Metal cabinet feels unusually hot on the sides or top.

Safety: Surfaces may be hot; unplug before cleaning condenser.

• Check installation: Ensure the cooler has the required clearance on all sides and is not built into a sealed cabinet unless designed for built-in use.
• Clean condenser: If there is an exposed condenser at the back, clean it thoroughly.
• Ambient temperature: Move the unit to a cooler location if room temperature exceeds the specified climate class.
• Monitor: Some warmth is normal, but if surfaces are too hot to touch comfortably, reduce load and seek service if the condition persists.
