Full No-Vend Diagnostic
When no product dispenses from any column, a systematic check of the entire power delivery system, motor commands, and primary wiring connections is required.
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.
- Line voltage measured on low-voltage side: Stop immediately. Escalate to technician-advanced. Possible power supply failure routing line voltage incorrectly.
- Burning smell or visible damage: Disconnect power. Do not re-energize. Escalate to technician-advanced.
- If line voltage is measured on the low-voltage side, stop immediately and escalate to a qualified technician.
- If a burning smell or visible damage is present, disconnect power and escalate to a qualified technician.
