www.youtube.com/watch?v=bGBWVuzOkHkThis is a video of SMC Laguna I got today. It spins less than 180 RPMs on high, so I'm thinking about getting a new capacitor. Here are the pictures of a capacitor: Does the capacitor look like it can be bad? The switch housing has been removed. I assume black is for power source, white for forward, and red for reverse. I would like to convert it back to variable speed reversible. Any ideas where I can get the switch housing and variable speed control?

Unlike the capacitors found in electronics, something like this really needs to be measured in order to find out its health.

Yeah, I had been thinking about getting a meter to measure capacitor value.

So it's black wire to variable speed control, variable speed control to L part of L+1, L+2, L+3 pull chain switch (if I can't find 3 position chain switch), 1 to white, and 3 to red, so it would be forward, off, reverse, and off. Would that be right connection?

Apparently, the red wire is for light kit, not for reverse. The red wire is sticking out on ceiling end. But seeing blacks and white wires connected together, there must have been a switch housing before. If I can't find a switch housing, would a wall solid state speed control work?

Generally when it comes to smaller capacitors found in things like computers, they often show visible signs of issues when they fail, such as they start to bulge, discolor, darken, or even separate from the board. A capacitor like this is much less likely to do those things as it beings to fail or age.

I restore TV sets from the 60s, and there are many types of capacitors in these.. Cap can look brand new and still be bad, I've also seen caps that look completely burnt out and still are good.. You can't judge by looks.. Anything that does look toasty should be replaced either way.. Only way to tell is to test it.. Ohm meter will tell you for the most part unless the cap is leaky and takes a load to fail, but most of the time an ohm meter will give you the results..
If you replace the cap and want to get crafty, you can always cut the lid of the metal can and pull the guts, sand down the terminals and solder the leads of the new cap to them, stuff the can with a box cap..

This is the last post I'm going to utilize entertaining this outrageous discussion! If we go back to my original post: Unlike the capacitors found in electronics, something like this really needs to be measured in order to find out its health. The statement is concluding the same thing both you and Adam are stating: you need to measure it in order to find out its health, looking at it isn't good enough The second part of the statement comes from my 4 years working in computer repair and 2 years managing the business: from my experience, in the vast majority of cases (not all), if a capacitor looked strange, there was something wrong with it. If it looked okay, it was probably okay. Visual check of the capacitors was the first thing I did before I went and tested each one. That's all I'm stating, nothing more and nothing less. Of course you know more about fans then I do, you've been at it a lot longer than I have. But, that also doesn't mean I was born yesterday. Don't confuse me with people like Musto, I'm not 'that kid'. I'm an adult also...

Have you ever done that to your SMC Lagunas before? Any look of capacitor is fine for me as long as they fit in lower canopy. You can't see capacitors when lower canopy is installed.

It's pretty sad when I have to go behind and delete posts by a certain individual, if this keeps up, I'm going to have to make choices I really don't want to make myself.. As for SMC Lagunas, I've never had to change a cap out of one.. This looks like an odd variation.. No blade badges, and some skinny looking switch housing, kinda like a strip down version.. Neat though.. But it's a metal can capacitor similar to the one I changed out of my Sears.. As long as you change it out with the same value, and same voltage or higher, you will be fine.. I see 200 Working Volts A.C. 13Mfd cap It actually has blade badges, the blades were just upside-down when it was installed.

Very nice.. You should try and host the picture where we are able to see them without having to download them..

And I believe the thin "switch housing" is not orginal. I'm looking for a switch housing and variable speed. Until then, would a wall solid state speed control work?

Fair enough. If I'm wrong about something, then so be it. But to throw in the additional insults, that's just not called for.
