Samsung Samsung AW06ECB7A 6,000 BTU Window Air Conditioner E9 Error Fix: Compressor Overload Protection

Error code E9 on the Samsung Samsung AW06ECB7A 6,000 BTU Window Air Conditioner means: Compressor Overload Protection. The compressor thermal overload has tripped. The compressor is overheating due to high ambient temperature, restricted airflow (dirty condenser coils), low refrigerant charge, or mechanical compressor failure. Allow the unit to cool for at least 30 minutes before restarting. Clean the condenser coils (outdoor side) with a brush. Ensure the unit is not recirculating hot exhaust air (requires proper window seal). If E9 recurs, the compressor or refrigerant charge may need professional service.
