Control knobs on Zline range are very hot to the touch during oven use.

Safety first: Turn off the oven and allow it to cool before inspecting seals and vents.

• Inspect door gasket: Check the gasket around the oven door for gaps or damage. Replace if worn.
• Check door alignment: Ensure the door closes evenly and seals against the gasket. Adjust hinges if necessary.
• Clear vents: Make sure top and rear vents are not blocked by foil, pans, or cabinetry.
• Cooling fan (if equipped): Listen for the cooling fan during operation. If it does not run, have it tested and replaced.

When to call a technician: If knobs remain excessively hot after gasket and vent checks, a technician should inspect internal insulation and airflow.
