i'm working on fixing a big industrail stand type fan made by fridgid i guess form the 1970-1980s. it was running then it started making a bunch of noice and slowed down heated up some. oiled the berings tryed it it hummed but wouldn't spin up. we taped the blade with a screw driver and it took but didn't run very fast. In the switch, power conection enclose i removed there was a big metal oval shaped capacitor. I think this is a run capacitor i looked up the values and got run capacitor. here are the numbers on it. york 36 03 78 4 mfd 370VAC 1010. then it says contains combustable fluids use caution in disposal. this makes me think it is an oil capacitor. it does have a red polarity mark. from the symptoms i figured it was this and pulled it out. when i pulled it out i noticed the end with the terminals is kind of bulged out. it has a gob of solder on this side looks like a presure relief but it is iether ok of didn;t get to the pint of breaking. is this an oil capacitor? i have seen a few online that look like it but not sure what this is to compare it. i would think if ratings are the same anythin would work as long as it fits the enclosure cover. is that corect? does this sound like a failed one? i have no way of rely testing it with what i have. other than charge to 12v and see if it holds. but that doesn't tell if it is the proper value.
