What Does Error LC Mean?

The Amana air conditioner error code LC indicates a high temperature condition detected by the outdoor coil thermistor, often caused by low refrigerant levels or restricted airflow. This can lead to reduced cooling efficiency and may trigger protective modes in the unit. Symptoms include the display of the LC code, potential hissing sounds, and issues with airflow or the outdoor fan.

Common Symptoms:

  • Unit displays LC when outdoor coil temperatures are high or coil thermistor is over its normal operating range
  • Air conditioner may reduce cooling or go into a protective mode when LC is shown
  • Condition often associated with reduced airflow, hot condenser coil, or fan issues

Possible Causes

  • Outdoor coil thermistor high temperature condition (medium)
  • Restricted airflow or dirty/blocked coils (medium)
  • Outdoor fan malfunction (medium)

How to Fix Error LC

DIY Fix Check outdoor unit airflow and coil cleanliness

  1. Turn off power to the air conditioner at the breaker.
  2. Inspect the outdoor condenser coil for dirt, debris, or blockage.
  3. Clean the condenser coil gently with a brush or coil cleaner if dirty.
  4. Ensure there is adequate clearance around the outdoor unit for airflow.
  5. Restore power and observe whether LC clears after operation.

Technician Only Inspect outdoor fan and thermistor circuit

  1. Verify proper operation of the outdoor fan motor and blades.
  2. Check the outdoor coil thermistor resistance and compare to manufacturer specifications.
  3. Inspect wiring and connectors for the outdoor thermistor and control board.
  4. Replace outdoor coil thermistor or fan motor as needed if out of spec or failed.

Parts needed: Outdoor coil thermistor, Condenser fan motor, Wiring/connectors

🛑 When to Call a Pro:
  • If LC persists after cleaning coils and ensuring proper airflow
  • If outdoor fan does not operate or makes unusual noises
  • If thermistor or control wiring shows signs of damage
