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

(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.
• 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.
