Why Outdoor PCB Failure Disrupts AC Performance

Your outdoor unit’s PCB is the central control system, and when it fails, the AC may experience:

• No cooling or weak cooling

• Compressor not starting

• Outdoor fan not running

• Tripping, blinking lights, or error codes

• High energy consumption

• Sudden system shutdowns

Replacing a faulty PCB is essential for stable, efficient cooling and to protect the compressor.
