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.

  • Harness shows signs of melting, arcing, or burning: Disconnect power. Do not reconnect until harness is replaced and root cause identified.
  • If the harness shows signs of melting or arcing, do not reconnect power; a qualified technician must replace the entire harness and determine the root cause of the failure.
