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.

  • Exposure to line voltage or unexpected capacitor discharge during measurement.: Immediately stop work, secure the area, and escalate to licensed electrician or manufacturer support.
  • Because this procedure involves live-voltage testing, a qualified technician must perform the voltage measurement to ensure safe operation.
  • Checking motor harness continuity requires electrical knowledge; therefore, a qualified technician must perform this check.

Location Help

Where to find this

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

Split Door Compartments

Start at the affected product shelf or selection row; compare the tray, coil, and product path with a nearby working selection.

  • Individual product compartments with split doors that open sequentially during a vend cycle to allow product retrieval.
  • Split door hinges
  • Motor coupling arms
  • Affected shelf, spiral coil, product lane, and vend motor area

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