Unit is very warm to the touch on the sides or top, but interior is cooling normally.

Safety note: Warm cabinet walls can be normal, but they should not be dangerously hot.

• Check installation: Ensure the cooler has the recommended clearances on all sides and is not enclosed tightly without ventilation.
• Measure temperature: Warm to the touch is normal; if surfaces are too hot to touch comfortably, improve ventilation and check condenser fan operation.
• Monitor performance: If interior temperatures remain stable and within setpoints, this is likely normal operation for models with side-wall condensers.
