The light works on my ceiling fan, but the fan does not. My brief research suggested that I check the capacitor. I disassembled the unit, and I find two things in there that look similar--one being a bit smaller than the other. Neither one exhibits the bubbling/melting that suggests that it's been blown.

I've attached a picture that shows both. Can anyone help me identify what they are? (The larger unit has four wires--grey, pink, and 2 yellows--and the smaller has three wires--red and 2 whites.)

Also, if they both look OK, does it pay to replace them to see if that solves the problem? Or is it time for a new fan? (We moved into this house in June, and I don't think we've ever turned the fan on. The first time we tried, the chain on the pull switch broke, and I just got around to replacing that pull switch. That's when I found that the fan doesn't work.)

Many thanks!

  • "4L" would imply 4 henrys of inductance, either as an inductor or choke. The other is a dual capacitor with integrated bleeder resistors. Inductors don't typically wear out, they are just coils of wire. large caps like that can dry out, so that's where the smart money is. – dandavis Feb 21 '19 at 16:01

They are capacitors made by Seika to be compact to fit into enclosed spaces. Testing caps is very easy enter image description here you have to be careful when dealing with caps because they are essentially quick charge/discharge batteries and are capable of giving you a zap with the power off. The the resistor on the diagram of the cap indicates that it discharges itself when the power is off, but it's still best to be cautious. If you test and it fails they are available for replacement. enter image description here This is an example of one on Amazon, however this is a triple cap. And to clarify the second one is also a capacitor enter image description here it's a 4 micro farad run capacitor.
