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.)
Drum will not rotate; no fan will function; no heater will work.
Turn the dryer’s power off, then measure resistance.
Is resistance below 3Ω between connector
BL2- (White wire) and WH4-
(Brown wire)?
Measure while door is closed.
• Replace control.
(Relay check)
• Check controller
connector.
• Check if door frame
presses door switch
knob.
• Check door switch.
• Check harness
connection.
• Replace control.
(Relay check)
• Check controller
connector.
• Replace outlet
• Thermostat.
(Refer to
‘component’)
• Check Idler assembly.
• Drum belt cuts off
• Drum belt takes off
from Motor pulley.
• Replace Idler
switch.
Is resistance below 3Ω between connector
BL2-
(White wire) and WH4- (Yellow wire)?
Measure while door is closed.
Is resistance below 3Ω between connector
WH4-
(Yellow wire) and WH4-
(Brown wire)?
Is resistance below 1Ω between terminals
of outlet thermostat attached to blower housing?
Does idle switch attached to motor bracket
operate level by drum belt?
(Not operating Lever is normal.)
Is resistance below 1Ω between Idler switch
terminals?
• Check motor. (Refer to ‘motor diagram & check’)
• Check if control connector is contacted.
