hvac:no cooling, low voltage short

[@RobHVAC]

Great job Steve. Great troubleshooting. I love my little popper for low voltage shorts. Comes in real handy.

[@kurtc3803]

I liked the honesty about the heat and other irritations when working on HVAC

[@tenkara1309]

I could tell that was a frustrating and miserable job, thanks for taking time to film it. This video certainly helped me out. next level

[@Ebon_Wolf]

I'm glad I found this channel. I like how you explain things and its nice to see the stuff I'm learning about in action. I'm going to school for HVAC right now. I think I watched about 15 videos yesterday haha.

[@stevenlavimoniere]

well hope you can pick up a few pointers ,thanks for watching

[@jhhvacplumbing1944]

Great job Steve , I know that attic was hot and it gets frustrating . I need to find one of those poppers , that's a great tool! Nice house for not staying there all the time.

[@stevenlavimoniere]

its called the little popper they have 3 and 5 amp ones

[@jhhvacplumbing1944]

Yeah haven't seen them in any supply houses around me , going to find it online somewhere . Thanks

[@jhhvacplumbing1944]

Oh and those in line fuse set up , is that something u made or u bought it ?

[@stevenlavimoniere]

its a automotive fuse set up you can just use spade connectors also

[@jhhvacplumbing1944]

Thanks for the reply and info again Steve

[@ajrvisuals]

I'm currently going to school for HVAC and I must say your video was very helpful!

[@mustafaozcan4020]

I have a contactor receiving 24V but it doesn't close. I changed the contactor but still doesn't close. I guess there is somewhere short or backfeeding on the low voltage.. I don't know what to do.. What should I do? thanks.

[@1973ktully]

The fuse popper is a great idea. It saved you time and money. I need to get one.

[@qualudor1654]

Kevin Tully Marine stores like West Marine usually have them.

[@edmarsh1965]

Steve, it always amazing every time, I watch one of your videos and you find the problem on the job..The ice cream truck out side always ,has the part for the job..Does the truck every run out of parts!!!!! MAMA!!!!!your gone to have to give it the OLD GUNDY!!!MAMA!!!!!

[@danthesupercontractorhvac9690]

Actually had the same problem a few days ago, the only difference was the mouse was still there. He chewed the high-voltage 120 volt line, cooked him LOL

[@stevenlavimoniere]

Daniel Grenon lol death sentance

[@Brad1237202]

Thanks for sharing Steven! Like Rob HVAC, I use a mini inline 2 amp breaker for finding shorts. The best $10 the hospital ever spent!

[@stevenlavimoniere]

shorts can be a problem finding i have found the compresser contactor is offen to blame

[@Kaibil66]

Excellent video.....very professional performance.

[@stevenlavimoniere]

thanks kaibil for the comment

[@myronsmith2114]

Your 24volts is your load side of the transformer

[@adamrspears1981]

"Fuckin' mowse has bin chewin' ahn my wye-yuhs!......bitch!" -Lovin it Steve! Great vid😃

[@PBS-nm1uu]

this is the best video from you i have seen. thanks

[@chadwickhosier6125]

Good stuff man. I'm about to hit the auto parts store to stock up on the fuse holders. Smart. Thanks Chad

[@stevenlavimoniere]

Chadwick Hosier thanks for commenting

[@airecraft1]

I saw a first form me yesterday. Someone had two transformers on a Hvac system both tied to r and c on the control board the thermostat didn't have an rc rh . The heat and air were running simultaneously

[@stevenlavimoniere]

wow do you change the tstat??

[@airecraft1]

Got rid of the second transformer it wouldn't matter what kind of stat the way it was wired they were both paralleled on the same r and c Fed from separate power feeds

[@russturner6875]

good video Steve,, those hot attics can be a bummer, I usually sweat so bad I can't see through my glasses

[@harrydickson4575]

Good job on the diagnosis Steve !! must love the mice its job security lol great job

[@stevenlavimoniere]

bam mice......... what a bitch

[@harrydickson4575]

Yes they are!!!!!

[@hvacman77]

Nice video. I use the multi voltage transformer with the built in reset they are nice. I had a call the other day gas furnace blower was tripping breaker replaced motor found control board only putting out 92 volts. First one I seen do that

[@stevenlavimoniere]

nothing suprices me any thing is possable

[@halleluYah79]

love your videos man. learn a lot. thank you and keep them coming.

