P5: Compressor Overcurrent Protection Of Phase Current
P5 TROUBLESHOOTING STEPS:
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.
