Been a while since i wrote something here. Anyways, just to share, one of our aircon unit broke down not long ago and i went into panic mode. Scouring the internet for answers from people whom might have had similar issue but found nothing much.
So here's what happened. My Aircon, a Mitsubishi Inverter, just turned off by itself right after being switched on. After which 2 intermittent LEDs indicator kept flashing. I tried calling a few aircon service contractors and all of them told me its the PCB board is faulty and the replacement will cost about $300 to $350. (DAFUQ!)
Not wanting to give in, i tried calling Mitusbishi Electric and they immediately told me it is either the PCB Board OR the Thermister (something that has got to do with the temperature sensor). Well now at least there's other possibilities besides $300 gone.
Few days later, their guys came down and it was indeed the thermister. And how much did the replacement part cost me? $15. Yeap $15. Well of course they had to charge my for their transportation fee as well but that is just a fraction of the freaking $300 independent contractors were quoting me.
Phew!
