When to get rid of microwave oven?

You should consider getting rid of your microwave oven if it shows signs of physical damage, such as a broken door or cracks, which can compromise safety. Additionally, if it begins to make unusual noises, emits sparks, or has a persistent odor, these could indicate malfunction. Lastly, if your microwave is more than 10 years old and not heating food evenly or efficiently, it may be time for an upgrade.
