We have put together this guide to help when errors that prevent ceiling fan light wont turn on. Toby Nwazor’s article at will also cover ways to troubleshoot of common problems of ceiling fan light and make them easier to handle.

Errors that prevent ceiling fan light wont turn on

There are 4 causes of ceiling fan damage including:

Power supply

It is possible that the power cord is loose or short-circuited. If the ceiling fan is not spinning, the first thing you should do is check the wiring. Check to see if the wire is shorted or loose.


Engines can fail due to design flaws or technical failures. You should contact the supplier to claim the warranty.

Control box

Many people think that the ceiling fan is not spinning because the fan is broken. But few people expect it to be the controller’s fault. If your ceiling fan uses a handheld remote. Make sure it has enough battery left to work. Or in the case of a controller problem, the controller’s signal reception system is broken. The worst case scenario is that you may have to purchase the entire fan control system new.


The cause may be due to the wrong way of installing the fan or a technical error occurred during the installation process.

Burned bulb

This will sometimes cause the internal underground circuit of the ceiling light to fail. The underground fire will not be able to run cool when the ball is burned.

How to check the failure of ceiling fans and lights

Errors that prevent ceiling fan light wont turn on.

To check the ceiling fan when the ceiling fan is not spinning, follow these steps:

Step 1

Please disconnect the power before opening the control panel. Use an electrical tester to check for safety.

Step 2

Remove the wire directly connected to the switch or switch of the ceiling fan. Then check and connect the ceiling fan directly to the power supply

Step 3

If the ceiling fan is running normally when the power is turned on, the cause of the failure is the switch or switch of the fan. You need to replace it. If the fan is still not spinning, the problem may be with the wiring or the fan motor itself. You can double check the wiring of the ceiling fan light.

How to remove and install the ceiling fan light for repair

Steps to remove the ceiling fan light

To remove a complete ceiling fan, you must prepare all the necessary tools. Here are the detailed step-by-step instructions:

Steps to install a ceiling fan light

The process of installing a ceiling fan also needs to follow a certain sequence. This helps you to install the machine in the correct order to reduce the chance of errors. The steps to install a ceiling fan include:

Step 1

First when installing, you have to drill the ceiling and install the fan bracket on the ceiling. Then you thread the fan’s wire into the mounting bracket. Do not connect the fan’s power supply to the main power source. Note: Do not turn on the power supply during installation.

Step 2

Thread the ceiling fan’s cable into the hanging knob, place the fan in the correct direction that the user manual instructs. After installing the cable, install the ceiling fan circuit in the section under the latch.

Step 3

Hang the fan and reconnect the power cord, this is a very important and dangerous step. If you do not check carefully during the installation, you forget to lock the main power supply. It is very dangerous to reconnect a wire that has been hung from the frame to the mains power of the home. Directly affect your life if you get an electric shock. Customers should have a little knowledge of electricity to make the installation and electrical connection go smoothly and safely.

Step 4

Reinstall the propellers firmly as shown. Secure all with bolts and rubber mattress. Double check and try again to see if the propeller part is secure.

Step 5

Double check that everything from the screws to the propeller is secure. Turn on the power, turn on the fan and run a test to see if everything is perfect.

Ways to troubleshoot of ceiling fan light

Ceiling fan light slow rotation

The ceiling fan light is too dusty

The phenomenon of too much dust and dirt on the ceiling fan is also one of the main causes of its slow rotation. You will notice that after a period of continuous use, this product is very susceptible to dust, especially the propeller and engine operation. Because of the feature of installing ceiling fans on high ceilings, we do not pay attention and face many difficulties in cleaning. Gradually the propeller becomes heavy because it collects too much dust, so it will cause the fan to rotate slowly.

Engine is running dry

How to recognize the dry oil condition in the ceiling fan with the light. When you notice that the ceiling fan is spinning slowly and showing signs of making a loud noise, it is likely that the condenser is dry. At that time, the progress of friction between the capacitor and the large propeller creates a very annoying hum during use.

The condenser part of the ceiling fan light with the light is broken

If you have cleaned the ceiling fan and fully lubricated it, but the ceiling fan is still spinning slowly, it may be because the fan condenser is badly damaged.

The copper coil of the ceiling fan with the lamp is damaged

Copper coil parts in long-term use, this part is also very easily damaged.

Ceiling fan light does not run cool

This is probably a question that many consumers are interested in – Ceiling fan is still not cool even when running? This error usually originates from the following reasons:

High ceiling

When installing a ceiling fan with a light, the ceiling of the room is too high, so cool air cannot spread throughout the space. This product line needs to be designed to be compact and maximize cooling efficiency as well as aesthetic value.

Turn on the swing reverse mode

Currently, most traditional ceiling fans are designed to rotate in a counterclockwise direction to create a cool breeze radiating from above to push down to the floor. With the mechanism of action to absorb moisture from the floor and push the hot air down from the ceiling. This is also considered the cause of the fan spinning without cooling.

