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.

  • Main input voltage absent at the noise filter output: Stop and escalate to advanced electrical diagnosis
  • If the main input voltage is absent at the noise filter output, immediately stop and escalate this issue to a qualified technician for advanced electrical diagnosis.
  • If fuse or breaker inspection reveals an issue, a qualified technician must assess the power distribution components.
  • If the issue persists after basic checks, a qualified technician must be called to safely diagnose the power 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 and Distribution

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

  • Supplies and distributes main AC power to the machine components.
  • Power cord
  • Noise filter
  • Main fuse or breaker

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