Towards end of the dinner on sun night, I saw sparks nearby my living room air con and the unit black out. At first I thought as long as I switch back on the main "fuse" panel, everything would be back to normal. But no response. My bf went around to turn on switches and he stepped on something mushy...o SHIT that's exactly what he had stepped on. Not to mention, he stepped on pee pee already in the morning. We tried to call some technician however they all said they are off work since it's around 10pm by then. Later, he asked his father and found out that there's another "fuse" panel outside the unit. And it worked finally.
on the following day, his dad came over to check. luckily it was just the swtich which has blown up.... and not the aircon
