Harbor Breeze fan lights start to flash after 10 minutes

A site visitor recently asked the following question: They had a Harbor Breeze ceiling fan (model is unknown) that worked without any issue for a number of years in their home. After that time, when the lights are turned on, they would blink. The blinking would begin approximately within about 10 minutes after being turned on. The bulb type is LED, however it was changed to LED some time back.

Answer: The answer that another site visitor posted is the following.

Try taking of the lamps and changing it back to incandescent. It may be that the lamp controller requires a constant drain as opposed to how an LED lamp drains. Over time, lamp controllers age and they get “used to” the behavior that they have always had. A sudden change in that behaviour can cause some of the issues you’re experiencing. Although it seems strange to us, it’s perfectly normal to the lamp controller because the lamp controller is used to doing things in a certain way. You may be in a situation where the lamp controller is used to a specific current, and variations of that current is causing the lamp controller to not be able to adjust to the change.

How can I fix my ceiling fan light blinking?

Great question. Take a look at this video below. In the video, you can see the ceiling fan is continually blinking on and off. It’s quite annoying and you can’t really use the fan in this state. The gentleman in the video takes the fan apart, identifies the bad part and replaces it. This video walks you through troubleshooting this problem end to end.

What is a lamp controller?

A lamp controller is a device that allows you to control the brightness or on/off status of a light source. It can be a physical device or an electronic device that is connected to the light source.

Some lamp controllers are simple switches that allow you to turn a light on or off, while others provide more advanced features like dimming and scheduling. There are also smart lamp controllers that can be controlled through a smartphone app or integrated with a smart home system like Amazon Alexa or Google Home.

Overall, a lamp controller can be a useful tool for creating the perfect lighting environment in your home or workspace, allowing you to adjust the lighting to your specific needs and preferences.

A ceiling fan lamp controller is essentially a dimmer switch that controls the voltage delivered to the light bulb in your ceiling fan. When you turn the switch to increase the brightness of the light, the controller increases the voltage delivered to the bulb. Conversely, when you turn the switch to decrease the brightness of the light, the controller reduces the voltage delivered to the bulb.

The voltage that is delivered to the light bulb in your ceiling fan is typically controlled by a TRIAC (triode alternating current) dimmer. This type of dimmer works by chopping the incoming AC (alternating current) waveform, resulting in a lower voltage output. The chopped waveform is then smoothed out by a capacitor, resulting in a stable output voltage that is proportional to the position of the dimmer switch.

TRIAC dimmers are commonly used in household lighting applications because they are relatively inexpensive and easy to install. However, they are not suitable for use with all types of light bulbs. For example, some LED bulbs may not work properly with a TRIAC dimmer, and may flicker or produce an annoying humming sound. In such cases, it is necessary to use a specialized LED dimmer that is designed to work with these types of bulbs.

Advanced Features of a Ceiling Fan Lamp Controller

Many modern ceiling fan lamp controllers come equipped with advanced features that allow you to do more than simply adjust the brightness of the light. For example, some controllers may come with a remote control that allows you to turn the light on and off or adjust the brightness without having to physically touch the switch. Others may come with a timer function that allows you to set the light to turn on or off at a specific time.

In addition, some ceiling fan lamp controllers may also come with built-in sensors that allow them to automatically adjust the brightness of the light based on the amount of natural light in the room. This can help to save energy and reduce your electricity bill, as the light will only be as bright as it needs to be.
