Using an old TV-style capacitor as a replacement for a failed motor capacitor in a 1 hp farm motor running on 220 AC is not advisable. Motor capacitors are bi-polar AC types, while TV capacitors are typically DC, making them incompatible. The appropriate replacement for a motor capacitor should fall within a range of 30 uF to 60 uF, depending on whether it is a start or run capacitor. New motor capacitors are relatively inexpensive, typically under $20, and using the correct part is crucial to avoid future failures and potential hazards, such as explosions or fires from incorrect capacitor use. It is emphasized that attempting to use a DC capacitor in an AC application is dangerous and should not be pursued.
