multi V 5 is not running but no have indicate error sir and the out door is not running what is the problem this sir? I hope you read my message for you thank you so much sir.
Check for power
@@LC-qi5ff thank you sir
Hi sir I'm
HVAC SUPERVISOR
Plz request help me
My side have LG inverter
package unit discharge pressure 220 coming that time tripping unit 3 phase plz help me sir...
Enjoy watching your videos. However i would encourage to to do a little more research, may be judt a vocabulary thing.
When you check the resistance of the motor winding that will give you a resistance value in ohms it also is telling you whether you have continuity or not, essentially they are one in the same.
Another thing to mention is that when dealing with a 3 phase motor you DO NOT have a start, common and run windings.
Dam man your fucking bad ass 💯💯💯💯💯💯💯💯
