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 Transformer Check voltage output from control transformer for 120VAC. If volt-
age 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 Solenoid 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 damage.
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 Closed
Switch
Check single door closed switch at left side of door handle to close
when handle is vertical.
Control Breaker or
fuse
Check 1.5 amp (T-1200 uses 2.5 amp) breaker or fuse for continuity.
If no continuity, replace breaker.
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
correct, replace the thermoactuator.
