Interactive videos like this really drive home what you are trying to teach us Mike. Most TH-camrs just point and talk. The ability to follow along on the schematic and watch what you are doing reinforces what you are saying. Thank you so much for taking the time to edit and enhance your videos this way.
It is my great pleasure to do so. I try to help others in ways I was rarely helped when I needed it most. It's all about you guys for me because that's how it should be.
@@JerseyMikeHVAC , your methodology should be the standard for all instructional videos. There are many different ways of learning. I was the type of student that needed to see how a problem was solved, rather than just listen to the teachers lecturing. Thanks again for the great content.
I watch all of your videos Mike. First of all,I want to thank you for taking the time out to teach us all. Your presentations are spot on. I’ve learned so much from watching your videos. Please continue to make these very informative videos. I am totally locked in.
Awesome teaching Mike! Explaining about the sine waves makes it more sense why we the reading we get between 2 points. I’ll definitely be thinking about that from now on. Can’t wait for more teaching on wiring schematics.
Thank you. I've never really worked on mid or large sized equipment but these principles helped me diagnose a 50 ton RT unit once. Took me all day, but I got it. lol.
Thanks Mike for really making it easy to understand...just what I needed as I am learning how to read schematics in HVAC school... blessings to you...still following you from NJ 👍👍
🥇 material! Looking forward to watching the diag video and other multimeter application tutorials. The busy seasons are just around the corner. Do you also have videos on FAF diagnostics using a multimeter? Your sequence of operation video was what made me subscribe instantly. When or IF you decide to monetize.... take my money 💰!
I'm always busy, brother! Waiting for it to get SLOW so I can breathe. lol. Don't have any FAF videos right now, but I might do something on fresh air makeup fairly soon.
Mike if you work on walk in freezer and coolers can you please make some videos about it Love the way you explain everything ❤❤ Thank you for everything
Jersey mikes showing you how to make that extra lettuce! Slap on that oil and vinegar knowledge blend. A little experience. And a delicious little carreer you got!
Hey Mike I like the way how you explain the diagrams and circuitry for havc; I'm not HAVC guy I'm an electrician, I always ask by my self what can happens in an electric unit if I turn off the breaker of my heat, (I know both units "never" work at the same time) keeping ON the breaker for the outside compressor and calling for cooling at the thermostat assuming is summer time. Can you please give your best explanation about it, thank you. I'M from Jacksonville, Fl.
If the heat strips are on their own circuit then shutting the breaker off will not effect the AC functionality. But if the indoor unit is on one breaker, the outdoor unit will not get the 24v control signal to activate the contactor that turns the outdoor unit on. The 24 control voltage originates from a transformer inside the indoor unit.
Hi Mike how are you❤️ I got questions for pressuretro You said when system pressure build about .5psi pressuretro cut in setting then burner turn on. But when boiler not call for heating inside the boiler temperature and pressure will drop,will equalize to room temperature and 0psi. For example First time in winter,inside the boiler pressure drop and how to build the pressure to make .5 psi pressuretro contact close to cut in setting? I don’t get that.
The pressure doesn't need to build up to .5 for the burners to be cut in. It needs to be below .5 during a call for heat for the cut in. The differential plus the cut in determines the cut out pressure, so if the diff is set to 1 and the cut out .5, the boiler will cut out at 1.5 psi. Once it drops below .5 it will cut back in so long as there is still a call for heat.
Could u please explain more about why doesn’t need build pressure to .5 for cut in setting? What will be the normal position for pressuretro contact? Close or open when system is off mode?
@8joh58 It can be either open or closed when the system is not calling. The thermostat opens that whole circuit when it's not calling for heat so nothing will happen either way until the thermostat closes it on a call.
When thermostat is call for heat, electricity gonna be bypassed the pressuretro to turn on the burner? If not, how can electricity past through pressuretro since contact is open? Sorry Mike I don’t get it=(
No. The thermostat can never bypass the pressuretrol. The only time the thermostat can call for heat with the pressuretrol contacts open is when you have a head of steam on the boiler equal to cut in plus differential, which based on what I said earlier was 1.5 psi. At that point the boiler has pressure and is producing heat even with the burners off. Only when the pressure drops off to below the cut in does the contact re close and the boiler can fire up again. You need a call for heat and the pressuretrol closed for the boiler to fire up. Can't be one or the other. Always both. If the pressuretrol recloses but there is no longer a call for heat, boiler will not fire. If there is a call for heat but the pressure is above the pressuretrol cut out, boiler will not fire up then either.
You read 0 volts from L1 120 volts to L1 120 because they are at the same potential. There is no difference in potential, like you said in your most recent video. You get 240 volts from L1 to L2 because you are reading the full voltage across a 240-volt secondary coil from the transformer that supplies the house.

Mike your style of teaching is awesome. It’s nice to have someone explain things in detail. Thank you.

Love the way you break things down !!! Keep videos coming
Best tutorial ever Thank U Sir all the way from CA
You're the best Mike ,the way you explain schematics is so easy to understand thank you so much 🙏🙏🙏.
Now your teaching stuff no one else is thank you
Thank you! You never disappoint with your lessons, you’re the best!
Jersey mike you explain fundamentals, multimeters and schematics very well. .
Extremely helpful.. Thank you, Mike
You're welcome.
Brother, much respect, you make such practical and easy to follow instructional videos!! Please keep them coming, it is helping a lot of people 🩶🙏🏽
Excellent information and demonstration..many thanks
Your videos are so wonderfully done. Please keep up the good work.
Great videos although i work mostly on comercial mid sized heating equipment the basics you show are always helpful Thanks again
Thank you. I've never really worked on mid or large sized equipment but these principles helped me diagnose a 50 ton RT unit once. Took me all day, but I got it. lol.
Great job on all your videos very helpful… your the man!

Thank you, brother. Pay attention to schematics and wiring, it'll make your career a lot easier, promise.
Thank you for your help ,and also help others
Excellent explanation!! Thank you!!
Phenomenal job explaining this
Thank you For your time. Respect

@@JerseyMikeHVAC thank you for response, that clarify my question, very helpful.
My grandkids say that you have the voice for radio
Lol. I get that a lot.

Yeah. Phasing is 180 on the 240 between L1 and L2 while reading 0v across a closed switch is the same phase for no PD.
Shematics. Lol. That's a new one
Lol. I probably would have never caught that. Thanks.
Great video Mike, thank you
Thank you .
Great video. Thank you
