No power or dead display Review
This advanced diagnostic sequence is designed for deeper troubleshooting when initial checks do not resolve the operational issue.
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.
- Any troubleshooting involving internal electrical systems or refrigeration circuits must be handled exclusively by a qualified technician.
- If the issue points toward internal wiring or power components, immediate escalation to a qualified technician is mandatory for safety.
