The dude at the factory was having a bad day and the QC dude was at lunch....lol
I got tired of waiting while you were thinking, so I zoomed ahead. Unless I missed something, was there an error in the factory wiring of the AMP/Molex connectors? If you have to pull the pins once in a while you can buy a tool for extracting the pins without ruining them. Both AMP and Molex sell the tools. Most people get bored watching stuff, so you might want to go through parts where you are "thinking" and speed things up in those areas. I don't shoot youtube videos (although I have) but I know that people get bored, so it's just a suggestion.
BTW, I got called on a 20 ton unit that was inop. I found that whoever worked on it before clipped a bunch of zip ties. The 240VAC line eventually rubbed against the frame of the unit, wore through the insulation and shorted against the frame. It caused a huge ground fault current that it stated a fire. Eventually it put 240 VAC on the 24VAC control lines and blew all coils that were connected to 24 VAC. All because somebody left some zip ties off. Most three phase lines are not 240, from my experience it would be 208, but this system was 240 phase to phase, I thought that was unusual.
By the time the relays were all replaced and one klixon, the system was back to work again, AFTER making sure that no wires were free to touch things.
Thanks for the video, look forward to your next one. Jim
Curtis strikes again! Way to go Curtis
I have seen high voltage on the low voltage before. A customer let his neighbor wire in a new transformer and he wired it up incorrectly. Luckily, the high voltage short blew the fuse so his low voltage circuitry was not destroyed. Most people who don’t understand electricity usually don’t mess with electricity. There is a small percentage of people who will mess with the wiring because they are too cheap to pay a tech and they are lucky if they don’t kill themselves.
@@Bryan-Hensleylmao I hate when the customers try to wire their own stuff. Also scary.
Years ago I installed a new unit somewhere I don’t recall what kind it was. And they had done something like you found on this one. I had 240 V I believe going to my defrost thermostat lol because it blew the thing apart. I don’t remember how they did that but they did it, it was a brand new unit. Not very often but once in a blue moon, I’ll come across something like that.
Quality control at its finest....
I agree.
Now you have a great excuse to buy another tool for you arsenal. Terminal depinning tool would work great in that instance. Thanks for the videos.
DEFINITELY!! Im a mechanic and watching him try to yank the pins out made me cringe....
My depinning tool is called wire nuts, lol.
I keep a sharpie in my pocket for making witness marks on those connectors and others like them. Just a little trick my dad taught me.
28 years in field and retired don't miss on call on holiday surprised it didn't burn out the fixed anticipator on Stat there not supose to handle 120v keep hydrated its hot out there plug must have been missed wired at factory it happens
They sell a small tool that is used to remove the pins from a Molex connector without damage. Insert from the front and just push. No breaking the wire off.
and that tool is the tiny minus screwdriver that we use for the thermostat wiring. just insert it all the way where the Pin is holding the plastic body of the connector, at the same time pull the cable. it has worked for me quite a lot of times. You can carefully observe the mecha when one of the pins you pull out. otherwise, use force like he did.
Both Amp and moles make the tool, each brand has two sizes, for the work we do, the larger size is best. We used to have electronic supply stores, most are gone now, but I'm sure you can but the exreactors on the internet. In a pinch, a small jewlers screwdriver will work too. Jim
Meant Amp and molex.
.
They make a tool for that but tstat screwdriver is what I use slide it down and push the tiny metal tabs back it and it slides rite out or wire nuts just as good I installed a brand new Lenox system few years ago and from the factory they had the plug pinned wrong they were sending power to w2 burned u bm p tstat sequencers transformer it was aggravating ready to start ot up all cleaned up ready to go home for the weekend lol
Thinking the installers asked the lawn guys to wire the unit?
Strong Possibility. 🤪👎
Nice job and troubleshooting Curtis.
I usually carry a cheap tstat to bypass the indoor tstat when I cant get in or have to make multiple trips in and out because the resident keeps turning it on or off. Also it lets me check both heat and cool functions to prevent a call back when season changes. Great video!
That’s what jumpers are for
I have one with teach that wire already hooked I just put the small blue wire nuts on there and hook everything up my pasty inside house one saves you a lot of trips and callbacks
A well done job Curtis 👍 Au
Love your work ethic and dedication to all those who do what they do to help residents be it owners or renters! Thank you sir!
