High Voltage On My Low Voltage!!

[@steveoh9838]

The dude at the factory was having a bad day and the QC dude was at lunch....lol

[@picklerix6162]

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.

[@mitchell8204]

​@@Bryan-Hensleylmao I hate when the customers try to wire their own stuff. Also scary.

[@josuerubio8002]

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😃

[@jthonn]

IKR, 2 disconnects is crazy.

[@brianleeper5737]

Looks like one disconnect is for the compressor/fan and the other is for the add-on heat strip kit.

[@hinspect]

@@brianleeper5737 Yes I saw that and it's probably not a bad idea but most installers are too frugal

[@Fraid-Knot]

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.

[@natersalad889]

DEFINITELY!! Im a mechanic and watching him try to yank the pins out made me cringe....

[@jthonn]

My depinning tool is called wire nuts, lol.

[@RobertTuck-vo8cw]

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.

[@jimwhite9483]

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.

[@bwoutrage21]

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.

[@soundgineering4771]

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.

[@emptech]

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

[@emptech]

Meant Amp and molex.
.

[@emptech]

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

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.

[@jimfeagins9424]

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.

[@G_Machine_Joe]

[@usahoangsatruongsa]

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 !

[@soundgineering4771]

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.

[@stevelang3171]

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.

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.

[@johnblystone8781]

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.

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.

[@MegaDysart]

@@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.

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!

there are special tools for removing connector pins...all pins have tabs that hold them in connectors....the tools depress the tabs so they can be easily removed and reinserted and not destroyed

I know on the small radio connectors you just slid a pin in a hole right over the wire, some in the same hole on top of the wire and it would press down the tab where it would just slide out.
