Product Not Dispensing - Vend Motor and Delivery Diagnostic
Determines whether a vend failure is mechanical, electrical, or sensor-related by checking product loading, motor response, and delivery confirmation.
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 selections failing simultaneously: Likely controller or main harness issue. Escalate to technician.
- Motor runs continuously without stopping: Disconnect power. Possible motor driver or sensor failure. Hand off.