I appreciate that!
Good catch!! I'm glad you found it with the tester and not your fingers!
3:58 oh he found it with his fingers all right
Great job Sir. 😊
Thanks 🙂
Excellent analysis. Tough one, no doubt.
Much appreciated!
I had that happen inside an electric furnace. Some uninsulated spade connectors were touching and there was 120v on the tstat wiring. It bit me and made me jump.
Wiring that is not needed, and one carrying 120 volts, IDK, you got me on this one. Where was the voltage coming from? Anyhow, you did a nice job. That is the difference between a pro and me, I would have done away with that connector and broke out the wire nuts. Kudos to you, I use to work on labor day too. It was better than getting behind.
West Alabama here to
What was needed inside the house? Couldn't you just jump the thermostat terminals on the outside unit? Unless I missed something, it seems the only thing inside would be a thermostat, which simply switches the unit on. The entire machine is on the outside.
Seen it where the home owner had a handyman "Fix" his package unit. Grabbed the heater control lead and pinched it onto the probe with my thumb and forfinger like I've done 100's of times before and Zap!
Shoutout to all the service techs that had an emergency call at a 24 hour facility today. Y’all make the world go round.
It makes their world go round too with the extra rate they charge. $$
@@jthonnAmen
You have the patience of Job and a fantastic ability to focus. As Todd of Project Farm would say, Very Impressive!
Thank you very much!
took a little extra time but got it fix. be bless and safe on labor day.
Wow! That was terrific!!
I can’t find a copy of the heater package to package unit wiring but do you think it could have the power wires you removed went to power the blower during the call for electric heat. Was just thinking about it what do you think? I know you fix the miss wiring but maybe the wrong hardness plug was used from factory
I ran ino this same problem with a couple carriers air handlers so keep an eye on those 22-23 models are the ones that the plug needs to be rearranged just a fyi
Good Job Curtis. That is unusual to see a messed up connector from the factory. I guess it happens with all sort of equipment, once in a great while. Maybe it was the day after too much tequila! Glad you didn't get a bad shock. Yes, they are happy now. Those mobile homes can get really hot, really fast.
Nice job figuring that out!
Those molex connectors are fairly easy to get the wires to release simply by using your tiniest screwdriver tip to reach in from the front of each half of the connector to gently push the release barb/tab towards the wire. Then you can push it back into it's correct slot w/o damaging the ends.
Agreed! It hurt watching him RIP the pins out of the Molex 😮
They make a hollow tipped tool to remove pins, stops all the hackery he caused…
@HVAC GUY been watching your channel for a while now. Curious why it seems like almost every system you work on there in GA is a combo pack. What is the reason behind that? Is there some special reason almost every house has one, not only that, it seems like Rheem/Ruud have the market NAILED on those installs as well. I'm in Texas and we have similar houses to those in GA (pier and beam, not many basements), and you hardly ever see a package unit here. Thanks for the content!
Also, apologize if this has been asked before, I've never seen you talk about it.
Thanks for Making the Trades Great Again. Mikey Pipes always says, if you’re Not Testing, you’re Guessing. You LIVE by those Simple Rules and it’s Obvious. 👍🙏
I appreciate that!
Could Goodman have created this abortion in their factory❓
it seams every time or most every time there is a bade wire you stick your hand on it.. love the videos
What a weird one!
Man they really do go all out for Fall decoration wise, even did the inside of the unit..............
good job
What a jewel! Almost electrocuting somebody. I don't see any sense in having two disconnects🤔
I couldn't live without my Molex pin extractor!
That was a great troubleshooting Video, Thanks😃
IKR, 2 disconnects is crazy.
Looks like one disconnect is for the compressor/fan and the other is for the add-on heat strip kit.
@@brianleeper5737 Yes I saw that and it's probably not a bad idea but most installers are too frugal
Curtis I think you should charge them extra to clean up the area surrounding that packaged unit! 20 feet in three directions!
Ur a super hero 👏
Golly gee Batman
Good job troubleshooting
Ouch! Curtis, you need the Molex® pin extraction and insertion tools.
Yes, I do
Send him one Ray!
wow, that's crazy. I would have spent a good 45 minutes tracing all the wires with the schematic XD
Your analytics are first rate and the results speak for themselves. I think you may be following that technician for a while. Thanks for your efforts in letting us spend time on the job with you. You are what Labor Day is about!
