Range or cooktop vibrates, rattles, or feels unstable when burners or oven are in use.

Safety first: Ensure the range is cool before moving or adjusting it.

• Check leveling: Place a level on the cooktop front-to-back and side-to-side. Adjust the leveling legs at each corner until the range is stable and level.
• Verify anti-tip bracket: Pull the range slightly forward and then push back to ensure the rear leg engages the anti-tip bracket as per BlueStar installation instructions.
• Tighten components: Check that grates, burner caps, and oven racks are properly seated. Tighten any loose screws on side panels or backguard.
• Floor condition: If the floor is uneven or soft, consider reinforcing or shimming under the legs to provide a solid base.
