Daikin indoor fan fluctuations

[BJ74]

Hi there,
Recently installed a Daikin ducted FDYQ160 - no zones. Indoor fan fluctuates every 5 -10 seconds quite noticeably. Weighed the refrigerant charge out an back in again - It was perfect. I have installed over 100 of these units and have never come across this fault...any ideas anyone ??
Cheers

first you have to check the capacitor,then the motor's windings and finally the pcb.

Hi Greek Engineer
Thanks for your reply. Just happened to be talking to another tech at work and he mentioned that he'd had the same problem on a wall hung unit. He Changed the capacitor and it solved the problem. I'll change it over and let you know how it goes.
