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 from compressor area: Unplug immediately. Do not restart. Escalate to technician-advanced.
  • Visible refrigerant oil leak: Sealed-system breach suspected. Do not operate. Escalate to manufacturer-or-licensed technician.
  • Compressor drawing excessive current or tripping breaker: Stop testing. Escalate to licensed technician for compressor electrical and sealed-system evaluation.
  • If the issue involves the compressor or sealed refrigeration components, a qualified technician must perform the evaluation.
