Carrier 48XZ048090300 Defrost Sensor Board
The defrost sensor control board controls if and when to commence the defrost sequence which may be needed in order to defrost your outdoor unit. The defrost sensor board looks to a temperature sensor that can be found near the condenser, in order to decide when to begin.
Red flags the defrost sensor board is going out
- Your main control board might give out an alphanumeric error code if the defrost board fails
- The defrost feature never starts especially when there is a rather large amount of frost that makes the unit run like crap
- The system may stop running for the fact of the amount of frost on the outdoor unit
