Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Clot-time results drift / QC failure
HighSymptoms: ACT / APTT results shift, controls out of range, poor duplicate agreement.
Root cause: Test-chamber temperature out of the 37 C window, a plunger / flag-detection fault, or reagent-cartridge issues.
Temperature alert / will not reach 37 C
MediumSymptoms: "Temperature" alert, tests will not start.
Root cause: Test-well heater or temperature-sensor fault.
Error message stops the test
MediumSymptoms: Error message and priority alert on the display.
Root cause: A subsystem fault indexed in the Error Messages section of the operator's manual.
Bar-code scanner fault (optional LS1900 / LS2208)
LowSymptoms: Cartridge or sample barcodes will not scan.
Root cause: Scanner needs its defaults set, or a scanner / cable fault.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Results drift / QC fails
- Confirm the instrument is at 37 C and stable.
- Run fresh controls at both levels.
- Check the plunger / flag detection moves freely.
- Verify reagent cartridges are in date and stored correctly.
- Refer for service if QC still fails with good cartridges.
Symptom: Error message
- Note the exact message and priority.
- Look it up in the Error Messages section of the operator's manual.
- Power-cycle to clear transient faults.
- Follow the manual's action for that message.
- Contact Medtronic Technical Service if it persists.
