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 at any point: Immediately unplug and tag out. Escalate to licensed electrician.
  • Fuse blows twice after replacement: Do not attempt third fuse. Short circuit likely - escalate to advanced technician.
  • Visible water intrusion near power: Do not energize. Escalate to licensed electrician.
  • If the issue involves live-voltage checks or power entry points, a qualified technician must perform the assessment.
