Machine Completely Dead — Power Input Diagnostic

This diagnostic verifies the entire power path, from the wall outlet back to the machine's internal components, to ensure electricity is reaching the control system.

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.

  • Lock out machine. Escalate to manufacturer service. Do not continue cycling fuses.
  • Tag out of service. Investigate hidden harness failure before re-energizing.
  • Because this involves checking live-voltage components, you must escalate this to a qualified technician.
  • For safety, any investigation involving the terminal block or low-voltage supply must be performed by a qualified technician.
