This diagnostic path is used to troubleshoot false error messages or failures in detecting when a product has successfully dropped into the collection area.
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.
- Sensor error persists after cleaning and harness check: Escalate to qualified technician for sensor replacement or controller diagnosis.
- If the sensor error persists after cleaning and harness checks, escalating to a qualified technician is required for sensor replacement or controller diagnosis.
