How a ceiling fan works

A ceiling fan makes the room more comfortable in the hottest summer temperatures. Because there's a breeze blowing into a room, you can turn up the room thermostat by 5-7 degrees, dramatically lowering your air conditioning bills.

And in winter, a ceiling fan can be inverted to circulate warm air upwards. This allows hot air that would otherwise collect in the ceiling to be pushed back into the room for added comfort.

Parts of a ceiling fan

A ceiling fan consists of a few basic parts, namely an electric motor with a housing, blades and the "iron" that holds most types of blades in place, and a rod or other mounting device.

In addition, many fans are designed to accommodate decorative "inserts" under the blades that hold glass or crystal lamps and shades. Some have a wall-mounted controller or handheld remote.

For a more detailed discussion of job parts, seeHow a ceiling fan works.

About ceiling fan manufacturers

Most fans are sold by a few companies including Hunter, Casablanca and Emerson. Many others import or distribute ventilators under a variety of labels.

Most of the fan parts and spares come from some sources in China. Because of this, fans offered by competing companies are often similar. Many US companies import, package and distribute these components. The best indicator of quality is a solid guarantee.

Okay, let's get started on fixing your ceiling fan!

Ceiling fan does not work at all

Be sure to turn off the fan's circuit breaker before disassembling the fan or its switch!

These are instructions on how to troubleshoot a completely dead fan. In other words, he doesn't hum or try to flip to no avail. You press the button and nothing happens. Zero. zero.

See the bottom of the page for solutions to other issues.

If a ceiling fan isn't working, the first thing to do is check to see that it's receiving power from its switch and your home's circuit breaker or fuse box.

Firstcheck the breakeror fuse, then the switch. Locate the electrical panel that powers the ceiling fan circuit. This circuit is usually the same one that powers overhead lights in the same room or area. Look for a tripped circuit breaker. If you find one, turn it completely off and then back on again - this is how you reset a breaker. Then try the ceiling fan again.

If that doesn't work, keep testing to see if the switch that controls the fan is broken or not.

The switch is essentially a gate that opens and closes to interrupt or complete the circuit of the black ("hot") wires. So the idea is to complete the circuit without the switch to see if it works. You do this by removing the switch, twisting the bare ends of the black wires together, and screwing on a wire nut to secure them. If the fan works when doing this, then the problem is with the switch, which you simply replace.

See how:

1turn off the powerto the fan circuit in the breaker panel.

2 Remove the switch cover plateand unscrew the screws that secure the switch to the control box.

3use avoltage testerto check the screw terminalson the side of the switch. Make sure they are not "hot" (electrically charged). When you're sure, carefully pull the switch and cables out of the box.

(See our article for more information on how to safely test a loaded circuitProblems with electrical wiring.)

4unscrew the wiresof the switch terminals. If the wires go into the holes on the back of the switch, push a very small, flat screwdriver into the square grooves next to the wire holes to loosen them.

The ground wire must be green or bare - it has no electrical charge. On the other hand, one or two black wires connected to the switch carry a load when the power is on. (In some cases, a white wire connected to the switch terminal is wrapped in black electrical tape to indicate that it is a replacement for a black wire.)

5Turn the circuit back on.If the fan turns on, the switch is faulty. In that case, simply purchase and install a replacement fan switch. You might want to explore some of the optional switch types available, from timers to Wi-Fi controlled switches.

If the fan still does not work, the problem is with the fan wiring or bracket.

6Turn off the power to the circuit again.Reconnect existing switch and reinstall cover plate.

The next step is to check the fan support or call an electrician.

Ceiling fan blades are not turning properly

If the fan can be turned on but the blades don't spin, only run at one speed, or change speeds unexpectedly, most of the time, the fan capacitor is broken or faulty. To see "How to Replace a Ceiling Fan Condenser," sob.

If the fan light works and/or you hear a fan noise when you click the remote or button, you know there is power and the button is working. Toggle the "Forward-Reverse" switch (shown in the video below) several times, then set it to the "Forward" position and try again.

If that doesn't fix the problem, make sure the DIP switches on the fan's receiver and remote control are set to the same frequency (you may need to look up your fan's manual online to do this).

If the blades don't move when you push them by hand and it's a new fan, the packing material may be blocking it. If it's an old fan that worked previously, a screw or piece may have come loose and become stuck.

