It was observed that the condenser was made of Aluminium. If the condenser is bad there is no point in buying inverter AC. I cannot use copper condenser as per discussion with Sharp technical department. The Sharp doesnot give warranty on Electronics circuit which is the heart of AC. The replacement on electronics circuit is very expensive.
There is no expert in India to repair inverter AC. Gas leakage is the main problem with this AC. All inverter ACs are use and through type.
