Hi! Mr Jestine Yong.
Thank you Mr Jestine Yong for your kindness and patience to ensure that I can repair my Panasonic fan. You really save alot of my RM in my pocket if I can repair my two fans. Today, I brought one of the two PCBAs to office and check the big black Capacitors (3x) and the small Mylar Capacitors (2x).
I found that the 3 big black Caps were o.k and the 2 small Mylar Caps had very low Capacitance. The picture of the Caps and PCBA are in the attachment below:
