How do I fix a Viking cooktop with a loose knob?

To fix a loose knob on your Viking cooktop, follow these steps:

1. Turn off the cooktop: Ensure the cooktop is powered off and cool to the touch for safety.
2. Remove the knob: Gently pull the loose knob off the cooktop control shaft.
3. Inspect the knob and shaft: Check for any damage or wear on the knob or the control shaft.
4. Tighten the set screw: If the knob has a set screw, use a screwdriver to tighten it securely onto the control shaft.
5. Replace the knob: Slide the knob back onto the control shaft and make sure it fits snugly.
If the knob remains loose or is damaged, consider contacting Viking's customer support or a qualified technician for further assistance.
