Potential causes include a malfunctioning doorbell transformer, loose connections within the unit, problems with the electric meter, issues with the incoming mains supply, or failing components inside the fuse box. While some buzzing sounds may be harmless, others can signal serious problems requiring professional attention. It's essential to have any unusual noises investigated promptly by a qualified electrician to ensure the safety and reliability of your electrical system.
