Chigo Air Conditioners Error Codes

The CHIGO air conditioning control system indicates any malfunctions through the LED lights on the indoor unit panel. Each detected malfunction corresponds to a specific sequence of LED lights or flashes, representing the error code. In case multiple errors are detected, the control system prioritizes and displays the fault with the highest priority first.

Error codes for wall split systems:

• Room temperature sensor: blinks 1 or lights for 8 seconds (Display: E2)
• Evaporator Temperature Sensor: blinks 2 or lights for 8 seconds (Display: E3)
• Air conditioner overheating: blinks 3 or lights for 8 seconds (Display: E8)
• Pump (Overflow): blinks 4 or lights for 8 seconds (Display: E9)
• Fan motor: blinks 6 or lights for 8 seconds (Display: E5)
• No communication with external unit: 7 blinks / 8 seconds (Display: E7)
• Lid not closed: glows or blinks 3 for 8 seconds (Display: E0)
• Condenser temperature sensor: glows or blinks 4 for 8 seconds (Display: E1)
