How To Troubleshoot Low Voltage HVAC Problems With a Volt Meter. Tips and Tricks with Example Issue
Фильм және анимация
Here we go over some of the basics of how to trace down low voltage problems in an HVAC system. There are not many techs who are good at doing this but it is really not all that difficult. We go over some basics of how to get acquainted with a system initially and then go over some basics of actually tracing the wires and finding the source of the issue. This is not meant to be a completely comprehensive guide but if people want more videos like this let us know and we can make more. If you are a homeowner and you are watching this then I have to recommend calling an HVAC company but if you have a solid understanding of electricity and a good volt meter then the same principles apply to you. I cannot condone you troubleshooting these types of issues though so please don't.
I also go over why control boards are commonly misdiagnosed in this video.

Thank you so much for this video. Service tech apprentice and too scared to ask dumb questions and you just answered most of them
@3:03 "If you don't know... call someone who does" 😂👍
Please do more videos like this. I just retired from fixing computers. Nowadays I want to learn how to fix my own AC and gas furnace. Edit - New subs here.
Very informative and to the point video! I wish i had KZread when i started in the trade, went to school at night worked during the day, no body wanted to explain anything and went as far as saying they weren't there to teach anyone. Thanks for making the videos i know a lot of people will benefit from them and God wii reward you
We did Jonny dirty in this intro

One of you best vids yet. Thanks guys
Trying to become a new technician and do ac maintenance calls. I also am a lead installer. However I’m still learning I got thrown out into the wolves..I enjoyed this video. It made me understand to check continuity and volts from each point to see if there is a dead spot.. please make more for beginners thanks. Helped a lot

Wow, straight to the point and good to know. Will incorporate this technique next trouble call.

Love troubleshooting videos more please
Loved the video man ! I think you did a great job explaining it. Been in this trade for a year and I'd say my weak point is electrical diagnosing but this helped clear some things up for me

Main advice I can give you is to not let the system win. Take every call like a challenge and if you can't figure it out you lost that one. Sometimes calling for help is necessary but before calling do everything you can to avoid calling someone. It will help you on the next call. Thanks for watching:)
dude this video was so awesome and helpful... more of these please! liked and suscribed.

Great content, new subscriber
Like how you went through and explained the way yoy find a short.

Future video my friend. Shorts are a whole different thing and in my opinion are must easier to get the hang of than troubleshooting in general. Really not all that hard to figure out. You can call me on the number in our bio if you need help figuring out a short
best advice for new techs is to learn schematics inside and out and the legend!!! so you can identify your loads great video red showing how to hop scotch and identify components then you get bored and move over to low temp lol like i did i do both
Just a tip. The method of hopping around with ur meter is called the "hopscotch method"

Please do a video for mini split systems

I will do some mini split videos but I think I need to be on them when they are broken as they are harder to explain without a broken system
And my instructor said don’t wear shorts

Could you do a video on troubleshooting carrier Mini splits
@SurfBrosHVAC

Almost all mini splits are the same to troubleshoot. I do plan on making some videos on how to troubleshoot them.
I’m new to the trade and I have so many questions . But it’s really hard to understand the electrical . Can you simply explain how a hot wire and common wire blow up some of the components?

Really like the video, but can you do a white board explanation with a few lines just showing what you mean by certain things. Because we couldnt see what you were testing so very difficult to visualize. Example, the relay not allowing power to the transformer, or where did you find the common? To then use the other lead to check for low voltage? What points are you looking to find 24 volts in the low voltage system with one lead on common? Your great, but if you are looking to help make other techs better, some white board breakdowns would help us better understand what you are relaying.

@@SurfBrosHVAC Oh, I get it! But since you have that fancy white board... "story board" you A-B-C-D etc path, what visual tells the story you're narrating? Close shot? Wide shot? POV? It doesn't have to be perfect, it just can't be confusing. It's okay to pre-script the important parts, you're trying to do a lot all at once - working on a system, teaching trouble shooting, and making a video. As you develop a work flow it will get easier but start your shoots with an outline/punch list and a couple paragraphs of specific language to make the video part easier.
