Can't find Capacitor - will this work?

    I'm not an electronics guy - but pretty good at repairing stuff. Today I have a Kenmore Elite food processor (model 100.900027) that won't run (just hums). The motor start capacitor is bad. But can't find a replacement anywhere. The unit is 120VAC 60Hz.

    This is what it has in it now:
    "CD 60 Capacitor
    150uF +/- 15%
    175V-AC
    50Hz (60Hz)"
    It is about 1-1/4" Diameter and 2-3/8 Tall, cylindrical with two wire leads at one end.

    Best I can find is:
    "CD60 Motor Capacitor
    150uF
    either 125VAC, 220VAC, or 250VAC
    with spade terminals.

    Will the difference in voltage be a problem? If not what is best choice (the 220VAC)?
    Thanks

    Here's a picture of it.

    As long as the voltage rating is equal or higher, and it fits it will work.

    Thanks. So the 220VAC is higher than the current 175V cap, so that is what I'll get.

    I saw a bunch of capacitors that matched mine more closely in size but the voltage was 450V. Is there some point where the voltage difference is just too high to work? Meaning is the 150uF 450V capacitor better than the 150uF 220V capacitor with all other things being equal (even though the motor its connected to is 120V 60Hz)?

    not really, its just the voltage rating of the capacitor. If its close to or below the voltage the circuit is operating at, then its likely to fail catastrophically ( BANG)
