Get a fan expert from kdk to check the fans. Mostly normal electricians will not ground the wiring properly. Another problem is the clip that they forget to remove b4 finish installation.

Call the service center and pay the fees, kdk can last more than 10 years.

3 of my 6 kdk had this problem. besides humming noise, fan speed also affected. 3 speeds became 2. Speed 1 was ok, speed 2 was about 70% what it used to be and that was the fastest it could go. fan will beep pressing 3 on the remote but speed didn't increase.

for me, changing capacitors fixed the problem on those 3 fans. my fan pcb has 5 caps and a set of them costs around RM 10 on shopee. another option is to change the entire pcb if you don't want to solder but each board costs around RM 40 - 80 depending models.

hope this helps.
