H3 is for a high temp compressor sensor. Since you’ve ruled out it being caused by a dirty coil or faulty TXV, consider testing the thermistor sensor located on the compressor. Expect you will find the thermistor out of range or poor wiring connection.
I'm about to graduate with my Associate in HVAC/R and these Mini-Splits seem to still be something of a mystery. We have worked on them in class but not a lot of good repair info to be found on them and finding parts can be really hit or miss. Especially if it is specific to a particular brand. I did purchase a book that deals with generalized mini-split service procedures, and it seems to be pretty detailed with a lot of information. I haven't had time to really dive into the book yet but that is my plan as soon as I graduate so I can focus more and learn all I can about them. It will probably be necessary with these becoming more popular. Seems like people either love or hate mini-splits, not much in between. I have a few of my own and they work well for me.
If I run across a mini split systems the first thing I check for are three little letters PRC. That means the system is a Chinese manufacture, not just made in China like most of the major mini split systems are made but a Chinese company. Don't stop keep running away. PRC means People Republic of China, and good luck if you're trying to get in contact with technical or find a manual. As far as I'm concerned they are throw away systems.
I’m thinking it’s sensing a high compressor temp too. Possibly the thermistor has drifted in value but without knowing temp vs resistance it’s kinda hard to know what’s what. Hope your hand is doing better. Have a good weekend and give Riley an extra treat or two😊
What is the tool bag you are using now? Are you finding it easier to work out of? A month ago you were using one with Velcro at the top, it looks like you switched back pretty quick to your normal bag. Pros and cons please. Is it time to do an updated tool bag and tool video? You always have the right tool for the job. Time is money, wasted time is lost money!! Thank you for all the information you provide in your videos.
Inverter type air conditioner In the external piece, there are 3 sensors connected to the inverter card that are responsible for the work of the compressor,,, To measure the ampere drag of the compressor, you must open the front piece and measure the withdrawal of current from the wires between the inverter card and the DC compressor
I’ve been noticing my field piece app won’t load when I have really bad service. Ticks me off, I shouldn’t need good service for the app to work. I have one whole development where it never loads now.
@@allanbrito13 One would assume you don't need to "log in" simply to read data from the probes you've already bought and paid for. Otherwise, where's the sense in dropping $700+ into the hardware only to find you can't use them in areas of poor service? Especially with that recent AT&T outage a few weeks ago, where a massive quantity of phones didn't work due to a coding error; a tech loses far more money than the $5 credit AT&T offered as compensation (and only to its contract customers, but that's another discussion for another time) because they had no internet access.
@@davidb2438fair play to you. You're the only one worth listening to here including the one who made the video. He's as clueless as most of the responses!😮
my SOP for mini splits is to recover the charge and find out if it is correct . I replaced a circuit board per tech support once and still had the same issue then I recovered the refrigerant and the system was running on half a charge so the company I work for made it a rule to weigh out and weigh back in the proper charge , the compressor overheated for some reason . I noticed the liquid line frosting up in the cooling mode ? or was I seeing things ?
Exactly that. Spot on. It's almost certainly a charge issue. Might even be mixed refrigerant. Worrying that some are blaming the fan motor sensor PCB etc when the obvious right there in front of them...
Yeah reset was a good idea you should tell the owner if it keeps happening it's probably one of the boards is going cuz that's usually when you can't find anything on a weird error code it's usually a bad board somewhere
@@anthonydesisto2328 Late response.... Nope, when he used his phone to take a picture of the fuses in the disconnect earlier in the video there were two pieces of half inch copper pipe in the fuse holders. Later in the video it shows him putting in correct fuses and a few moments later you can see the copper pipe pieces on the porch to his right with some of his tools. Glad that potential fire hazard was fixed.

Thanks
I just had to do the same for my Mitsubishi MrSlim... I replaced the entire Thermistor set and it works perfectly.
Check the wiring at the compressor. I have seen a few crusty connections and then threw a compressor error.

That’s pretty much a gree system and h3 has to do with the compress overload, maybe the condenser fan isn’t running or a dirty cond coil.

It’s possible the fan not spinning fast enough? Maybe bad fan motor
Do you do consulting??

This is the OT-LC and I like having everything right where I can reach it. I have a couple of others, but this one and the Tech-MCT are my favorites.

H3 sounds like it has something to do with high limit cut off h3 you know that's the first thing I would think of so it overheated for some odd reason
Thank you
Never heard of that Brand or Model Number before. 🤔
It looks identical to GREE. I’m sure it’s a rebrand
That noise from the compressor it is like knife into my heart
High pressure switch faulty

You need Internet to log in

Well Curtis, with the Power Off/ Reset may have cured the fault ? 🤔 Au
How 'bout them "NO BLOW FUSES" at 7:54?
i know i saw that too ! Classic homeowner too Lazy to go to hardware store spend $15.00 & Would rather burn down the house scenario. 🤦♂️
At 12:00 minutes I noticed line to evaporator is frosting. Maybe leak, low charge, high superheat causing compressor thermal shutdown.
On mini-splits this can be normal. The expansion device is in the condenser.
I know EEV is in condenser, but a line after EEV below 32f is still an issue that should be investigated

whats that filter look like in the inisde head unit?

H3 Condenser Fan isn't spinning as fast as needed and or Condenser Fan Motor is bad.
My rocking that 11 in one. Hell yeah. 3:33

Copper pipe fuses? Hope there was a correctly sized breaker upstream.
Those were regular fuses.

I found Wobbon code chart
Yeah looks like I was right compressor high limit I said it was going to be something with to do with high limit
Probably an overload protector for the comp.
HEY CURTIS TAKE LOOK AT LOW SUPTION IT IS FROZEN LACK OF REFRIGERANT AND HIGH SUPER HEAT IT MEANS HIGH TEMP. AT THE COMPRESSOR
👍👍😊😊
And I'm just guessing here by the way everybody
Discharge line Icing up Curtis you missed it we not perfect we a human after all 👌
In minisplits this can be normal. The eev is outside.
low charge issue, high super heat and a frosting discharge line, its likely freezing up and causing the compressor to overheat
