Unresponsive Machine Diagnostic

This diagnostic flow guides initial checks when the machine appears to have no power or is otherwise unresponsive, requiring careful attention to electrical safety.

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.

  • Burning smell detected
  • Physical damage to power cord exposing conductors
  • Because this diagnostic involves power sources, if the issue cannot be resolved by basic checks, a qualified technician must be called to inspect internal components.
  • If any electrical component inspection is required, only a qualified technician should proceed.
