Air Conditioner E8 Error Code: Overload Protection or Anti-Freeze
Quick Answer
E8 on window and portable air conditioners typically indicates overload protection or anti-freeze protection. GE window ACs use E8 specifically for compressor overload. Other brands use E8 for evaporator freeze protection (the indoor coil is icing over). Causes of evaporator freezing: low airflow from dirty filter, low refrigerant charge, or running the AC in ambient temperatures below 60F.

Other brands use E8 for evaporator freeze protection (the indoor coil is icing over). Causes of evaporator freezing: low airflow from dirty filter, low refrigerant charge, or running the AC in ambient temperatures below 60F. If the indoor coil has visible ice: turn the AC to FAN ONLY mode for 1-2 hours to melt the ice. Do NOT run cooling mode with a frozen coil. After defrosting, clean the filter and verify airflow is not blocked.
