Kitchen light dimmer causes GFIs in kithcen to hum

Noticed recently that the GFIs in our kitchen hum slightly when we dim the lights in the kitchen - the humming goes away when the lights are turned up full. Any idea what causes this?

Are the lights on the same breaker? What kind of lights? How old are the GFCIs.

No, the lights are not on the same breaker. Regular bulbs and halogen bulbs, and the GFIs are new.

Could be the dimmer. Replacement is the sure way to check. Use a different brand of dimmer.
