Hi All, One of my Fujitsu inverter air con is not working. It can't be turned on by the remote control, but it is working properly if i press the On/Off button from the aircon. The remote control is working fine because it is functioning well if i use to turn ON on my other fujitsu aircon. Has anyone experience this? And i read about the bad review on Winfinity. any suggestion on better servicing company? Thank you