[@stevenlavimoniere]

i sniknej thanks for the support

[@over50txtech8]

Nice video Steven, that little popper will pay for itself in no time at all. Keep up the good work. Ray

[@stevenlavimoniere]

the little popper is a handy tool to have

[@arnoldnavarro21]

so the mice chewed the wire cousing the transfomer to blow? just splice the wire and replace the transformer. whats the connection with those two?

[@apfelsnutz]

Kudos again Steve... you're the man !!!Ron

[@nicholasceea4109]

Nice troubleshooting Steve. I like that fuseholder.

[@stevenlavimoniere]

Nicholas CeeA well save the transformer from burning up again

[@justincoulam6965]

"its fuckin hot up here man this fuckin attic killin me up here" My thought process every attic im in scramblin w a part

[@monterrozacesar5]

That wasn't easy..!!! But you did it again. Good job 👏🏻

[@joshuaf1475]

Awesome video. Keep the service and install videos coming!

[@stevenlavimoniere]

sure will

[@seanmcdermott416]

Nice Steve . I'll use that fuse set up next time I'm changing out a contactor or a step down .

[@Jeepjones85]

I worked on one back in the summer where the wired the 120v hot wire for the transformer through a ss1 ! I had one of those voltage detectors and noticed the wires were hot at the float lol crazy mess could have caught on fire 🔥

[@marcelinohernandez6492]

good job men. tnks for give us yours videos.

[@stevenlavimoniere]

+Marcelino Hernandez thanks for watching

[@rickeykeeton71]

I made a popper as you call it for checking refrigerator compressors. I think I will make on for checking the transformer with a fuse in it.

[@markkoppisch705]

Nice!!! I have seen mice go for the line voltage wires outside. What a mess!!!!

[@letslockit]

Hey Steve I've seen in your other videos that you have a tool you call a popper. You have a 3amp fuse in it and it pops instead of burning up fuses. Can you tell me where to get one? Thanks and great video!

[@truckinforever985]

Now is that inline fuse you installed an automotive inline fuse like you can buy on Amazon

[@josephgrassa3085]

Good thing I used a fuse!!! Good job Steve

[@deltafour1212]

What is the name of that style of fuse holder? Did you get it from a automotive store?

[@stevenlavimoniere]

yes any one will work

[@philjones5312]

Good tips Steven I am impressed

[@stevenlavimoniere]

+Phil Jones thanks for the comment

[@LmTeamWaxOffroad]

Very good video!! great from start to finish!

[@stevenlavimoniere]

thanks clemons

[@ArcticairLLC]

That blower motor sounded like its on its way out, or maybe a weak cap.

[@stevenlavimoniere]

+okpues77 cap was good

[@petesingh292]

Can you plz explain why you are wearing gloves ? Does it protect you from getting electrical shock? Plz do reply, thanks

[@MR-nl8xr]

@pete. It's regular practice in the industry, never know when you have to pee. A little, but not really.

[@vincentpadalino8003]

Love those attics....lol Momma be proud of that one

[@SteveSam66]

Nice Job, great troubleshooting.

[@stevenlavimoniere]

S Sam thanks sam

[@petesingh292]

Hi Steve , your videos very informative . I burned 2 transformers always on primary side when the shorts were found on low voltage at the condenser. Can you plz explain

[@rickeykeeton71]

Pete Singh From my research, the contractor is the cause of a bad transformer about 80 percent of the time.

[@Madness187inc]

I get a lot of 2 wire issues where I live due to rodents, there are times I was blown away by a contactor taking out fuses, ohmed out just like a new contactor, no issue with the 2 wire yet it kept blowing fuses, changed the contactor and fixed. Had this happen to me twice, any tips?

[@rickeykeeton71]

Daniel Cortez I think sometimes the contacts on the contractor go bad, stick or start arcing maybe.

[@Bluecollarworkingman]

Man, im a go out to the van and ohm a brand new contactor and then ohm a bad one now. That was dope.

[@158mollie]

Same thing on mine but the blower goes on but no low 24 volts to contactor outside but if I push down on the contactor the ac unit runs. the transmitter is buzzing and its hot. RHeed unit

[@raczyk]

do you test the 120v-AC and 24v-AC with the power on to the furnace?

[@anthonygasparini1734]

Flippin mice that's the problem!!! Nice video Steve!

