Re: Is it possible to have Fujitsu inside units with Toshiba outside units?
One person on the roof one in the flat man on roof switches outdoors off in turn indoor fans go off that's your unit, saves climbing over that roof and don't London firms like a challenge !

If I switch off the power to the outside unit using the breaker the indoor fans will stop working? Do I understand correctly?
Re: Is it possible to have Fujitsu inside units with Toshiba outside units?
You need to know which unit you are switching off by the outdoor isolator

Correct because indoor power supply comes from interconnect wire which now has no power. Also remote control will go blank.
Regarding your other post, meggering is a way of proving resistance at higher voltages. You need a proper meter though. Otherwise disconnect wires off the compressor and measure resistance between the pins. Any two pins should give the same reading, only an ohm or three. Then try between any pin and earth. This is where you need the megger but if it's totally gone you might get a reading, anything other than open circuit on a normal meter means compressor is fubared.

What a fantastic piece of advice that finally solved the greatest riddle - location of my compressor!
Went up on the roof and identified it as unit #5!
I think at this point I will try to call in a specialist to identify and fix the issue.
Thank you for the amazing help and advice!

One extra piece of information: when I switched the breaker to off, and then back to on, it cut off all electricity in my flat.

More than likely your compressor is goosed

What a great read. Let us know how you get on.

All thanks to your help guys.
So I had a visit from an engineer, we were plugging off all indoor units one by one because he wanted to check if one of the indoors is causing the issue. But the error was always the same - 0:01
In the end he hasn't arrived at any conclusions, and kept going back to the theory that its one of indoors that could be causing the problem.
He wasn't able to say if any PCBs/fuses are blown and the fan motor wasn't checked.... in the recommendations he said that whole system, indoors + outdoor needs to be replaced.
I'd like to risk the route of fixing just the outdoor - unfortunately this model apparently is no longer produced so it'll be all down to spare parts availability....
...still waiting for the quote from the AirCon company.

I would try get a few diff quotes
Theres a company in London I can recommend. Danimak. You want to speak to Dan McDonald.

Hi Lucas,
Indoors have power and show no comms with outdoor, breaker was tripping. Therefore no need pratting about with indoor units, outdoor unit needs checking with ref to my post 36. The outdoors are complex but if you've a bit of experience some sort of conclusion should be reached. A decent check just of the outdoor would probably take an hour or two.
Bare minimum compressor needs meggering, outdoor power supplies on PCB confirmed, fan motor and inverter diode check be useful.
Cheers,
Andy.
