GE air conditioner displays LO and may not cool or may run fan only

Steps:

• Check room temperature: Use a separate thermometer to verify actual room temperature. If the room is very cool (e.g., below 60°F / 16°C), this may be normal protection.
• Allow room to warm: If possible, allow the room to warm above the minimum operating temperature and try again.
• Sensor check: If LO appears even in a warm room, inspect and test the room thermistor. Replace if it reads much lower than actual temperature.
• Control board: If a new sensor does not resolve LO, the main control board may need replacement.
