Machine Completely Dead — Power Input Diagnostic

This diagnostic systematically checks the entire power path, starting from the wall outlet all the way to the machine's internal control board, to pinpoint where power loss is occurring.

Qualified technician handoff: stop before live electrical testing, sealed-system refrigeration work, compressor service, or protected-compartment access unless a qualified technician is handling the work.

Stop all work. Tag machine out of service. Escalate to supervisor and qualified electrician.
Immediately disconnect power. Tag machine out of service. Do not re-energize until cleared by qualified technician.
Because this involves checking power delivery and internal electrical connections, you must escalate to a qualified technician.
If power is not present after initial checks, a qualified technician must diagnose the main power input path.

Location Help

Where to find this

Use this as orientation before touching the machine. It is location help, not a repair instruction.

Power Input

Start outside the machine at the outlet and cord, then identify the power entry area before any protected-compartment inspection.

Delivers main line voltage to the machine and provides primary overcurrent protection.
Power cord or hardwire junction
Main fuse or circuit breaker
Line filter if equipped

Do not open energized or protected electrical areas unless a qualified technician or licensed electrician is handling the work.
