Vend Motor Does Not Turn
Diagnoses why a vend motor fails to operate when a selection is made, starting with product loading checks and progressing to motor electrical diagnostics.
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: Likely a common-cause issue (controller, power supply, or main harness). Do not replace individual motors yet.
- Motor sparking or smoking during test: Unplug immediately. Motor may have internal short. Escalate to technician.
