Display shows E8 and unit may shut down or limit operation, sometimes after long runtime in high heat.

Safety: Turn off and unplug the unit. Allow hot components to cool before touching.

Steps:

• 1. Improve airflow: Ensure the rear and sides of the unit have the clearance specified in the Danby manual (typically at least 12–20 inches). Move furniture or curtains away from vents.
• 2. Clean air filter: Remove and wash the air filter with mild soap and water. Let it dry completely before reinstalling.
• 3. Clean condenser coil: Remove the rear cover to expose the condenser coil. Use a soft brush or vacuum with a brush attachment to remove dust and lint from the fins. Do not bend the fins.
• 4. Check fan operation: With the unit reassembled and powered, observe the outdoor/condenser fan. It should start promptly and run at a steady speed. If it hesitates, runs slowly, or stops, the fan motor or capacitor may be failing and should be replaced.
• 5. Ambient conditions: If the room or outdoor temperature is extremely high, the unit may trip high-temperature protection more easily. Ensure adequate ventilation and avoid direct sun on the unit if possible.
• 6. Persistent E8: If E8 recurs after cleaning and verifying fan operation, there may be a refrigerant or sensor issue requiring professional service.
