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 or component damage.
  • Unknown voltage configuration.
  • Due to the presence of live-voltage checks and high-risk component replacements, this issue requires a qualified technician to safely diagnose and resolve the power loss.
  • Checking the main terminal block for voltage presence requires a qualified technician.

Location Help

Where to find this

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

Power Entry and Distribution

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

  • Safely routes main facility power to the machine power supply and isolates the unit for service.
  • Power cord
  • Main line switch
  • Line filter

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