it seems tht the problem is with the compressor of the refrigerator.
sometimes it happens that the "gas" in the compressor leakes off and ,tht gas is responsibale for the colling of the refrigerator.
so,either you can go for refilling of gas
or u can buy new compresssor of same rating as refregerator have.
my personla recommendation is to go for new compressor bcoz most of the time it happened to me that the customes complain abt the temperatures and some complain abt the leakage od gas again.
so,best option is to go for new compressor.
in case u hav any problem furthur just write me on my email
