Question about Fujitsu Heating & Cooling

Open Question

FUJITSU AST17RSA-W. Motor stays on when I turn it off.

The unit is a Fujitsu AST17RSA-W split system installed in 1997. When I turn the unit off with the remote control, the unit appears to turn off, and the heating stops, but the compressor motor keeps running. I can hear it whirring softly. When I came home yesterday the bottom vent was covered in water drops. This was after it was run on heating in the morning for a few hours. I had to turn it off at the wall to stop the motor running, and then the unit gave a big "sigh". Is there a way to reset the unit myself? Thanks.

SOURCE: Fujitsu mini split outdoor unit not running, but indoor unit is running after turnning on

Check the disconnect switch and make sure that both the fuses are good and not shot. If one is shot then the system wont work. There are two fuse. Also be careful due to you will be working around 210 volts

SOURCE: drain line obstructed Fujitsu split unit aircon model ASA12ASHTW

The best way to clear the drain line is by using a shop vac and sucking out the blockage and the water. This will make sure all the goop in there comes out. Let me know if you need anything else.

I came across a brand new Fujitsu Split System out door unit (AOTR24JCC), so Im look for the indoor unit (ASTA24JCC) Where can I find one? Thanks


Model is over 5 years old so unlikely to get a new one. However, the outdoor units fail while the indoor is good so check eBay or your local installer.

Remote control functioning unit is functioning, but remote control is not activating unit, could you please help. Part number is 9365005019.fujitsu room split air coditioner


Hi Russell Webe, just a guess, but sounds as though the remote receiver board is faulty, however you might try new batteries in the remote first,it may help. failing that it is time to call the serviceman. Also try turning the power off to the Ac unit for about 5 minutes and then back on again. This will reset the electronics and again may solve your problem regards. col www.digitalcontrols.com.au

Have model ASTB24LDC/AOTS24LDC Inverter Fujitsu split system. As of Thursday 11th Nov, unit stopped working. Won't respond with remote. An electrician came to test it this morning, says there is power to...


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...

Look, if you select a temperature above ambient temperature, it will switch from cooling to heating.(assuming that the aircon has a heat pump. most do these days.) Just dont rush the aircon because every time you make a setting change, it takes a while to regulate.
