Question about Fujitsu 24C1 Air Conditioner
I have same problem like yours to my newlyinstalled Fujitsu multi-split system (the first time use since system installed1 week ago). I rang the electrician whodid the installation; he said it must be the units themselves nothing to dowith electricity. Okay, then I rang Fujitsu and their local service agent. Theysuggested me to switch off C/B for an hour to reset the units. I followed theinstruction but the indoor units still did not respond to remote control...
It simply looks like no power supply to indoor units (they are hard-wired tothe outdoor unit). So I used a multi-meter to test the power terminals of indoorunits (Danger! If you have no idea about this, don't even try! ): it seemed nopower supply even C/B is on. I turned to the isolator which next to the outdoorunit. The isolator was making arcing noise when I switched it on and off. Theindoor units suddenly turned on for few minutes then died again. So I figuredout the problem is that crooked isolator. I called the unhappy electricianto replace the isolator. End story.... I hope my experience will give a littlehelp to you...
