Section 3 Troubleshooting
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the tumbler before servicing.
• Close gas shut-off valve to gas tumbler before servicing.
• Close steam valve to steam tumbler before servicing.
• Never start the tumbler with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the tumbler is properly grounded.

NOTE: If the motor only runs with the start switch pressed in, that means the centrifugal switch in the motor
is bad. Replace the motor.
Step Problem
If No, then
1
Is there voltage to the NC terminal of switch A?
If yes, continue to next step.
Correct wiring between L1 on TBI and switch A.
2
Is there voltage to COM terminal of switch A?
If yes, continue to next step.
Check for proper operation of switch A. Replace switch
A if necessary.
3
Is there voltage to COM terminal of the door switch?
If yes, continue to next step.
Correct wiring between door switch and switch A of the
rotary coin drop.
4
With the door closed, is there voltage to the N.O. terminal
of the door switch? If yes, continue to next step.
Check door switch for proper operation, replace if
necessary.
5
Is there voltage across the coil of the control relay (CR)?
If yes, continue to next step.
Correct wiring to the control relay.
6

7
Is there voltage to the input side of the start switch?
If yes, continue to next step.
Correct wiring between start switch and door switch.
8
With the start button pressed in, is there voltage to the
output side of the start button? If yes, continue to next step.
Replace start switch.
9
Is there voltage to terminal 1 of the control relay?
If yes, continue to next step.
Correct wiring to terminal 1 of the control relay.
10
Is there voltage to terminal 3 of the control relay? If yes,
continue to next step.
Check for proper operation. Replace control relay if
necessary.
11
Is there voltage to terminal 1 of the motor? If yes, continue
to next step.
Correct wiring between motor and start switch.
12
Does the motor run? If yes, continue to next step.