How to Replace a Ceiling Fan Condenser

Most fans have a "starter capacitor" that gives them the boost they need to start spinning. If this capacitor burns out, it must be replaced or the blades will not rotate or rotate incorrectly.

Changing the ceiling fan starter capacitor is easier than it looks, as shown in the video below. When you go to a hardware store to buy a replacement, pick up the old capacitor (or a picture of it). It is very important that you get a suitable replacement.Be sure to disconnect the circuit before disassembling the fan!

Finally, the motor may have burnt out, in which case it's probably best to buy a new fan. see ourceiling fan buying guide.

How to fix a fan hum

If your ceiling fan is humming while running, changing the controls may solve the problem. This is a relatively easy fix, but it may not work if your fan has a very cheap motor - the motor could explode.

Make sure you buy a controller that is compatible with your fan and has an anti-hum feature. The current rating should be equal to or greater than your ventilator's requirements. Multiple fans or fans with lights may require special controls.

1turn off the powerfor the fancircuit breaker.

2Check fan switchto make sure it's turned off.

3Remove front panel and switch.Use a voltage tester (see above) to ensure the wires connected to the fan switch are not "hot".

4disconnect the wiresof the switch.

5Flatten the ends of the wiresin the electrical box and twist them with the wires from the new anti-hum fan control.

6add wire nuts,Screw the controller to the control box, reconnect the front panel, then reapply power.

How to fix an unstable fan

While slight oscillation is typical for ceiling fans, excessive oscillation can be dangerous. Start by finding the source of the jitter. In many cases, wobble occurs when a fan is hung from a normal overhead control box instead of a fan-rated control box. A fan exerts much more force on the electrical box than a light bulb due to its weight and constant movement. If a fan comes loose, it could fall.

1Unscrew and lower the stand bodyon the ceiling. Check that there is a label on the electrical box identifying it as a fan box. Also check how it is connected. U-bolts or lag screws should connect the metal box to a solid wood support or block in the attic.

2Check fan support.If the fan is stuck in the wrong type of housing or is clearly poorly supported, see our article.How to install a ceiling fan.

If the work involved seems beyond your abilities, call aFan repair professionalor an electrician.

Note: If you are unable to determine the type of support underneath, you may need to climb into the attic to check. Before doing so, try steps 4 through 7 to see if these simpler steps resolve the issue.

3Stir the support bracket.If it's not tight, tighten it.

4Check the left bar.If your fan is hanging from an overhead bar as most do, make sure the ball joint at the top of the overhead bar is properly connected to the fan bracket.

5Check all bolts and screws and tighten if necessary.

6Measure to see if the blade tips are evenly spaced.from the ceiling. Otherwise, one or more blades may be bent or warped. Report this to the manufacturer. Most fan manufacturers offer replacement blades.

How to replace a fan flywheel

A flywheel is a rubber washer that holds the ceiling fan motor shaft to the blades. The rubber helps minimize vibration in the blades, but over time the material can crack and break.

If the fan stops spinning but the motor continues to hum, you likely have a damaged or cracked flywheel. It's better to replace the fan flywheel - or the entire fan - than to try to repair it yourself.

Replacement flywheels are relatively inexpensive and available for most ceiling fan models. Determine what make and model you have. If this is not immediately apparent, remove the broken flywheel and carefully measure it. Be sure to note the inside and outside diameters, as well as the location and distance between the bracket and the screw holes.

Then find a replacement part at a licensed dealer or parts distributor - or search for the part online.

To remove the failed flywheel, you need to disassemble the fan assembly.

It is helpful to take a photo of the fan when disassembling it to help with reassembly.

Be sure to turn off the power at the circuit breaker before working on the fan..

1Remove the fan bladesand open the fan switch housing.

2Disconnect all switches and controls,note how and where they were connected.

3Disconnect all wiresconnected to the engine and make sure you know where to reconnect them once the new flywheel is in place. Then, remove the entire switch housing using a screwdriver, wrench, or pliers, depending on the model.

4remove the faulty flywheel,Note the exact placement on the shaft. It may be a good idea to mark the location with a permanent marker after removing the steering wheel.

5Slide the new steering wheel into placeand make sure that all the wires go through the correct holes as in the previous assembly. Tighten all screws and replace any other parts that may have been removed during the process.

6Reconnect any switches or controlsand replace housing. Replace the blades on the fan and test.
