It's an old Sears garage door opener. The schematic shows a 50 ufd start
capacitor. What's in there now is 43-52 ufd. What I've found locall to
replace it is 53-64 ufd. Will that work?
YES
Those values are not critical for that application.
Right. A start capacitor has a minimum value at which it work work.
The ones that are critical are the run capacitors. And even then,
10-20% will usually work, 100% might, but the motor will run hot.
