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.

  • Repeatedly blown fuse: Stop replacing fuses. Full short-circuit diagnosis required by advanced technician.
  • Any burning smell or visible arcing: Immediately de-energize. Do not reapply power until cause is found and repaired.
  • If the machine fails to power on after initial checks, escalate this immediately to a qualified technician for a full short-circuit diagnosis.
  • Any work involving the main power input, fuses, or internal wiring must be performed by a qualified technician.
