Looks properly into the blade..
U might find that the blade is sticking dust already..

Most probably is cooking oil smoke or some other smoke like burning of incense oil accumulate at the dust on the blade..

So when u open the aircond, the roller blade roll fast and swing out those oil accumulated from the dust.. hence got those oil spot.

Ur aircond is using cool mode right? Not dry mode..
Cool mode easy to see water condensation, hence easy makan dust

Bukan mold ka tu

Is time to service the aircon.


Probably alot dead 🪳 inside

Maybe lizard go inside and get splattered by fan

No

My previous Panasonic Inverter also got this stain, I was thinking was it stain from cockroach or what? The aircond 4th year starting not cold, first replaced compressor under warranty, after few months not cold again they suspect somewhere leaked, top up gas 1 month then not cold again. Just barely over 5 years then I have to replace the aircond...

It’s the condensation mixed with dirt from inside the condenser

my current air cond do have problem. initially it is blowing cold air, but after 5-10 minutes, it will stop, as if it has reached the desired temperature. after sometime, it will blow cold air again, and this cycle repeats. outdoor unit fan is running well. I order a new indoor unit temperature sensor. hope it will fix the issue.

using remote diagnos error code

definitely the moisture + dirt + dust. Passed experience cleaning it DIY, using soap water mixture, spray it inside after open the filter for cleaning.

or TS, call service for AC cleaning. after cleaning, sure cold as new back, especially after clean the blower area from dust
