TROUBLESHOOTING
Disconnect power before troubleshoot-
ing or servicing the disposer.
Troubleshooting problems other than
those listed in this section should be
performed by qualied service person-
nel. Any troubleshooting performed by
untrained personnel could result in elec-
trical shock or damage to the disposer.
DANGER
If the problem is electrical:
• To determine if the problem is in the switch or the disposer,
bypass all electrical starting and/or electrical controls and run
the disposer direct.
• Make sure the disposer electrical specications match the
electric power supply.
• Make sure the motor lead connections are correct for the cor-
resonding power supply and starting controls.
• Determine if there are electrical problems with other kitchen
appliances. This may indicate a problem in the building’s
electrical circuitry.
Problem Cause Solution
Disposer will not start but water runs. Overload protector tripped. Allow 5 minute cooling period and reset overload
protector.
Overload protector burned out;
open circuits.
Test and replace overload protector. See “Overload
Protector” on page 16.
Stator burned out;
open windings
Test stator. See “Stator” on page 20. Inspect for
pinched (grounded/shorted) stator lead wires.
Jammed rotating shredder. Turn the control to the OFF position and complete the
following steps:
1. Insert the dejamming bar (slot down) through
the sink opening. Place the slot over one end of
the raised bars found on the top of the rotating
shredder.
2. Using an adjustable wrench or a pipe wrench for
leverage, twist the dejamming bar back and forth
to free the jam. The rotating shredder should
move freely when the jam is released.
3. Remove all foreign matter that caused the stop-
page.
4. Allow the disposer to cool for 3-5 minutes after it
stops running. Press the red reset button to reset
the overload protector. Never strike the reset but-
ton with and object.
