Machine Completely Dead Diagnostic Flow

This flow helps determine if the machine has any power reaching it, checking everything from the facility outlet inward to the machine's main power input.

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.

  • Line voltage measured on terminal block but no low-voltage output from power supply: escalate_to_technician_advanced
  • Burning smell or scorch marks detected anywhere: stop_and_disconnect_power
  • Water intrusion near electrical components: stop_and_disconnect_power
  • If line voltage is measured at the terminal block but no low-voltage output is present, you must escalate this to a qualified technician.

    operator-intermediatelive-voltage

    Use a known-good lamp or outlet tester to confirm the wall outlet provides power.

    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 conditions
    • If line voltage is measured at the terminal block but no low-voltage output is present, you must escalate this to a qualified technician.
    • If a burning smell or scorch marks are detected anywhere, immediately stop and disconnect all power; this requires a qualified technician.
    • If water intrusion is observed near electrical components, stop immediately and disconnect power; this requires a qualified technician.

    Expected: Initial condition is documented before deeper diagnosis.
