What Does Error LS Mean?

The Amana Air Conditioner LS error code indicates that the unit has engaged its load shedding mode, disabling the compressor and heating outputs to protect against overload. This may result in warm air being produced and the display showing LS. The fan may still operate, but cooling or heating will be unavailable. This condition is often a response to external load control measures.

Common Symptoms:

  • Unit displays LS on digital panel or control board
  • Compressor and electric heat outputs are turned off
  • Airflow or fan may still operate but cooling/heating output is disabled

Possible Causes

  • Load shedding switch is engaged (medium)

How to Fix Error LS

DIY Fix Check Load Shedding / Switch Position

  1. Locate the load shedding switch or panel for your unit (often on the chassis or control panel)
  2. If accessible, ensure the switch isn’t closed/engaged
  3. If it is engaged due to external load control (e.g., utility load shedding), wait or reset per unit documentation

Technician Only Verify Load Shedding Circuit and Controls

  1. Confirm that the LS mode isn’t triggered by an external load control signal or internal protective circuit
  2. Inspect wiring and sensor inputs related to the load shedding function
  3. Test the control board and switch continuity to ensure proper operation
  4. Reset control logic and verify normal compressor and heat sequencing

🛑 When to Call a Pro:
  • LS condition persists after resetting the load shedding switch
  • Unit still fails to operate normally after power cycle
  • Signs of electrical damage, burning smell, or repeated protective cutouts
