Thanks for the video, and especially highlighting the troubleshooting. I'm an Electrical Contractor for 50 years, and now semi-retired, I help friends & family with their mini splits. Your videos have kept me out of trouble many times.

Nice work, I like your troubleshooting technique. Must say I’ve never had the pleasure of a short sleeved no heat call on a rooftop in February.

[@vicenterivera69]

I like how you work. Super chill! My style also

[@sharky5570]

Got lucky on the placement of those boards in condenser. Usually they are upside down and a pia to get to. Great stuff Super Dave

[@camiloramirez3367]

Keep up the great work man, just one thing to add: between S2-S3 you’re reading DC Voltage, fluctuation between 10-32VDC means properly communicating ODU-IDU.

[@danwittels5542]

I was diggin' that disconect too. I never seen one like that before, perfect for a condenser on a roof. I've got to look for those.

always spend some extra on a good disconnect with plugs. its so nice for the next guy, because the next guy is probably you.

I'm in an entirely different field (I mainly do gas appliance repair) and my tool bag tips over all the time like yours lol

[@awesomebillfromdawsonville8715]

I hate those micro inline pumps. Stopped using them due to premature failure causing high temperature alarm in small server rooms. We use external mounted one piece mini split pumps easier to maintenance and repair. Another useful idea to keep door screws from getting lost I carry collapsing magnetic tray in my service bag. Craftsman and Matco have them available work awesome. I got tip from HVAC UK video 👍

[@MrBdogg317]

I agree we now use the aspen pumps that mount on the outside. Sooooo much better

[@SchwaAlien]

We’ve got an older Mitsubishi mini split AC in an artist studio that just drains outside by gravity and tends to build up ice in the drain pan and then leaks into the room. The building doesn’t allow permanent AC installation anymore, ours is grandfathered and we supposedly aren’t allowed to replace it, but it would be nice if they would make an exception and recognize the environmental benefits of the energy efficiency advantages of us upgrading it to a heat pump instead of just using an electric baseboard heater in the relatively mild winters we get in Vancouver... I was able to air heat the place with 700 watts of continuous crypto mining, not quietly but it wasn’t toooo bad for a couple winters as a productive alternative to the baseboard.

Should of just checked voltage across L1 and L2 at the wall mount and if you have voltage there then the problem isnt at the condenser.

Hi super Dave I work on ice machine and small reach in refrigerator and freezer, I have a question in regards to critical charge systems, I use 36" hose, let's say the ice machine said to put in 15oz of 404A, how much should I put in exactly 15oz or do I go to 16-17 oz because when you remove your hoses you're losing some refrigerant, also how much in ounce refrigerant does each hose hold,for 36"hose and for 60" hose thanks.

[@NorCal-refrigeration]

I’ve herd 2oz per hose but never weighed it.

[@davejohnsonnola1536]

Purge your lines and set the tare weight on your scale before charging.

It’s code here. Service disconnect within 6 feet I don’t believe fuses are required you can use a non fused disconnect, but it’s always a fused installed.

[@Abrokadabro]

@@NorCal-refrigeration ok so you have a main fuse in the subox then you have a fuse next to the outside unit if it's three phase power do you still have fuse at the outside unit and does it loses all turn off if you lose a phase at the outside unit disconnect switch
