International Comfort Products T8DNL075F16A1 Defrost Sensor Board
The defrost sensor control board will determine when to initiate an important defrosting cycle which helps to get rid of the frost that collects on the outdoor unit. The defrost sensor board relies on a defrost sensor which is near the condenser somewhere, in order to verify when the defrost cycle should begin.
How can I tell if my AC defrost sensor board is on its last leg?
- Self defrost sequence has not run for quite some time despite the fact that there is a lot of frost on the unit
- Most systems will cease to operate at all because of the safety features installed
- The HVAC system control board could display an error number referring to the failed defrost sequence
