In order to avoid a refrigerator repair you need to attend to it regularly providing the maintenance it requires. If it is a manually defrost fridge, you need to defrost it yourself regularly. When you see that ice on the inner walls of the freezer is about half an inch thick or more, you need to disconnect the fridge from the electricity source and let the ice melt. When that is done, you can plug it back and turn it on. In case you have a self-defrosting fridge, then maintenance is a lot much simpler than what has been mentioned for the manual version above.
If cooling pal breaks down then you do need to resort to refrigerator repair. It would be advisable to contract somebody specialized in the filed of refrigerator repair, as you may come across more complicated things than you expect though they be presented in the refrigerator instruction manual it came with. They say when you attempt to perform refrigerator repair yourself there are several things you need to do: discharge the capacitor and then disassemble your appliance.
Although instruction might seem simple at first reading, it might prove to be a little more difficult in reality. That is why it is recommended to have somebody trained in this field to come and carry out the troubleshooting and the fixing as such, even though a new bill is not something you haven't planned for the monthly budget. If you are still willing to try and troubleshoot or fix it yourself, the most important thing to do before you start anything else is unplug the appliance.
You will surely know that you need refrigerator repair as you will notice that your fridge fails in storing your food and drinks cold. The possible problem that the fridge might have can be related to many components so it should be highly challenging for somebody to try and carry out the repair alone without any appropriate training. There are very many things that require checking as part of the troubleshooting like the compressor motor, its relay or coils or fan, the defrost heater, its thermostat, the drain tube, the evaporator fan, the ice maker, the water inlet valve and so on. Sometimes you might simply need to place your fridge more carefully so that it is fully leveled.
In case leveling or defrosting does not work, then most probably your refrigerator repair will consist in disassembling the device and checking each of its operating components. Hopefully the bill will not be too big and the refrigerator repair will be done in a short time so that you will not have to add to that bill extra expenses brought about by the spoilage of the food you have already bought and stored in the now broken fridge.
