1. Put it in the right place
According to OnsiteGo.com, this is the key to ensuring your microwave lasts longer. Follow the instructions that indicate how far from the wall the microwave should be placed, taking into account the ventilation grilles of the appliance. As a general rule, according to OnsiteGo.com, you should keep all sides about 7 cm from the wall.
2. Clean it regularly
This is one of the easiest ways to prolong the longevity of the microwave oven. Unplug it and let it cool completely after using it, then clean the inside with a damp cloth. Once a week, place a teaspoon of vinegar in a bowl and heat it in the microwave for a minute or two. After turning off the oven, remove the turntable and wash it the same way you would with any dish. Also clean the inside with a damp cloth.
3. Always use the correct containers
This generally includes microwave-safe glass and ceramic dishes, and plastic containers specifically marked as microwave-safe. Avoid dishes with wooden handles or any utensil with metallic finish or paint. And remember, never use foil!
4. Take care of the door
Open and close gently. Knocking the oven door can cause a blown fuse, according to Repairclinic.com, since most ovens have up to three switches that must be closed in a particular order. This is only guaranteed when the door closes smoothly.
5. Use preprogrammed cooking times
These have been designed to be energy efficient and to give you the best cooking results. The use of preprogrammed times can prevent overcooking or burning food or splashing, which can damage the oven in the long term.
