Manuals from Dexter are also available for further troubleshooting assistance.
Check these areas: Circuit breakers, Voltage, Power
leads, Power connections. Is front display LED lit?
Check for continuity through door switch when door is
closed. If no continuity, adjust or replace door switch.
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.
Check voltage output from control transformer for
120VAC. If voltage is incorrect, replace transformer.
Check all wire connections for sure contacts.
Check data cable phone type connectors unplug and VFD
and replug with power removed.
Check all wire connections for sure contact.
Check Door Lock
Mechanism
Check that 120 v power is at mechanism after start
button is pressed.
Check display for
fault code
Does F1 show on the front of display? If yes, follow tests
described in fault code section.
Check to einsure that mechanism is receiving 120VAC
from main relay PCB. If it is, replace.
Check for continuity through door latch switch when door
closed. If no continuity, adjust or replace door switch.
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.
Check to see that door rod from mechanism to lock
assembly is long enough to allow lock assembly to
disengage. If not, adjust rod.
Check that door lock mechanism is not stuck closed. If
stuck, replace.
