Fagor induction hob makes loud buzzing or humming noises at certain power levels.

Safety first: Noise alone is not dangerous, but disconnect power before tightening internal components.

• Try different cookware: Use heavier, flat‑bottomed pans. Some noise is normal, but very loud buzzing may be reduced with better cookware.
• Change power level: Slightly adjust the power setting; noise often decreases at different frequencies.
• Check mounting: If noise is excessive, remove the hob and inspect coil mounting brackets and screws. Tighten any loose fasteners.
• Service if needed: If noise is accompanied by errors or heating issues, the power module may be failing and should be checked by a technician.
