Do microwave ovens get weaker with age?

Something that used to take about 40 seconds to warm up in our microwave oven to a certain temperature now seems to take about 50 seconds. This change seemed to happen fairly suddenly rather than gradually. I don't mind waiting 10 extra seconds, but I'm wondering whether the power of a microwave oven diminishes over time and whether I should expect further deterioration of its performance. It's probably about eight years old and is used daily but lightly.
