User Suggested Solutions

  1. Check the power supply: Ensure the cooktop is plugged in and the circuit breaker is not tripped. If it is, reset it and test the cooktop again.

  2. Inspect the cookware: Ensure that the pots and pans used are induction-compatible (magnetic). Test with a magnet; if it sticks, it should work.

  3. Check for faulty components: If the first two solutions do not work, inspect the induction coil or burner element for damage. Replace if necessary.
