To avoid risk of electrical shock, personal injury or death, disconnect power to unit before servicing, unless testing
requires power.

• Thumping.  Check for loose tumbler baffle, rear

tumbler roller(s) worn or misaligned, out-of-round
tumbler or high weld seam on tumbler.

• Ticking.  Check for loose wire harness or object

caught in blower wheel area.

• Scraping.  Check for front or rear bulkhead

felt seal out of position or worn tumbler front
Rulon™ bearings.

• Popping or squealing sound.  Check for a sticky or

frayed belt.

If dryer will not heat (motor runs), check the following:

• Restricted exhaust caused by plastic or thin

foil flexible duct.

• Open heating element.
• Hi-Limit thermostat trips too soon or is open.
• Cycling thermostat trips too soon or is open.
• Temperature selector switch mis-wired or contacts

open.

• Timer functional.
• Cycle selector switch mis-wired or contacts open.
• Drive motor centrifugal start switch not allowing

voltage to gas valve or heating element.

If improper drying/clothes wrinkled/rough texture/taking
too long to dry, check the following:

• Restricted exhaust caused by plastic or thin foil

flexible duct.

• 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 makeup 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.

• Gas valve coil opens - weak point in coil opens

when stressed under heated conditions.

• Clothes too wet due to insufficient spin- out by

washer.

On time dry settings, check the following:

• Timer motor receiving proper voltage.
• Check timer motor connections.
• Timer functional.

If dryer will not start or run, check the following:

• All wires are hooked up to their corresponding

terminals.

• Dryer is plugged in.
• Blown fuse or circuit breaker.
• Door switch functional...door closed.
• Push-to-start switch functional.
• Timer functional...set in a cycle.
• Drive motor functional.
• Blown thermal fuse.

If drive motor runs, but the tumbler will not turn, check the
following:

• Belt off or broken/damaged.
• Idler tension spring too weak or stretched.
• Idler pulley jammed or stuck.

If dryer runs a few minutes and then stops - motor
overload protector opens, check the following:

• Lint buildup around drive motor.
• Low voltage present.
• Blower impeller blocked in blower housing.
• Drive motor - start switch contacts stuck closed.

If dryer blows fuses or trips circuit breaker, check the
following:

• The amperage readings are at 240 volts.  One line

will be 24 amps and other line will be 21 amps.
The neutral line will be at 4 amps.  If the above
amperages are present, then the house wiring,
fuse box or circuit breaker should be suspected.

• Shorted heating element to housing.
• Incorrect wiring or a wire shorting to ground.
• Drive motor winding shorting to ground.

• During ignition, the dryer will draw 7 amps.  With

the burner ON, the dryer will draw 4.5 amps.  If
the dryer is drawing amperages below this, then
the house wiring, fuse box or circuit breaker are
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.
