Before you channel your inner Bob Vila, safety first. Unplug the unit and flip the breaker—microwaves love hiding dangerous capacitors that could zap you faster than a bad first date. Wait at least five minutes for the internal capacitors to discharge. It’s the electrical equivalent of counting to ten before you scream at traffic.
Fun fact: early microwaves were called “Radaranges” and weighed over 750 pounds. Yours is probably a featherweight by comparison, but treat it with the respect of a cultural artifact. Wear gloves and goggles—broken glass from old bulbs is no one’s idea of a good time. Pro tip: place a towel on the floor to catch screws, dust bunnies, and your dignity.
