How To Tell If Ceiling Fan Capacitors Are Bad

A slow-moving ceiling fan is majorly annoying. The problem often occurs due to bad conditions of the capacitors. A fan’s capacitor works as a backup when it needs more energy during high demand. However, diagnosing the ceiling fan’s bad capacitor is relatively easy.

One of the shortest ways of finding out the bad capacitor of the ceiling fan is realizing whether its blades are spinning properly or not. Hence, the fan’s capacitor usually comes with a black box underneath a switch housing. Sometimes its case seems to be burnt or damaged very badly. Yet this isn’t the exact way. 

There are some other ways to do this. So, read this article where I discuss them in short with detailed information. 

5 Signs Or Symptoms That Tell The Ceiling Fan Capacitor Is Bad

 A lousy capacitor ceiling fan can be diagnosed in many ways. One of the common ways is its slow-spinning blades, disconnected battery, etc. Below are some common symptoms of a bad capacitor, try to find them gradually. 

1. Burning Capacitor Case

One common problem one may notice is the capacitor case burning for overheating. The capacitor gets hot or warm for the spark light heating. If one sees this, it will be a particular issue that the capacitor gets damaged. 

2. The Fan Stop To Spin 

The lousy capacitor does not spin properly even if one turns on the regulator at full speed. That means it will hang, or one must push the blades by hand to activate the fan. So, the second issue one may watch out for is that the lousy capacitor fan is either worn out or didn’t move properly. 

3. The Fan Speed Gets Slow 

one fan may freeze or don’t move while turning on the switch. Sometimes, the speed of the fan is going to be very slow. Producing slow speed over time is a common symptom of the lousy ceiling fan capacitor. This also suggests that the capacitor leads to a miserable condition that needs fixing soon. 

4. Capacitor Test’s Bad Or Poor 

If one doesn’t identify the capacitor condition, take a read from a multimeter. This is the quickest way to observe the specific situation of one fan’s capacitor. Try to check; if it shows one unusual number or wrong information, one capacitor is the worst. 

5. The Fan Makes Awkward Sounds After Turning On

The lousy capacitor usually gets stuck in the middle of the spinning. It happens since the capacitor fails to get enough voltage even though the external transmitter provides the same power capacity (220V) at one home. For this reason, the fan makes a weird sound whenever one turns on the switch. 

Don’t think it’s normal; this could also be a primary stage of the worn-out or damaged capacitor. 

2 Ways To Test A Ceiling Fan Capacitor For Checking The Condition

Before troubleshooting the lousy capacitor, it is obvious to ensure they’re terrible. There are two options to be confirmed about this affair. One of them is using a multimeter. Another one will be done without any collaboration of a multimeter kit.

So, get an idea about these processes to troubleshoot the matter. Because without a multimeter kit, one can still check it out swiftly. 

Way-1: With The Help Of A Multimeter Kit 

Separate the capacitor first before installing or connecting them with any multimeter kit. Multimeter kit usually comes with different wires with metering capabilities. Usually, this machine can read the exact condition. So, do follow the below steps to check the capacitor conditions.

Step-1: Turn Off The Fan & Separate It From The Connection 

First, turn off the fan. Separate it from the primary connection. Then discharge the capacitor from the fan. Use the manufacturing menu list to find the exact location of the capacitor.

Now, find the location to separate the capacitor from the other parts. Be aware while discharging; separating the other wire from the fans may lead to splitting it. 

Step-2: Connect The Capacitor With An AVO multimeter 

After discharging the capacitor, use an AVO multimeter to read the tool’s voltage. Set the multimeter power voltage from around 10,000 ohms to 1 million. It is an ideal reading of the multimeter; hence, the capacitor is meant to display ridiculously high power voltages.

However, connect the capacitor with the two different color wires of the multimeter. Test the power voltage by holding them for a minute. Join the red wire to the positive and black to the negative terminals. 

Step-3: Check Out The Resorts

Now it’s time to check the results or outputs. A shorter or damaged capacitor will have low readings, whereas an open capacitor doesn’t show any number. If the multimeter display shows a high reading or if it continues to inch towards infinity, it is a good sign that the capacitor condition is OK.  

Way-2: Check Using Voltmeter & Terminator 

Check the capacitor values by measuring its voltage and attaching it to a voltmeter. Another way is shorting the capacitor terminals. Both of these processes require similar steps, which have been proclaimed below. So read them shortly to get a quick idea of it. 

Step-1: Disconnect The Capacitor From The Board & Read The Voltage Rating

To do the task using a voltmeter or capacitor terminal, first then discharge it from the board. Check the voltage power ratings of the capacitor. It is most probably situated on the body part. With this, try to find how much voltage power it may produce at once. 

Step-2: Charge The Capacitor By The Voltmeter 

Now let the capacitor charge for a few seconds. Don’t forget to connect the positive one to the voltage positive power source and the negative one to the negative power source. After connecting them, wait a moment. If using capacitor terminals, try to connect them similarly. Leave it for at least 3-4 seconds to charge itself properly.

Before moving on to the next step, note that a 9 volts machine only can connect to a 25V capacitor. Again, grab a 400V voltmeter to read or inquire about the 600V capacitor. 

Step-3: Set The Voltmeter To Read The Consistency 

Once completed, charge the capacitor properly and connect it with the voltmeter to read the exact power voltage. Follow the same procedure while using the terminator.

Step-4: Notice The Power Voltage Of Both 

Now notice the power voltage shown on the machine’s display. Be aware that the initial voltage power is significantly lower than the standard meter power. As opposed to the capacitor, high power voltage is expected, so don’t worry about this much. 

