Why does my ceiling fan not working at all speeds? How long do ceiling fans last?

In the summer, ceiling fans are an indispensable item in the house. Sometimes continuous operation will lead to malfunctions. Ceiling fans operating at a slower or faster speed than usual will also lead to various problems. In the article about why my ceiling fan not working at all speeds at, author Toby Nwazor will also mention how long ceiling fans last.

Why does my ceiling fan not working at all speeds?

The main causes of ceiling fan not working at all speeds

There are 4 main causes of ceiling fans not spinning, 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 manual control. Make sure it has enough battery left to work.


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

How to check when the fan does not rotate

Why does my ceiling fan not working at all speeds?

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 fan runs 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 fan wiring.

In case you don’t have time to fix it yourself or don’t know how to fix it. You should contact a ceiling fan repair unit for quick and safe repair.

Why is my ceiling fan not working at each speed?

Why is my ceiling fan not working at a slow speed?

Your ceiling fan is not working at a slow speed due to the following reasons.

Defective capacitor

If the ceiling fan is old, the capacitor may have some problems due to overheating, improper wiring, etc. Bad capacitors can cause problems for all speeds. So check the capacitor regularly and maintain it.

Problem in control box

If the condenser is suitable but the fan is not operating at a slow speed, there may be a problem in the fan’s control box. You can replace the control box and fix the problem.

Engine cover problem

If you have checked the above 2 problems and still see that the ceiling fan is not working properly, the cause may be the motor cover. You can check the engine cover and replace it if there are any problems.

Why is my Ceiling Fan not working at a fast speed?

Your ceiling fan is not working at a fast speed due to the following reasons.

Less lubrication

Lubrication is required for the ceiling fan to work properly. If the oil fill in the fan is less or decreases after some days, the fan will not spin quickly. So make sure you refill the fan’s oil tank regularly.

Old or unbalanced blade

The blades of ceiling fans will collect dust particles on their surface. This can lead to loss of balance of the blades. So clean the blades regularly. The second problem could be old blades. You can repair the wings or simply replace them with a new one.

Loose screws

If the screws are loose, they can create many problems for the fan such as noise, slow speed, etc. If you realize that the screws are loose, you need to tighten them to make the fan work smoothly.

Why does the Ceiling Fan Speed ​​not change?

Zipper problems

If the fan speed is stuck overhead, the capacitor won’t be the cause. It could be a problem with the zipper. Like, the zipper might have broken or disconnected. You can fix it.

Bearing failure

If the bearings are old or damaged for some reason, the fan may get stuck at high speed. In this case, you will have to replace the bearing with a new one.

Other common errors in ceiling fans and solutions

Ceiling fans can experience many different failures, but the most common ones include the following:

Ceiling fan running slow

When you turn on the ceiling fan, you feel that it is running slowly, weakly and not as cool as usual. The cause of this situation may be due to a weak power supply or a reduced starting capacitor value. To fix it, you need to:

  • Step 1: Check the input power and motor capacitor.
  • Step 2: Use auxiliary devices to ensure sufficient power supply for the fan in case the fan runs slowly due to low power or replace a new capacitor if necessary.

Ceiling fan spins but not cool

Ceiling fan spinning but not cooling is the phenomenon when the fan has power on the fan switch and still works normally but does not generate cool wind, affecting the user’s use experience. Some causes of this problem and how to fix it:

  • Too much dirt on the fan: Using the fan for a long time without cleaning will cause dirt to stick to the motor box and the propeller, thereby affecting the fan’s rotation speed, resulting in airflow. also weakened. The simple solution is to clean and maintain your ceiling fan, add oil or replace the silver motor if it is damaged.
  • Broken capacitor: If you have tried the above signs and still do not change, your ceiling fan most likely has a damaged capacitor because this is the part that has a big impact on the fan’s rotation speed. This error was mentioned in item 1 (slow ceiling fan error), you can learn how to fix it here.
  • Damaged copper coil: After you have checked the above factors and still have no effect, it is possible that the coil has broken or due to long-term use, it is seriously degraded. This copper coil is one of the parts of the fan motor, which, when combined with other parts to operate, creates a rotating magnetic field for the fan. The way to fix this error is to take the fan to an electrical repair shop to replace the coil or buy it yourself, but this requires a highly qualified technician.

Ceiling fan not receiving control

Ceiling fans are usually controlled via a switch or remote control device. If the fan still runs normally when the switch is turned on but cannot adjust the modes by the remote control, the cause may be due to:

  • Control low battery: Fix this error by replacing the battery with a new one.
  • Control circuit failure: Check by pressing 1 button on the remote. If the red light flashes, the circuit is still normal, if the light does not flash, the control circuit is damaged and needs to be repaired or replaced.
  • Faulty fan circuitry: If you’ve checked and found no problem with the control, it’s likely that the circuitry in the fan is damaged. You need to remove the fan and use specialized equipment to check.

There is noise when operating

After a period of use, ceiling fans often make noise when operating, making users uncomfortable, especially at bedtime. Leading to this situation is usually because the bearings are damaged or out of grease, causing the plastic bulb to rub against the engine, thereby emitting a noise. You can fix it by adding grease to the fan or replacing the bearing with a new one if it fails.

How long do ceiling fans last?

How long do ceiling fans last?

How long does a ceiling fan last?

