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
- Check room temperature with an accurate thermometer
- Ensure the dehumidifier is placed in a space above the manufacturer’s specified minimum temperature
- Move unit to a warmer location if necessary
DIY Fix Relocate and adjust placement
- Avoid placing the unit on cold concrete floors or near cold drafts/windows
- Elevate on a platform or place away from exterior walls to minimize cold-sensor influence
Technician Only Inspect/Replace ambient temperature sensor
- Disconnect power and access internal sensor wiring
- Verify ambient temperature sensor position and secure connections
- Test sensor with multimeter against expected resistance/response at known temperatures
- Replace sensor if readings are inconsistent with actual temperature
Parts needed: Ambient temperature sensor
- If LO persists despite ambient temperatures being within normal operating range and sensor tests are inconclusive, contact GE service or qualified technician.
