Figure 1. Specification Decal
Obtain the model number, serial number, voltage and phase
from the customer to prepare for the service call.
Date of installation.
Obtain the service history of the disposer.
Make sure the customer has tried resetting the overload pro-
tector and has checked for foreign objects jammed in the
grind chamber (see "Troubleshooting" on page 25).
Before troubleshooting for mechanical problems, determine if
the problem is electrical:
• To determine if the problem is in the switch or the dispos-
er, 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
corresponding 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.
