Samsung Error Code E231 / 231

If your Samsung unit shows Error Code E231 (or 231), it often points to low pressure protection or refrigerant performance issues. This may be caused by low refrigerant levels, leaks, airflow restriction, or compressor performance problems.

Symptoms include weak cooling/heating, longer run times, icing, and system shutdowns. If the system is losing refrigerant, performance typically worsens over time.
