You no it burns me when people give a thumbs down. It takes a lot to make a video and it takes a good mechanic willing to share knoledge on the trade. And the people that give thumbs down well let's see what you can do ? This was a great video thanks a lot and it's a big thumbs up from me
Thanks CB👍👍🍺🍺 HELL HERE IS SOME 🍨🍦 TO. I appreciate that! I'm not everyone's cup of tea, and I'm not perfect so maybe they didn't like something I did. It's life 😁
That was great Rick! They never taught us that little trick in school! NICE!!! That got written down! We'll play with that one for a while every chance I get for the practice! Practice makes permanent! Thanks for that excellent tip!!!
Me either, I seen it on a Steven Rardon video 👍👍
Detective work! Spoken like a true professional. I love it when I have to get my Sherlock on...
🤣🤣 Your exactly right Morgan 👍👍. I appreciate the view and the feedback! 🤜🤛
I had a run capacitor issue like that last year on a brand new Trane. Installed an OEM capacitor that bench tested perfectly and showed under capacitance while running. I spoke with a bunch of engineers and nobody could give me a reason. Just a note that I did test it with three different meters and get the same results. I guess that’s why they call electricity a theory.
True that 👍👍
Yeah, Amprobe stuff is made by the Brymen company in Taiwan. They also rebrand their instruments in the United States under the Greenlee name. And they are a little slow registering amp readings. The Amprobe 300 series with the "amp tip" function produce very accurate amp readings, especially in the lower ranges.
And I also believe that our "customer questioning" techniques are one of the most powerful diagnostic tools we can have in our bag. Done correctly, with the proper questions asked, you can get them to tell you an awful lot about the problem. Things they didn't even realize they knew. It can save you valuable time out in the field and save you wasted trips down the Rabbit Hole. 😎👍
Bingo 👍👍 Just asking the correct questions the correct way 😁. Thanks 4 watching 🍺🍺
We are technicians and detectives.
Need the outside air damper controlled by CO2 sensor. That way it’ll stay closed most of the time. Great vid
We have some locations that have that but they are a lot more money. there's a lot of people that don't want to spend any money around here so unless it's mandated by the state it doesn't usually happen. Thanks for watching I appreciate it 👍👍
Great ☺️ ☺️ video keep up the good work
Love the AP nav51
Thanks 4 checking out the video and the feedback 👍👍
How nice to have lights above the air handlers.
That's a fairly new building, it's a good place to maintenance. We do all the reach in and walk in refrigeration there in addition to the HVAC.
Enjoyed watching !
Thanks Ted! I appreciate hearing that 👍👍
Great job and video
Thanks Donnie 👍👍
Good one Rick
I appreciate the view Greg 👍👍
Also, I love using the power factor feature on my fieldpiece sc680. I enjoy your vids man
Thanks Ashton that's very nice of you 👍👍I appreciate you taking the time to watch and comment!
HVACR Survival absolutely, I give credit where it’s due. From one tech to another. Be safe out there
Good thing you dampered that outside air, I'm not sure where your from but in GA on our commercial units the max OA we allow us 30% do to the humidity issues. That seems to work best and it is by the engineer's specs so good job on noticing that. Personally I love my fluke 87 but is very limited on what they can do
Thanks for checking it out 👍👍. A lot of times the fresh air damper is there to pass inspection then gets closed 😏. The 87v has proven to be good at bench work in electronics repair and industrial work. I'm curious what is it missing that you would need?
Ohio
HVACR Survival it's not shock proof lol dropped it the other day in the case and the screen is only half working. That's operator error problem though
It might be just the rubber ribbon cable that goes to the LCD screen. You can pick those up on eBay pretty cheap ?
HVACR Survival thanks I'll take it apart and see
Great video bro 💪
Thanks for checking it out 👍👍I appreciate the feedback!
I really liked the capacitor under load math. Gotta say i did not know that. Thanks for that! I would have checked amps on the contactor and voltage there. Hate the . Oh now its working calls. Same hoses for the same reason. Love it thanks for that validation. Also.. wait you just said it was clean. Nevermind haha btw thanks for making me watch work on my eveng. What is my dang problem!?
🤣 I'm glad you liked it 👍👍🍺🍺
Another great video 👍
Thanks man 👍👍
Great video
Thanks Will👍👍
Welcome! I'm 8yrs in and still see units that quit and then work fine while I'm there, that being said you just gave e me a few pointers to check on. Your vids are awesome and cant wait for more! Be safe out there!
@@willhvac Awesome to hear man! Thanks for watching and you be safe as well.
If you don't mind, I was curious about something. I think all these devices are On-Of compressors, is there any reason they are not inverters?
Because of cost, no one wants to spend anymore money than they must. OR Maliyet nedeniyle, hiç kimse olması gerekenden daha fazla para harcamak istemez.
@@HVACRSurvival Yes I got it, you are right. I really like the packet channel systems, which are common in your country, of course, with the structure of these houses. Our single-storey buildings are made of reinforced concrete. I also saw that in your country there is a power cut-out to cut the supply voltage near or on outdoor units. This is definitely a well thought out standard. In our country, it happens indoors far from the energy breaker, which is difficult during maintenance and repair. I am very curious about the devices and the working system of people in different countries due to some differences I saw at first sight. You work alone, your equipment is very high quality and professionally this is very nice.
