I've been asked to look at a FUJI 9K Inverter ROR09LCC. I'm presuming FUJI's are linked to Fujitsu. Going off the indicator flashes, its highlighting a Voltage Trip.
After switching power off and on, Outdoor unit starts the fan for 1 second and then stops, Compressor doesn't try to kick in.
There is a click, I'm presuming from a relay on the PCB when the fan switches off.
As luck would have it, my clients had the same unit next to it and so I switched boards and it seemed to work ok for at least 30mins.
Put everything back together including the indoor unit that I'd pulled apart. Went to check it was still running........ No, original fault back.
Swapped the board back and its causing the same fault on the one that was originally working and so I have two units not working at the moment.
Any one with any suggestions
