Machine Dead After Confirming External Power

This procedure systematically checks the entire power path, from the external connection point through internal protection devices to the main control unit.

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.

  • Immediately power down. Tag machine out of service. Escalate to manufacturer-or-licensed service.
  • If the issue persists after these checks, escalate to a qualified technician for advanced diagnostics, especially when measuring power supply outputs.
  • If the issue persists after these checks, escalate to a qualified technician for advanced diagnostics, especially when inspecting the main power entry components.

Location Help

Where to find this

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

Service zone 2

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

  • Receives facility power, distributes through fuse and power supply to internal systems.
  • Power cord
  • Main fuse
  • Power supply unit

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