For the terminator, try to short the capacitor, and find a little spark produced from the capacitor. This indicates that the capacitor is in good condition and can hold enough energy. Thus, anyone can check the state of the ceiling fan’s capacitor.

Tips To Maintain Ceiling Fan To Avoid Early Capacitor Damage

Maintaining any electronic devices will produce long-term benefits. Similar things also happened when it came to the ceiling fans. Maintain the fan well. The capacitor will work more efficiently. So here are some tips for this. 

  • Clean It Once A Week 

Clean the ceiling fan once a week. Try to maintain this schedule from the very first day. Cleaning the fan’s wings and circuit boards will produce enough energy to keep it running. Also, it will help to prevent accumulated dirt. Dirt and junk may clog the capacitor if it continues longer.

Use a mild dishwasher cleanser and plain water to clean the fan’s external parts. Use a dry toothbrush and a clean rug to chaste the circuit box or other electrical components. 

  • Apply Lubricants 

A damaged motor may impact badly towards the capacitor. So try to use excellent and high-profile lubricants to keep it running. The fan’s motor gets stuck into the middle if they’re rusty. As one knows, rustiness is a common problem for metallic stuff. That’s why oil lubrication is an ideal way to prevent them. 

It also reduces the abrasions between two parts; the capacitor coil will be solid and practical after applying lubricants. 

  • Hang It With Well-balanced 

Be aware when choosing the place for hanging the fan. A wrong or dis-balanced may occur, the wobble problem of one’s fans. For a reason, the capacitor gets damaged due to continuous wobbliness or frizziness. Choose a place where the fan can spin or move freely. The fins especially need to be carried properly. 

Make sure to hang the fan in a well-balanced manner. Get help from an expert if it seems to be complicated.

  • Tightened All Screws 

When installing ceiling fans, properly tighten the wires, screws, and knots. Pulling them excessively may damage the fan’s motor. Whereas loosen screws often disclose a way to damage the circuit box and capacitor. Use a thin-headed screwdriver to tighten them.

It is helpful because thin-headed tools have become very handy for working over small parts. So check twice, even if one finished installing them correctly. 

  • Connect The Switch Wires Righteously

A wrong connection wire is probably the reason for the damage to the capacitor. It happens if anyone connects the red wire mistakenly to the black one. Again, the negative and positive ones will create short circuits. For this reason, be aware while connecting to the right one. 

Moreover, one might be aware of attaching the neutral line to the switch box.  Switch boxes have three primary lines: yellow, green, and black. Connect all those wires with the right proportions to prevent uncertain damage or overheating problems upon the capacitor.

What Is The Major But Common Sign Of A Faulty Capacitor Ceiling Fan?

One of the significant but common signs to tell about bad capacitors is overheating. If the switchboard provides excessive energy power through the wire, the capacitor may get hot or worn out. one may notice a melting or burning around the capacitor. 

Again, the lousy capacitor may cause the fans to spin in the midst. Furthermore, the fan wings get frizzy if the capacitor gets poorly damaged.

What Happens When The Ceiling Fan Capacitor Fails?

The most common sign of a faulty capacitor is to stop producing electricity to the fans. The ceiling fan can still spin and operate even if the capacitor fails. But it stopped spinning or moving like the previous

Moreover, a bad fan capacitor still has some power to run if one pushes it. Somewhere, one can try to beat the wings with a stick to help the fans’ fins to move or circulate.

Can A Ceiling Fan Run Without A Capacitor?

A ceiling fan capacitor can still run without a capacitor for its energy capacities. When someone manually tries to circulate the fan’s wings, it becomes running or moving on its own. Although a damaged capacitor is also a curse to one, it won’t make it cumbersome to handle. 

Additionally, fix the issues by directing the fan’s installation switches—the regulator of the fan’s used to direct the power level. Hence, the fan’s capacitor and regulator are connected. One can direct the regulator to use the lousy capacitor fans.

How Does one Check If A Capacitor Is Working Or Not?

Two processes can be used to check the worst or damaged capacitor. One can either identify them manually or use any multimeter or voltmeter tools. Observe the fan’s blade manually by continuously turning the maneuvering switch on and off to check its present condition. 

The capacitor is not in good condition if the fan spins or wobbles after turning on the switches. Secondly, one can check the power voltage of the capacitor by attaching them with any multimeter tools.

How Does One Test A Capacitor Without A Multimeter?

One of the best ways to test the capacitor without any multimeter is by using a terminator. Terminator is a prominent tool used to measure the voltage power in the capacitor. Unlike any multimeter tool, one must connect the red and black wire to the positive and negative ones.

After that connectivity, observing the present conditions of the capacitor will be easy. Meanwhile, be conscious of taking necessary safety; hence it tends to be dangerous for short circuit issues. Also, avoid touching the terminator with a bare hand after attaching the wires.

How Long Does A Ceiling Fan Capacitor Last?

A ceiling fan capacitor’s lifespan depends on its quality. Quality capacitors are more expensive than any cheap-rated Chinese products. There is one type of capacitor, and if used within its exact specifications, voltages, and temperature, it will never fail or be damaged. 

Together, a good quality capacitor lasts more than a year. Again, it may vary according to their materials and manufacturing affairs. Another significant fact that relies on the topic is well-maintained because this kind of voltage and lubrication will also contribute to its lifespan. 

Final verdict: 

Multiple indications and issues are related to the ceiling fan’s terrible capacitors. Some of them are indicated above to provide one with a hint. After finishing this article, I hope all the facts about identifying a bad capacitor ceiling fan may be clear now. 

Before wrapping up, I would like to add that I leave the idea of troubleshooting any damaged capacitor at home if I do not have enough experience. It would be better to replace the old one instead of following any worst DIY methods.
