Vend Motor Does Not Respond to Selection
A customer selects a product, but the corresponding dispensing motor does not activate. This requires isolating the failure point between the selection input and the motor 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.
- Multiple motors fail simultaneously after a power surge or storm: Check controller board and power supply for surge damage before replacing individual motors.
- If the motor fails to activate after checking connections, a qualified technician must diagnose the motor, associated wiring, and controller logic to determine the root cause of the failure.

Stop conditions- If the motor fails to activate after checking connections, a qualified technician must diagnose the motor, associated wiring, and controller logic to determine the root cause of the failure.
Expected: Initial condition is documented before deeper diagnosis.
