If your Samsung refrigerator is not functioning properly, then there are three ways to go about to fix the problem. The first one is to call Samsung customer care and ask them to send a repairer who can fix the issues found. The second way is to find a local repairer and get your refrigerator fixed by him. The final way is to do it yourself.
The first method is simple and is recommended for most people whose Samsung refrigerator is presently under warranty. In this case, a Samsung technician will come and fix your problem. If there are parts that need to be replaced and is covered under warranty, then you do not need to pay a cent. If the part is not covered under warranty, or is physically damaged, then it is an expense you have to bear.
If you are sure that the repair is going to cost you and you have a local repairer in mind, whom you think would be able to give you the best of services at reasonable price, then you can also ask him to fix your refrigerator. You should however remember that once an outsider, which includes yourself, repair your refrigerator, all future warranties, if applicable, will be void. With a professional fridge repairer, most of the parts he provides will be under warranty. These repairers are able to buy parts at cheaper prices, but most importantly, they will be able to fix your refrigeration problems without any headaches incurred by you.