The cool breeze is blocked by the plaster layer

Ceiling fans with lights installed on plaster or wooden ceilings will block the wind. This is the cause of the ceiling fan running without cooling, not promoting its inherent performance.

Ceiling fan light makes noise

In the process of long-term use and operation at full capacity, there are certainly many households experiencing the situation of ceiling fans with lights rattling, buzzing, oozing or running not smoothly. The cause comes from the following problems:

  • The screw that attaches the shaft to the propeller is loose.
  • The layer of dirt and dust clings to more and more on the surface of the wing.
  • Ceiling fan has dried oil in the internal bearings due to long time not using.

Maintenance instructions for ceiling fan light

Check the screw part

You should check this part first to avoid the ceiling fan being dropped or damaged after a period of operation. Loose screws can make noise when the fan is running, causing discomfort.

It is even dangerous for the user if the motor and fan blades fall out of the fan housing while in use. So before servicing, please check the screws, if loose, re-tighten them. Also check the fan cover for looseness.

Clean the propeller part

The impeller is the second part that needs cleaning. Because the hanging fan and propeller are quite large, to save time and effort, you should use a vacuum cleaner. Using the machine will help the dirt to be sucked more thoroughly, then remove it for cleaning. For metal fan blades, it is recommended to use warm water to clean. In winter, you should add a little vinegar water to prevent the fan from getting moldy.

Many cases even arbitrarily remove the fan blades to make the fan cooler. This should absolutely be avoided, as it will lead to engine unbalance, and that is the cause of the above phenomenon. If you are not careful, you will have to spend money to buy a new ceiling fan light.

Check the engine part

This is an easy-to-wear part of the fan when in use. You should add 2 to 4 drops of machine oil to the fan bearing to keep the fan durable. This also helps the ceiling fan light to operate stably, avoiding oil from sticking to tissue wires and silk when in use.

 Oil the ceiling fan light

When detecting the cause of the slow rotation of the ceiling fan due to dry oil, we fix it by cleaning the dust on the fan blades. Then you pour some oil on the bearing. If the silver shaft is damaged or worn out too much, it should be replaced to ensure safety and increase the durability of the ceiling fan.

Replace the new capacitor

Damaged capacitors can lead to capacitor explosion, condensate, which is dangerous to users. Broken capacitors are also very difficult for users to replace and repair themselves at home. Therefore, consumers should go to the nearest shop to replace a new capacitor with the same capacitance and voltage as the old one.

Replace copper coil

Similar to capacitors, replacing copper coils requires specialized knowledge and care. Therefore, to repair a damaged coil, it is best to replace a new copper coil at an electrical repair shop.

Clean the ceiling fan regularly

You should carry out cleaning of fan parts about every 3 months. This is to prevent dirt from sticking to the propeller, motor, and control box. At the same time, check the fan blades regularly to see if the light fan blades are balanced to avoid shaking when operating.

Change the light bulb

You should keep a record of the number of days you have used the bulb to change the bulb on time. By letting the light bulb burn out in the ceiling fan, it can lead to a fire.

Notes for users when fixing ceiling fan light errors

  • When inspecting and repairing ceiling fans, turn off electrical switches and power supplies such as circuit breakers and fuses. Let the fan turn off completely before touching it, to avoid the fan stopping suddenly, violently shaking.
  • Before repairing the slow spinning ceiling fan light, you need to determine the cause and then proceed to repair the fan.
  • After fixing the errors, you should pay attention to reinstall the correct technique, do not install too loosely, it will endanger yourself when turning on the fan.

F.A.Q: Ceiling fan light wont turn on 

How to check the power in the house?

It is necessary to carefully check the power source at home to see if it is suitable for the use of the ceiling fan. You should install a separate electrical panel for the ceiling fan and regularly check the status of the installation and the electrical panel to make sure the fan is not damaged when in use.

How to replace when there is 1 light on the ceiling fan broken?

For the lights on a beam ceiling fan, which is a combination of many bulbs, when 1 lamp is damaged, it needs to be repaired immediately. Because if not very quickly then the remaining balls will be completely damaged.

Does running a lot in one direction cause the ceiling fan light to break?

This does not affect the technique of the ceiling fan light. Of course, you should adjust the fan direction accordingly. In the summer, you should let the fan rotate clockwise, cool air will come down from the top and spread throughout the room to cool the room, airy and comfortable for users. In winter, let the ceiling fan light rotate in an anti-clockwise direction, this rotation helps the room to be airy without creating cold air for the user.

What bad habit makes the ceiling fan light quickly fail?

Continuously opening the large fan will cause the ceiling fan to operate at full capacity. This will cause the ceiling fan’s power supply to be damaged quickly, the lamp being hot for a long time will easily explode.

You can increase the amount of wind for a short period of time and then adjust it to suit the weather. Moreover, opening the fan to straighten the body for a long time will affect health.


Surely the above information will help you to handle the ceiling fan light wont turn on situation. Don’t forget to remember the ceiling fan condition so you can fix it in time.
