Washing machine motor capacitor question

[pilm89]

I have this GE/Hotpoint washing machine HTW240ASK6WS that uses a 60uF motor capacitor WH12X27614. The capacitor on GE's website is almost $100, which seems very expensive when I can buy a 60uF AC run capacitor for $10-$15. So I was going to do that, however I noticed the GE capacitor is actually a 60uF capacitor in series with a 60uH inductor, so it seems the GE capacitor isn't just a capacitor, but maybe a tuned circuit since 60uH is way too high to be parasitic inductance. Anyway familiar with this type of motor capacitor? I'd like to figure out if I can use a generic 60uF capacitor to replace the failed GE cap, or if that would be a bad idea. Thanks.

You could always use the old inductor with the new cap, if needed, assuming it is still OK condition?

The inductor might be there to reduce inrush current, but that is just a guess.

You could add an inductor in series with a standard 60 µF capacitor. They are not expensive:-

The impedance of the capacitor will be about 45 Ohms at 60 Hz, so you might get up to 3 A through it, so that inductor should be fine.

I have never come across a motor that had an inductor in series with the cap, after all, the start winding itself is a large inductor !?
Possibly an aid to create a closer 90deg shift'.
