So I had a daikin 4MXM80 multisplit. After a month 1 room didnt work (valve didnt open). Placed a new motherboard, which blew up a month after installing. Daikin didnt want to send new motherboard under warranty. We decided to buy a new outdoor unit. (4000 euro). And after a month the new one had the same problem, just different room. Now all the sudden Daikin admid that it is a common problem on the MXM series, due to "too low voltage going to the magnets". They will send a new motherboard. Not sure if that is the problem, or if the pins just get stuck. Just FYI so you know :)
We have exactly the same problem with the 4MXM68A. Been going on for 2 years now. They replaced the motherboard a month ago. We thought it was solved but this week one unit failed again. So changing the motherboard did not solve the issue. My guess is that the magnetic valves are just prone to get stuck over time.
Love this sort of content. Gonna share with the lads at work to help them get a better understanding. Any chance of future vids of similar nature for other components? Your explanations are a lot better than fault finding from a book!
Thanks mate. Yeah that’s the plan, I’ve made a playlist called Daikin training where I plan to do a video for each component in an air conditioner. I’m no expert, I’m just making videos that I wish I had when I was learning. There will definitely be more videos of this nature. Cheers
Professor, if you could please explain to us a video about the closed electric expansion valve, which carries the model EX7-121 from the working company Amrison, the method of connecting it to the driver, its maintenance, and its problems. I thank you for your cooperation. We greatly appreciate it.
Hi Mitch have you ever tried getting boards repaired I have always thought it crazy that we have to replace a complete board when I assume all they need is a component ie processor or something. I have tried but had no luck.
@@declankearney9353 I’ve taken a board out that was no longer available and taken it to a repairer who did actually repair it but after it was reinstalled, a different fault came up. I personally think it’s too risky trying to repair because a component failure can take out another component and you won’t know until you turn it on. Also if it’s a Daikin processor that’s faulty, the repairer won’t carry those parts unfortunately. I just think manufacturers need to make more durable boards but I do know what you mean.
@@maracservices (I'm homeoner myself, so I may not have a lot of information about this) However, I did see them in the R22 system (2012) and the new R32 system (2-3 years ago) and plus the outdoor board issues. there is a video link here: watch?v=Zk4Ku284cPU timestamp: 5:01 is the capacitor that failed in the inverter board (compressor cannot run/cutoff at high speed/ramping up) 10:40 is the rusting EEV And there are lots of video showing how to change the capacitor on the inverter board by technician and homeowner, that speak the number of how many of them failed.
Please watch Craig at Ac service tech...I have high hopes you can do better like him for our side of things ..a smile and well tailored contents will take you there or else....

These videos are godsend for a tech who’s new to troubleshooting this type of equipment, thank you.
I see. Thank you.
Just recently, the EEV coil did not work and the copper tube was frozen.
Unfortunately, it was Daikin.
Superb explaining 💯
I am learning lot of things in this video thank you so much dear 🫶🫂✨I am sri lankan young boy i am ac technition sri
Thanks Mitch, that will be helpful to the new A/C tech guys learning out in the field 👍
My go to guy for all ac your the best bro
Thanks mate!

So answer me this, cousin. On the small solenoid, if readings being 45,46,46,46;
What would be considered bad ohm readings it were bad?
Thank you Mitch!

Great stuff as always. Thanks 👍🏼
Hey mate, Do you know resistances & voltage outputs required on a Reversing Valve solenoid coil on a Daikin Ducted 14kw
This was excellent content without the service facts manual you can use this as a rule of thumb
So this tells you if the windings in the eev is good?
I've subscribed as well as I have faith in you.
Can you put a video using the EEV tester magnet
DAIKIN part # 99S0038
Thank you, useful info.
Very good tnx info
Just wonder, have you seen any rust problem on the EEV motor part (the whole black thing)
Can’t say I’ve ever seen rust issues with them mate. Have you? I’m curious!
@@maracservices (I'm homeoner myself, so I may not have a lot of information about this) However, I did see them in the R22 system (2012) and the new R32 system (2-3 years ago) and plus the outdoor board issues.
there is a video link here: watch?v=Zk4Ku284cPU
timestamp: 5:01 is the capacitor that failed in the inverter board (compressor cannot run/cutoff at high speed/ramping up)
10:40 is the rusting EEV
And there are lots of video showing how to change the capacitor on the inverter board by technician and homeowner, that speak the number of how many of them failed.
So what are the rest of rhe wires for!!
How often do you get bad eev
As a 30 year service tech can we just go back to the old style capacitor,contactor,control wire Y,W,G,R,C… A/C systems
Thank you very much ❤
Do you see these things failing much mate?
Very very rare in my opinion. But I always check them when I see a faulty board for piece of mind
@@maracservices Good to know. Thanks for the reply Mitch.
