Disassembly and Reassembly _ 25
Part Figure Description
Replacement of the
main PCB
Check Points for Troubleshooting
1. Check whether there is any error in applying the power.
2. Check the voltage between the DC 5V and GND terminals.
3. If an error occurs when there is no characteristic error in the electric harnesses, check
these points:
3E error: The resistance of motor(U-V/V-W/W-U) is 4.8
HE/HE1 error: The resistance of heater(for 2000W unit) is 25.19 to 27.84
DE1 error: The resistance of door switch is 500 to 1,500
HE/HE1 error: The resistance of thermostat is 0
5E error: The resistance of drain motor is 148.5 to 181.5
4E error: The resistance of water valve is 4.4 k
Reassembly is in the reverse order of the removal.
