Caution
Trouble Symptom
Measurement Condition
Before measuring resistance, be sure to turn Power off, and do voltage discharge.
(When discharging, contact the metal plug of Power cord with earth line.)
Door Opening is not sensed.(During operation, when opening Door, Drum motor and
Heater run continuously; Door Close is not sensed.
(Drum motor will not operate. Display will flash at 0.5 second intervals.)
After turning Dryer Power Off, measure resistance.
Check Controller.
Check Harness-linking connector.
Measure while Door is closed. Check if
resistance is below 250Ω between “WH3-
”
(White wire) and “RD3-
”(Black wire)
Connector WH3, RD3 after taking WH3, RD3
out from Controller.
NO
YES
• Door switch
Check (Refer to
Component
testing.)
Measure while Door is open. Check if
resistance is 300~60Ω between “WH3-
”
(White wire) and “RD3-
” (Black wire)
Connector WH3, RD3 after taking WH3, RD3
out from Controller.
YES
NO
• Check Lamp.
(When opening
Lamp, replace then
measure again.)
• Door switch
Check(Refer to
