Trane TCP060F100AB Defrost Sensor Board
The defrost sensor board commences the defrost sequence in order to keep your outdoor unit from plugging up. The board is relayed information from a specific sensor located somewhere by the condenser to decide when to begin.
Simple signals your defrost board is not going to last much longer
- Self defrost sequence will not initiate especially when there is a rather large amount of frost built up
- The control board could signify an alphanumeric error code if the defrost board goes out
- The system may not work due to lack of airflow through the outdoor unit
