Common Symptoms:

  • Air conditioner stops cooling and displays ‘P2’ on panel
  • Unit may shut down after running for a period
  • Compressor protection may be triggered

Possible Causes

  • Over‑current protection (operational current exceeds allowed limit) (medium)
  • High temperature / compressor protection event (medium)
