Possible Causes

Impact from heavy cookware, Thermal shock from cold liquid on hot surface, Improper installation support

How to Fix / Troubleshooting

Safety first: Disconnect power and, for gas units, shut off gas. Do not use the appliance with a cracked glass surface; risk of electric shock or gas leak increases.

Steps:

  • Assess damage: Inspect the extent of cracking or warping. Any crack that reaches the edge or crosses a burner zone requires replacement of the top.
  • Order correct top: Obtain the exact OEM glass or stainless top for your Sub-Zero/Wolf model and color/finish.
  • Replace top: Remove knobs, trim, and mounting screws. Carefully lift off the damaged top and transfer components (burners, elements, gaskets) to the new top as per service instructions.
  • Check support: Verify that the cooktop or range is properly supported and level to prevent stress on the new surface.

Note: Do not attempt to repair cracks with adhesives; replacement is the only safe option.
