What Does Error LO Mean?

The LO error code on your GE dehumidifier indicates that the unit has detected a low ambient temperature, preventing the compressor from starting. This lockout occurs when the surrounding temperature falls below the manufacturer's specified operating range, typically around 41°F. While the display shows 'LO', the dehumidifier will not function, as it is designed to protect itself from damage in cold conditions.

Common Symptoms:

  • Display shows LO on screen
  • Compressor does not start
  • No dehumidification activity while LO displayed

Possible Causes

  • Ambient temperature below operating range (medium)
  • Faulty or misreading ambient temperature sensor (medium)

How to Fix Error LO

DIY Fix Verify operating environment

  1. Check room temperature with an accurate thermometer
  2. Ensure the dehumidifier is placed in a space above the manufacturer’s specified minimum temperature
  3. Move unit to a warmer location if necessary

DIY Fix Relocate and adjust placement

  1. Avoid placing the unit on cold concrete floors or near cold drafts/windows
  2. Elevate on a platform or place away from exterior walls to minimize cold-sensor influence

Technician Only Inspect/Replace ambient temperature sensor

  1. Disconnect power and access internal sensor wiring
  2. Verify ambient temperature sensor position and secure connections
  3. Test sensor with multimeter against expected resistance/response at known temperatures
  4. Replace sensor if readings are inconsistent with actual temperature

Parts needed: Ambient temperature sensor

🛑 When to Call a Pro:
  • If LO persists despite ambient temperatures being within normal operating range and sensor tests are inconclusive, contact GE service or qualified technician.
