Symptom Probable Cause Suggested Remedy
Machine
does not
start
Power Supply
Check these areas: Circuit breakers, Voltage, Power leads,
Power connections. Is front display LED showing a dollar
amount.
Door Switch
Check for continuity through door switch when door is
closed. If no continuity, adjust or replace door switch.
Control Breaker or
Fuse
Check 1.5 amp (T-1200. uses 2.5amp) breaker or fuse for
continuity. If no continuity, replace breaker or fuse.
Control Trans-
former
Check voltage output from control transformer for 120VAC.
If voltage is incorrect, replace transformer.
Coin Acceptor
Check coin switch to make sure coins trip switch and give
continuity across switch when closed. If no continuity, adjust
or replace switch.
Check PCB board
Check all wire connections for sure contacts.
Check wiring be-
tween PCB
Check data cable phone type connectors unplug and VFD
and replug with power removed.
Check Relay PCB
Check all wire connections for sure contact.
Check Door Sole-
noid
Check that 120 v power is at solenoid after start button is
pushed.
Machine will
not accept
and count
coins
Coin Acceptor
Check coin acceptor switch for any type of blockage or dam-
age. Clean, adjust or replace the acceptor.
Power Supply
Check these areas: Circuit breakers, Voltage,Power leads,
Power connection
Door Closed Safety
Switch
Check door closed switch at door hinge for proper operation.
Door Handle

Main PCB
Replace
Door does
not lock
Check display for
fault code
Does F1 show on the front of display. If yes follow tests
described in fault code section.
Door locking sole-
noid
Check to insure that solenoid is receiving 120VAC from main
relay PCB. If it is, replace solenoid.
Door Switch
Check for continuity through door latch switch when door
closed. If no continuity, adjust or replace door switch.
Door will
not open
Thermoactuator
Check to see if thermoactuator(s) and/or its mechanism is
stuck or binding and not allowing the door lock solenoid to
open. Check to be sure that the locking thermoactuator is
not receiving 120VAC during the last 1 1/2 minutes of the
cycle. Also check to see that the unlocking thermoactuator
is receiving 120VAC during the last minute of the cycle. If
the thermoactuators do not receive voltage at the correct
times, change the timer. If the timing and voltage are cor-
rect, replace the thermoactuator.
