ELECTRICAL TROUBLESHOOTING (Continued)
PROBLEM--SPIN DRIVE NOT WORKING IN SPIN MODE.
Assuming (SSS) System Start Switch is on with 120 volts AC to control panel and all other functions
are working.
Verify all wires shown on the wiring diagram are correct and pull on wire terminals with approximately
3 lbs force to verify there are no loose terminal connections and/or no loose crimps between the wire
and the terminal. If problem persists, test as listed below.
Possible Cause
Spin Speed Pot
(SSP) set to zero
Spin Motor Switch
(SMS) is not on
Circuit Breaker is
Tripped (4 AMP)
Spin Drive Control
(SDC) is not working
Spin Drive motor is
bad
Spin drive control in
Torque mode
Checkout Procedure
A. Set (SSP) to 200 on the
control panel.
B. Turn (SMS) switch on
C. Reset Circiut Breaker on
right side of machine by above
the Control Panel. Push in if
tripped.
D. Check (SDS) L1 to L2 for
120 Volts AC
E. With the Selector switch in
spin and the spin pot set to
400RPM Check (SDC) A1 and
A2 for 90-120 Volts DC
F. Check spin motor
continuity
G. Check continuity of mode
selector switch.
Spin Motor works
Yes--end troubleshooting

(SDC) Remove wires to Terminals L1and
L2 and test betwen wires for 120V AC.
Yes--reconnect wires to board then go to
Step E. next
No--Verify Power to Circuit Breaker and SMS
and continuity of wires. Replace CB or SMS
if needed.
(SDC) Remove wires, test Terminals A1 to
A2 on the board for approx 90-120 V DC
Yes--reconnect wires and go to Step F. next
No--go to Step G.
Remove wires at Terminal Strip 1, Term 4 &
5 check 0 ohms across the black and white
wires from the motor. Reading 0 Ohms
Yes--end troubleshooting, spin drive should
run, if not, replace motor.
No--go to Step J.
Light on SDC next to SP should be ON. If
not, remove wires 41SDCMOD and
44SDCCOM from SDC control board.
Check continuity of wires, should read
0 ohms. Light next to SP is on?
No--Check continuity of STS switch,
replace if bad. (Machine was in Torque
mode)
Yes-- Light next to SP is on but machine
does not work. Reinstall wires, Go to
Step H. next
DISCONNECT POWER
