What Does Error C2 Mean?

The Amana air conditioner C2 error indicates that the compressor's overload protection has been triggered due to overheating. This is often accompanied by reduced cooling performance and unusual humming sounds. The issue is typically linked to poor indoor air circulation caused by restricted airflow, such as a dirty air filter or obstructions in the unit's intake and vents.

Common Symptoms:

  • Reduced or inadequate cooling performance
  • Airflow restriction sensed by the unit’s sensors or control board
  • Error appears in diagnostic mode display

Possible Causes

  • Restricted airflow due to dirty/blocked air filter or obstructed intake (medium)
  • Obstructions in unit’s airflow path (vents/return) reducing recirculation (medium)

  4. Check return vents and room layout to improve circulation

Technician Only Inspect airflow and sensor systems

  1. Verify airflow sensor readings and control board inputs
  2. Check duct/return airflow pathways for blockages
  3. Test indoor blower fan operation and air handler components
  4. Clean evaporator and blower assemblies if necessary

Parts needed: air filter, blower assembly, airflow sensors

🛑 When to Call a Pro:
