- Grinding or squealing noise
- Motor runs heavily
- Bearing replacement often possible
What do you notice?
- The ventilation unit makes a grinding, humming, or squealing noise.
- The noise becomes progressively louder over time.
- The motor runs heavily or starts with difficulty.
- The ventilation unit may extract less effectively.
Possible causes
- Normal wear and tear from years of use.
- Dirt or dust around moving parts.
- Bearings that are dry, worn, or damaged.
- Motor strain due to imbalance or contamination.
What can you safely check yourself?
Pay particular attention to the type of noise. A grinding, humming, or high-pitched sound often indicates bearings. If the motor runs heavily or no longer starts properly, it is advisable to have the unit inspected. Always disconnect the ventilation unit from power before checking anything.
