It. Had to be shown to local electician as the servicing man said thta the warranty only includes, repaiing of damaged parts and none of its parts are damaged. They have noyhing to do with its efficiency.
The local electrician charged me 2500to repair it. Its efficiency was food then for next two weeks but it now stopped working at all
