Many types of bacteria thrive in normal room temperatures, and it's only a matter of time before they contaminate food if you don't seal the food or place it inside the refrigerator; so, having no refrigerator in the house is as much a waste of food as it is a waste of natural resources.
Make sure, then, that your refrigerator is working in top condition by cleaning and maintaining it on a regular basis. You don't have to wash it everyday or even every week, but just often enough to keep the compartment clean and the refrigerator mechanisms running the way they should. Cleaning is done using a scrub and a small amount of mild soap (or baking soda) mixed with clean water. Defrost the machine, either by turning it off or setting the dial to defrost, and then leave the door open for a few minutes. Then, take out all the items and begin scrubbing the walls, floor and roof of the compartment. Don't forget the handles of the fridge and freezer and the seals that allow the refrigerator door to close air tight. Rinse several times if necessary, but it is recommended to use only as little detergent as possible so you won't have to rinse again and again.
Refrigerator Repairing, Troubleshooting
Do not try to repair a broken refrigerator if you don't know what you're doing. Tampering with it carelessly can cause more harm than good, Worse, you might end up damaging it beyond repair; then you'll be forced to buy a new one.
Check some things out before you make that call to a major appliance repair person. Is the refrigerator plugged into a working electrical socket? Is it only partially plugged in? Also, check the cord and the wiring. A frayed cord could be why the refrigerator isn't working.
Is the door closing properly? Are the seals still allowing the refrigerator to close with an air-tight seal? The seals are important to trap in the cold and avoid excess energy consumption. If your refrigerator isn't Energy Star compliant, you may want to just get a brand new or used one that is. The energy savings might be worth the cost of getting an updated refrigerator.
