Vent Hood - Flickering Lights

If the lights on your vent hood are flickering, this is most likely a normal occurrence. We are explaining this below.

 

Understanding Flickering Lights on a Vent Hood

Although uncommon, is can be normal for the lights on a vent hood to flicker. Voltage going to the lamp while the vent is on the LOW setting passes through an electronic component called a diode. The diode cuts the power by half to achieve the dimmer setting.

 
  • The flicker is a very, very fast flicker.
  • It is usually perceived not by looking directly at the lights but by focusing your eye on something near the lights, especially something highly reflective like the cooktop underneath the lights.
  • This issue cannot be resolved by replacing either the bulbs or the hood.
