[@steveedelen3251]

Great vid Man. Really demystified these units for me. Really good info. Thanks. I will share it with my co Workers.

[@austrianpainterinhiding88]

This was an incredibly professional video. Thank you for the detailed explanations.

[@kennybassarath7168]

Great video Ken, thanks for sharing Your knowledge.

[@sxhernan]

Thanks Ken. Very thorough analysis of the system. Something that went unsaid is that you need to have an understanding of the system operation and the components in order to know how to troubleshoot them.

[@dannycalk8051]

I always keep spare contactors, fuses, and capacitors, to save the day. Great Video, very informative.

[@73elperro]

Excellent video,please keep making more!!

[@accdawsons]

thanks for the video. good stuff!! I wonder if you could raise diff.... to buy a little more time between the short cycling??

[@KevinPerez-ub9qg]

I appreciate the way you took your time and explained why you were doing things. Extremely informative for a beginner, thank you!

[@mel-hariri6124]

Dear Ken, I thoroughly enjoyed your educational video. I found it very informative and well thought through. Your approach to safety is commendable, the step by step processes of illumination during troubleshooting for each stage brilliant. Thank you so much, I'm better informed.

[@subbunathi2826]

Thank you sir your explained please irequested chiller control wiring Thank you

[@ОляП-д4х]

This is great And beauty technikal vidios! Super ! Good!!

[@boyetgarcia993]

Ken I realy like your vedeos! I hope you will also upload some Chiller Trouble shooting,Thanks I will wait for another Vedeo.

[@JLF678]

Great video instead of Chanel locks maybe a fuse puller would be a lot safer. Just throwing that out. Thank you though

[@emiliohuerta2658]

really liked your video, very detailed and you didn't stop just at you contact issue but went beyond and gave a more through tutorial. Thank you God bless you.

[@raymundodiaz4514]

Wow very well explained. Thanks for sharing your knowledge

[@shockwave8474]

Great video, should of locked out main breaker though

[@timcoleman2240]

Not necessary to lock out disconnect, as he was right by it and only working alone.

[@Prabhjot70]

Samuel Leighton if he locked 🔒 the breaker which is 2 feet away, his helper will piss his pants laughing 😂

[@robpeters5204]

Prabhjot Kalsi something called protocol.

[@robpeters5204]

Tim Coleman he did have a partner with him. Safety is best. Definitely.

[@mirkosekejatovski4069]

Nice. Thank u for sharing your knowledge. Stay well.

[@jsmith83400]

Well this is proper testing. I would suggest to clip ur meter to a wire so it’s not falling. The test are great. I always look at these videos to find quicker better ways to do troubleshooting.

[@jarrydee2799]

This is a great freaking video. Thank you for taking the time to do this. I know nothing about the pressure, but the electrical part was priceless.

[@arafatbaunto4068]

If only you have Thermal scanner can figure out easily the problem contactor

[@dionicioramirez1047]

I like the video.... The way you explained made easy to understand it....thanks a lot

[@motifes76]

Great tutorial!!

Thanks You Ken for sharing your knowledge.

[@raymondmartinez5079]

One of the best videos I have watched. Very informative.

[@juggie396]

very good tutorial awesome Thanks

[@hectorramos6975]

Excellent explanation. Thank you very very much for the time you spend with this video training, exceptional for some of us who do not work everyday on this but do maintenance.

[@deloct]

Thanks for sharing. I like the way you explain ed. Please keep the good work Sr.

[@garbo8962]

Would be nice if door opened higher so average guy does not have to bend to work on unit. As a 50 year industrial Sparky can gurantee that ALL IEC contactors are junk. A full size made in USA starter will last 5 times longer. Been on jobs where air compressors ran 24/7 with too many start & stops a hour. They were replacing cheap IEC contactors every 10 months. I installed full size USA starters and never had a problem next 5 years. Manufacturers always install the cheapest product. Last 100 HP fire pump that I PM'ed had IEC contactors. Could not believe that. I always opened up cover on fire pump starters to inspect the contacts along with voltage drop & IR scan. Can not open any IEC starters to inspect contacts.

[@KenTraining]

Great info, Thanks

[@donniepaulson4069]

Very detailed and done step by step. easy to fallow. thanks for the video

[@Albatroz50]

Thank you for the great job done and wantherstanding.

[@Melon-oc9lo]

Great video tutorial keep up with more electrical thanks

[@DG_Fabrication]

Great video thank you so much!

[@krakenwoodfloorservicemcma5975]

Voltage differential check across the fuse is a good one.

[@danielcole2667]

I miss doing this work. Thank you for letting me relive some of it.

[@electricaltyler5998]

could you have measured continuity between phases and ground to see if your winding were shorting instead of resistance measeurments? Thanks for the video good stuff

[@dwaynes965]

excellent video. Thank you.

[@Pyroethics]

thanks alot i learned a lot here Im a HVAC tech but only working on residential im planning on enhancing my knowledge on commercial units

[@alexsfit]

Pyro Ethics go on bro! there is more money in commercial that residential and less annoying customers.

[@ajaykadam7314]

great tutorial, just make sure you are audible.

[@josuereyes6219]

Great video no better way to learn than to actually see it

[@urjealousguy]

I really learned a lot, good video.

[@ZFB2]

One thorough explanation.

