Why does my Cosmo COS-QS90 have poor performance?
- SStacy HaydenJul 28, 2025
Several factors can cause poor performance in your Cosmo Ventilation Hood: * If the distance between the hood and cooktop is not optimal (24” to 36”), adjust the distance. * Close some open doors or windows to prevent air flow interference. * If the motor performance has decreased due to wear, consider replacing the motor. * Ensure that the tape holding down the damper flaps at the vent hole are removed before use.
