International Comfort Products N8MPL125J20A1 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrosting phase which aids to rid your unit of frost that can build up. The defrost board relies on a defrost sensor that can be found near the condenser, in order to agree when the defrost cycle should begin.
Warnings your defrost board needs replacing ASAP
- The main board may show a specific error code referring to a bad defrost board
- Your system could end up not running due to lack of airflow through the outdoor unit
- Defrost mode does not begin even though there is a lot of frost in the way
