- Stainless Steel Trim: Clean the 304-grade stainless steel trim with a soft cloth and a stainless steel cleaner, wiping in the direction of the grain.
- Control Knobs: The control knobs can be pulled off for easier cleaning. Wash them with warm, soapy water, rinse, and dry thoroughly before reattaching.
- Avoid Abrasives: Do not use abrasive cleaners, scouring pads, or sharp objects on the cooktop surface or trim, as these can cause scratches or damage.

- Ensure the control knobs are pushed down and rotated to an active setting.
- Burner not heating or heating slowly:
