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, scorch marks, or melted components found: Do not apply power. Disconnect from outlet. Tag out. Escalate to technician-advanced or manufacturer.
  • Water intrusion near electrical components: Do not apply power. Disconnect from outlet. Allow to dry completely. Inspect for corrosion before re-energizing.
  • If burning smell, scorch marks, or melted components are found, do not apply power; this requires a qualified technician.
  • If water intrusion is suspected near electrical components, do not apply power; this requires a qualified technician.
