Knobs or bezels discolor, melt, or deform during high oven or broiler use.

Safety first: Turn off the oven and allow all parts to cool before touching damaged components.

• Inspect door seal and hinges: Ensure the oven door closes fully and the gasket is intact to prevent heat from venting directly onto the control panel.
• Check heat shields: Some BlueStar models use metal shields behind or under knobs. Verify they are present and correctly installed.
• Use correct knobs: Replace damaged knobs with genuine BlueStar high‑temperature knobs designed for your model.
• Broiler use: Follow the manual’s instructions for broiling; do not operate with the door open unless explicitly specified.
