Retired after 35 yrs in our trade. I skipped the residential side and went straight to commercial. I'd rather work on a 75 ton chiller then deal with what you just worked on. I think the old saying is true..the smaller they are the harder they are to work on. You have a patience of a saint . I probably would have tossed that board across the yard. Nice work love your videos.

Good guidance. As a senior tech youre right nornal customer thats wants simplicity and not astronomical potential part changeouts dont need eauipment like this . Load changes everything especiall poorly insulated structures

For as long as inverters been around they still can't get it right. They used inverters in the 1960s for the NASA Mercury and Gemini space programs and it's still junk. It's going to get to the point when you have a problem with the inverters, technical are to tell you to get a new condenser . Most of the time technical does not have the answer. I would never sell a customer an inverter system I would not go any higher than a 2 stage heating and cooling system. Good video sorry it had to be an inverter.

I remember when i first started residential HVAC, i had a call for no heat wih a rheem furnace. LED was blinking 7 times but the list only covered up to 6 blinks. After an hour with tech support it turned out 7 blinks meant weak flame signal. That was before they started putting the orange "flame" LED on the board.

Luxaire & York what a lineup, surely not first string.

I have a carrier infinity communicating unit with this same inverter board. What a piece of junk, expensive too!!!

Man that coil is packed.

Great video Charles on those inverter boards it's often just the capiciters just like on a lot of the units you normally work on the diference is the capiciters are soldered on the board. Which is why you have they tell you just replace the board I can tell you those capiciters look like big versions of capaciters used on computer motherboards and electronic equipment and mini splits and gree and Samsung and Mitsubishi all use those same type of boards for the condensers and inverter systems. So you may want to find out the exact capaciters used in them and grab a, soldering iron and capaciter testers and just solder up new capaciters I know some hvac guys who work on inverter systems have actaully done that at least for the Samsung stuff. or find out what that exact board is on those units and other inverter units and then do a Google search and by those boards in bulk to keep stocked on your truck like the old scholl capaciters or at least keep those motherboard style capaciters on your truck so you can unsolder and replace those capaciters as an option if the custumer is in a pinch and Charles that system looks at least 5 years old maybe 7 to 10 years old and we all know capaciters these days often go bad in 5 to 10 years. Great video keep em coming.

Every day is a school day Mama.

Ohh Charles sorry to comment again but lux aire is a Johnson controls product just like York now is and like I said the pre Johnson controls York was a much better company who made good hvac equipment for the residential and Comercial sector I mean there are in my area old Yorks on Comercial buildings still kicking away that are 25 30 years old. I mean Goodman is not even Goodman anymore it's owned by diaken. But those darn design flaws these people who are designing those boards obviously did not think out real world conditions like Samsung does or other companies even gree as my inverter board does not have a heatsink like that facing where all that hot air hits the heat sink that's not acceptable to me at all should be smaller and face the same direction as everything else on the board. Just my thoughts Charles but you got it done.

Ohh Gabriel comment anytime you like, I am well aware that Johnson Controls is behind this disaster of design, and by the way LUXAIRE is one word. The sticker on this unit says Johnson Controls and York but that has nothing to do with the fact that it is a waste of money. And the heat sink is a struggle, Trane was able to use the refrigerant line as a heat sink, which makes since but the airflow across this one works OK.