[@lexischumacher1]

yeah been there done that as well, Hadda lady scream!!!! when she saw the mouse, lol what is it with women and mice?

[@stevenlavimoniere]

Gary Schumacher mice are a problem for sure ,can get nasty

[@heavydiesel]

Nice detective work Steven!

[@stevenlavimoniere]

thanks heavy diesel

[@Eddy63]

Steve , this is a very good troubleshooting video , very informative and great teaching tool

[@truckinforever985]

What size gauge wire is your inline fuse that you are installing on the transformer

[@willie1950]

Excellent troubleshooting. Ur a Pro.

[@stevenlavimoniere]

willie1950 thanks for commenting

[@lalibabee5114]

My air conditioner will not turn on at all. No sound no fan no nothing. I think it may be the voltage but I'm not sure. It was working an hour prior. Then it just stopped. It's been off for a week now, nothing is turning on

[@myronsmith2114]

What the hell are those red wire nuts on the outside of the air handler

[@chilo31416]

Does 27V reading on the 24V output side of a transformer sound reasonable?

[@rikstarmrz7]

Yes all transformers I've installed read about 27v

[@PlausableApple4]

Interesting scenario you had there Steve. Stuff like that interests me. It makes you think.

[@stevenlavimoniere]

i like troubleshooting

[@PlausableApple4]

It sounds like fun. It could be anything when it comes to electronics.

[@myronsmith2114]

Smart call on that fuse block

[@jonbri4383]

At 16:32. Make sure your Snapple does not have aspartame in it it’s not good for the body it’s an artificial sweetener.

[@VeryPersian]

At 10:00 you mention positive and common. I thought it didn't matter how you hooked up the 24v wire of the contactor? They are often not marked on new transformers.

[@stevenlavimoniere]

yes it does matter if you have 2 transformers hocked up to same line .if it sparks when touching =switch wires or you will fry them .

[@actechformallyyomama746]

Had a call that this lady had birds in her duct work. I just grabbed my small bag. Meter and a couple but drivers. She has 4 5 ton gas packs on the roof and a 2 ton split wine cooler. When I went to the 2nd floor in the bathroom and the bedroom you could hear birds chirping. I get up on the roof and go to remove the duct cover when the momma raccoon comes out from under the cover. She’s pissed growling hunching down. She wants me gone right now. I’m not feeling very welcome at this time. All I have is my little bag. Do I throw the whole bag or things one at a time? The raccoon takes off running and I head for the roof hatch. I get downstairs and the lady asks me if it’s bad. I say it’s much worse than we thought. You need animal control. Did you known how similar baby raccoons sound like baby birds. Lol true story.

[@hvac526]

It wasn't low ohms. Direct short. Correct me if im wrong never heard low ohms tripping fuses or burning transformers

[@stevenlavimoniere]

KQP Twin low ohm= a short just so you know

[@hvac526]

Ok ill take your word for it. But original cause insulation off the copper wire touched metal direct short. I trust your experience.

[@Josh-px6xb]

Do you charge them for all the parts added?

[@JasonSmith-qx3zh]

That heat will make you say things about those rodents lol ! Great vid you r da man.

[@truckinforever985]

what gauge wire on the inline fuses , and are they automotive inline fuses

[@louperez953]

Sir, thanks for sharing your knowledge

[@rocker8692]

Steve you're next level

[@kenlafountain269]

do you have a helper on this job. I think I seen a guy with gloves

[@stevenlavimoniere]

i work alone .dog is in training

[@bushcraftchip]

So the loss of resistance causes in rush of current then POP???

[@jrmcferren]

He had a short, it is simply cheaper to replace a fuse than a transformer.

[@davetervo4058]

found that a couple dryer sheets keeps the rodents out, try it

[@stevenlavimoniere]

Dave Tervo i will have to try that out

[@Ronaldoo91]

would blower motor continue to run even without a working transformer?

[@kwamidessouassi7988]

No it wouldn't work

[@eastersheatingandaircondit4983]

I had a dang lady bug get on the coil of the contractor the other day and shorted the transformer! A lady bug!!!!

[@stevenlavimoniere]

nothing suprices me anymore

[@ESDI80]

I didn't realize those little transformers could put out 5 amps. :-) How much do those run price wise? Could be handy for my electronics projects! Nice fix!

[@stevenlavimoniere]

there only like 20$ or so .i have all kinds in the truck
