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 information code occurs when there is no characteristic code in the electric
harnesses, check these information code:
3C : The resistance of motor(U-V/V-W/W-U) is 4.5 to 7.0 Ω
HC/HC1 : The resistance of heater(for 2000W unit) is 25.19 to 27.84 Ω
DC1 : The resistance of door switch is 500 to 1,500 Ω
DC3/DDC : The resistance of door switch is 31.57 to Ω 61.57
5C : The resistance of drain motor is 182 to 222 Ω
4C : The resistance of water valve is 3.6 to 4.4 kΩ
