TROUBLE SHOOTING
A WARNING
To avoid risk of electrical shock, personal injury or death; disconnect power to dryer before
servicing, unless testing requires power.
No Problem
Recommended Checks/Procedures
1
Will Not Start or Run
•
Check power to the machine.
•
Dryer is plugged in.
•
Blown fuse or circuit breaker.
•
Door switch functional...door closed. Check for error code 3 (See
Table for codedefinition).
•
Start/Pause rotary selector dial functional.
•
Control Board operational.
•
Belt off or broken and Belt Cut-off Switch operates.
•
Drive motor functional.
•
Check motor winding resistance: 2.88ohms between pin #3 and
4 ,3.5ohms between pin #4 and 5.
2
Motor runs/ tumbler
will not turn
•
Belt off or broken/damaged.
•
Idler tension spring too weak or stretched.
•
Idler pulley jammed or stuck.
3
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.
4
Blows fuses or trips
circuit breaker while
running(Elec. Model)
•
Read a amp.(if machine is drawing high current or if breaker is
weak, breaker/fuse rated too low, or wrong fuse installed)
•
Is the belt connected well?
•
Is the winding of the motor continuous?
(Rotor winding, stator winding, generator)
•
Is the motor protector normal?
•
If above points are not found, the PCB assembly is out of order.
Replace it.
5
Blows fuses or trips
circuit breaker while
running(Gas Model)
•
If the dryer is drawing more amperage than it is suppose to,
then the dryer is at fault. If the breaker is tripping or fuse is
blowing and the dryer is drawing the correct amperage, then
the problem is in the house electrical system.
•
Igniter harness loose and shorted to base.
•
Incorrect wiring or wire shorted to ground.
•
Drive motor winding shorting to ground.
6
Will not heat (motor
runs)
Open heating element.
•
Regulating thermostat trips easily or is open.
•
Check Thermistor.
7
Will Not Dry
Gas Model
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:
