Electrolux Air Conditioner Error Code P5

P5 indicates that the overcurrent protection circuit for the compressor phase current has been triggered. The Intelligent Power Module detected current levels in one or more compressor phases that exceeded safe limits and shut the compressor down. This fault is also associated with IPM protection and loss of compressor synchronism faults, which share the same protective pathway. A technician should evaluate the compressor, IPM, and refrigerant system to identify the root cause.

No, you should not continue operating the unit while P5 is active. The error indicates the system has already shut down the compressor to prevent damage, and attempting to force operation could worsen the fault, damage the IPM or compressor, or create an electrical hazard. Leave the unit off until a qualified technician has diagnosed and resolved the cause of the overcurrent condition.

Repair costs vary widely depending on the root cause. If the fault is caused by something simple like a dirty condenser coil or a loose connection, costs may be minimal, covering only a service call fee in the range of $75 to $150. If the IPM module requires replacement, parts and labor typically range from $250 to $600. A compressor replacement represents the most expensive outcome, commonly ranging from $800 to $1,800 or more depending on unit size and labor rates.

Some checks, such as cleaning the condenser coil, clearing airflow obstructions, and inspecting wiring connections, can be performed by a knowledgeable DIYer. However, testing the IPM, measuring compressor winding resistance, and checking refrigerant pressures require specialized tools and technical knowledge. If the compressor or IPM needs replacement, a licensed technician should handle the repair due to the high-voltage components involved.

A power reset may temporarily clear the P5 code and allow the unit to restart, but if the underlying cause remains, the fault will return, often within minutes of startup. Repeated resets without addressing the root cause can accelerate wear on the compressor and IPM. A proper diagnosis of the compressor windings, IPM condition, and refrigerant circuit pressures is necessary for a lasting fix.
