It can be easy to determine a faulty fan when it makes a clicking noise while it’s running. But what happens when your ceiling fan is making noises while it’s turned off? Not only can it be annoying, but can cause you to worry about possible dangerous wiring issues.
A clicking noise from your ceiling fan in the off position can indicate a few potential problems. It can be a loose fan blade shifting, a motor that has gone out, or a remote box sensor attempting to receive a signal.

Common Causes for Clicking Ceiling Fans
By listening to the type and frequency of the noise, you can narrow down the potential causes of the clicking.
Loose Fan Blades
Even though this is commonly thought of as a problem when the fan is turned on, loose fan blades can still make a clicking noise even when the fan is in the off position.
Somebody walking on the floor can make just enough vibration to rattle the loose blade. Even a strong gust of air from a window or a door that swings open can shift it ever so slightly.
If the ceiling fan makes random clicking noises, grab a screwdriver and tighten each fan blade to the fixture. Also be sure that the wiring cap is firmly attached to the ceiling, as this could be the cause as well.
Malfunctioning Remote Receiver
Some ceiling fans can be operated by a remote control and have a remote receiver box inside their ceiling cap.
If this type of fan is making a clicking noise while it is off, it could be your receiver box attempting to reset itself or falsely receiving a signal. Contact the manufacturer of your remote fan and request for troubleshooting tips.
A Fan on a Dimmer Switch
Dimmer switches are usually used for lighting as their nature allows the user to control the voltage of the lights. Because of this variable voltage, it is not recommended to hook them up to a fan.
A loud, repetitive clicking noise from a fan on a dimmer switch indicates the fan motor is not receiving the correct voltage. This can cause an incorrect amount of power to go to the motor and prevent it from working at all or even worse, overheat it and cause a fire.
Blown Light Bulb
If you heard one loud clicking noise shortly after you turned your fan off, chances are one of the light bulbs has blown. Turn your lights and fan back on to ensure they are all working correctly.
Light Bulbs Cooling Off
Some light bulbs can generate a fair amount of heat and get hot to the touch, especially if on for a prolonged period of time. The heat generated can cause some components of the bulbs to expand – a fairly normal and innocuous thing.
If you notice a clicking noise several minutes after you have turned your fan off, it may be the light bulb components cooling down and “shrinking” back after having expanded from the heat.
Though this is usually harmless, it is an indicator that you will probably need to replace your light bulbs soon.
Malfunctioning Fan Motor
If your fan appears to be off but the switch controlling it is on and you hear a repetitive clicking or buzzing noise coming from the unit, your fan motor could be faulty.
You may need to check that it’s lubricated well so all of its parts work smoothly. If there are no apparent outward problems, such as burnt wiring, contact an electrician to replace your fan motor.
If the fan and the light are on one switch, it’s not uncommon to turn off just the fan using the chains while leaving the lights on.
If the blades are not rotating but the lights are on and accompanied by a repetitive clicking noise, this could indicate a wiring issue inside the hub.
Unfortunately, unless you are a seasoned electrician, messing around with wiring can be dangerous, so it is best to call a professional.
Is a Clicking Ceiling Fan Dangerous?
The answer to this question is difficult because the cause of the clicking will determine its danger level. While a loose blade could potentially fall and hit somebody, this is unlikely unless it was installed with a fair amount of neglect.
On the other hand, a wiring issue can cause a spark and ignite a fire. This can be particularly dangerous in ceiling fans because their wiring is enclosed in the ceiling cap, thus obscuring the fire from view for several minutes.
If you notice any strange smells accompanying the clicking noise (commonly described as the smell of burnt popcorn), contact a professional electrician right away.
Although any strange noises coming from your appliances can create concern, rest assured that a clicking noise from your ceiling fan usually has an innocuous cause and can be fixed quite easily.
