Vend Motor Does Not Turn
This procedure helps determine if the inability to dispense a product is due to the motor itself, the connecting wiring, the signal from the control board, or a physical obstruction.
- Stop individual motor testing. Investigate common power feed and controller output. Escalate.
- If the motor does not respond to a command signal, a qualified technician should investigate the motor drive signal and controller output.
- If the motor appears electrically sound but fails to operate, a qualified technician must examine the motor harness connection.
