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 specifications 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.
Allow 5 minute cooling period and reset overload
protector.
Test and replace overload protector. See "Overload
Protector" on page 16.
Test stator. See "Stator" on page 20. Inspect for
pinched (grounded/shorted) stator lead wires.
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.

page.
