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 3
Ω
between connector
BL2- (White wire) and WH4-
(Brown wire)?
Measure while door is closed.

Is resistance below 3
Ω
between connector
BL2- (White wire) and WH4-
(Yellow wire)?
Measure while door is closed.
Is resistance below 3
Ω
between connector
WH4- (Yellow wire) and WH4-
(Brown wire)?
Is resistance below 1
Ω
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.)
