The blower fan is a vital component in your clothes dryer. In a gas dryer, this component consists of a drum-shaped fan that is connected to the motor by an axle. In an electric dryer, it is usually a plastic wheel that draws air over the heating element into the dryer drum. The wheel works in synchrony with the motor and creates a powerful air current. It draws air from outside the machine and circulates the air inside the drum to dry clothes. It then expels the air outside the machine through an exhaust vent. Whether yours is a gas or electric dryer, a bad blower wheel needs to be replaced. Below are 4 signs that indicate it's time to replace this component.
1. High Pitched Noise
You may hear a loud squealing or high-pitched noise from your dryer when you run it. In most cases, this can be traced to a faulty blower wheel. The blades of the wheel may become bent with time. They could also develop cracks or wear out at certain points. A faulty wheel strains as it spins which can cause high pitched noises to emanate from your dryer.
2. Loud Vibrations
Your dryer may vibrate loudly soon after the drum begins to move or right after it stops moving. It may even sound like there’s a pair of shoes inside the dryer. Sometimes the machine may also rumble when in operation. A likely cause of this noise is a worn out or damaged blower wheel. A damaged wheel spins out of sync with the motor. This may cause the dryer to rumble as it runs. However, sometimes the wheel may just be clogged with lint which can also cause noise when you run the dryer. Remove all dirt from the wheel and test it to see if the dryer is still noisy. If the noise persists, you’ll have to replace the wheel.
3. Dryer Doesn’t Dry Clothes Properly
Perhaps your dryer fails to dry clothes completely. You may feel some wet or damp areas when you remove your clothes from the dryer. This is usually traced to a damaged blower wheel. If the wheel is damaged or worn out, it is likely to create poor airflow within the dryer drum. The wheel will be unable to efficiently expel air and moisture from within the drum into the exhaust vent. This means that even when you set the dryer to run for a full cycle, your clothes will not dry completely. This calls for a wheel replacement.
4. Several Cycles Necessary to Dry a Load
This may be caused by poor or slow airflow through the dryer. Poor airflow is usually caused by a worn-out wheel. Most blower wheels have a D-shaped hole in the center. With time, this hole gets stripped out. This loosens the tension of the wheel as it spins on its axle. The wheel spins out of sync with the motor which causes poor airflow through the dryer. Poor airflow lowers the efficiency of the dryer.
If any of these issues are happening with your dryer, it may be time for a new blower wheel.
