Carrier 38BYC024 Defrost Sensor Board
The defrost sensor control board controls if and when to commence an important defrosting cycle which may be needed in order to continue normal heating and cooling operations. The board is influenced by a temperature sensor located somewhere by the condenser to ascertain when to begin.
Key indicators that my AC defrost sensor board is almost going bad?
- The primary control board might issue an error signal if the defrost control board fails
- Defrost mode will not initiate even though there is quite a bit frost on the external unit
- The system may cease to operate due to the fact that there is too much frost
