P5: Compressor Overcurrent Protection Of Phase Current



Step 1: Check if System Undercharged

  • Evaluate the refrigerant charge level. An undercharged system can cause the compressor to overwork, leading to overcurrent situations.


Step 2: Check if System Overcharged

  • Assess the refrigerant charge to ensure it is not above the recommended levels. Overcharging can strain the compressor, triggering overcurrent protection.


Step 3: Check for Blocked Air Flow

  • Examine the system for any obstructions or issues restricting air flow. Inadequate air flow can contribute to compressor overcurrent situations.


Step 4: Check the Outdoor Fan Motor

  • Inspect the outdoor fan motor for proper operation. A malfunctioning fan motor can affect heat dissipation and contribute to compressor overcurrent protection activation.


Step 5: Check the Compressor

  • Evaluate the compressor for any signs of damage or malfunction. A faulty compressor can lead to overcurrent situations.


Step 6: Check the Outdoor Board

  • Examine the outdoor control board for visible issues or signs of damage. A malfunctioning control board can contribute to electrical irregularities triggering compressor overcurrent protection.
