International Comfort Products NTN3075HFA1 Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin the defrost cycle if necessary, to remove frost build-up that may accumulate. The control board depends on a temperature sensor that can be found near the condenser, in order to determine when to initiate the defrosting cycle.
Hints the defrost sensor board needs to be replaced
- The HVAC system control board might give out a type of error code when encountering a problem
- Defrosting never runs even though there is a lot of frost built up
- Most systems will stop functioning due to too much frost
