International Comfort Products T8MPN100F14B1 Defrost Sensor Board
The defrost sensor control board determines when to initiate an important defrosting cycle which may be needed in order to get rid of the frost that collects on the outdoor unit. It depends on a temperature sensor that can be found near the condenser, in order to make the decision on when the defrost cycle should begin.
How can I tell if my AC defrost sensor board is failing?
- The main circuit board may throw an error signal when a defrost board fails to initialize
- The defrost sequence never begins even though there is a large amount of frost on the outdoor unit
- The HVAC system could cease to operate because of frost blocking the airflow outside
