Safety first: Isolate power before inspection.

Steps:

1. Inspect compressor connector: Ensure the multi-pin connector is fully seated and not heat-damaged.
2. Listen for abnormal noise: If the compressor was noisy or vibrating excessively, it may be failing mechanically.

Further diagnosis requires a technician to test inverter signals and compressor windings and replace the faulty component.
