All Recorded Causes
Verify Before Replacing Parts
- Confirm the exact Luxaire model family and default context before acting on a generic code description.
- Verify airflow first, then confirm operating pressures and temperature relationship before adjusting charge, since the most likely cause listed above.
- Look for restrictions, iced coils, or dirty heat-transfer surfaces that can mimic a charge problem, and separately confirm the next candidate on the list.
- After the correction, run the system long enough to confirm the default fault does not return under normal load.
