If the main compartment in your refrigerator is too warm or too cold and adjusting the temperature controls doesn’t seem to help, you will risk getting your products spoiled soon. First of all you can vacuum the compressor and condenser coils. If they aren’t cleaned a couple times a year, the refrigerator won’t be efficient. If dirty coils aren’t the problem, check and reset the temperature in the food compartment. It should be between 35 and 40 degrees Fahrenheit. A freezer should be between 0 to 5 degrees Fahrenheit. Most of the time, when faced with a refrigerator not cooling, one of the main parts needs replacement. Replacing these specialty parts should only be done by a licensed worker, so if you’re in that situation, call a pro.
