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.

  • If the troubleshooting requires accessing internal wiring or electrical components, a qualified technician must perform the work.
  • Any diagnosis requiring interaction with the main power supply or control circuitry must be handled by a qualified technician.
  • If the issue points to refrigeration system faults, only a qualified technician should investigate the sealed system.
  • For any steps involving internal components, especially those related to power or refrigeration, contact a qualified technician immediately.
