What should I do? Does this mean this microwave is taking a
well-deserved retirement?

Before throwing it out, I think I'd check the interlock switch for the door,
and make sure it's working properly. You might have a bit of food caught in
there that's preventing the switch from closing. or perhaps the switch has
failed.
