Residential Low Voltage HVAC Troubleshooting Class P2

Very nice video and help full for new learner students, it's not big mistake common person can find out what is the fault into the electricity hvac technician need understand interlock wiring, electronic devices microprocessor plc and DC 12 volts sefty components, ducked ac unit is very common can easily find out the problem

Way to much going on to understand wish someone would break it down in an order by themselves it would be much easier to understand

Starting my hvac career soon. I'm so excited that I'm up at 12am watching this!

it's like herding cats 😂

Love the lesson
The teachers attitude is aas though

Good teachers whith a los oficiales patience god bless you guys

When I makes some bucks benefiting off of y'all's lessons and wisdom.... I'll give back. Thanks y'all! .
Thanks 🙏
And
Much respect!
👊!

I would love to work for this company! Del-air did me dirty! Most of the techs are getting OJT and don't know barely any thing!

Teacher yells to much they need hand on

I really like the info in this video but I think if you edited it to show one in its entirety and then the other it would be more helpful to us new guys. It gets a little confusing when you talk about doing something and then it switches to another system where they’re doing something else. I needed the info from the unit Brian was working on and it’s harder to digest the info because you guys talk about what to do then switch to the other unit so I had to watch it several times

Great demo for trouble shooting for new folks and a refresher for higher level tech. Thanks for a great show and tell real problem examples.

I have the short pro tool and burned up a couple transformers while using it when the short is at the condenser

Ha, his mic has an open @ the end..😉
Awesome instructor you are Bryan. I am forwarding these to my trainee . Keep up your great efforts and you will turn green techs into mean techs.
Never stop learning people. 👍🏼👍🏼.

Ooo . Love diagnosing lab faults.. kill power, ohm out contactor coil, then each R, G, BL, YL, WHT to common. Contactor coil should read 12 to 17 ohms ..any lower can draw more current than is supplied resulting in an open fuse.
Tech may find a rub thru cable on ductwork or too many loads on the low volt supply..ie zoning control, 4way reversing valve coil, liquid solenoid, even a faulty tstat circuit itself, or faulty sequencer delay heater if used.

“What human error can cause this to not work?” Lol!

You can spot the installer with all the mastic on his pants 🤣

check in from Tampa Florida Thanks

Thank you for another great video

Ideal stripmaster automatic stripper. $25 TO $30 KLEIN MAKES ONE TOO

Instructor tells the students to put on safety glasses, but doesn't put any on himself. 😉

I would have left the sheetrock off so that it could air out and dry and told the apartment manager to have it patched back up after it dries.

I really wanna get into reefer units but there’s no school for that.

Thank you for having these video. 3 and half weeks from graduation and being certified. This is very helpful for upcoming finals. 😊 ty ty ty. Any tips for the interview I'll go for after I finish school.

The training is rewarding I love every part of it. The install Crew becomes acquainted and it just brings good vibes.

I sincerely appreciate the genuine aspect of your teaching

The camera person must be a fan of Pulp Fiction the way he/she jumps back and forth from one scene to the other.

I will usually use my razor gently around the other jacket to expose the rope pull it down from there and cut above where I scored with my razor

Crocs n socks !? I’da Been sent home off rip

Being retired Telecom Dept from a Famous Railroad, I might add in the Fall Rats start looking for nesting material, and they go to cables, resulting in shorted or open wires in the Fall!

great video, please do more combining sequence of operation, thanks

Every one need safety glasses.

YOU ARE THE BEST

Bosses way is the ONLY way ...ALWAYS

Awesome job. Start at the braindead basics. Knowing this when troubleshooting and you get twisted you come back to basics and start again and verify what is and what is not. Well done instructor. There is real skill in problem solving. Think it through don't be one of the brain dead part swappers. Part swapping only as a last resort to confirm our theory.

Thank you so much...I'm new with HVAC-R and really learning a lot from your videos

What I did is go outside and take the cover off the contactor at the condenser. I would check for 24 volts across the contactor if it was not running. If it showed voltage and not pulled in replace the contactor. Then if pulled in and not running check for voltage across the contacts. If no voltage then check the breaker and the fuses. If no 24 v on the contactor then check the thermostat. If thermostat is set to be calling the check red to blue for 24 volts. If no 24 volts check the tx fuse...if good then check the tx and if no 24 volts at rx replace it. This always worked for me.

Idk how Brian keeps his cool with this group of students. Half look like they just hit a blunt and don't even know where they are. I would give my left nut to work for a company to invest this much in me and teach me.

If you didn't bleed you didn't work

How to calculate LRA to amper.

Now just try troubleshooting these furnaces when it’s 150
Degrees in the attic lol

I went to an hands on HVAC school. Taken them apart and put back together over n over again. But also had power point lessons as well. I was always taught to look at what color wire is connect to your R,C,G,W,Y etc. inside the AHU and behind the t-stat because your green wire may not always hooked up to G terminal. Take a picture of the wires behind thermostat so you don’t forget when your at the AHU. But overall great informative information. Now for things for the instructors you must lead by example and if your telling students to wear safety glasses. You as an instructor should also be wearing safety glasses as well.

Good low voltage tutorial i have a lot of getting a new trouble shooting about 24 voltage open wire and how to do this to resolve the problem. Thanks you sir. God bless you sir

Is continuity and ohms the same? I thought the beeping sound was continuity

Man great job. Love the question about common. This is troubleshooting.

Enjoyed the video. However, I believe it would be more informative and easier to follow the troubleshooting by the techs to run through each of the scenarios from start to finish before moving on. The presentation made it more difficult to follow what is going on. ( I am a big fan of your videos)
