Yea so true ... I feel like most of them is just reading the manuals and learning the manufactures specific issues /codes. Everytime I go to a new one it's pretty much reading a manual for how ever long it takes to find the issue. But ya as long as you understand how they are installed and how to find the error codes they aren't that bad . Only a real problem if it was never installed or serviced correctly Its hard to show up to a call and expect the entire system to be working how it's supposed to . Especially when their in house maintenance says it never worked properly from installation lol
Good video. Just for the future as you will likely see a lot of issues at that job site… In this case. Your error is actually 29-1 29 is the error 1 is saying it’s the master unit. C1 is compressor 1 and the 1 by its self says it happened 1 time. If you have a slave and had an issue on that unit it will read 292 or 29-2. Also the compressor is an inverter driven compressor and runs on AC not DC. The CFMs run on DC. The suction driers are a bad sign. There seems to have been alot of issues there. The suction driers should have been installed with a bypass and after the clean up from the burnout was complete it should have switched to the bypass. That drier should not stay in place and needs to be removed. If you haven’t done so already get the LGMV service tool for the laptop or mobile. I prefer mobile as it is easier to use a phone then computer but to each there own. Good luck and keep up the good work
I’m amazed these units sit outside as they do. If it had been pouring rain that day, would you have done this diagnostic work or waited until it dried out? Nicely done, guys.
That SL drier is best installed vertically you otherwise need to add about 1/2 quart of oil that sits in the bottom of the canister that never returns to the compressor, and with the Hassel of removing that pig, with that beast out of the way, why would you not replace those vibration eliminators that always leak.
Hello, I always appreciate your technical videos and am learning a lot from them. I'm currently watching your LG VRF troubleshooting video. Could you share the LG troubleshooting manual you have with me?
Very good video. I’m fascinated by those LG units. Got a question for you, was it just a trick of the light or did the black wire going to the compressor look like the insulation had rubbed off in one spot? If it was maybe it was intermittently short to the front cover?
Good job Jumper, Yeah, Klein makes a better mega ohm meter or megger old school electricians call them, megger is a name of one of the manufacturers that started making them, but yeah, the Klein gives you digital read out or better reading on resistance values, than just a lighting display, the Fluke mega ohm meter is super expensive, Good job.
Hello, please tell me the error c1_1 (211), when you restart the chiller, error 22 comes out - what should I do? - so far I have found that 1 compressor for 50 amperes in my 3 phases calls to the ground of the order of 100-150 ohms, I threw it away the inverter board is working (I sin only on the current sensors on the board itself) - but not a fact 😥😥😥😥😥😥
I have a Lg hm 123m u 33 type heat pump, error ch29 occurred. So far several experts have looked at it. There was a software update, what could be the problem? Maybe the surface of the spiral snake heat exchanger of the indoor tank is small? the heat pump stops approximately every three days in the evening hours and must be completely disconnected from the power supply, after which it can only be restarted.
@@JumpermanTech Right I only asked because there was side note at the bottom of the video that you were checking this with the power on, so I thought maybe this particular unit needs to power on to check resistance.
Those M500 supcos are no good. The readings it labels are blatantly wrong. You need a megaohmeter with an actual reading on display. For about the same price as that Supco you can get a Klein ET600. Spot testing never gives a clear indication of poor insulation. A DAR test on windings will give a better idea of how good the insulation is. For further reading: IEEE 43-2000, Megger’s “A Stitch in Time”, Copeland 4-1294 Edit: Fluke also has a good article about IRT for compressors
I do want a megohmmeter that has an actual number reading on display. That Klein ET600 looks legit. What meters would you recommend as maybe good mid-range megohmmeter because some of the prices get ridiculous on the higher end. I need to look into those tests and articles. Thank you for the feedback & stay tuned for new videos every week🔧⚡️
@@JumpermanTech I’m personally a big fan of Klein’s meters due to giving the absolute best bang for your buck. There’s videos out there showing off how even cheap Chinese meggers are still able to give reasonably accurate readings compared to Fluke’s, but it always goes back to brand confidence. And I love the videos man, I do residential/light commercial so I never see anything as diverse as you do. You’re by far one of the best in the field HVAC/R channels right now. Salute.
Thank you Robert! The LG app is "LG HVAC SERVICE-BUSINESS". Definitely a great help. I'd even recommend to call tech support to confirm everything you found & if there could be any other potential causes for the issue the system is having. The testing documents I used in this video was emailed to me by tech support which is not found in the standard manual. They have all the secrets! Good luck & stay safe out there🔧⚡️
@@JumpermanTech Thank you much appreciated. Very complicated unit the LG Multi V. I had a slave and master unit. One time people were complaining about the temperature. All I had to do was clean the filters. These smart units either work very well or will give you headaches. I wish all calls was that simple lol.
@robertdavenport9095 You're very welcome. Definitely very complicated systems. I'm learning them myself. I agree. Man I need some easy service calls. Been getting difficult ones but thats what makes you grow💯
This is the "LG HVAC SERVICE-BUSINESS" app. Great to have when serving LG equipment. Also tech support has documents that the manuals provided don't have so give them a call & they'll email it to you. That's where I got the diagrams used in this Video. Stay tuned for new videos every week🔧⚡️
I can imagine this one is gonna be the worst compressor job ever. Man that freaking oil is way too close to where you’re gonna be brazing. Pay attention these units only have strainers so a little carbon will cause you so much headache. Good luck
In all my years of selling and installing LG MUTI V I never had a single compressor fail. I see videos of failure and think what was not done correctly on installation.
@@JuanTodoli yes, I seen those pipe connections did not want to badmouth anybody about their braze looking like a child’s building blocks first time attempt
VRF systems are a service techs blessing and curse at the same time. Get good at these boys and you’ll have steady work forever.

Would you want to sit in the rain all day messing with electronics ? The customer is fucked if its raining.
@@joshperez7731 Totally. Where I live it's always raining so I wonder how the techs deal with outdoor equipment all the time.

Diode test will confirm the board go/ no go
I just want to confirm that you're supposed to check ohms with the unit on or with the power disconnect engaged?
Anytime you're checking resistance (OHMS), the power must be off 👍 Thanks for watching & stay tuned for new videos every week🔧⚡️

I have to change the Compressor and Broad how crazy is that??? Thank you for the LG information my brother.
Lg with a bad compressor. No way!
That’s a joke just fyi
how would you even change this compressor, take out all the boards? looks like terrible servicability.
Your guess would be as good as mine on that condensing unit. Prob gotta tear it all down.
@maxlawton2754 Stay tuned for next week. Just changed the compressor today. Had to take down the whole control panel. Recorded the job. Terrible.
@@nebraskaman8247 Yup. Had to take down the whole control panel. These units are so smart that they are dumb😂 worst compressor changeout ever
