Carrier 48XPN060115300 Defrost Sensor Board
The defrost sensor board controls when to launch an important defrosting cycle if necessary, to rid your unit of frost that can build up. The board relies on a defrost sensor that can be found near the condenser, in order to decide when to begin.
Major indications your Carrier defrost sensor board will die soon
- The HVAC system control board might issue an error code if the defrost board goes out
- The system may cease to operate due to way too much frost build-up
- Defrost mode never runs despite the fact that there is quite a bit frost built up