I think at 10:43 I saw another, similar but empty plug in the bottom right corner of the lower electrical box
Great job once again. Hope your labor day was not a total loss.
Tank you . Sweet tech troubleshooting. 🤟
that was certainly a wtf moment! hard to believe that it was wired that wrongly.
Does the schematic diagram show the proper configuration of the plug?
Never looked at it.
He's got a wrong electric heat kit for this machine. That why he's got to pulled wires from molex plug. A simple repair is he needs to get a correct heat kit for this Heat Pump package He doesn't need to pulled the wires from molex plugs. Those just a temporary fix for ac ONLY if he does not put back some of the wires he pulled it out this heat pump won't do sh!t in the winter.
@@usahoangsatruongsa He's in georgia so the heat kit is basically useless anyway. The heat pump will be fine on its own, guarantee they'll almost never see a day cold enough to require emergency heat. Lowest temp they'll see is probably in the 20s maybe for a few days in january.
Yes always on all units and all brands.
somebody is scared to use the brush LOL.
Damn, people blow your grass AWAY from your AC unit! And hose down your coils every 3 months! 👍
Every three months? I thought I did mine too much. That panel had to be off when they cut the grass. Note, there were no screws in it.
looks like a fairly new unit
I think it was a new install that never worked.
Isn't that a MOLEX CONNECTOR. How did you remove the pins without using an extraction tool?
I have one of those extractors I bought from Radio Shack about 25 years ago. Used it a few times a year on average.
He is really strong. I saw him snap a screwdriver shaft on one of his videos. I never thought a human could do that.
Not only physically strong, but mental ability off the charts👍.
Hi bro from west Alabama
I am glad that you did not get bit by that "low voltage". And I would not have been surprised is the thermostat, contactor or some other low voltage parts were burned up.
That would have been a big bite.
I thought he did.... 3:59
@@NJPoolboyyup he did
Pretty sure he did. I heard him grunt when he touched the yellow.
What’s the model number on the side of that Milwaukee blower?
When turn it on its sweet music!
have to depin the connector it has a release tab that has to be pushed down to release the wire a needle very small screwdriver or something like it will work or they make a connector depin key for cheap also Great Vid as always Great Job getiing it up and running
What then, was the purpose of the wires you removed? Was this just a botched install? Had it been working?
It had never worked before
@@HVACGUY Ah. Well, it does now. Too bad you're not in the Knoxville area...
Hey Curtis I see the Hartland controls relay breaker on the unit just curios if that is a culprit again. Maybe it's not doing it's job going to the molex connecter.
Great vid.
Please get your self a bunch of plug de-pinning tools, they look like a keyring of different size straws, it makes taking the wires out of the plugs really easy and makes you look better, better than ripping wires out with pliers, cave man style.
Once I found a proprietary factory Carrier charging device laying in the bottom of a condenser. I brought it to the supply house and ended up with a store credit from carrier.
I once found a unit that was putting out 120 on the flame sense terminal on package unit outside. It worked just fine tho. Would shock the shit outta you when you try to pull flame sense off thi 😂
You have a bad thing-a-ma-gig. A gallon of gas and a match will fix it. LOL
They make a molex pin removal tool. I keep one in a bag but I've never had to use it in hvac only custom wiring a pc.
Great Video. Thank you for sharing. I'm new to hvac. Is that Unit come from factory wires wrong , Is that wires wrong blower motor ?
Can't that line voltage didn't let the smoke out of the t-stat. 😡
Should be "can't believe that line voltage didn't let the smoke out of the t-stat"
very interesting!
Did I miss it? What was the cause of the high voltage? I know he repinned the connector, but where was the voltage getting into the low voltage??? I do commercial and never touch residential so I’m behind the curve. Seems like the two shouldn’t be in the same plug or wire path.
IMO both those electrical whips are not code - they don't loop down before going up.
You are probably right, I didn't think you had to have a drip loop using conduit. I still don't get why there were two.
Somebody ordered the wrong heater
Exactly. There are 2 different models for these goodmans. Someone probably installed the Kit for an AH in a Package unit
Why does that AC unit have 2 breakers
One for the electric heater and the other is for the rest of the unit.
