  1. 1

    Visual Check of Column and Product

    operator-intermediatelow

    With the machine powered on and door open, safely simulate a vend cycle. Observe the product column for any physical jams or misalignment preventing the product from falling.

    Expected: Product dispenses or jam location is identified.

    Evidence to note: photo

  2. 2

    Clear Product Jam

    operator-intermediatelow

    Carefully remove the jammed product and ensure the dispensing mechanism is free to rotate.

    Expected: Mechanism operates freely without obstruction.

    Evidence to note: note

  3. 3

    Check Motor Voltage

    technician-advancedlive-voltage

    Check for voltage at the vend motor connector when a selection is made. Requires safe electrical measurement practices.

    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.

    Expected: Voltage consistent with motor rating is present during vend cycle.

    Evidence to note: meter-reading

  4. 4

    Verify Motor Shaft Rotation

    operator-intermediatelow

    If voltage is present, observe if the motor shaft or dispensing cam rotates.

    Expected: Motor rotates and actuates the vend mechanism.

    Evidence to note: meter-reading

  5. 5

    Inspect Harness Continuity

    operator-intermediatehigh

    Verify continuity of the harness between the control/switch area and the vend motor.

    Expected: Wires have continuity, no open circuits.

    Evidence to note: meter-reading

  6. 6

    Replace Vend Motor

    operator-intermediatemedium

    Remove the defective motor and install a compatible replacement. Verify function.

    Expected: New motor operates correctly.

    Evidence to note: note

  7. 7

    Vend Cycle Restored

    operator-intermediatelow

    Close machine and return to service.

    Expected: Machine vends normally.

    Evidence to note: note

  8. 8

    Escalate to Advanced Repair

    operator-intermediatelow

    Stop and hand off to senior technician or manufacturer support.
