Diagnosing a Locked Compressor 3D

- In this HVAC training video, we show the process of diagnosing a locked compressor in a 3D animation. A "locked" compressor is what we commonly call a compressor that fails to start and goes off on overload.
Topics covered include:
The internal components of a compressor
Refrigerant-cooled compressors
What causes a compressor to lock up
Operational overheating vs. overheated windings
Diagnostic steps
Thoroughly inspecting electrical components
Checking voltage
Verifying proper wiring
Testing the run capacitor
Using hard start kits to attempt to unlock compressors
The operation of potential relays and start capacitors
Soft start vs hard start compressor starting
Even if adding a hard start gets the compressor running again, there may still be an underlying issue that initially caused it to lock up. Proper diagnosis and communication with the customer is key. This 3D animation provides HVAC technicians critical knowledge for troubleshooting locked compressors in the field.

Love all your videos, You guys do amazing work but the 3D videos are my favorite. Thank you for the knowledge
As a second year technician, it blows my mind that I've access to this incredible training material for free!
I'm a father of 4 at 33 yrs of age. Starting school January for HVAC. Tired of being broke with dead end jobs and need a career. I'm very nervous, but I will be using this channel for help. These videos help a ton! Very much appreciated!!
wish I had these videos 12 years ago!
Very well done animations, nice.
Always always always appreciate the amazing videos
I still have my hammer. When they don’t want to start

Works every time😊
😂😂😂 100%
😂😂😂
Agreed. Always got the dead blow on standby
Nice. Thank you for this I just started as a hvac helper trainee and this video help a lot.
ITS GRAT VIDEO FOR TECHNICIANS
Good class I don’t know nothing but I’m learning thanks
Tremendous educational tool, thank you.
Great video! Amazing work
Great video. Thanks for sharing.
As usual great content and explanations. I appreciate your commitment to improving the industry and especially training .when I came in the trade this kind of stuff wasn’t available.
I really love this 3D videos for better understanding thanks brian.💯👌
Great Video. Thank you for sharing
Can you please 🙏 illustrate what happens internally when the system is contaminated.
Fantastic video! Great job!
Great video 😊
Thank you from Vietnammes HVAC
Absolutely top shelf video- well done, guys!
I learned so many new details from this. The internal compressor views to illustrate the various mechanisms used is fantastic- making it easy to understand.
Great as always
Omg beautiful.
Thank you very much good job
Thank you for the video, help me a lot.👍😎
Nice method
nice video
Amzing🎉🎉🎉
Why newer scroll compressors tend do seize up more? 30 years old piston compressors still going strong… 5 years old scroll cant even handle 1lb overcharge?

Video it for us.
Hey everyone I have a question. I worked HVAC a few years ago for 6 months on a small crew that basically teamed up all together for most jobs doing the full scope of work. Now I've got a new job in the industry on a small crew and it seems my job will mostly be doing preventative maintenance all day every day, do you guys think it's worth sticking it out on a crew just doing the same thing on repeat all day every day? Seems like a very slow way to learn to me.
You will learn to identify which parts wear out faster and when to replace them. I worked at a food manufacturing facility both in the engine room and on production which was wandering the floor and being there for catastrophic failures or adjustments the operators couldn't do. Doing PM's seems the worst and if you are used to excitement can be boring but if you still have a bunch of years to go it can be a learning experience as long as they let you. Also don't wear a watch!
If your plan is to be a technician or mechanic then it is definitely worth it. It's also important knowing how to do retrofit change outs and new construction installation for service techs and mechanics. If you don't know how to or are unwilling to do the dirty boring stuff then it'll be harder to advance your career/position. Besides, if you pay attention and can catch issues before they become expensive problems during a "regular maintenance", people remember the guy who saved the company money. Also, if you come across a component or process you dont understand during a maintenance, research it on your time off. Google, co-workers, bosses and channels like this one are a tremendous source of knowledge. Use them. And remember, RTFM. Read The F-ing Manual.😂Sorry for the long reply. Best of luck.
If you are young and keen to learn, my advice is stick it out for a while. It takes time to come across all the many different problems you will undoubtedly encounter. To be exposed to them and learn from them is invaluable. Knowledge can be created but not often forgotten. Good luck.
@@stuartdixon747 I decided to leave. The way they diagnosed was overly simple. Feel the air with hand for indoor and outdoor units, look for even condensation across coils, feel for beer can cold, listen for anything out of the ordinary. We were only really there to confirm the machines were running and clean the coils + drain pan tab. I found an office that hadn't gotten cool like the others after plenty of time running. My superior put it in test mode which got it to feel cold and he said "see it works" with no further testing. Maybe I'm wrong but I don't think that's a good approach to learning
Why the bubble gum club music? Other than that, great!

thank you for your comment and apologies for the mistake!
Had this problem recently. Ohm check ok comp not grounded but was still humming and drawing 70amps. Mechanical failure locked rotor amps.
