Can install a ceiling fan without a ground wire? How to balance a ceiling fan

Before modern products, when you didn’t have a ground wire, that seemed impossible. In the article of Toby Nwazor at, will give easy instructions to install a ceiling fan without a ground wire. At the same time, you can also follow the simple steps below to keep your ceiling fan balanced.

How to install a ceiling fan without a ground wire

With different terrain types, there will be different ways to install ceiling fans without ground wire. From there, we will figure out how to balance the ceiling fan.

Install a ceiling fan without a ground wire.

For concrete ceiling fan

How to install ceiling fans without hooks on concrete ceilings is too easy. Because the concrete ceiling has the ability to withstand a large light load, it is built solidly and firmly with many layers of beams and steel, so you can comfortably install it without worrying about safety problems. 

  • Preparation: Electric drill, 8 mm diameter concrete drill, Ø8x40mm bolt and bar.
  • Perform:

– Determine the installation position of the ceiling fan in accordance with the room space, ensure that there are no objects within the rotation range of the fan, the height from the fan blade to the floor is from 2.3 to 2.7 meters. Pay attention to choose the mounting position with the power cord.

– Accurately measure the size of the fan disc and drill 2 holes, install the prepared spacer in the position just drilled, making sure the pad is flat against the ceiling.

– Install 3 rubber wires into the 3 available hole positions on the ceiling fan disc, then thread the wire through the center hole of the fan disc.

– Align the two bolts in line with the hole in the bare disc, push the bare disc into the bolt so that the rubber seal presses against the ceiling. Carefully tighten washers, spring washers and nuts to bolts to secure.

For plaster ceiling fan

The biggest drawback of gypsum ceilings is their lower bearing capacity than concrete or wooden ceilings. Therefore, installing a ceiling fan without a hook with a plaster ceiling also needs “tricks” to ensure safety, avoid falling, and danger to users.

  • Preparation: ceiling fan, hanger, drill, screw, bullet expander, ti tree, electric tester… you can strip a small tarp on the floor to avoid dust and dirt on the house.
  • Perform:

– On the plaster ceiling, you drill a hole about as wide as the mouth of a small bowl. Doing this will not lose the aesthetic of the ceiling because the fan will cover this hole. Just note that do not cut too big, especially when installing at the position of the plaster tray. very easy to damage your drywall ceiling.

– Next, you thread the drill along the hole and drill 2 holes with a depth of about 6 cm into the concrete ceiling. Depending on the ammunition you have, you can use an 8 or 10 mm drill. Then close the bullet into the drill hole.

– Measure the iron thread from the bullet to the lower surface of the plaster and add 4 cm. Then tighten the iron thread on the bullet hatch.

– Take 2 canopies to fit to the plaster surface to prevent the flange from coming off. Next will install the flange and tighten the screw under the flange, fix the flange

– Install the fan on the flange and rotate it so that the fan blade and the tooth joint of the flange are tight.

– Electrical connection, light connection, safety wiring and finishing.

For wooden ceiling fan

When installing ceiling fans without hooks for wooden ceilings, you must check their certainty before proceeding with the installation. With wooden ceilings, you should also choose a ceiling fan with a moderate weight.

  • Preparation: electrodynamics drill, wood drill bit with a diameter of 0.3 m, 2 screws 0.4×40 mm, washers, 1 wooden stick 4×8 mm.
  • Perform:

– Measure the exact size of the bare disc and then drill 2 holes into the wooden lever.

– Install 3 rubber gaskets into the three available hole positions on the ceiling fan disk and thread the power cord through the hole in the center of the electric fan disc.

– Adjust the position of the ceiling disc for the holes to match the position of the drill hole, tighten the ceiling disc to the ceiling with screws with washers.

For tile or corrugated iron ceiling fan

First, you must determine whether the tile or corrugated iron ceiling has pre-existing termites to install a ceiling fan. If not, you need to prepare a purlin or iron bar to put on the ceiling so that it is right in the center of where the fan needs to be installed. Then use the thread to hook on the newly made purlin and install the flange.

