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.

  • Evidence of electrical burning or arcing at any point: Stop immediately. Disconnect power. Hand off to licensed electrician or technician-advanced.
  • Repeated main fuse failure after replacement: Do not re-energize. Escalate to technician-advanced for short circuit investigation.
