VACUUM MOTOR TROUBLESHOOTING
WARNING!
Unplug the power cord before attempting any service to the machine.
Poor Vacuum Pickup Possible Causes:
•
Full filter bag
•
Debris blockage in vac shoe opening and hoses
•
Clogged vac secondary filter and exhaust filter
•
Holes/cracks in wand and hose
•
Broken brush belt
No Pick up - Vac Motor Stops Running:
•
Vacuum motor needs service (worn carbon brushes and bearings)
Note:
An internal thermo (heat sensing) over load device is built into the motor’s electrical windings. This opens (stops)
the circuit when the air flow needed for cooling is restricted. Try to determine the cause and correct it (troubleshoot the first
3 possible causes listed under poor vacuum pickup shown above). The thermo over load device will automatically reset
when the motor is allowed to cool.

BRUSH MOTOR TROUBLESHOOTING
WARNING!
Unplug the power cord before attempting any service to the machine.
Brush Motor Stops Running:
•
Debris wrapped around brush
•
Brush height adjustment knob not adjusted properly
•
Worn brush assembly bearings
Note Carpetwin 16XP Only:
An internal current sensing circuit board is wired into the brush motor to protect the motor
from both electrical and mechanical overloads. If an overload occurs and has caused the circuit protector to trip, unplug
the power cord and investigate possible causes listed above. When the cause of the original problem is determined and
corrected, reset the protector by turning the main switch OFF and then turning it back ON, this will automatically reset the
protector. If the overload protector trips repeatedly, contact your local Advance dealer for service.
