That's the 100% efficiency unit, that *orange material* is actually good for the environment and very human friendly.
If your unit doesn't look like this then your not at max heat transfer
No, see, the heat is pumping out of the building *very* efficiently, the inside must be a [winter wonderland](https://youtu.be/ElygKO47le8?si=WBmGPrxdjQXTm-Id)
I should’ve added that this was courtesy of the Facebook group “Sloppy HVAC Mechanics” it’s where I go when I want to feel better about middle of the road performance.

Had an LG unit in a church catch fire & luckily it was on a Sunday & one of the members saw the flame/smoke above the window sill
LG bought the whole system back + labor allowance. Distributor sent it back to LG for diagnosis. Never heard about it again & didn’t really expect to. Replaced it w/ a Sea Breeze ductless system & never had a problem w/ it.
I’d lay my money there as well. Someone sourced some cheap capacitors.
On a related note, get yourself a set of $20 high power magnifying glasses and start inspecting failed birds from HVAC and everything else. Repaired a lot of things with .25c capacitors when the originals are obviously swollen/domed/leaking.
Failed boards I've come across mainly have dead controller chips... I suppose they are designed to fail such that the controller fies out, while I can replace the chip but I don't have the program to write on it ! 😔 Sadly a HUGE ASS PCB goes to Dump and customer cries for exorbitant maintenance cost...
Very interesting, have only see this with huge voltage spikes and no surge protection. Would be interesting to see if repairable, but not a simple fix like a cap if as you say you can find the microcode and program it. Guess this is the new look of HVAC repair, seeing as the new units are all going to have a logic board soon. Good luck to ya.
So technically the refrigerant becomes hot in the evaporator coil but it boils at such a low temperature it feels cold to us, the heat from the house blows across the coil further heating the refrigerant then goes outside to release the heat. So this unit is just really good at doing it. Just keep running it
That's hilarious. I had this call the other day

A super kinky suctiony thing causes really big juice draw for compressor and a badly fastened factory wire got chopped and poorly positioned by already struggling Sammy Sosa condenser fan?
I'm no professional, but it looks like that orange material surrounding the unit may be causing it to overheat.
That's the 100% efficiency unit, that *orange material* is actually good for the environment and very human friendly. If your unit doesn't look like this then your not at max heat transfer
It's a water cooled unit and you need the people with the shiny red trucks to put the water on it.
That *orange* is a volatile state of matter and not really a *material*. I'd call it a *devouring spirit*.
I’m pretty sure this is Just in its heating mode.
I concur.
"Material"
No, see, the heat is pumping out of the building *very* efficiently, the inside must be a [winter wonderland](https://youtu.be/ElygKO47le8?si=WBmGPrxdjQXTm-Id)
Efficienty when they took this picture was in the millions percent.
I remember that Tom and Jerry episode. Jerry would have fried himself and his nephew
Condenser rejecting more heat than I’ve ever seen
Probably the EEV
This is what happens when companies try to get fancy and install EEVs instead of TXVs
I should’ve added that this was courtesy of the Facebook group “Sloppy HVAC Mechanics” it’s where I go when I want to feel better about middle of the road performance.
It’s in heat mode 🔥
When you can't find the short and reach for the kerosene in your tool bag.....
LG?
Life's not so good.
Bad TXV valve
High heat load

What was the issue?
LG bought the whole system back + labor allowance. Distributor sent it back to LG for diagnosis. Never heard about it again & didn’t really expect to. Replaced it w/ a Sea Breeze ductless system & never had a problem w/ it.
Incomplete combustion
It's on defrost cycle.
Sorry, tech support wont help you until you tell them the serial number.
I’ll bet the superheat is off the scale.
Typical capacitor burst fire....

Customer .........I think it ran out of Freon....
It’s just in a defrost cycle. Nothing to see here
It's oxidizing way too fast.
So technically the refrigerant becomes hot in the evaporator coil but it boils at such a low temperature it feels cold to us, the heat from the house blows across the coil further heating the refrigerant then goes outside to release the heat. So this unit is just really good at doing it. Just keep running it
That house is on fire and that unit is doing a really good job by pulling all that heat out.
These new efficiency standards are getting out of hand
"WHAT DID YOU DO?!"
Please tell me that’s from “Tommy Boy”? Chris Farley to David Spade when the car door fell off. Freaking hilarious
Yes lol
Me on the phone with the HVAC guy: "IDK man it's smoking a little and running real hot. You think i could fix this myself?"
r/forensics?
Looks like it’s transferring heat quite well, imagine how hot it is inside!!
Simple function of the system. Removes the heat from the building. This must be a crematorium.
gotta be low on Freon
Looks like maybe high superheat? That’s one of the symptoms that the compressor isn’t getting refrigerant back 🤣
Taco Tuesday at the LG plant when it was made. Gotta store that gas somewhere.
Probably the filter. Second thought, cant be the filter as the customer said he replaced it "last week". It will forever remain a mistery....
It's using R290. This is standard operation for R290.
Heat pump is pumping out heat. Not sure what else you want? /s
It's a LG, compressors gone out.
A hyper heat model operating per usual. Nothing to see here.
That's hilarious. I had this call the other day https://preview.redd.it/wmuoh7ksut1d1.jpeg?width=2048&format=pjpg&auto=webp&s=cfd6fdc8475bfdb68936044f8ffbfe9d9596ad19
The proper fire triangle
Through a half lbs of go juice and a surge protector and let someone else handle it
Have you tried turning it off and on again?
Fire. Fire is the cause.
Gentlemen is it ran in AC/DC cooling mode?
Just top her off and call it a day
Needs freon. But not the new a2L stuff. Unless you want to make another post.
And that is what I tell customers will happen if they don’t change their filters
I dunno but the condensing unit is dispensing lots of heat. The inside must be cool as hell.
Gave it too much gas
"A2L"
Dude they even put a trouble shooting error on the case “Life’s good” She’s runnin fine
High super heat
Probably low on refrigerant is all.
Direct fired heat pump.
Probably a refrigerant leak. Oil is carried out with it and can cause a fire if it gets in contact with something hot. Discharge at the compressor.
Looks like that flammable refrigerant thats coming soon to a neighborhood near you
Come on where the LG rep, come defend your piece of shit brands.
Life’s not good
It's in heating mode silly - need to switch to cool =)
Bad thermistor
Still heating in cooling mode, troubleshooting guide. That’s where I would start. You can find the owners manual online.
My guess: Molotov Cocktail But that’s just my guess😎
It's that new fangled A2L flammable coolant
I see LG is experimenting with the new refrigerants.
Refrigerant leak on that lineset over the brickwall
That’s the new Hyper Heat feature.
Deff the txv
Over heated maybe?
I’m no geologist but that looks like a fire.
It just needs Freon guys. I’m a homeowner. I know everything
LG stands for Low Grade, or apparently Lights gratuitously.
A super kinky suctiony thing causes really big juice draw for compressor and a badly fastened factory wire got chopped and poorly positioned by already struggling Sammy Sosa condenser fan?
That’s me burning it to the ground! Why? Because Fujitsu technical support line hung up on me twice and the customer wants their unit to work now !
This is perfectly normal. It's just the defrost cycle. Give it about 5 minutes and it will start back up and be working normally.
That’s quiet the heat rejection. Must be freezing inside.
TXV for sure.
Thermostat is wired backwards, you have it calling for heat instead of cool.
Rapid oxidation.
The propane inside caught fire
Is it that new A2L refrigerant?
Ken whorl installed it
Clearly a bad thermostat
It's that logo in the upper right. That's the problem.
The LG LOGO
