I have 9 years old Haier bottom mounted inverter refrigerator which is being used in a guest room. Couple of days back it suddenly stopped cooling completely. The Haier service guy came and checked and told that the cooling coil has leaked and needs to be replaced and would cost around 8K but he also added that it is not worth changing and asked to go for exchange as the refrigerator needs to be dismantled and the new coil needs to be welded back which is also very time consuming and few months later the problem may reoccur. Do I need to get another opinion as I am not sure if this service guy is interested in doing this job. I also asked him if it might be a oil leak or gas leak but he was just insisting that the coil needs to be changed. @blr_p what is your opinion?
