Suggested Remedy
Check these areas: Circuit breakers,
Voltage, Power leads, Power connections. Is
front display lit?
Check for continuity through door switch
when door is closed. If no continuity, adjust
or replace door switch.
Check the 1.5 amp and 2.0 amp fuses (60
hz models) or circuit breaker (50 hz models)
for continuity. If no continuity, replace fuse
or breaker.
Check voltage output from control
transformer for 24 VAC and 120VAC (50 hz
models have 24 VAC only). If voltage is
incorrect, check for proper transformer tap
connection or replace transformer.
Check all wire connections for sure contacts.
Check data cable phone type connectors:
unplug and replug with power removed.
Check that 120 VAC power (for 60 hz) or 24
VAC power (for 50 hz) is at door lock motor
after start button is pressed.
Follow tests described in fault code section.
Check to ensure that mechanism is
receiving 120VAC for 60 hz models (or
24VAC for 50 hz models) from main relay
PCB. If it is receiving power but not
functioning, then replace mechanism.
Check for continuity through door latch
