  2. Check the leveling of the countertop. Use a level tool to ensure the surface is even. Adjust the countertop if necessary, or use leveling shims under the cooktop to achieve a proper fit.

  3. If the cooktop is from a specific brand known for size variations (e.g., GE or Whirlpool), check for any manufacturer-recommended installation guides or adjustments. Contact customer service for advice on fitting issues.
