Solenoid(s)
Location:
The solenoids are located on the mounting plate
immediately beneath the hoppers.
Test Procedure:
1.
1.
Unplug the grinder.
2.
Check the voltage across the left or right sole-
noid coil terminals with a voltmeter when the
Off/On/Start switch is momentarily pressed to
the “START” (lower) position and released (hop-
per selector switch must be corresponding to
the suspect solenoid). Plug-in the grinder. The
indication must be 120 volts ac.
