A refrigerator is a major investment for your home, and you want it to last as long as possible. Most refrigerators run for 10 to 15 years, but regular care makes a real difference. Here are the habits that extend your appliance's life, lower its electricity use and help you waste less food.
Clean Your Refrigerator Regularly
Clean the inside (shelves and drawers) with a mixture of warm water and mild soap to prevent the buildup of grime and odours. The part most people forget is at the back or underneath: the condenser coils. When they are coated with dust, the fridge struggles to release heat, runs longer and wears out faster. Vacuum or brush the coils every 6 to 12 months (more often if you have pets), with the appliance unplugged.
Check the Door Seals
The door seals keep the temperature inside the appliance consistent. If they are worn or cracked, they let cold air escape and force the refrigerator to work harder. A quick test: close the door on a sheet of paper; if it slides out without any resistance, the seal is no longer tight enough. Clean the seals regularly and replace them if necessary.
Maintain a Consistent Temperature
The ideal refrigerator temperature is between 3 and 5 °C, with the freezer around -18 °C. A stable temperature avoids overloading the compressor and keeps your food out of the danger zone (above 5 °C). Avoid opening the door unnecessarily and let hot dishes cool before putting them away to limit fluctuations. If your fridge heats up abnormally or never stops running, it often points to a ventilation or setting problem.
Do Not Overload Your Refrigerator
It can be tempting to fill it to the brim, but overloading blocks air circulation and reduces the appliance's efficiency. Leave space between items, and also keep a few centimetres of clearance behind and above the unit so heat can escape properly.
Have Your Refrigerator Serviced
A check by a professional lets you inspect the components and catch problems early, before they get worse. When repairs become frequent or expensive, it is worth weighing their cost against a new appliance: our guide on whether to repair or replace your fridge helps you decide, and it pays to know whether your fridge is still under warranty before spending money.
A Well-Maintained Fridge Means Less Waste
A fridge that runs well and is set correctly keeps food fresh for longer, which cuts waste directly. Store items in the right spot, keep an eye on dates and freeze what you will not eat in time: many foods (bread, meat, fruit and vegetables) freeze well as long as they are wrapped properly to avoid freezer burn. Getting more life out of the food you buy is one of the simplest ways to reduce household waste.
Conclusion
Extending your refrigerator's life takes no complicated effort: clean coils, sound door seals, a stable temperature between 3 and 5 °C and sensible loading are enough to gain years of service and save energy. When the appliance truly reaches the end of its life, remember to recycle it properly in Switzerland rather than throwing it away.
