Vend Motor Failure Diagnosis
This procedure guides you through diagnosing why a specific product selection fails to dispense, covering physical obstructions and motor performance issues.
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 failing simultaneously on the same shelf.: Stop and escalate to main harness or control board failure.
- If the issue persists after basic checks, the diagnosis requires advanced electrical testing; a qualified technician must assess the motor harness and control board connections.
