Vend Failure Diagnostics
This process helps pinpoint why a product is failing to dispense, checking everything from physical jams to the motor's operational status.
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.
- Motor is hot to touch or shows signs of overheating: Disconnect power to motor immediately. Do not attempt to operate until cause is identified.
- Multiple trays failing simultaneously: Likely controller or harness issue, not individual motors. Escalate diagnosis.
- If the motor is hot to touch or shows signs of overheating, immediately disconnect power and contact a qualified technician.
- If multiple trays are failing simultaneously, this points to a controller or harness issue, requiring a qualified technician.
