Generator shuts down after several hours with a strong hot smell but no specific code

Safety first: Turn controller to OFF, open main AC breaker, and allow the unit to cool fully.

• Inspect ventilation: Ensure that all louvers and vents on the enclosure are clear of debris, snow, or vegetation. Maintain the clearances specified by Westinghouse around the unit.
• Clean cooling surfaces: For air-cooled units, blow out dust and debris from cylinder fins and shrouds. For liquid-cooled units, clean the radiator fins with low-pressure air.
• Check for obstructions: Remove any stored items or structures that may be blocking airflow around the generator.

If shutdowns continue in hot weather, a technician should verify cooling system performance.
