We have a modern Hampton Bay ceiling fan and light fixture. Recently, when I turned the lights on I heard a bulb pop and the whole thing went dead, lights and all.

I believe the capacitor in the photo is the culprit. I know I can probably replace it, but is there a chance I could bypass it and wirenut the red and white wire together? I checked the breakers, they weren't tripped.

  • What are these anyway, y'all? Start capacitors? If so, and IF you can just nut them, the fan prob won't start anymore. – Mazura Jul 30 '17 at 18:59
  • Is there a dimmer involved? – Tyson Jul 30 '17 at 20:46
  • @Tyson not a traditional dimmer on the switch. It does have a wireless battery remote, which when you push the light on/off button, the lights romantically get brighter taking about one second to go from off to full brightness. There's no dimmer the user can control, but something tells me there's a dimmer built-in to create that effect. – dankeshawn Jul 30 '17 at 20:52
  • That's the part that blew. – Tyson Jul 30 '17 at 20:55
  • @Tyson which part, the capacitor in the photo? – dankeshawn Jul 30 '17 at 21:44

Usually a capacitor in a single phase motor circuit is to shift the phase of the start winding so the motor will start.

Otherwise a single phase motor will just sit there and hum since it will be locked up.

Here is a diagram of a ceiling fan circuit.

If you bypass or short circuit the capacitor I believe the fan motor will no longer start.

Better to replace it if it is broke.

If you disconnect it from the circuit and test it with an ohm meter a good capacitor will show zero at first and climb to infinity. Then swap your leads and it should do the same again. If it shows open or shorted it is broke.

Good luck and stay safe!
