CONTROL BOX ASSEMBLY. (CONT)
Use multimeter on low ohms scale and check continuity from the front of receptacle (1) to rear output
of each pin. Replace receptacle as described in removal a. through c. if no continuity is indicated on any pin.
Two different power switches may be found. One (old style) incorporates overload
heaters, the other (new style) does not.
Check overload heaters for damage. If overload heaters are damaged, replace an old style switch with
a new style switch.
Set power switch to off. With multimeter on high ohms scale, measure from receptacle (1) to input
terminals of the motor contactor (2). The meter should indicate an open circuit.
