Solution
Check table on wiring diagram
for correct full load amperage
draw. Adjust overload accord-
ingly.
❏ Check supply voltage.
Supply voltage to contactor
should be +- 10% of name-
plate voltage.
❏ Check wire terminations
and connections. Tighten if
loose.
Check line and load side of
contactor. There should be less
than a 5 volt drop across the
contactor. If there is not,
replace the contactor. See
Replacing the Contactor
Troubleshooting section.
Check amp draw of circuit. If
it is under the rated setting,
replace the overload module.
See Replacing Overload
Modules, in the
Troubleshooting section.
