Product Dispensing — Electrical Check
If the dispensing mechanism does not activate electrically when a vend is attempted, the fault is in the control wiring or the motor/solenoid itself.
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.
- Overheated connector
- Burning smell during vend cycle
- Repeated fuse blowing when vend attempted
- Any electrical check involving the dispensing motor, solenoid, or associated wiring requires a qualified technician to prevent electrical hazards.
