Wall Connector emits a persistent humming or buzzing sound even when not charging

Safety: Mild hum can be normal, but sudden changes or loud noise warrant inspection.

• Compare to baseline: If the noise is new or significantly louder than before, consider it abnormal.
• Check mounting: Ensure the Wall Connector is firmly attached to the wall and that no panels are loose and resonating.
• Measure voltage: Have an electrician verify that supply voltage is within Tesla's specified range.
• If noise is excessive or accompanied by heat or smell: De‑energize the unit and arrange for replacement.
