International Comfort Products N8MPL075B12B1 Defrost Sensor Board

The defrost sensor board instructs the outdoor unit to begin the defrost cycle which aids to get rid of the frost that collects on the outdoor unit. The board looks to a temperature sensor located near the condenser to determine when to initiate the defrosting cycle.

What are some hints that my AC defrost sensor board is in need of replacing?

Self defrost sequence does not run even though there is excessive frost that makes the unit run like crap
Your HVAC system will stop operating due in part to the frost blocking the flow of air
The control board may show an alphanumeric error code if the defrost board goes out
