Description
Pressure belt temperature difference error
Difference of detected temperature between pressure
sub thermistor 2 (THM4) and pressure sub thermistor 1
(THM3) is bigger than the rated value.
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 -> clean the thermistor or replace it
3. Faulty drawer connector is a possible cause -> clean
the drawer connector or replace the fixing drawer
cable
4. Replace the DC controller PCB
Thermistor temperature difference error
Difference of detected temperature between thermistors
is bigger than the specified value.
1. The connectors of the fixing main/sub thermistor
(THM1-1 to 3) are physically removed (the cable is
caught, or disconnected) -> replace the fixing belt unit
2. Check the rotation of the fixing motor (the connector
is physically removed or disconnected) -> replace the
fixing motor or the harness
3. The connectors of the pressure sub thermistor (THM2,
3, 4) are physically removed (the cable is caught, or
disconnected) -> replace the thermistor or the presure
stay
4. Disconnection, soiled, improper location of, or faulty
pressure sub thermistor -> clean the thermistor or
replace it
5. Faulty drawer connector -> clean the drawer connector
or replace the fixing drawer cable
6. Replace the DC controller PCB
IH overcurrent detection error
Detected an overcurrent on IH power supply board.
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
