So my CEM in my house light rack seems to have a bad air flow sensor.
Whenever you start up the rack it starts normally then the error message NO AIRFLOW is indicated.
Even though the fans are working properly.
The house light flicker on and off the minute the NO AIRFLOW Message comes up.
Even a reset will produce the same problem.
As of this morning the CEM has ceased working and I have no control over house lights at all.
So can you replace the air flow sensor in this?
If not what is a replacement for the old CEM classic now?
How much do they run?
Do you have to change our the main control head a s well?
