Cultus euro 2 (2013) uses 15amp fuse for A/C, this fuse got burn and melted which damaged its portion. I replaced it with a 15A fuse 2 to 3 times but it shorts again and again. I then replaced it with a 20 amp fuse. Its working fine till now.
So is it dangerous to install 20 amp fuse instead of 15 amp and what could be the problem.
