Fujitsu ASYA07LCC Service Instruction page 51

Does not operate at all (Operation Lamp and Timer Lamp do not light up)
[Check Point]
(1) Is the input power voltage from the exclusive circuit AC outlet normal?
(2) Is the AC plug inserted to the AC outlet securely and not loose?
(3) Does not connected cable do wrong wiring?
(4) Check if each connector is inserted securely.
