A microwave should typically be replaced when it reaches its expected lifespan of 9 to 10 years, or immediately if it exhibits critical safety hazards such as sparking inside the cabinet, a damaged door seal that leaks radiation, or an inability of the door latch to close securely. Other clear indicators that replacement is necessary include persistent burning smells during operation, failure to heat food despite the magnetron and turntable running, and recurring electrical control board failures that make repair costs exceed the price of a brand-new unit. Furthermore, if the interior cavity shows severe rust, structural degradation, or cracked glass trays that compromise hygiene and safety, upgrading to a modern, energy-efficient model is the most sensible course of action for household well-being.
