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.

  • Burnt components or acrid smell detected upon opening cabinet.: Immediately unplug machine. Do not probe. Escalate to licensed electrician.
  • If you suspect an issue with the main power input, fuse integrity, or low-voltage power supply output, immediately contact a qualified technician.
  • For any work involving live-voltage components or sealed-system procedures, only a qualified technician should proceed.

Location Help

Where to find this

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

Power Input

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

  • Main AC power entry, line filter, and primary fuse protection.
  • Power cord
  • Line filter
  • Main fuse

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