None Air Conditioner: not spinning

Professional Repair Guide

What is this symptom?

If your air conditioner is running but the indoor or outdoor fan isn't spinning, you may experience inadequate airflow and poor cooling. This issue can stem from a failed fan motor, faulty wiring, or energy-saving modes stopping the fan. Understanding these causes can help you diagnose and resolve the problem effectively.

Urgency: Medium

Possible Causes

Part: Control board or fan power wiring

Indoor unit energy‑saving or sensor mode stopping fan
