Manuals from Dexter are also available for further troubleshooting assistance.
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 lit?
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-950, T-1200, T-1450 use 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 voltage is incorrect, replace transformer.
Check PCB board
Check all wire connections for sure contacts.
Check wiring
between 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 Lock
Mechanism
Check that 120 v power is at mechanism after start
button is pressed.
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
mechanism
Check to einsure that mechanism is receiving 120VAC
from main relay PCB. If it is, replace.
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
mechanism 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.
Door will not
open
Door Rod
Check to see that door rod from mechanism to lock
assembly is long enough to allow lock assembly to
disengage. If not, adjust rod.
Door locking
mechanism
Check that door lock mechanism is not stuck closed. If
stuck, replace.