Also thank you very much for writing in Turkish. This made me very happy 🙏🙏 nice gesture
@@HVACRSurvival Google translates a little differently, cannot convey what I think. Don't get me wrong, I'm sorry.
I was curious what it was until Google told me 😁👍👍, maybe someday Google can do conversion of language on the fly as we speak.
It's fine. Just like me using the word (on the fly) doesn't mean a fly but means automatically 👍👍
Good 1 Slick Rick ...Lol ...
Thanks fast Eddy 🤣🤛
@@HVACRSurvival Lol ...
The fuse adapter on the top center fuse is split open
I'll have to rewatch the video.
When you checked the amps on the capacitor, which wire do you know to check when doing the 2652 math? Run, start etc.
The wire feeding the start winding from the capacitor. 👍👍 Thanks 4 watching!
@@HVACRSurvival thank you. I had to watch this video twice. I learned something new. Never thought to check a capacitor while running.
Yea it was something I learned later in the field not to long ago. Lol. Just be careful 😁 it bites harder than 120v per leg does.
Learning to check caps while under load has saved me a lot of headache and really makes the difference
Your a great tech👍
I'm just like everyone else. Im just trying to make this"work" look fun 😁
From your POV, what is the the hardest things to learn and do in the hvac field???
Depends what part of the field your talking, I mean there is something new to learn everyday. For me I would say because I do so many different things it makes it hard to remember it all.
Nice one , Rick ! I was waiting for as new video from you and there it is !
Btw , do you remember where that formula to calculate the micro farads come from ?
I remember learning one in trade school but for the life of me I cannot find it again , I even looked for it on the web but I couldn't find the one I was taught ... Maybe because we use 230-240 V for single phase , I dunno .
Hope all is well , Rick , hopefully see you on another live stream innit !
I would search for "checking a capacitor under load." You should find something that way. I believe I did once before. The videos seem to always get screwed up by something going wrong. This one's been sitting for awhile so I finally edited it. I appreciate the comment Mr. Archer 👍👍
@@HVACRSurvival I look forward to your videos , sir .
I always learn something from them , brilliant work indeed 👍.
Here is a great article from Bryan www.hvacrschool.com/testing-run-capacitors-smart-easy-way/
/wonders if the maintenance visit in March added some gas to the system, which meant it was overcharged come the heat of the summer months...
I did the maintenance in March but didn't add anything. Our agreement technically says check everything but the pressures, but I usually do for this very reason. But March would have been too cold for accurate measurements in Ohio.
Probably, I try not to adjust refrigerant charges during the cooler months unless it's a known leaker.
@@scrambler350 I feel the same way, its easy to over charge them in the colder ambient temps. Far as known issues, I don't believe we have had many problems with the HVAC here.
HVAC whisperer
😁👍👍
Detective Rick solves another capper
👍👍I can't say" big picture"🤣 So I'm going to build my case 😁. Thanks 4 checking it out and the feedback.
This is weird call. Sometimes weird things happen.
Yea your correct. Watching the video several times over while cutting it down, I decided it defiantly was mainly the overcharge issue. They never called back.
Could u pls give us that formula for capacitors again in the comments section
Start Winding Amps x 2,652 ÷ capacitor voltage = microfarads.
Thank U for the Prompt reply.God Bless
Would you think that the Unit might be shy on some Btu’s for the space it’s trying too cool
True, 10 Tons might be a little light. But they said it normally was able to keep the temperature? This call was from 1.5 months ago and they haven't called back far as I know. Thanks for watching!
✅
Yep! China made USA price. People need to be more aware of this and not purchase it... Sad...
I like the insulated hard pipe! Great job!!
Thanks Phill 👍👍 I appreciate the view and the feedback.
@@HVACRSurvival of course! It's very rare to see HVAC equipment installed correctly for maximum efficiency. I know what it's like to do the job correctly..
I'd say you need to read in the hundredths scale to accurately test those small caps and motors but even then I don't fully trust the readings
I've read that. 👍👍 I don't do this test very often but here's a good example of when it does make a difference.
That amprobe clamp meter is from the fluke company.
Yep, its there second class citizen. They did not stock the NAV-52 in Washington State. I had to wait nearly 20 plus days for a warranty meter.
My main meter is a 376 fc
I have that one to, it's a great meter 👍👍👍. Fluke gave it to me because I had to send back the Amprobe twice for poor battery life and issues reading freq drives.(that was some great customer service that day) now here is the funny part... I'm OCD about scratches so it sleeps in the toolbox until it's summoned. 🤣🤣🤣
👍
Thanks John!
👍👍👍
I appreciate the view!
#120 thumbs up
Thanks Steve 🤜🤛👍👍
More time spent on advertising on amp-clam meter.
Yea, I got on a rant and forgot to cut some of it out 😏. I'm a tool nut and it shows
Great video
Thanks for the feedback Juan👍👍
