Nicely done Mitch, your a top A/C service man, looking after your valued customers.. Excellent camera work, super clear video in daylight, and the evening darkness 👍
Thank you! I try my best to look after the people who trust me to work on their homes.
Good on yah Mitch definetely had plenty of them days where you wake up for work when it’s dark and don’t finish work until it’s dark, all part of the trade 💪
Thanks so much mate. It was just one of those days. I agree it’s just part of being a service tech!
@@maracservices it’s all worth in the end when it finally works as it’s meant to be
I totally wig out when I get a call to somewhere I’ve just been….. my self doubt comes flooding in…. 🤯 overthinking everything….
Well handled mate 👍🏼💪🏼
Thanks mate, in this case I straight away thought the board was faulty. Straight away thinking the worst!
Haha, I think we are all like that 😂
hey big fella, remember the old daikin "service" app they updated and ruined? turns out if you log in up the top right (requires an email) you can get access to all the good step by step bsc buttons/ hp lights field settings. I recently had a vrv style split ducted that had this same fault, bit of a different story since the place just had 3 phase reconnected after going through flood. Had to run the thing through test mode before it would fire up. Keep cracking on mate love the vids
Ahh sweet thanks for that! I still have that app on my phone funnily enough. Good to know! Cheers
I so thought you were going to say there was a power surge when you said the power company had messed with the power. With big jobs like this if you have a sparky on the site consider getting them to add a power surge breaker in the switchboard.
Mate I was so nervous! I was thinking power surge too 🤦🏼♂️. I’ll definitely get a surge protector sorted. It’s a non negotiable for me from now on.
Always test what you’ve done when phases are re energized they don’t get re connected simultaneously, there’s a time gap between each phase connection and if phase 1 is connected first and the Daikin has control on its enough time to register u1 loss of phase. More often loss of phase than phase reversal. Massive issues for energy supplier if they start reversing consumer mains
Very interesting, thanks for that! I appreciate it mate and that all makes complete sense.
What happened in this video is complacency and assumptions from my part. I learn something new everyday it seems. I will say though, I have absolutely seen Aus grid reverse the phase when disconnecting and reconnecting. I’ve actually made a video on one. So my assumptions weren’t completely out of no where. Regardless thanks again mate!
@@maracservices yeah it definitely does happen but not frequently and can cause them big issues etc so they do try and do their best to avoid the headaches at the very least.
Nice repair Mitch. Was that “cage “ put around the condenser to stop a thief or for visual looks?
Thank you ! Honestly I’m not sure about the cage. It got put in after the install. I think it might be for the dogs incase they go down there because there is a drop off a bit further down.
Did you charge the customer for this mate? It's a tricky situation when these types of things happen aye
Unfortunately not mate. Like you said, it’s a tricky situation. The customer was very appreciative though and has already got another decent job for me so it was one I’m willing to wear. With all that being said, I actually put a percentage on top of these larger installs that allow for teething issues like this. So all good, everyone’s happy. 👍🏻
@@maracservices happens very often when your local energy company changes energy counter. They just replace it and it doesnt matter for em if its L1 L2 OR L3
I don't really know if client should be charged for it. But someone has to pay..
Hey Mitch, which one do you prefer Airtouch or my air? Or do you have a different one you like better? Iv only installed the airtouch so would like to know what everyone else is installing in the aircon world.
I’m definitely a MyAir guy. I’ve installed many of them. I’ve installed one air touch and didn’t like it but to be fair that was a few years ago so they may be better nowadays. I think it’s also important to note that all third party controllers that incorporate “smart” zones, wifi etc are all great and I have them in my home but they are also definitely not going to last 20 years. So I don’t push it towards customers who want reliability. But to answer your question, I prefer my air.
So ,you swapped firstly the white and blue and later you came back putting as it was before? or you swapped one of the white or blue with the red ? Can you please provide
thanks for the video - today was the first time using our Daikin AC 3 phase and just does not seem to be getting cold and pushed the test button and says U1. Ausgrid did change the lines to the house from 4 lines to 3. *Is it bad to run with a U1 error?
U1 means the phase has been reversed. It will not produce any cold air what so ever until it’s been rectified however you can still run the indoor fan fine.
I would turn the circuit breaker off for 15 patient minutes then turn it back on. If the fault code remains then you need a technician to change the phases around. If the fault disappears then you are good to go.
Thanks
@@maracservices thanks heaps for your advice, turned off the CB and waited and still happening - will try and get someone in before Christmas, thanks again
Nice job
So now the question is do you get paid or no ?
Are you like me and have dozens of apps and service manuals for dozens and dozens of systems?
Just wondering if its only me downloading a service pdf to find ive already downloaded it at some stage.
Yeah mate I’m all over the shop. I’m a bit old school to be honest and I have a folder in my car with a lot of Daikin stuff plus some notes I’ve written down from Daikin training days. On my phone I have the Daikin and Fujitsu apps. If I’m going to a service call I generally make sure I have that brands info on hand.
Hey mate just wondering if you know what possible could cause a8 error on a ducted daikin 16kw r32. Thanks
Thats an issue with the incoming power to the indoor fan motor from memory. Did it happen randomly? If so, first things first.. You need to turn the power off to the unit. Not just off at the controller but off at the isolator or circuit breaker and leave it off for 15 patient minutes minimum. Then turn it back on and see if the fault has cleared and if it happens again. cheers
Hi Mitch, our system shows that u1 error but we still get the cold air. Is that ok?
Thanks
With all respect, why on earth don't you carry a phase rotation tester? No idea what they cost there, but here GBP100-150 gets you a branded unit.
Im not perfect but trying to get better each and every day. I’ll definitely buy one. Cheers mate
Hey mitch, I got a job that also have a u1-01 fault but is a singer phase not a three phase, do you know what it mean? Is a Daikin thanks
It’s a power issue mate. I’d make sure the unit has power and if it does check for power on both sides of all the fuses located on the outdoor pcb.
Thanks mate, I will go check the fuse. I think the fuse is connected to the outdoor PCB that can't not replace might need to change the PCB
