Motor Test - Single Selection
VendnetUSA 3136 / 3137 / 3138 / 3139
Motor Test - Single Selection
This procedure tests an individual product selection motor using the machine's 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.
- Motor produces burning smell during test: Immediately remove power. Do not re-test. Motor has likely failed electrically.
- Multiple motors fail test in the same row: Suspect common harness or controller driver issue, not individual motors.
- If the motor produces a burning smell during testing, immediately remove power and contact a qualified technician.
- If multiple motors fail the test in the same row, a qualified technician must investigate the common harness or controller driver.
