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 detected at any point during diagnosis: Immediately disconnect power. Do not continue diagnosis. Tag machine and escalate to qualified technician.
  • Relay contacts found welded or shorted during live test: Disconnect power immediately. Tag component. Replace with verified-compatible part only.
  • Evidence of sealed-system issue with all external causes ruled out: Stop all non-licensed work. Contact manufacturer-authorized refrigeration service.
  • If the issue persists after basic checks, service involving the refrigeration system requires a qualified technician.

    Visually inspect the door gasket seal for any visible tears or gaps around the perimeter.

    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.

    Stop conditions
    • If the issue persists after basic checks, service involving the refrigeration system requires a qualified technician.
    • If live electrical checks are necessary, only a qualified technician should proceed with testing the relay contacts or power components.
    • If sealed-system issues are suspected, contact a qualified technician authorized for refrigeration service immediately.

    Expected: Initial condition is documented before deeper diagnosis.
