Induction cooktop overheat protection; zone shuts off and displays C-33.

Safety first: Turn OFF the affected zone and allow the cooktop to cool. If there is any burning smell, disconnect power at the breaker.

Cooling and usage:

• Remove cookware and let the cooktop cool for 30–45 minutes.
• Ensure vents under and behind the range are not blocked.
• Avoid running multiple zones at maximum power for extended periods if ventilation is limited.

Inspection (advanced):

• Check the cooling fan operation when the cooktop is in use; you should hear it running at higher power levels.
• If the fan does not run, inspect and replace the fan as needed.
• Inspect the coil temperature sensor and wiring for damage or loose connections.

Professional help: Persistent C-33 errors even with good airflow and a working fan may indicate a failing induction power module that should be replaced by a technician.
