If you’re searching for the reason that your refrigerator has stopped cooling, the number of possible answers may surprise you. Refrigerators are complex machines, after all. Let’s have a look at some cases that may be truthful about your appliance. Most likely the breakdown is not really serious and you’ll be able to fix it yourself. Check the door latch first of all. If you see that it is broken, remove the latch. Use your drill and unscrew the screws in the latch as well as the screws on the inside door. As you remove the pieces, make sure you keep them all together—they are pretty small and can disappear quickly. Make sure the door gaskets are not overconsumed and unlock the door safely. Replacing these specialty parts should only be done by a licensed worker, so if you’re in that situation, call a pro.
