Running capacitor
Took the cover off my Crosley air conditioner to find out why the compressor
motor was tripping its thermal overload a few seconds after kicking on. The dual section running capacitor had a strange, twisty, grayish glob coming out of its side. The stuff looked like one of those "snakes" that the kids light on July 4th, but is was very hard and stuck tightly to the capacitor body. Pried it off. Looked like a small hole where it came out. I assumed that the capacitor had bought the farm and ordered a new one. Ouch! Best price on the Internet was about $70. Is what I described typically what's found when one of these capacitors fails? |

Usually they just open or short, but leaking is possible. Jeez, $70 is a lot, last time I needed one I picked it up for something like $6 from http://www.usamfg.net/, their inventory changes constantly though so you need some luck. |

Typically they just fail. I thought they were filled with oil though, AAAACCCCKKKKK!! Invasion of the capacitor worms. Yes, normally they just open or (more likely) short.

Running capacitor
Mr. Goldwasser,
No, I did not test the capacitor. Just ASSumed it was bad. Your worm analogy was excellent. That's exactly what this "creature" looks like. Mr. DaveM, Capacitor is 25 + 7.5 microfarads at 370V. My humble abode is in Moundsville, West Virginia, US of A. New capacitor is on the way from Appliance Parts Pro's warehouse in Kentucky. My Master Card is taking a few days off to recover.

I was just going to try to help find a source for the capacitor close to your location, but not so pricey. But, since you've already ordered, I won't go to that trouble. Those multi-section caps can carry a hefty price tag, but in many cases, they can be replaced by two (significantly cheaper) single-section caps. Mounting style and space permitting, of course. -- Dave M MasonDG44 at comcast dot net (Just substitute the appropriate characters in the address) Experience: What you get when you don't get what you want |

Running capacitor_FIXED
My new capacitor arrived on the front porch late today. Pretty quick
delivery. That Kentucky place must be somewhere nearby. The AC is humming again. It was gratifying to see that the new capacitor was an Aerovox and made right here in the USA.
