Induction hob — symptoms, diagnosis and maintenance
An induction hob detects cookware, controls temperature and draws high power. Cracked glass, a burning smell or supply faults require stopping use.
Safety rule: stop when there is smoke, sparking, a burning smell, electric-shock signs, an active leak, cracked hob glass or suspected gas. Disconnect only when it is safe to do so.
