A microwave is an essential kitchen appliance, but like any other, it can wear out over time. There are steps you can take to extend its lifespan and avoid frequent repairs. First, clean the microwave regularly to prevent food buildup and stains, as this can cause damage to the interior and affect its performance. Always cover food when microwaving to prevent splattering, which can lead to grease buildup inside. If your microwave is making strange noises or not heating food evenly, it may be a sign of a malfunctioning magnetron or turntable, both of which need professional attention. Additionally, keep the door seals in good condition to avoid energy loss and ensure that the microwave runs efficiently.
