why does my ceiling fan keep blowing light bulbs

The ceiling fan light bulb can frequently blow because of some reason. If you can identify why your ceiling fan keeps blowing light bulbs, you can solve this issue quickly.

You can easily detect some causes of light bulb failure, and others can be more difficult to find. Vibration is the most common cause for blowing ceiling fan light bulbs. Ambient temperature and voltage vibration (slight) are another two issues.

The good thing is, you don’t need any special tools, and your common sense can detect the issue most of the time. In this article, we will mention all possible causes and their solution.

Number 1: Vibrations.

You can think your ceiling fan doesn’t make any vibration. Every ceiling fan motor makes vibration. Actually, to damage a light, a slight vibration is enough. Because there is a delicate tungsten filament wire is used to produce light.

Now the question is, all the light fan bulbs burn out quickly or before their expected lifespan. No, if you can reduce unexpected vibration, the chance of blowing will be decreased.

Some extra vibration might produce from loose fan blades. Besides, from a bad bearing, a little noise and vibration can cause. So you need to check the fan blades and bearing.

Sometimes, you can’t notice any vibration with the naked eye. So, set up a step ladder to reach the fan and check all visible screws. If you find any loose screws, tighten them.

Another cause of vibration is uneven dirt. You need to maintain your ceiling fan timely. Every month, try to clean your fan blades. If you don’t clean your fan for a long time, a thick dirt layer might have on the fan blades. It can reduce fan speed and deliver vibration.

If you have proper cleaning equipment, ceiling fan cleaning will be fun for you. Use a pillowcase to clean your fan blades. Also, you will find a ceiling fan cleaner brush that makes your job easier. Then it will not be difficult to give 5 minutes in a month for cleaning your ceiling fan.

Another easy solution is to buy a fan-rated light bulb. These bulbs are specially made for ceiling fans that can absorb motor vibration and will not burn quickly.

Number 2: Excessive Wattage.

Most of the ceiling fan brands mention the maximum wattage for their light fixture. If they recommend 60 wattages, don’t want to go for 75 wattages. It will provide you with some extra light but will because of early burnout. So, you should follow the recommended wattage rating.

This rating refers to the ability of heat transfer produced by the bulb. The use of the big-sized bulb causes too much heat, which decreases the bulb’s life cycle and the lamp’s socket.

If you need more light, add more light separately but don’t cross the wattage limits of the ceiling fan light fixture.

Number 3: Bad Electrical Connections.

Sometimes a new light bulb can start flicking. In that case, you need to check the light fixture connection. Most probably, it is the cause of bad connections.

Turn off the circuit breaker and make sure there is no presence of electricity using a current tester or a non-contact voltage tester. Now remove the light bulb and open the light fixture kit to check if there is any loose connection.

A loose connection can occur firing. It can damage your light bulb. So, check all the screws are tight enough and secured. If you will find any issue with the socket, replace the socket. A bad socket might be overheating.

Number 4: High Line Voltage.

The high-line voltage is not the reason if it happens with only a fanlight. If all your light fittings have the problem, suspect a potential high voltage problem.

Light bulbs are designed to operate for specific voltage, like 120 or 220 volts. For overvoltage, light bulbs are affected more than the other electrical home equipment.

If you think your ceiling fan light burnout for over-voltage, check the line voltage using a digital multi-meter; if you see the voltage is over 110 or 210, contact the power supply company.

Final verdict:

A good light bulb can use 1000-2000 hours, and a LED can run for 25,000 to 50,000 hours. Typically, a good LED bulb should last 3 to 5 years and a regular bulb for one year. Light bulb burning is a common issue, but it is a matter of concern when it blows frequently.
