Cooktop glass is cracked or shattered.

Safety first: Turn off power at the breaker immediately. Do not use the cooktop with cracked glass; this is a shock and fire hazard.

Steps to address:

• Do not operate: Avoid turning on any burners until the glass is replaced.
• Prevent cuts: Carefully clean up any loose glass fragments using gloves and a vacuum. Do not disturb the main glass surface.
• Order replacement top: Obtain the correct Viking glass top using the full model and serial number.
• Professional replacement: Glass replacement requires lifting the cooktop, transferring elements, and resealing; this is best done by a technician.

When to call a technician: Always. Glass top replacement should be performed by a qualified service provider.
