7-11 Centrifugal Switch Check
With an ohmmeter, place the the probes on
position 5 and 6 of the terminal board M1
(Figure 725 on the next page). The switch
should be closed when the motor is not
running. When the motor runs, the motor
draws high amps and the switch opens. If it
stays closed, it is stuck and the switch should
be repaired or replaced.
7-12 Pushbutton Checks
1) Contacts are marked NO = “Normally Open“
or NC = “Normally Closed”. Figure 726
shows continuity for a NC contact. If the
button is pressed it should open. A NO
switch operates in an opposite manner.
Pressing the button closes the switch and
creates continuity.
7-13 Control Box Check
1) Tighten the 4 socket head screws {Code
#33156, Pos. 37} that hold the control box to
the motor (Figure 727).
2) Check that the control box base is not
distorted or cracked especially at the junction
of the box to the motor. If damaged, it must
be replaced.
