If the value of the capacitor on a motor is smaller, it can also be installed in other motors
The capacitance of this capacitor is so unstable that it can't be used!I hope my answer will help you.
The capacitance is ageing and the work is unstable and soon expires.I hope my answer will help you.
Don't keep using it. The capacity will continue to decrease until it is completely invalidated and has no value.