That purple wire goes to the fan in defrost mode to keep cold air from blowing on the client
You did a great job but how did work before. Or was it’ on startup Also lucky it didn’t burn up the thermostat and other 24 volts stuff
It has never run before
@@HVACGUY Thanks for getting back to me. Enjoy the rest of the holiday
Those wires won't stay in that connector since you didn't use a removal tool and the locking tab was probably broken when you used pliers to pull the pins out.
The connector uses a pin removal tool made by Molex. It is basically just a small hollow cylinder that pulls in the barbs attached to each pin. It can be used on both male and female pins.
Used them all the time as a Xerox tech rep.
@@johnblystone8781
You are right I'm sure, but a little luck can save you sometimes. Wire nuts would have been the answer for me.@@johnblystone8781
How did 120 volts not fry the tstat? I ask that because I've done it before with an old bi-metal fan timer.
Check out the stair railing in the background. WTH!! Maybe it's just my old eyes.
Your Eyes are Good but the Eyes of the Dude who Built the Railings is Definitely Suspect. 🤪👎
I had a package 3ton Goodman hp. Same issue
Amazing!
Probably would of been better to get rid of the big molex connectors and use wire nuts or wago connectors.
Not being a Ahole but still should check to make sure power is off , I’ve seen disconnects straight wired before. The goal go home everyday.
That install looks like a rookie beginner installed it,
How in the heck did it pass Inspection with the low voltage penetrating the unit without the wires being in seal tight with an internal wound Metallic whip? and a chase nipple installed for the low voltage wire penetration into and through into the unit?
Most city or county inspectors would shoot it down upon inspection and not pass it with a fix and change write up list.
Also I'm wondering why a low voltage wire if it's a package unit? What's the low voltage wire for?
Also why is there 2 disconnects with only ONE unit?
Nice job
Youre always humming a tune from last song you heard getting out your service truck. You should tell us what songs they are
i love your work! quick question, why were you able to cut the wires from the contactor going to the pin connector ? were those wires not needed ?
I cut wires from breaker to molex. No, they weren’t needed or used.
@@HVACGUY I meant to type breaker. But thanks for all your wisdom. I’ve been in the hvac field for 2 years and I’m still learning everyday. Im also trying to get all the vocabulary memorized 😂 thanks for all your help!
@@HVACwithIce In another 20 years you'll be an expert! LOL
I hear ya Bob, there are many experts in the boneyard.@@bobboscarato1313
Throw a small jewelers screwdriver in your bag...you can release the pins in a Molex connector easily by depressing the tab on the pins.
That came from the factory wired wrong.
Boy they are really pumping out quality products aren't they
Very tricky… low and high voltage are always separate
Did you look at the wiring diagram? Did you bust the UL rating by cutting away the wires? Is that the proper heater for that unit? Lots of considerations on this call. Nice bud. That low voltage surprise never gets old. Got bit a few times myself.
I was thinking the same is that heater kit compatible with that unit
Hi Curtis I believe your case is you've got a wrong heat kit for this Goodman package. Some guys who installed this bought a wrong electric heat kit for this machine. You fixed it and I believe it's just a temporary fix you need to come back to get them a new heat kit otherwise they won't have heat during winter time. Take care !
Right, since its a heatpump, they might call you back when its winter! Looks like the unit was installed in the winter time by some croo*s.
You have got some Nice tools to work on stuff with, but I can Barely hear You on Your Videos. I don't have any trouble hearing Steve Lav or any other Videos.
Sorry about that
It kills me to see you pull those wires out like that out of the connector!! That’s why I keep a pin pull in my truck & extra connectors in case.
so was it miss wired from the factory?
Don't ya just to start the job off with a ugh oh damn that's hot sob made me chuckle only because it's happened to me
The Hay Bailers that Left the Cover Off the Outdoor HVAC Equipment need to Find some Other Occupation since they have already Proven they are Clueless. 🤪👎
Maybe it was the tenant or home owner trying to "fix it". Got frustrated and left it that way!
you need to get some depinning tools, for those d sub connectors, or a small paper clip or a micro flat blade screw driver will push in those tabs for the pins and they will slide out, without having to go 800lb gorilla on it, haha
Yes. I do see a need for them.
Your supply house should have molex pin extractors for about $10 ea, they cit down on the frustration of doing work like this
