Flickering is an annoying issue. Sometimes ceiling fan flickering might be a red signal of electrical issues. You should take action when you notice this problem; otherwise, your ceiling fan light can burn out quickly or damage the wiring.
There are several reasons for this problem like cheap, loose or old light bulbs are the most common of them. Besides, old switches and light fixtures may wear out for long use and cause loose contact. Low voltage is another reason for light flickering—overloaded circuits or loose wiring, which are more serious issues that cause the flicker.
But the question is how you can identify the problem. This article helps you to identify the problem and its solution. Take a look at the full article.
Number 1: Incompatible Light Bulbs.
Don’t go over wattage. You have to use a recommended light bulb. For example: if your ceiling fan brand suggests a 60W bulb, don’t use a 75W bulb. If you use fluorescent bulbs in your fixture and start flicker and if you see this issue happening with you more than once, you can go for incandescent or LED bulbs because fluorescent bulbs tend to more flicker than other types of bulbs.
If you use a dimmer switch, LED bulbs aren’t a good choice for you. Dimmer switches work best with standard light bulbs.
Number 2: Old Light Bulbs.
Every light bulb has a limited lifespan. Suppose you are using a light bulb for some years and start flickering its normal. After passing lifespan, the fluorescent and LED light bulb may start it. This is not a concerning issue, so you can replace it with a new one. But if you face this issue for a few months, there is another reason.
Number 3: Loose Light Bulbs.
For ceiling fan light fixtures, this is a common problem. Since the fan motor generates vibration, so the light bulb might lose over time. Check the light fixture and socket; if there is any loose screw, tighten them.
Number 4: Old Switches.
If a wall switch controls your ceiling fan light, check if it is old. When you close the contact for turning on the light and fan, a little firing occurred. For a long time uses the contact place might wear and tear that makes a loose contact.
If you have an old dimmer switch that might not be compatible with the new bulb. If there is any loose or old wiring behind the flip switch, it may cause flickering.
If the switch becomes hot or if you see any spark during the on/off switch, you should replace the switch. Besides, if you notice any sizzling, popping, buzzing sound, you can replace the switch.
Check your switch and light bulbs for ratings if you have a dimmer switch. This allows you to know whether or not you have a compatible set. An inappropriate set may cause flickering.
Number 5: Old Fixtures.
If you have an old ceiling fan with a light fixture, the problem is probably in the fixture. In that case, you can change your old fixture. If you are experienced in wiring, you can check or call an electrician if you cannot find a compatible light fixture for your old ceiling fan.
Number 6: Bad Current Limiter.
It might be a reason for flickering because some fan brand has a current limiter for preventing high wattage bulb. High wattage bulbs create overheating, which is not a good side for a ceiling fan light fixture. So, they use the current limiter. You can remove the limiter, but it is not recommended. Always use the exact wattage that the fan manufacturers recommend.
Number 7: Overloaded Circuits.
Sometimes you might notice your light bulb start flickering when you turn on another electric appliance. This is because of an overloaded circuit.
This results from insufficient current when the fridge starts and the ceiling fan lights flicker. Your circuit is overloaded, and there isn’t enough electricity to supply all the equipment. This also means that your lights and larger appliances are connected to the same circuit, but this is not recommended. In that case, you should call an electrician, and tell him the problem. Make sure all large electrical equipment has a separate circuit.
Number 8: Loose Wiring.
If there is a problem with your home wiring, the lights in your home may flicker, which will not occur only for the ceiling fan light. An electrician can either repair old cables or replace them.
Loose cables can cause electrical fires, so this must be fixed. The loose wiring left untreated will continue to cause flickering.
A flickering will not be a dangerous signal if it occurs for an old fixture or incompatible light bulb. But it might be dangerous if it happens for bad wiring. When you suspect that your lights flicker due to electric problems, it can become dangerous quickly. So, you should solve this issue as soon as possible.
