Thought the capacitor trick for my garage door opener was internet nonsense until it worked
My 1998 Liftmaster opener quit responding last month and every forum post said it was the logic board, which runs about $95 if you can even find one. Then a guy in a garage door thread said to check the electrolytic capacitor on the board first, so I pulled it and sure enough the top was bulging. Swapped in a $2.40 cap from a local electronics shop in Spokane and the thing has opened my door 40 times since with no issues. Now I'm wondering how much other "dead" gear I've thrown out over the years when it was one cheap part. What's the oldest piece of hardware you've brought back with a component swap?

That Spokane shop detail got me. I used to be the guy who just replaced the whole board without even looking at the old one, figured a $2 cap swap was just something old radio guys did to feel smart. Then I fixed a 2004 treadmill that way, a $3 cap on the motor control board, and it still runs. Now I pull the board and look for a bulging top before I spend anything. It's saved me a few hundred bucks and a lot of trash.
