Motor Test - All Configured Selections
This procedure tests every motor in the machine through the built-in test mode.
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.
- More than half the motors fail the full test: Do NOT replace individual motors. Investigate controller and main power distribution first.
- Burning smell during test: Stop test and remove power immediately.
- If more than half the motors fail the full test, do not replace individual motors; a qualified technician must investigate the controller and main power distribution.
- If a burning smell is detected during testing, stop immediately and call a qualified technician.

Where to find this
Use this as orientation before touching the machine. It is location help, not a repair instruction.
Start at the front door payment column; match the display, keypad, coin, bill, or card device to the symptom before opening deeper panels.
- Central microprocessor-based board that manages vend logic, motor control, refrigeration cycling, payment communication, and user interface.
- main logic board
- firmware chip
- connector headers
