Ceiling Fan Only Operates On High:Why And How To Fix It?

Ceiling Fan Only Operates On High:Why And How To Fix It?

We are all aware of how a ceiling fan can keep us cool during the heat. The breeze provided by the fan aids in cooling off our bodies. What if the ceiling fan is only capable of operating at high speed? How will you proceed?

Three reasons exist if a ceiling fan only operates at high speeds:

  • Issues with the control panel
  • Defective capacitor
  • Motor problems

We will go over each of these potential causes with you individually as we progress through this essay. Hold on tight as we go over other topics to keep your ceiling fan functioning properly.

Why Only High Speed Does Your Ceiling Fan Operate?

Are you still having trouble with this?

The Remote Control Box Is Having Issues

Nothing gets in the way of your leisurely afternoon like a broken ceiling fan remote or control box. What are you going to do then—pull the thread sometimes to alter the speed? You’re in luck since you can figure out the problem on your own.

Here is a simple troubleshooting step to restore the remote control.

  1. Examine the batteries and change them if necessary. This one should be evident.
  2. If it still doesn’t work, switch off both the fan and the circuit breaker box. You must check the dip switches this time.
  3. Find the receiver for the remote. It usually resides in the mounting bracket for the fan. Find the notched dip switches next. Remove the receiver, then look for other notches. Dip switches are what they are. It must line up with the remote control’s switches. Reinstall the receiver and verify the remote after you’re finished.
  4. If none of these work, you must get a new remote. There are models that fit your fan that are universal.

Why Is A Fan Capacitor Used For?
A ceiling fan uses two capacitors. The start capacitor is one, while the run capacitor is the other. Both are equally effective, but for different problems. The other capacitor controls the fan’s windings, while the start capacitor aids in jump-starting the phase shift of the fan.

How Can A Bad Fan Capacitor Be Repaired?
Be honest for a moment. Failure of a capacitor cannot be repaired. It can only be fixed by getting a new one. Beware, a faulty capacitor may cause significant electrical issues. As a result, the wire may burn, raising the possibility of a fire. The efficiency of your ceiling fan will decrease.

In order to fix it, check the wiring to see if it is in excellent shape. Call a repairman and have it rewired if you see poor wiring.

Motor Problems

In fact, you can replace the motor if it turns out to be the major issue. There are ceiling fan motors that can be plugged in and out.

Before you begin, make careful to turn off the breaker box. The old motor should then be removed and replaced with a new one once you have unscrewed the ceiling fan housing.

Here is a brief price comparison. Most ceiling fan motors range in price from $45 to $50. The majority of them cost about $110 or more. Given the price of the motor, it might be more economical to just install it rather than repeatedly perform troubleshooting.

How To Pick The Right Regulator For Energy Conservation

Together, a regulator and a ceiling fan should be used. There are various sorts of regulators, and there are various regulators for ceiling fans.

Regulators may not be a big deal to some people, but you should be aware that they might waste energy and cause your power costs to double.

You must first be familiar with the many sorts of regulators. Hold on tightly.

Digital Regulator

There are electronic regulators on the market; these are a more recent style of regulator and are more compact than electric ones. To lower voltage, these use capacitors as opposed to resistors.

Through the power supply’s waveform, the capacitors control the fan’s speed. It conserves electricity and doesn’t heat up. When using speeds 1 and 2, you can save at least 30% to 40% on electricity.

Two categories of electronic regulators exist:

  1. Movable Form: Easy to use but potentially dangerous is the movable type of electronic regulator, which regulates the distribution of power to your ceiling fan. The primary drawback of this kind of equipment is that it heats up excessively. However, it is typically utilized in houses and offices. Also simple to install is it.
  2. Step Form: When compared to the first type, this one is highly effective. It substantially aids in energy conservation.

When An Electronic Regulator Has Problems

You wouldn’t pay much for the electronic regulator, but most users have problems with this aspect of speed regulating. If the capacitor has problems or the circuit becomes faulty, you can choose the speed you desire by using the step regulator.

You should notify their customer care right away if there are any problems or faults because the majority of businesses offer good warranties.

When changing speeds with properly stepped electronic fan regulators, numerous transients are produced that are damaging to the capacitors in the fan. In order to alter the speed properly, you should turn off the switch, then turn it back on. Right, it seems weird. The regulator will last a long time because you will get used to it.

What to Do If There Are Problems With The Ceiling Fan Speed Control

Accurate wiring and electronic components are needed in order to change a ceiling fan’s speed. In order to mend or repair certain problems with the fan, you must take special care.

Even if some electronics are believed to be robust, using various speed controls seems to be a simple operation.

When you choose a speed, the controls offer several increments for each chain you pull. This mechanical process occasionally fails in a variety of ways. Fortunately, you may get a fan speed control at the lowest price. It is easily accessible online and in most hardware stores.

Here are some challenges with ceiling fan speed control you could run across.

Motor Voltage

Keep in mind that fans have either 120, 208, or 24 volts. Use the proper safety measures when working with ceiling fans. Always turn off the fuse or the circuit breaker before performing any servicing.

Simply label the fuse or the circuit breaker if you can’t see where the fan is from there. You might service the fan safely and effectively by using a ladder.


There are three categories of fan control circuits:

Continuous speed controls are used in electrical controls.

You should be aware of the following common ceiling fan components:

The connections of a motor winding are turned around by the reverse switch. This can be used in the winter since it draws air upward.

You can choose or regulate the speed with the speed control. You can select the speed you wish to go at with the speed control.
Despite having different capacitors, both of these are comparable. One of the key components of the fan that need maintenance is this one.


The next step is to assess the situation or problems with the ceiling fan speed control. One of the main causes of fans not operating is the presence of a faulty switch or entirely faulty capacitor.

The fan has a faulty capacitor if it only operates at one or two speeds. When the multiple section capacitor breaks down, the fan is unable to function effectively.

In many cases, your only option is to swap it out with a new one.


You now have vital information on how to handle a ceiling fan that has become stuck on high speed. To ensure continued good fan performance, regularly inspect the motor and capacitor. Additionally, make sure the fan’s primary components are in working order to prevent any severe issues down the road.
