Samsung P4 Error: Indoor Unit Overload Protection

Understanding the P4 Error

The P4 error code on your Samsung inverter air conditioner signifies an overload protection issue with the indoor unit. This error can severely impact the cooling efficiency and overall performance of your AC unit, necessitating prompt attention to avoid further damage.

Causes of the P4 Error

1. Clogged Air Filters: Dirty or clogged air filters restrict airflow, causing the indoor unit to overwork and trigger overload protection.
2. Blocked Air Vents: Obstructions in the air vents hinder proper airflow, leading to overheating and overload.
3. Faulty Fan Motor: A malfunctioning fan motor can result in inadequate cooling and overload of the indoor unit.
4. Electrical Issues: Problems with wiring or electrical components can cause the indoor unit to overload.
5. Refrigerant Issues: Imbalanced refrigerant levels can stress the indoor unit, activating overload protection.
