R-Vent malfunction
R-Vent bearings worn
Worn bearings are a common cause of noise, vibrations, and a stiff motor in R-Vent ventilation units. Timely intervention can often prevent further damage to the motor.
- Grinding or squealing noise
- Motor runs stiffly
- Motor overhaul often possible
Symptoms of worn bearings
- Grinding, humming or squealing noise.
- A progressively louder hum.
- Motor runs stiffly or irregularly.
- Vibrations in the ventilation unit.
- Reduced ventilation performance.
How do bearing problems arise?
- Normal wear and tear from years of use.
- Dirt or dust around rotating parts.
- Moisture or contamination in the ventilation unit.
- Imbalance of fan or motor.
- Prolonged motor load.
When are bearings due for replacement?
A bearing that starts to wear often first makes a slight grinding or humming sound. As wear increases, hums, vibrations, and reduced performance become increasingly apparent. Therefore, do not wait too long to prevent further damage to the motor.
Are you unsure if the bearings are worn?
Use our troubleshooter or send us a photo of the type plate. We are happy to help you determine if an overhaul is the right solution.

For many R-Vent ventilation motors, worn bearings can be replaced during an overhaul. This means the complete ventilation unit does not immediately need to be replaced. This is often a more sustainable and more economical solution.
