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.

  • Motor area produces burning smell during test vend: Unplug machine immediately. Mark column out of service. Technician required.
  • Repeated vend attempts cause machine controller to reset or display errors on other columns: Stop testing. Issue may be affecting other systems. Technician required.
  • Because this involves high-risk components, a qualified technician must diagnose the motor failure, particularly if burning smells are detected.
