Error Codes
Code Faulty description Faulty checking Faulty repairing
E1 T1 sensor open circuit Check the wiring and connection between
PCB and sensor, if it is open circuit.
If the connection and wiring are normal, replace
the sensor.
E2 T1 sensor short circuit Check the wiring and connection between
PCB and sensor, if it is open circuit.
E3 T2 sensor open circuit Check the wiring and connection between
PCB and sensor, if it is open circuit.
E4 T2 sensor short circuit Check the wiring and connection between
PCB and sensor, if it is short circuit.
HI Inner temperature too high
1. Display on both compartment:
a. Check if any refrigerant leakage. a. Repair the leakage.
b. Check if the capillary jam. b. Clean or replace the capillary.
c. Check the evaporator fan. c. Replace the evaporator fan.
2. Display on lower compartment: Check
the lower fan
If the fan is broken, replace it.
LO&CL Inner temperature too low Check if the PCB is normal. Replace the PCB.