[@MrEchskech]

Great job, I've learn quite a bit

[@jeanfrancois7470]

Good job you're experienced

[@dwaynes965]

Just did troubleshooting on a lathe. 2 days. check everything all good no start. decided to go into main breaker box all good. turned on?off breaker few times. breaker shorted. found the problem.

[@wise1xo]

Hey thanks for going through this, you have explained the process very well.

[@erictriplett2386]

Hi Ken I would like to know where you got your thermal coupling clamp for your Fieldpiece multimeter like to have one of those part number maybe

[@BF-mu8dw]

Excellent work sir.

[@philliplee7703]

Ken, I really enjoy your video, I help me a lot to understand the power distribution coming into the panel, thank you very much. Keep up the good work

[@dougankrum3328]

there ARE insulated fuse pullers for this application....

[@Posichronic]

Real electricians never show up to a job with any tool they're not absolutely 100% sure they'll need. If they don't know what tools they need, they won't bring any, and then be bothered if you suggest maybe they should go get at least a meter and a screw driver because the healing touch doesn't seem to be cutting it today. Also, some synonyms for 'fuse pullers' includes 'flat head screw driver,' 'channel locks,' 'pliers,' 'my hands,' etc.. I guess if you get hung up on a fuse you thought was dead, the muscle spasm will cause you to yank it loose anyway, so it's no big deal.

[@abuzarmohdramli3666]

This troubleshoot are very helpful for me...newbie in HVAC maintainance...

[@Armedlegally]

You did a very good job in highlighting safety and checking the circuits .... However, if anyone is going to be inside a control box they need to put a lockout tag out in place. I can't express to everyone in the comments, maybe not you but to everyone it only takes 1 tenth of an amp to kill ya. And some pencil pushing upper management comes by complaining his AC isn't working and throws a switch that could mean your life.

[@hassanaljazaeri5436]

I’m new to the machine and I very appreciate these information it was so helpful

[@5eyes1294]

Hate to do it. 1: OSHA requires ARC Flash suit 2: You didn't lock out the disconnect. Lock, Tag, Try before you take off the PPE 3: You should be using a Megger to test the motor windings. "Your meter isn't capable of truly testing the insulation value" of the windings, phase to ground. Although, it is a good starting point. 4: The body of the compressor motor IS grounded. You mean, the windings in that motor are showing no "short to ground" or no lack of proper insulation (which your meter can't properly assess).

[@geofferyromany4634]

good video

[@MrGideon71]

Good video

[@rudytablada3342]

sorry what is brand of clamp tester thanks

[@KenTraining]

FieldPiece SC 77

[@stewartduncan7865]

EXCELLENT

[@localonly7264]

Glad I found u! I am a 2 yr HVAC Tech for major property manager co. in S.Fla. we have DX CRAC units in server rm. Will subscribe

[@garbo8962]

R they OSHA or UL approved fuse pullers? Did they same thing hundreds if times. Always had 3 sizes of fuse pullers but you can not carry everything especially climbing ladders to a roof. Best thing I saw was a large company kept a lot of tools, sockets & a meter licked up in roof elevator motor room.

[@4gizzle85]

Good job. You also could manually push contacts closed and check continuity, which is a littler faster than trying to land jumpers to close....just saying....good job though man ...very nice

[@ItzBeeTV]

Very good trouble shooting but poor show of Arc Flash protection. I'm not saying this to discriminate your video but for the new and up incomers. If an arc flash was to occur, assuming he is not wearing HRC Pants everything would burn except for his hands. Please be safe. Always wear your Arc Flash HRC Clothing and protective face shields if necessary.

[@philcanis-on3096]

Awesome video. Thank you!!!

[@raminsafikhani725]

solenoid valve problems usually divides to tow part one of them is coil(elcteric)problems wich is easiest part to remove by changing coil and another part is related to mechanical part or valve seat, which needs to be changed usually.what was that problem?

[@frad3965]

EXCELLENT PRESENTATION. PROBLEM, DIAGNOSTICS, AND PROBABLE CAUSES ARE CLEARLY EXPLAINED . THANK YOU

[@michaelmoreno7632]

Thank you for the video it was very helpful I've learned something new

[@chigbuezinne3298]

Good day sir, please where get good HVAC training. I from Nigeria.

[@bashirmohamed7982]

I liked the video

[@leehansen4750]

If you can get a contact kit from the motor starter manufacturer you can replace the bad contact, or all three to the motor since they draw the most current under load. Some contractors cost several hundred dollars & the contact kit is under $10.00 Great video! Thanks

[@krakenwoodfloorservicemcma5975]

I repaired locomotives for 12 years, we rebuilt a variety of contactors and relays. Fun work if the managers would leave you alone.

[@elmoncho72]

excellent video very clearly explained i gave you a thumbs up..keep up you are an excellent professional ..

[@711Ehsan]

Great video, very well explained. Learnt 2 major things, new use of the probe holder on the multimeter and the no ground on the compressor /phases bit. Thank you.

[@KenTraining]

Glad you liked it. :)

[@Reefertech]

Lol dude I never knew the probe holder on the Fieldpiece I’ll be using it from now on. Thanks man.

[@pibitos003]

Woowowowowoowowo. Thank you so much. For the video. For your time woowowwoowow very nice. Thank you master. God bless.
