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.

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.
