Check these areas: Circuit breakers, Voltage, Power leads,
Power connections. Is front display LED showing a dollar
amount.
Check for continuity through door switch when door is
closed. If no continuity, adjust or replace door switch.
Check 1.5 amp (T-1200. uses 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.
