Thank you for posting this video. It saved me $15,000! I had a local HVAC company come out and they charged me $200 to say my unit was fried and I needed a whole new install. Thanks to your video I tried replacing the probes myself and... it works now!
Nice to hear that.👍👍👍
Hi there! We are having the same problem. Can you let me know where you found the actual parts. I've been looking everywhere, with no luck.
I bought the two parts and the technician replaced them. It solved the issue. Thanks again for saving me so much money.
👍👍
Hello @doronzemach3959 can you let us know where you bought this part?
Thank you for posting!! One service company wanted to replace my entire unit. Called in another company - mentioned these two parts from your video and they agreed that was the problem. Saved me a lot of money!!
👍👍
Great job. With these minis, it was nice you identified the parts where they were located. In those tight compact units its sometimes hard to see where things are located. Good camera work.
Thanks
Bon,
A lot of misunderstanding on inverter/ mini split style units here in the US- nice to see a channel that addresses troubleshooting and repair with these with more than just “replace the outdoor unit” mentality.
Thanks
I just wish in my country we had that luxury!!!!! A 3 way multi split outdoor unit is not a cheap thing!!!! Most probably in my country costs over 2K!
2 weeks ago i went to diagnose an air conditioner,outdoor pcb board was the culprit. (18kbtu hitachi inverter split unit,Not more tham 4 years old) Called local hitachi authorized seller and quoted me that the replacement outdoor pcb board is 600$!!! not including labour!!!! As soon as i told the customer, he told me replace the hole thing. a brand new 18k gree with 5 year warranty only costed him 900$. but by the way thanks a lot Bon for sharing your experiences.

Hi Bon. This is an excellent video, very informative.You explain things very clearly and thoroughly, step by step. My question is I have the same 7 6 error code but a different model number than the one in your video. Is my issue the same? My model number is AOU24RLXFZ. Thank you for your help.
Should be the same
@@BonMj Great! Thank you so much! I really appreciate your help!

Welcome
Hi, thanks for your video, very interesting. I have an identical unit that stopped working tonight. I have traced the power back to the head unit but no lights on head unit. Remote is working correctly on other unit. Head unit start no go. Is it likely to be the small 3.15amp fuse on the PCB in the head unit? Do you know what would cause it to blow. Many thanks.
May be cause by Fcu fan motor
U da man
Thnxx u Sir
Thanks
This video is incredibly helpful. We are having the same problem. Do you have a link to a website where we can buy the 3 way thermistor and 2 way thermistor? I have been searching for 2 days now, and can't find the part number or anywhere that sells the part.
Contact nearest Fujitsu

Can we bypass the 4 way valve in Fujitsu , can you please tell about the 4 way valve error .
This 2 way and 3 way valve thermistor- is only thermistor, not valve.
4way valve is different,4way valve is heat and cold exchange valve
I like to joing with you sir

@@BonMj i like to learn mitsubishi vrf.your kowledge is best
Could use some help. I have three heads... two wall units and one ceiling cassette. The ceiling cassette blinks green x3. No other lights just 3 blinks then maybe 15seconds of nothing.
I cannot find any error list that this aligna with. Units are blowing warm. I assume I have a slow leak but want to understand what 3 green blinks mean before I call someone out to recharge it.
Reverse comms fail in use
@Bon Mj yeah that's what i was finding as the error code too. Does it make sense that only one unit is blinking and the system isn't cooling? I would think the other two units would still be working and blowing cold? Or does the one unit bring down the whole system?
Please I need help on AOTG45LATL fugitsu duct ac the outdoor running for 10mins and cuts out..why is that? And there's no error code appearing on control screen and outdoor error led not giving any sign..
Compressor working?

I just replace the valve thermistor C and D, and the unit wont turn on. I've reset the power multiple times, nothing seems to work. Help!!
Do you check other thermistor reading
@@BonMj yes I did and one of the 3-way thermistor was bad, in addition it turned out one of the fuse (250V 10A) blown out. I replaced the fuse and reset the power and all working like a charm again. Thank you so much!
