7. Inspect the Gaskets
Refrigerator gaskets are the rubber seals that line the door of your fridge. These seals prevent cold air from escaping and warm air from entering your fridge. Functioning gaskets are critical for maintaining the efficiency of your appliance and keeping food fresh. When cleaning the interior of your refrigerator, also clean the gaskets with soap and water. A toothbrush can be a useful tool for scrubbing away gunk within the folds of the rubber seal. Green Living Ideas suggests testing the seal on your refrigerator door by shutting the door on a dollar bill and gently pulling to check for resistance.
6. Vacuum the Coils Regularly
Dust, debris, and pet dander can build up on your refrigerator coils. This buildup decreases the efficiency of your appliance. When the coils become dirty, your refrigerator has to work harder to maintain the cool temperatures needed to keep your perishables safe. Bob Vila advises cleaning these coils at least once a year. If you have pets in your home, you may want to take care of this task twice a year. First, unplug your fridge before locating the coils. Then, while wearing a dust mask, vacuum the debris that has gathered on the coils.
5. Cover Refrigerated Foods
Before placing food in the refrigerator, make sure to package the items in airtight containers. Placing open containers in the refrigerator allows moisture and condensation to escape into the air. Forcing your refrigerator to expend extra energy to decrease the humidity levels can cause extra wear and tear on your motor. Additionally, placing piping hot foods into the fridge raises the temperature of the interior and causes your appliance to work harder. While you should place food in the fridge within one to two hours of serving it, wait until the food has cooled to room temperature.
