I am trying to replace my capactitor in my ceiling fan, because the blades do not spin but I do hear a humming sound. When I opened it up. I have 2 capacitors

The first capacitor is smaller and has 3 wires and is rated 4uf 250V Red White White

The second capacitor has 3 wires and is rated 5uf 470 1/2W and 6uf 470 1/2W Gray Purple Brown

My question is I CANNOT find ANY matching capacitors online! Does anyone know what other kind of capacitor I can use?

EDIT: To clarify lets say I buy these two capacitors, how exactly would I wire this? I couldn't find matching capacitors online

  • I assume these are for the speed control -see my answer.. – Ken Apr 19 '17 at 20:02

Yes they are speed control capacitors.

For clarification as another poster pointed out - one is for speed settings (4.5uf with resistors - aka RC network) the other 5uf is a run or start capacitor. The link below is a package with 3 capacitors built in - note it does not have the RC network for the speed control but has your 5uf - 250Volt you can use for the start/run capacitor, it might work to replace both of your units - there are others that have these 3 capacitors with 5 wires as well making it easier to install.

  • Well, one of them is :-) – Carl Witthoft Apr 19 '17 at 20:03
  • @CarlWitthoft The 5uf is probably a start capacitor - 5uf sounds like that - you should find it in the same place. The link had a triple capacitor - probably usable in the ops situation.either way he needs to use the right terminology to search it - Ceiling Fan Start Run Speed Capacitor or a combo of those terms.. – Ken Apr 19 '17 at 20:06
  • Ok so if i would get this particular capacitor- I would match up the wire colors with purple to purple gray to gray brown to brown and red to red. But that leaves me with 2 white wires and a gray wire left over? I'm a little confused with the wiring? Do I also need to find a RC network capacitor? – kozmo Apr 20 '17 at 16:28
  • @kozmo I added a diagram - although you have 6 wires - you really only have 5 connections. Two of your old wires actually connect in the same place. See the added diagram for more clarity - I hope that helps you. This should work - but the resistors are a timing / filtering - in other words they filter electrical noise. I have used this setup in mine with no problems - you might even find these capacitors at a Home Depot (about 3 months ago I picked mine up there). – Ken Apr 21 '17 at 17:52
  • @Ken: Thank you so much!!!! I appreciate all your help – kozmo Apr 21 '17 at 17:57

First of all, the "470K" represents the resistors. The caps are 4 and (6 parallel to 5) microFarad respectively.

The second package contains a filter consisting of 2 caps and 2 resistors.

In any case, start by tracking down "SK" company, or check out the link in the other answer.
