Why is the aircon switches OFF by itself and the aircon indicator light is blinking / flashing ?
The blinking / flashing of indicator light indicate that there is a fault with the air conditioning system. Hence the air conditioner switches off by itself. A qualified technician is needed to diagnose and repair the fault. As this is a protective function to prevent the air conditioner from further damage, it is not advisable to do a electrical power reset to get the aircon temporary working. Continue operation might further damage the air conditioning system.