Most ceiling fans are estimated to have a maximum lifespan of 10 years, but how long your ceiling fan will last depends on how often it’s used. Homeowners who use multiple ceiling fans to stay cool during the summer should expect to replace a ceiling fan before the decade is out, or at least have their fan serviced.

Higher quality ceiling fans can last 15-20 years before needing to be replaced. The quality of a fan can certainly affect its lifespan – but so can the quality of the installation work.

To protect the integrity of your home and ensure your investments last as long as possible, be sure to only allow a trusted electrician who specializes in ceiling fan repair to do the installation or any further work on your ceiling fan.

Signs You Should Replace Your Ceiling Fan?

Your fan is wobbling

A ceiling fan is used to spin its blades in a circular motion to create air movement, but if the blades are swaying or the fan itself is in motion there is a chance that the entire unit will fall, resulting in countless dangers.

A wobbling fan is a clear sign of internal installation problems. Your blade may be out of balance, which is an easy fix, or you may have a more serious problem. Talk to a professional as soon as possible to fix that wobble.

Making a buzzing or hissing sound

If your ceiling fan is operating optimally, it should spin without making much noise. Some quiet and steady noise is characteristic of any fan, but unusual, loud, or annoying noises can be a sign of a problem.

Any kind of loud noise, humming or banging and creaking are reasons for concern. They could mean that your fan is improperly wired, poorly assembled, and it may be necessary to disassemble the fan to determine if there is a more serious wiring problem.

Ceiling fan won’t turn on/off

If your ceiling fan is no longer responding to its switch, then this is a clear sign of some kind of electrical problem. Your ceiling fan motor may be dead, or there may be a more serious internal wiring problem.

Slow down normally

Declining speeds on a ceiling fan could be a sign that your motor is failing, the wiring is loose, or that you need a new ceiling fan.

Ways to extend the life of a ceiling fan

Adjust the speed appropriately to prolong the life of the ceiling fan

Ceiling fans are a very good cooling device, but they are not the same as fans that have a much higher frequency. Because you have to cool the whole room, you need to know how to adjust flexibly when using it, otherwise the fan will quickly damage and damage the equipment inside.

Checking daily

When installing, the ceiling fan will be installed with screws very carefully. However, during use, it is easy to shake and rust if not checked regularly. It is very dangerous to use a fan with a screw system that is not tight or tight. The fan may be loud or break if this point is not noticed.

How to check as follows

After about 15 days after installation, you should check the screws for the fan again. See if the screws are loose or show signs of coming off, tighten them to secure the ceiling fan. If the screw is rusty, it should be replaced immediately to ensure the operation of the fan. After that, if you want the fan to work for a long time, you should check it once every 1 to 2 months.

In addition, if the fan shows signs of poor operation or makes strange noises, it is necessary to remove the fan to check immediately. Should see details inside the fan, check the oil to make sure the fan runs smoothly and smoothly. This helps the fan to operate more durable and have a longer life.

Clean the fan blades regularly

The fan blade is a very easy place to collect dust and jam. This makes the fan when operating will be easy to slow down and get stuck if not cleaned.

Users should clean the fan blades regularly, check it once a month, especially large ceiling fans. The thicker the dust on the surface, the easier it is to damage, the cleaning of the fan must ensure consistency for the fan to be used for a long time.

When cleaning, you should use a soft cloth, dip a little water, do not use a towel that is too wet to easily cause an electric shock. When wiping, you should use light force to avoid strong impact. Wipe all and wipe the blades evenly, then let it dry for about 15 minutes, then reinstall it for use.

Check the spare parts to prolong the life of the ceiling fan

In addition to checking the hardware, the accessories such as brackets or fan hangers. Should be cleaned and checked about twice a year. If you have time, you should check every 4 months. You can also have fan repairmen check them regularly for you if you can’t check them in person. This saves you a lot of time and effort.

When checking, you should unplug the power source first and clean it to clean the dust. Brackets should be checked for sturdiness. If it is difficult to restore, you should replace it with a new bracket to ensure the fan works properly. It is recommended to use new brackets with better resistance than the old one, so the fan will be fixed and much safer.

F.A.Q:  Why does my ceiling fan not work at all speeds? 

Why does the ceiling fan stop working after a power failure

Ceiling fans stop working for many reasons. For example, the motor exploded, the capacitor exploded, the coil burned, etc. The power failure causes a power surge at the time of restoring the power.

The cause of the power surge is the sudden jump in the current that exceeds the rated current of the ceiling fan. Because of overheating, the insulation in the fan motor burns out. It results in blowing the ceiling fan motor. It can also cause capacitor blowing.

Why can the ceiling fan only work at high speed?

If the ceiling fan can only work stably at high speed, there can be three causes and you need to check:

  • Problem in control box
  • Defective capacitor
  • Engine problems

How many capacitors does a ceiling fan need to operate at different speeds?

Usually, two capacitors in series in parallel are used in ceiling fans. The motor is called a two-value capacitor run motor or a permanent division capacitor motor.

What happens if the fan capacitor breaks down?

Even when the start coil is damaged, a defective capacitor will still allow the fan to receive electricity. It won’t be able to start the fan since there won’t be enough torque. However, you may manually start the fan by pushing it, and it will continue to run.


As can be seen from the examples above, there are a variety of reasons why a ceiling fan may not be functioning properly at all speeds. Correct troubleshooting is crucial if you want to be able to resolve the issue for the lowest possible time and financial outlay.
