I have a Harbor Breeze ceiling fan and light kit. When I turn on the light, it starts out bright, but then in a second it dims. It doesn't turn off, it just dims. What could be causing this to happen?

  • Is the light controlled by a dimmer, a remote of some sort, or simply by a wall switch? – ThreePhaseEel Apr 18 '15 at 2:04

    Is the lamp a compact flourescent? Some of them actually are bright when the come on and then get dimmer. I had one like that I replaced with an LED. – ArchonOSX Dec 12 '15 at 2:07

I had this exact problem. I bought two Home Decorator fans from Home Depot and installed them in separate rooms in my house. They have LED lights. I know for a fact that I wired them right because the model fan in Home Depot fan was wired the same and my remote worked perfectly with that fan. Both fans at my house had the same issue of the light not turning all the way off but dimming worked and fan speeds worked. LONG story short, I had another fan in the Master Bedroom that was turned on. When I turned the power to that fan off (wall switch toggled to off), both of the new fans worked!!! Now I need to figure out how to wire the Master bedroom fan correctly (9 wires in one box) but at least I know what the issue was!

    Can you describe how to verify the problem you had is the same as the OP and what steps need to be taken to correct it? – BMitch Jul 14 '15 at 21:16

I had the same problem with my Harbor Breeze fan. I found an remote for a fan in another room and programmed it for the fan that had the dimming issue. It seems to have fixed the problem, so I'm guessing the remote is bad.

You may want to double check that the remote is set to the correct bulb type (if it has this switch in the back). Also try pressing and holding the light button to raise or lower the brightness level.

One of the current limiting methods required by the U.S. is similar to a dimmer the current is limited by controlling an SCR and this has the effect of dimming. This may be the cause.

  • Yes, this would be the case if you have a large wattage of incandescent bulbs in there. The product labeling should state how much wattage the fan can support, it will dim if you try to add more. – Harper Feb 27 at 15:49
  • The government limit is 190 W but I have seen the active current limiters start reducing the power at under 100 W total. – Ed Beal Feb 27 at 16:15
