Vend Failure Diagnosis
This process systematically checks the mechanical and electrical components responsible for product dispensing, from the jam check to motor function.
- Motor housing hot or burning smell: Stop; unplug motor harness; do not re-energize; hand off
- Harness connector melted or discolored: Stop; do not reconnect; hand off for harness repair
- If the motor housing shows signs of burning or the motor harness connector is damaged, service must be escalated to a qualified technician for electrical repair.
