Product Will Not Vend - Dispensing Diagnostics
This procedure helps isolate mechanical or electrical failures preventing the product from dispensing correctly from the storage columns.
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.
- Multiple motors failed simultaneously: Suspect common cause: power supply, controller, or harness damage. Escalate to full system diagnosis.
- If multiple motors fail simultaneously, suspect a common cause like power supply or controller damage, requiring escalation to a qualified technician for full system diagnosis.
