Carrier 48XZN042090300 Defrost Sensor Board

What red flags are there that my Carrier defrost sensor board is not working properly?
- Air conditioning may cease to function due to the fact of lack of airflow through the outdoor unit
- The defrost feature does not begin even though there is quite a bit frost on the unit
