The beeper on my 41 yr old Microwave died a few years back during a thunderstorm. It was like a dream come true.
The timer display. Although if you listen really closely you can still hear it try to beep, but you have to be standing right next to it in a quiet room.
I was just joking microwave owens usualy are loud as fuck. And Then they add a loud BEEP like you didn’t hear the jet engine shut down aaargh + new BEEP every 30 seconds too for sure.
