Exterior of the coffee maker becomes excessively hot to the touch during brewing.

Safety first: Unplug the unit and allow it to cool completely before inspection.

• Check placement: Ensure the coffee maker is not placed in a confined space or against walls that trap heat.
• Inspect vents: Clean any dust or debris from vents.
• Internal inspection: Remove the housing and verify that any reflective heat shields are in place and not bent away from the heater.
• Heater alignment: Confirm that the heater tube is properly mounted and not touching the plastic housing directly.
• Thermostat check: If overheating persists, the thermostat may be failing to regulate temperature and should be replaced.