Note when installing a ceiling fan without a ground wire

Ceiling fans are not necessarily important, but they are unique electrical devices because of their installation and operation, as well as their role as luxurious decorative items in the home. It is a fan hanging upside down on the ceiling instead of placing it on the ground or hanging on the wall like other devices. Installing a ceiling fan with a hook has been a challenge for many people. So, how to install a ceiling fan without a ground wire? Is there any equipment needed to install a ceiling fan on a plaster ceiling without a hanger?

To handle the case that the ceiling does not have a hanger available, the manufacturer has researched to produce ceiling fans with simple and effective mounting specifications. Some types of ceiling fans not only have a cooling function but are also decorative items to create aesthetics for the room, so flanges are often used as mounting points.

This flange will stick directly to the ceiling of the house, using bullets to help the ceiling fan withstand the weight of the fan, so you don’t have to worry about the problem of falling. In addition, the flange also helps to balance the propeller without worrying about shaking.

If your ceiling is plastered, you should contact the installation department of the company that supplied the ceiling fan. A team of professionals will always have the best method to install a fan for the family.

Note, when there is no ground wire, the ceiling fan must be mounted directly to the building structure or sturdy beams. These beams must support a minimum fan weight of 16 kg. During installation, use only genuine accessories and strictly follow the instructions of the manual.

How to balance a ceiling fan

A well-balanced ceiling fan will spin overhead and keep you cool for hours without making a single noise or crash. Can even be used in winter for better distribution of heated air by turning south-north.

Basic knowledge of unbalanced ceiling fan repair

Ceiling fans can be very close to balance, but no ceiling fan is perfectly balanced. Because your ceiling fan rotates from a central axis, this rotation helps correct certain imbalances in the fan. Some degree of wobble is considered normal and not necessarily a disability. When the fan imbalance exceeds the allowable level, the fan will sway more than necessary and will make noise.

Parts that affect ceiling fan balance

  • While most ceiling fan imbalance problems can be traced back to the fan blades, it’s a good idea to check the entire fan first.
  • Fan body and housing must be sealed and in good condition. The propeller brackets need to be fastened to the fan body.
  • Impellers should be inspected to ensure that they are not cracked or delaminated. You should also make sure that each blade is securely attached to its holder.
  • Most ceiling fan imbalance problems are caused by incorrect and inconsistent fan blade levels. The impeller mounting bracket to the fan motor assembly may need to be bent back to its original position.
  • Some unbalance problems also occur when the entire motor-fan assembly such as the one below the slider is out of balance. The fix is ​​to attach metal adhesive or a weight clamp from the ceiling fan balancer to the top of the fan blade. This set sometimes comes with a ceiling fan or is available from the manufacturer or home center.

Things to do to keep the fan balanced

Safety Considerations

Always turn off the power to the fan before working. It is always safest to turn off the power to the fan with its circuit breaker, at the warranty panel. Do not attempt to bend the blade frame to an abnormal position.

Clean the propellers

From the top of the ladder, check the tops of the blades. Over time, the blades will collect dust and other debris in the air. Gently clean the dust, being careful not to tamper with or bend the fan blades, brackets or body. Any debris dispersed inconsistently between all blades will cause the blades to wobble. For example, this could include a large swarm of cobwebs found on only one blade.

Check fan body and housing

Make sure that the ceiling fan’s power is turned off at the breaker. Manually check the connection to the ceiling to make sure that the fan is not loose relative to the ceiling. Only check the upper part of the drop bar, do not check the lower part with the motor and propeller. This upper should fit snugly and snugly against the ceiling.

Check and calibrate propeller height

Stand on the steps next to the ceiling fan. With a straight edge or tape measure, measure the distance from the tip of the blade to the ceiling, just above. Since the blades are angled, choose a point on the blade and be consistent as you move through all the blades. The distance of the fan blades from the ceiling should not be more than 1/8 inch apart.

Check propeller connection

Make sure that the screws that attach the propeller to the bracket and the bracket to the motor hub are tight. Tighten these blades if necessary with an Allen wrench or screwdriver.

