The rarely used aircon in the lounge won't turn off. The compressor does but not the cassette or whatever it's called that has the fan inside the room. The technician says it needs a new control board or something that costs around 3000 baht. Does that seem about right? He replaced something that sounds like a capacitor and regassed the compressor and replaced a globe that lights up when the aircon is running for 1400 baht.
It was a Panasonic, couldn't tell you the model #. This was in Australia over 25 years ago. In fact I still have a Panasonic plasma 50" that I bought when I arrived in Thailand 14 years ago. Never gets used though.
