according to surrounding temperature.

• Check and replace

thermistor.

1) Check disconnected

Housing or severed 

Wire.

2) Check the resistance 

of thermistor.

3) Replace controller 

and then recheck, 
if anything else 
occurs.

resistance is less than 10Ω ?

After making damp clothes touch

sensor tips, the range are within

the below table in LQC test mode.

Check if they are working while being connected to power supply.

Is the product leveled?
(Check shaking / tilt )

Is it installed to Built In / Under 
environment? 

Is thermistor normal?

Is comp operation properly?
1) Power On
2) Display dataview mode
3) Comp on after 1min from start.
4) After comp on, check 
    corresponding the temp.
  -. Comp T : Is it rising?
  -. Eva in : Is it rising after falling? 

1. Is OLP normal?
2. Is Comp resistance normal?
3. Is capacitor resistance normal?
    (refer to page 16)
4. Is LEV resistance normal?
5. Check trace of oil leakage around 
    Comp.

2.For Comp defect
  -. Replace Comp
     (Refer to R code - C145 , Page 45)
3. For LEV defect
  -. Replace LEV.

Is thermistor resistance normal?
(Refer to resistance and 
measurement method, 
page 15~17)

Replace thermistor.

Improve dryer installation environment.
( Refer to installation environment, 
Page 10~12 )

Leg leveling
(Refer to how to adjust leveling, 
Page 10 )

Check Evaporator clogging status

( Refer to humidity sensor inspection 
method, Page 30 )

Does the defect occur after PCB 
replacement ?

Clean filter.
Clean Evaporator clogging.
(Refer to exploded view , Page 45)
