Verify that the Cavaliere hood is plugged into a working power supply if the hood or light does not operate. Turn the power switch to “On” and reset the circuit breaker if necessary.
Examine the hood if it vibrates when the blower is on and verify that it is securely attached to the wall or ceiling. Tighten if necessary according to the installation guide for your range hood.
Turn the power to “High” if the unit is on but is not venting properly during use or smoke remains in the air.
Contact an authorized service technician if the above steps do not resolve the problem. Other potential issues include improper distance between the stove top and bottom of the hood, improper duct sizing or a damaged blower.
These issues may require professional assistance.
