How To Use Diagrams to Learn, Diagnose & Earn More

Guaranteed to advance the careers of new HVAC Techs.

Great video Jersey Mike. I hope you continue with more videos progressively building on what we have learned here.

[@turnedearthdesign8678]

Another thing to remember so you don't have to memorize what type of switch comes in what position, is that all safety switches are wired normally closed. They monitor the systems and open when there is an issue

[@joebanks174]

More videos like this. Maybe progressively more complicated videos. Also I would have liked to see examination of the circuit powering the start winding. Good stuff

[@LouisS-cs7bh]

I think you hit a nerve!! This is a topic I think we all could improve on and gather additional knowledge. Can’t wait for the next one!! Appreciate the effort you put into these videos. It takes time and thought on how to present and prepare so your audience can follow and understand what you’re explaining. Excellent!!

[@JerseyMikeHVAC]

Thank you!

[@deanmartin1966]

Great video. Thanks for sharing.

[@hurcklynbrown2630]

Very informative

[@trevmint5615]

Great video. Can't wait for part two

[@elgkas9928]

Mike, every skill set starts with a foundation. This video is a great base for the foundation and I look forward to the next video. Schematics can be very overwhelming. I have printed out schematics and used color coded markers to make the circuits stand out. It makes it easier for me to understand how each circuit interacts with the others.

[@JerseyMikeHVAC]

Yes, Sir. A foundation video was exactly what I was aiming for. Way too big of a subject to tackle in one video. I used to use markers too, that's where I got the idea for using electricity graphics over the schematics in some of my vids. 👍

[@HD-pc4id]

Great video

[@brianmcdermott2430]

Great info.

[@JackGore]

This is really a great video open my eyes to so many things that I’ve been looking at that. I didn’t understand you have a gift and the way you speak and deliver this information and I can’t imagine how much time you put into putting this together. thank you keep up the good work.

[@JerseyMikeHVAC]

Thank you. Only really took me about 10 hours total to put this together. It's finding 10 hours of free time to do it that is can often take days or weeks to find sometimes! Just glad it's helping people out. That's the goal.

[@miguelrojas3394]

Thanks Mike ,I really appreciate you sharing this videos.👌👏🙏

[@stevencossaboon3237]

Great video Mike. Thank you.

[@obakpo88]

Thanks, very informative.

[@yanslabrada8904]

great video, thanks you !!

[@jeanlawson9133]

Really good video...

[@phillipjoy1305]

Great video 😊

[@borshardsd]

Definitely a needed video. As a field tech, what I need from you, get ready to laugh, ***we need you to tell us how to read the schematic that disappeared or is half missing on the old equipment I have to work on*** lol Great job and keep it up

[@JerseyMikeHVAC]

Yeah pretty common issue. I take down the model number of the unit and check this link for manuals: www.manualslib.com/ I'll often find the schematics there. If not, try a general google search with model number and "manual" in the search terms.

[@borshardsd]

@JerseyMikeHVAC dang brother! Thank you for the comment. I agree there are ways to find the info =D just wanted to share a smile.

[@tommajor4995]

Great explanation!

[@JayPatel-j9]

Thanks a lot ..

[@harrycastro592]

Thanks master

[@jeanlawson9133]

Been having issues with the heating side of my HVAC heat pump.... Located the issue my HVAC guy bypassed the circuit board and I was looking at the Schematic and it was dirty so I took my dry hand made one swipe across the schematic and it disappeared 😮....So I still need to acquire one....I know it sounds like the dog ate my homework....I want put it back correctly. I have acquired a new circuit board. ,heat strips,blower , all check out well I am running Air as we speak... issue was blowing 3 amp fuse, was transformer. Haven't checked heat since fixing everything wanted schematic to correct before I went further. The HVAC guy has connected 3 or so wires to one going in towards compressor all taped together with a lot of electrical tape... That is what I want to fix. Because it had only one heat strip working... Your video are awesome by the way, that's how I got this far. From not😢 working at all. I spoke out of turn... I simply need a schematic, Where to get one... HELP

[@JerseyMikeHVAC]

Glad my vids are helping you. I get a lot of manuals I'm looking for right here: www.manualslib.com/

[@wim0104]

thank you!

[@marcolanza5132]

You are an amazing teacher!! Great video!

[@JerseyMikeHVAC]

Thank you so much

[@robertmunguia250]

Great video! When the line traces back to run winding, confusing to see why wouldn’t it go to the start winding? It goes to common.

[@JerseyMikeHVAC]

To be honest, I never actually checked with a mutimeter to see if voltage is present at the T2 terminal with the contact open to confirm voltage is present through the full path of the run and common windings, but in theory some kind of voltage should be detected there. Maybe not 120 due to resistance, but something. The reason the motor doesn't run is because you need a full circuit to provide the current that actually creates the magnetic field that propels the motor. Voltage alone doesn't make the motor run.

[@robertmunguia250]

@@JerseyMikeHVAC so then the easiest path would be to go to common?

[@robertmunguia250]

Also I have a slant coil (Carrier) debating whether to clean it in the unit itself or remove it. Leaking water condensation too much on bottom.

[@JerseyMikeHVAC]

@@robertmunguia250 I would try inside the unit itself first. it's a lot of work to remove it, braze, vac, etc.

[@JP-sd2cw]

What confuses me is you can have 24v on your coil, but a safety is open on the neutral and it still won’t run…?

[@JerseyMikeHVAC]

If you look at the low voltage ladder diagram, you'll see the safeties are wired on Y which is the 24v side, so the voltage doesn't actually reach the coil on an open switch. But even if they were on the com, you need an electrical current to create the magnetic field that pulls the contactor in. You don't have current on an open circuit. Think of it like a water wheel. You can have one sitting in water but if the water isn't moving the wheel won't rotate.

[@ernestodiaz76]

Know can we talk about inverters boards and how to troubleshoot

[@borshardsd]

@@ernestodiaz76 know, not know. Lolol

[@JerseyMikeHVAC]

I've actually been trying to find a way to tackle this topic for a while now, which can be a little tough. You kind of have to zero in on specific systems to tackle diagnostics because manufacturers use different methods to control these inverter circuits. On the flip side, a broader concept overview isn't going to help much with diagnostic procedures for the same reason. So basically, I'm going to have to get into this with multiple videos, multiple systems and specialized testing tools at some point. But I definitely intend to do it.

[@randomyoutuber6992]

Too easy, next lesson