Check and adjust fan’s overall balance

The ceiling fan’s suspension sphere is designed to maintain the overall balance of the motor hub. Run a laser line from the laser level on all propellers. Turn the fan on and off to spin the blades and check the level again. If the unit is unbalanced, use the weight from the balancer to add weight to the individual blades to balance the unit. Rotate the arms by hand several times to verify that the unit is level.

How to deal with an unbalanced ceiling fan

Ceiling fans are shaken when operating, which will reduce the coolness, causing discomfort to the people in the room, even for many people this is also an “obsession” because of the fear that the fan may fall anywhere. when. If you are also facing the problem of the ceiling fan being loud and shaking, continue reading the article below to know the cause and how to fix it!

Necessary steps to take when the ceiling fan is shaking

When detecting that the ceiling fan shows signs of shaking, unstable, you need to find a way to fix it immediately, not let this situation last because it will directly affect the process of using the fan in the common space.

  • Step 1: Stop using the fan to check for errors to ensure safety, do not try to use it because it is easy to damage the fan further, and may even cause the fan to fall, causing many dangers.
  • Step 2: Consider the cause and find the appropriate “cure”.
  • Step 3: After the repair is complete, restart the fan to check if the fan shaking phenomenon is still there. If the problem persists, you should contact a professional ceiling fan repair center to fix it in time.

The cause and how to fix the ceiling fan is shaking or making noise

A shaking ceiling fan can be caused by a manufacturer error or installation error, or it may be due to a long period of not being maintained. Here are some common causes of ceiling fans shaking and how to fix them.

How to fix the ceiling fan shaking or making noise
Uneven fan blades

This is due to a manufacturer’s fault. Irregular fan blades will cause the ceiling fan to lose its balance in weight, the difference being too large will affect the rotating shaft and over time will cause the shaft to wobble, leading to fan vibration.

  • How to fix:

– Use a tape measure to measure the distance from the ceiling to the fan blade, note the measurement at the end of the blade.

– Measure in turn for each propeller, if any propeller has a larger distance, that blade needs to be handled. Check the weight of the propellers, if necessary you should replace the other propeller with a balance in weight. You can contact the place that sells the ceiling fan or buy a replacement blade to overcome the shaking caused by the weight imbalance.

The impeller joints are uneven

This is also a cause of the ceiling fan shaking. The principle to ensure that the fan operates smoothly and efficiently is that the connection points of the fan blades must be even.

  • How to fix:

Replace the propeller with a new one or adjust it properly. You can have a professional check and reinstall it. If you have enough knowledge and experience, you can adjust the arm, using a slight force to adjust the arm to have the same distance as the other wings. If we have processed the arm bending and it still does not work, we will have to use the wing balance patch.

Loose screws

The screw system is an important element to securely hold the ceiling fan. Therefore, if the screw is loose, it will cause the ceiling fan to shake, making it unsafe to operate.

  • How to fix:

Use a professional tool to re-tighten the screws and check more of the lampshades and bulbs on the ceiling fan to make sure there is no looseness that causes the ceiling fan to buzz. and shake.

The screws on the hanger and rubber gasket are too tight

Few people think that the tightening of the screws in the hanger and the rubber gasket is also the cause of the shaking of the ceiling fan. With screws and rubber gaskets, you should install only moderately tight.

  • How to fix

You should ask a professional installer to loosen the loose screws because the rubber cushion is intended to absorb movements, ensuring anti-vibration.

Engine unbalanced

The motor is an important part of the fan, there needs to be a new balance to help the ceiling fan work well. If you find that the ceiling fan is shaking, check the motor system to see if it is stable.

  • How to fix

Never install more than one propeller at the same time.

Too much dirt

Leaving the ceiling fan in the dining room, kitchen… for a few months or a few years without cleaning and sanitizing, the ceiling fan is very susceptible to dirt. Layers of dirt build up on top of each other, adding an extra weight to the fan, which can lead to weight imbalances on fan components and cause the fan to shake.

  • How to fix

Clean the ceiling fan every 3 months or every 6 months. When cleaning, disconnect the power, remove it gently and install the fan in accordance with the process and technique. See details: How to clean a ceiling fan simply and effectively. The length of the hanging pipe is not standard.
