Nice. Do some more on those infinity units if your so inclined sir. Also I’ve seen Some units even have power going to them when you hit/pull the disconnect switch too. They do some wack stuff out here. Always check if power is off.
I’m just now starting to get into mini split service/repair. I’ve got about 5 years experience with conventional residential systems and some walk in coolers. Do you have a course, book, or some other source that you recommend for ductless systems? “Seems” like the main thing for me to learn is gonna be troubleshooting the inverter / whatever other controls may be different than conventional systems. But there again, I don’t know these systems.... Thanks for your videos!
Great video, the company I work for has installed tons of those units in the last few year or so and I can’t tell you how many inventor boards and compressors I’ve had to change in them,first they had issues with the reversing valve solenoids being wrong from the factory also surge protection for the equipment is a good idea,it’s newer technology so it’s a learning curve for us in the industry but it’s definitely the wave of the future
Thanks That's odd. We are a Factory Authorized dealer and have installed over 1000 of these inverter units since 2012 and I've only seen 2 bad compressors and about 6 inverter drive failures. Ive never heard or seen a reversing valve issue with these systems. Only major issue if it can even be called that was a recall on a board in the 5 stage units and that recall effected less than 1% of all inverter systems ever sold by Carrier/Bryant. They have been incredibly reliable systems for us.
I work for a factory authorized dealer also we had a string of them where the reversing valve solenoids were wrong from the factory that caused damage to the inverter boards and subsequent damage to the compressors carrier has kits they stock for retrofitting the affected units with the proper solenoids we even got official documentation from them on the issue,I’m not saying they are bad units because I think the complete opposite,outside of the solenoid issue we experienced the only other problems I’ve encountered with them were from damage to them after thunderstorms most likely from power surges and the occasional problem from our installers over charging them and getting fault codes for high torque compressor starts which isn’t a issue caused by carrier or the equipment
Not a problem with the reversing valve itself but with the solenoid coils they also sent out a service bulletin for issues with the vna units catching fire from faulty boards in 2017 I think
I understand what you are saying. I'm just saying that in the 1000 plus inverter systems we've installed (5 stage and Greenspeeds) we have yet to have the issue you're talking about or the frequency of issues you are taking about.
@@HVACinSC Let me use this example, a AA battery is 1.5volts , next time your car battery dies, go get 8 AA's (8x1.5V=12V) Now try starting your car. See what happens.
It's potential and resistance. If you'd like to get technical... Its a combination of Volts, Amps, Frequency, and Time in the circuit that kill you. You cant have Current or "Amps" without Voltage. A more accurate statement would be that Amprage and Voltage kill you. 🤔

How the hell did you get 2 thumbs down? On great tech tip with visuals.
Haters gonna hate bruh! 😆
Because like Steve lav says mamas boys in a basement going to hate.
Democrats!
Looks like a VNA. Great video.
That's more than a tip its a life saver.
Good Vid. Thanks for making it !
Excellent !
Excellent tip, I like to check voltage every time I pull or shut off power! Stay safe folks!!
I need a good quickening!
Have never seen one yet, but knowing my dumbass, can see sticking my fingers in their thinking I'm safe since the disconnect is off.
Thanks!
This is JUST A LITTLE LOWER THAN A PRIUS, DRIVE MOTOR VOLTAGE, CHEERS FROM NJ
Very informative.

Great tech tip
Nicely shown
Where did you put your leads?
On the testing terminals
Great tip
Damn ty for sharing. Never paid attention to that
Those capacitors have big values and they need some time to discharge
That's what the video is showing. 👍

300VDC is more like instant dead... well unless you only get a hand banged, but you'll possibly loose some parts ;)
👍
Great tip man, keep vids comming
Thanks for the tip
Thank you.
Great advice.
Thank you for the tip is very appreciate it

Interesting. We have literally never had a single reversing valve issue to date.
Not a problem with the reversing valve itself but with the solenoid coils they also sent out a service bulletin for issues with the vna units catching fire from faulty boards in 2017 I think

Good tip.
Where are ur leads hooked up at on the board ? Never worked on an inverter.
On this specific model there are voltage output test terminals that I have my alligator clamp leads attached too.
thanks for the info.
Welcome to the world of variable speed drives. Water pump and air handler drives have this same problem.
Nothing new to me boss. I've been working with this sort of stuff for over a decade..
Just sharing information for the new guys. 🤙
Good to know
Jeez, It's not the Volts that'll light you up, it's the Amps!
I hope you know that's a myth
It's neither of those, its the amount of energy that has flown through your body.

Make more helpful videos on inverters!
👍
