Display, keypad, or selection problem Review
Dixie-Narco Narco Dn6g
Display, keypad, or selection problem Review
This advanced diagnostic sequence is designed for deeper troubleshooting, requiring a higher level of technical skill to safely navigate potential faults.
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.
- Because this flow involves advanced diagnostics, any suspected fault requires immediate escalation to a qualified technician.
- If the troubleshooting suggests an issue within the electrical system or refrigeration unit, a qualified technician must perform all subsequent checks.
