suspecting old fan humming of old age (20 years+) , I bought new Panasonic 3-Blade Fan and installed according to manual.

but then when switched on, i can hear humming or 'woong woong woong ' sound .

the hook, the big rubber thing , screw all tight and nothing is loose vibrating.

is it the ceiling's hook is bad or?

4 other fan in my house, 2 is NEMC, one is kdk, one is panasonic (previous model) doesn't have this noise.

bought the new fan this monday only. 26 October.

since it is of old age (20 years+) , bearing needs some lubricant?

MISMan TS might refer to new fan, not the old fan

Check the blades are symmetrical (mounted properly)

Show close-up photos on fan.

You mean take a photo of fan?

seems to be common proble... my house have 4 panasonic fan. ...
most of them have have issue or have it repair before.

happen within a year or 2- due to capacitor board. - around 100 to replace the part + 80 service cost.
some other people also report same issue- just that seems like i am more bad luck

but for u- just within a week- try to ask them to check gua

plaster ceiling or concrete ceiling?
Usually this is caused by the hook senget thats why the fan wobling

Yes ...different angle shots will be good including the hook.

Em... not plaster or concrete .... the other kind... the fan doesn't wobble

In my experience, Panasonic have very good after sales support. Call up their helpline, they normally can send a technician over to check. (but dunno if this will be possible due to CMCO).

20 year old fan will have a speed oscillator? Set it to 5 and try again. New fan don't need an oscillator.

Whats speed oscillator?
I reused the old one electronic regulator , from national one too. Inside it have a big chunky thingy with copper wire .

Use the new regulator, the old one probably giving impure power to the fan like disco light. Capacitors in the regulator box tend to fail after 10 yrs.

why the earth wire not connected?
nanti kena electroFLYing when touch expose metal part of the fan

Humming change capacitor
