CEM3 Airflow Error
Symptoms/Issue
CEM3 is reporting an Airflow Error
Explanation of Issue
CEM3s do not have a built-in airflow sensor and cannot inherently self-report. It requires a code generated by an AF card within a Sensor rack. In the event an airflow error is thrown, the CEM3 is not suspect. One or more modules or any AF cards could be at fault
Corrosion can cause this issue
Fix/Solution
- Power off the Sensor rack and reseat modules
- Power on the rack and check if the error returns
- If error persists, a technician or electrician may be needed to inspect the rack for corrosion