@@myHVAClife ​@myHVAClife it's just ridiculous is my point I have seen inverter boards from Samsung and other companies like Mitsubishi that don't have issues like this. I also think when they design this stuff maybe they out to think about how it will actaully function in real world conditions and effect the technicians working on it years ago car guys had to become computer guys but now it seems like it's happening to hvac it can be done. But it should not be a Comomicated mess I know with those capacitor types vs what you guys are used to is what you find on stuff like computers tvs. Radios and requiring soldering irons. But can you expect a custumer to wait. 3 days to a week while you take the board to a mom and pop computer repair place if one exists let them test and do the soldering for you to avoid liability. And that's my point but Charles even 1300 dollars for that board is pushing its more like 500 to 700 dollar board maybe less. And that board size is too big it's like my full size atx motherboard most I have seen of these inverter boards are a lot smaller.. So I feel for you Charles maybe it's because I am from Pennsylvania and an hour and half away from the original York plant which was in York PA. And I hate seeing all these once great American companies get bought out by foriegn companies like York goodman which diaken owns and enough Charles with the vrf stuff and proprietary stuff. Come on you can do inverter technology without proprietary communicating exclusive stuff gree has done it. Mitsubishi has done it pioneer has done it it's about darn time the American companies start thinking about side discharge designs like mitsubishi gree pioneer and most other countries. But do it better amd don't get me started on the refrigerant debacle and yes I am all for enviromenrally freindly refrigerant but before you start pulling stuff find a good replacement and stick with it. Heck blueon has one now and in my view that should be the standard maybe with one other but now it's the same crap with 410a ohh know let's just force r 454a ohh wait 544b ohh wait you lose efficiency and capicity. When ohh there is a fix for that just make r 458a the standard and have the technician replace the pressure switches with r 22 type lower pressure switches heck you could probably use mo 99 too as another option and ohh wait they make adjustable txvs too ding ding just have the technician install those too and guess what those evap coils and condenser coils will stop having so many leaks developing with the reduced pressures more like r 22 and more efficiency which is better on the compressor. And ohh wait much colder air VS 410a at least with r 458a. My point is I am sure you guys would rather put pressure switches in and adjustable txvs in and seal replacements as necasary although rare VS. This ridiculios nonsense of selling someone a brand new 410a system only for it 2 years from now 5 years from now spring a leak and ohh wait you can't get 410a at reasonable prices and the custumer complains the 410a refrigerant just does nor work quite like the Old stuff. Hope my point is made and I do feel for you guys.

i have a york from 1998 still kicking . and my brother has a Tempstar from 1993 over 30 years old (back when intercity owned them) before ICP. still working. aside from capacitors and contactors change outs in both everything is original

Does any purchaser of these inverters ever get their moneys worth, expensive, immediate parts availability?, tech knowledge, are they going to live long enough to pay it off and god help you when and if it surpasses warranty phase, absurd parts amount/availability.

Somebody doesn't do they're maintenace

my nephew had an inverter and four companys came out and they could not repair it, he replaced it with a regular ac

Because they did not know how to deal with inverter board systems it was probably the capaciters but if you watch the video they are soldered on the board VS what most hvac guys are used too. So that's why most tech support guys say just replace the board. Because other wize you have to desolder the capaciters resolder them and if the hvac tech does not do it corectly you can damage the board in other words it's a liability issue if you don't do it right that's why they say replace the whole board maybe it's time in hvac school they teach hvac guys more how to work on these boards like you would learn in a computer repair class or electronics class.

Sounds like sheer incompetence to me. It could’ve very well been repaired.

Inverters are not worth it! Boards are 1500 bucks. To expensive.

I disagree a good soldering computer repair electronics class for hvac guys would help as it's probably the capaciters just like on a conventional hvac system it just uses an electronics type soldered capaciter VS what you hvac guys are used too. And a fully assembled computer mother board costs that much if you diy your own desktop computer like I did. Including graphics card thermal paste cpu ram or memory modules but the motherboards themselves are like 250 to 300 dollars. But if built well will hold up. And I am just saying because I know the cost of building your own computer but that board itself in parts was probably 250 dollars.

​@smacleod69 ahh but eventually all units come out of warranty and I know In Samsungs case they actaully send to the hvac technician replacement heatsinks and capacitor packs and instruct the technician on how to install it. But I do agree board replacement is often the safest but 1300 dollars is excessive for one of those boards I can tell you to make one of those boards does not cost even 300 dollars to make. So the part should cost maybe 500 dollars maybe 700 at most.

Anything JCI is garbage
