• Code: E004-0301
• Description: IH overcurrent detection error. Detected an overcurrent on IH power supply board.
• Remedy: 1. Faulty fixing belt unit -> replace the fixing belt unit 2. Faulty fixing IH unit -> replace the fixing IH unit 3. Faulty IH power PCB -> replace the IH power PCB

• Code: E004-0401
• Description: 12V failure error. Detected abnormality on the 12V power supply line.
• Remedy: 1. Check the fixing belt -> if it is damaged, replace the fixing belt unit 2. Check the connection of the fixing fuse PCB -> replace the fuse PCB 3. Check the connection of the fixing thermoswitch (TP2) (thermoswitch is OFF, or the cable is disconnected) -> replace the fixing belt unit 4. Relay PCB replacement 5. DC controller replacement 6. IH power supply replacement

• Code: E004-0501
• Description: Fixing belt temperature difference error 1. Difference of detected temperature between the fixing subthermistor -2 (THM1-3) and the fixing subthermistor -1 (THM1-2) is bigger than the rated value.
• Remedy: 1. Fixing main /sub thermistor (THM1-1/2/3) connector disconnetion (pinching wire, broken wire) -> replace the fixing belt unit 2. Check the rotation of the fixing motor (to see if the connector is physically removed or disconnected) -> replace the fixing motor or the harness 3. Faulty drawer connector -> clean the drawer connector or replace the fixing unit 4. Replace the DC controller PCB

• Code: E004-0501
• Description: Fixing main thermistor, a connection error (circuit failure) of fixing subthermistor 1/2. Connection sensing signal of fixing main thermistor and sub thermistor 1/2 is not detected
• Remedy: 1. Check the connection of the connector on the fixing belt unit -> if it is disconnected, replace it 2. Faulty drawer connector -> clean the drawer or replace the fixing unit

• Code: E004-0502
• Description: Fixing belt temperature difference error 2. Difference of detected temperature between the fixing main thermistor (THM1-1) and the fixing subthermistor 1 (THM1-2) are bigger than the rated value.
• Remedy: 1. Fixing main /sub thermistor (THM1-1/2/3) connector disconnetion (pinching wire, broken wire) -> replace the fixing belt unit 2. Check the rotation of the fixing motor (to see if the connector is physically removed or disconnected) -> replace the fixing motor or the harness 3. Faulty drawer connector -> clean the drawer connector or replace the fixing unit 4. Replace the DC controller PCB

• Code: E004-0502
• Description: 1. Check the connection of the connector on the pressure thermistor -> if it is disconnected, replace the pressure stay 2. Faulty drawer connector -> clean the drawer or replace the fixing unit. sub thermistor 1/2 connection sensing signal is not detected
• Remedy: 1. Check the connection of the connector on the pressure thermistor -> if it is disconnected, replace the pressure stay 2. Faulty drawer connector -> clean the drawer or replace the fixing unit

• Code: E004-0503
• Description: Fixing belt temperature difference error 3. Difference of detected temperature between the fixing main thermistor (THM1-1) and the fixing subthermistor 2 (THM1-3) are bigger than the rated value
• Remedy: 1. Fixing main /sub thermistor (THM1-1/2/3) connector disconnetion (pinching wire, broken wire) -> replace the fixing belt unit 2. Check the rotation of the fixing motor (to see if the connector is physically removed or disconnected) -> replace the fixing motor or the harness 3. Faulty drawer connector -> clean the drawer connector or replace the fixing unit 4. Replace the DC controller PCB

• Code: E004-0504
• Description: Pressure belt temperature difference error. Difference of detected temperature between pressure subthermistor 2 (THM1-3) and pressure subthermistor 1 (THM1-2) is bigger than the rated value.
• Remedy: 1. The connectors of the pressure sub thermistor (THM3,4) are physically removed (the cable is caught, or disconnected) -> replace the thermistor or the presure stay 2. Soiled, improper location of, or faulty pressure sub thermistor (THM3,4) -> clean the thermistor or replace it 3. Faulty drawer connector is a possible cause -> clean the drawer connector or replace the fixing unit 4. Replace the DC controller PCB
