AGA induction cooktop zone shows F8 and will not heat properly

Safety first: Turn off the cooktop at the mains and allow it to cool fully before inspection.

• Check ventilation: Ensure there is adequate clearance under the worktop and that the cooling vents for the AGA induction module are not blocked by insulation, pans, or drawers.
• Inspect fan operation: Turn power back on and run a zone at low power. Listen for the cooling fan. If the fan does not run or is noisy, it may be seized or failed and should be replaced.
• Pan suitability: Use a flat-bottomed, induction-compatible pan that fully covers the marked zone. Avoid very small pans on large zones.
• Reset: Power off for 10 minutes, then retry. If F8 returns quickly, the module may be overheating due to a failed fan or internal fault.

When to call a technician: Accessing and replacing the induction fan or power module involves live high-voltage components. This should be done only by a qualified engineer.
