Will Not Run
Will not start or run:
• All wires are hooked up to their corresponding
terminals.
• Dryer is plugged in.
• Blown fuse or circuit breaker.
• Door switch functional...door closed. Check for
error code 3 (See Table for code definition).
• Start/Pause rotary selector dial functional.
• Control Board operational.
• Drive motor functional.
• Check motor winding resistance: 2.88ohms
between pin #3 and 4, 3.5ohms between pin #4
and 5.
Motor runs/ tumbler will not turn:
• Belt off or broken/damaged.
• Idler tension spring too weak or stretched.
• Idler pulley jammed or stuck.
Runs a few minutes and then stops:
• Lint buildup around drive motor.
• Low voltage present.
• Blower impeller blocked in blower
• housing.
• Drive motor - start switch contacts stuck closed.
Blows fuses or trips circuit breaker:
• The amperage readings are at 240 volts. One
line will be 24 amps and the other line will be 21
amps. The neutral line will be at 3 amps. If the
above amperages are present, then the house
wiring, fuse box or circuit breaker should be
suspect.
• Shorted heating element to housing.
• Incorrect wiring or a wire shorting to ground.
• Drive motor winding shorting to ground.
Gas Models
• During ignition the dryer will draw X amps. With the
burner ON, the dryer will draw X amps. If the dryer is
drawing amperages above this, then the house wiring,
fuse box or circuit breaker is suspected to be at fault.
• Igniter harness loose and shorted to base.
• Incorrect wiring or wire shorted to ground.
• Drive motor winding shorting to ground.
Will Not Dry
Will not heat (motor runs):
• Open heating element.
• Hi-Limit trips easily or is open.
• Regulating thermostat trips easily or is open.
• Membrane switch open.
• Check Thermistor.
Will Not Dry Gas Models
Poor Gas Ignition
When the dryer is operated on a heat setting, the igniter
should be energized and burner shall fire within 45
seconds at 120 VAC. The failure of a component in this
system will usually be indicated by one of three
symptoms:
The igniter does not glow. If the igniter does not heat
up, remove power and using an ohmmeter, check the
following:
• Open flame sensor
• Open igniter
• Shorted booster coil
• Open wiring
• Bad motor switch (Neutral supply)
• No power from control (L1 supply)
Igniter glows - No gas ignition. If the igniter heats up
but the main burner flame is not ignited, remove power
and using an ohmmeter, check the following:
• Open secondary coil
• Open holding coil
• Open wire harness
• Stuck flame sensor (Stuck closed)
The gas is ignited but the flame goes out. If a normal
ignition takes place and after a short while the flame
goes out, check for the following:
• Radiant sensor contacts opening
prematurely.
• Weak gas valve coil may open when
stressed by higher temperatures.
• Weak Hi-Limit
• Poor venting
• Bad drum seals
Improper drying/clothes wrinkled/ rough texture/long
dry time:
• Lint filter is not clean.
• Restriction in exhaust.
• Outside exhaust hood damper door stuck
closed.
• Exhaust too long, too many elbows, flex
ductwork installed.
• Poor intake air available for the dryer.
• Incorrect tumbler speed. Tumbler belt slipping.
• Blower impeller bound; check for foreign
material in blower area.
• Customer overloading dryer.
• Check clothing labels for fabric content and
cycle selected.
• Clothes too wet due to insufficient spin out by
washer.
