Speed reduction is a common problem of a ceiling fan. There are several reasons for decreasing the speed of your ceiling fan over time. They can be made faster and more efficient by performing a few basic maintenance tasks.
It might be not very pleasant on a summer day if you feel your ceiling fan cannot produce enough airflow. With some basic maintenance, your fan speed might boost. Even you might not need to change the capacitor for speeding up your fan.
In this article, you will know why a ceiling fan can decrease speed and how to increase motor rotation. Follow our step by step guidelines below.
Step 1: Clean the fan blades.
If your ceiling fan blades are not clean, first, clean the blades. A thick dust layer can impact the rotation of the fan. Every year, you should clean your fan three times. Besides, check the blade’s screws and make sure all the screws are tightened enough.
Cleaning the fan blades might be annoying if you do not follow the proper way. The floor and the furniture of your room might be dirty. But there are easy ways to clean.
A pillowcase might be the most effective way to clean a ceiling fan’s blades. To reach the fan:
- Use a step ladder and insert one blade into the pillowcase.
- Wipe the blade from bottom to top. The pillowcase will catch all the dust, and your room will not be dirty.
- Repeat the process with the remaining blades.
Step 2: Balance the fan blades.
There are different types of fans for use in different places. If you install a dry-rated fan in a place where you need a damp-rated or wet-rated fan, it will start rust quickly and make an unbalancing. With the unbalanced blade, you might face the same problem.
Now you need to make sure proper balancing of your fan. However, if the blades have been damaged by hitting something or for the weather, it’s better to replace them.
If the condition of the blades is good, you can easily balance it using balancing kits. Add this kit in different blades and notice which blade is unbalanced. This is a small piece of weight. After identifying, you need to add accurate weight permanently. Your fan will return to its average speed once it has been appropriately balanced.
Step 3: Lubricate your ceiling fan.
This step is not for all fans. If your ceiling fan required manual oiling, then you need to check this step. But the question is, how you will understand your ceiling fan might need to add oil?
If you notice your ceiling fan creates noise even at a low speed. That means the fan needs oiling of its parts. Some old ceiling fans and some Hunter ceiling fan models have oil reservoirs. From this reservoir, flow the oil in different moving parts. That not only reduce noise but also ensure maximum speed.
Set up a step ladder to reach the fan and find a small hole at the top of the motor housing. You need specific oil for your ceiling fan. You have to use non-detergent oil, and you can also use Hunter’s original ceiling fan oil.
Step 4: Capacitor.
This is the most common cause for the low spinning of a fan. If the capacitor goes down, you can’t fix it. You have to replace your bad capacitor with a new one.
Capacitors lead to the start of the ceiling fan and can control the fan rotation. Some fans have a single capacitor and some multiple capacitors in parallel. Overuse or wear and tear can cause them to break down over time.
First, remove the existing capacitor, purchase the same rated capacitor from the local store, and then replace it.
Step 5: Bearings/Bushings.
Another reason for slow spinning is bad bearing and bushing. When the bushings or bearings in your ceiling fan wear out, it makes a loud squeak. Before you replace bearings, identify the type of bearing. And also, check bearing lubrication; if you see it is dry, lubricate it.
Step 6: Check before the next step.
Turn the fan on to check the previous steps are worked or not. If you see there is no noticeable change, go to the next step.
Step 7: Check the pull chain.
Check speed control pull-chain switch. Sometimes it might fail to control speed. In that case, you can change the pull switch.
Step 8: Check the motor.
After replacing the switch, if the problem was not solved, inspect the motor windings. The windings can control fan speeds. If there is any wrong winding, you need to rewind the motor by a professional.
If you see the speed dramatically drop, most probably you need to change the capacitor. For slightly falling down with noise, the chance of lubrication is very high. If you can make sure of regular maintenance, a ceiling fan will provide you with smooth performance for years after years.
