Mitsubishi Ductless Split Shut Off on OverCurrent Faults 

You did everything you could. Looks to me like you are very good service technician so keep up the great work and I really like your videos

Mistsubishi in heat mode should be 415 psi at the ten minut to 12 minute mark from when the compressor turns on. If you hit those pressure at those times your charge is accurate. If you hit it sooner then the 10 to 12 minutes your over charged if you don’t reach that mark your refrigerant is low. Granted you don’t know how much over or under you are. But you will know one or the other

Great video. Excellent attitude to customers and trouble shooting

You are really putting out some good videos lately. The unfortunate thing is a lot installers do not now what the dip switch setting should be, on other Mitsubishi units a jumper wire needs to be cut for crankcase operation. All Mitsubishi units I sell is the Hyper Heat models, now you would think since these units are design for cold climates that they would automatically do this at the factory, the problem is that would lower the efficiency of the unit, and manufactures do not want to go down that path

Wow these are really clever units

Yes you have to be careful what you say to customers. Ive had them call the company to ensure what i was saying was correct. I try to keep it simple but informing as well showing what i find and why its not working properly. All u can do

Good troubleshooting vid Hackster ...

Wonder why that auto defrost got turned off? They are usually there for a reason. Kinda like a frost free fridge. If it isn’t defrosting as usual eventually it plugs with ice and quits working.

Great Trouble shooting !!!. I have LG unit only a few week old randomly shutting off no codes i found high voltage coming in @ 246 volts. Have a call in to the utility see what they can do

When you go to the roof what tools will you bring with you?

Nice educational videos man!!! I'm a fresh subscriber, and I have a question regarding the communication you have with the customer when you explain to them what the problem might be. I've seen couple of your videos, including this one. Out of curiosity, do you think that most of your customers understand the air conditioning terms when you are explaining it to them? Like for example on this video you brought up the TXV to the customer and it seemed that he knew what you were talking about.

Hello, L8 error code mean over current fault, what can i do for my unit.

Greetings from Michigan, I'm semi-retired with 45 + yrs in the HVAC industry & HVAC Instructor. I'm working as a ductless mini-split Technical Support representative for Thermocore. Systems. Love your down to earth approach on troubleshooting. Great job. I need to know what type of camera are you using for your video presentation. I'm blown away by the excellent resolution. Can you give me the info on the camera that you're using? Thanks.

Good Job

Geesh man those Mitsubishi units ain't no effin joke..I see more and more prob with those mini condensers...great efficiency but there badd if not maintained properly And something that's as complex as these inverter systems prob should be checked every 6 months...just to be sure Well nice job and catch bill....always great content...

You know your stuff when you put the lid back on top for air flow

I carry a 1” x 8” PVC tube to view LED’s in bright light - think of it like a periscope. Just hold the pvc over the led and look straight at it.

Good job on the explanation of the txv location and the refrigeration cycle to the customer. Alot of people don't realize how much customer interaction goes on in the hvac trade.

Nice video, check if the inside coil is clean or setpoint adjustment, low fan speed and high temp setting can cause this problem

Does the compressor have a crank case heater on it? Also I think the compressor has a 2 min delay on start up from heat to cool or other way? I don't know much about these units but why is the pvc chase with a 90 or 45 used on the line sets? I'm trying to learn about these units. Any help would be helpful. Thank you for this video, love to see more on them.

Bro I’m running into the same problem 10years after my install on a Mitsubishi

@guruMN, my Mitsubishi mini split heat pump is blinking 5 flashes. Is it the possible PC board? Condenser shuts down but after a few minutes it comes back on, only after about 3 hours did the error flash code come on. In a/c mode, unit is fine with the right amount of refrigerant. Any suggestions?

Between MHI and ME Splits which one is more reliable and durable according to your experience ? Thanks.

When a dual head split unit gets locked out from setting one on heat and one on cool. How do you get it out of lockout? Interior Units come on but exterior unit fan doesn't come on. Help please!

My outside compressor stopped running. Inside blowing like in fan mode on all settings - no lights flashing. I turned off and back on the outside unit multiple times - checked the breaker box and nothing changed - left the outside compressor switch off - went to work - came home and switched back on. Started the inside unit and guess what - the compressor came on! I read that leaving the outside compressor switch off for 30 minutes or so resets it. And now it seems to be working. Going to run it through the night. Its a Mr Slim Mitsubishi split air - 36000 Btu unit. I have the repair guys coming in 2 days to Replace the entire compressor - its will cost 6 grand and change to replace. Damn! We’ll see if it runs tonight and tomorrow!

The bug is in the board !!! Replace it ...

How u mount these and make them wind proof near ocean environment to flat epdm roof

Isn’t preheat on already from factory? So someone turned it off? Who the hell would do that?

How bad is an overcurrent? Doesn't the unit just throttle back to protect from the over current?

Do you know what can cause a air con room air conditioner to leak water out of the vent inside? Id hooked a shop vac up to drain line it seems to be draining fine cant see a drain pan don’t believe there is one but it only does it if im using ac the unit has a dehumidifier mode that cools aswell and it wont leak a drop

Hacker I love the video I want you to take a look at the Knipex StriX let me know what you think. Peace brother

Nothing worse than selling a part only to find the fault appears again in the future, Makes for a unhappy customer..

i assume thats inverter ac

I've never been a fan of variable speed hvac systems unless the variable speed is on a ceiling fan! Every home I have lived in had single speed and stage ac and gas furnaces, never felt temp swings with those systems! I think it is just a ploy to raise the cost of a product and push this environmental jargon! And those systems were cheaper and easier to repair!

I like your videos. I know the its tough to video while working but I wish the camera were showing what you're doing. Most of the time the camera isnt pointing at what youre doing.

It's interesting, I was noticing power usage on my mini split when it was off, about 35W and LG did a great job of not disclosing that information in any of the provided manuals. LG rep said it was done by passing current through compressor windings and would be active all the time. Yet I see it go off completely and sometimes draw like 15W, seems to be temperature regulated. Cheeky bastards praising their unit efficiency and hiding those important facts!

Nice trouble shooting video man

Good ol’ Mitsubishit mini-shit

You misspelled Mitsubishi

Katastrophe

wtf my my ac is in this video?????

cops comming you stealing there unit lol
