Delonghi C100 Defrost Sensor Board
The defrost sensor board determines when to initiate an important defrosting cycle which may be needed in order to keep the outdoor unit free from frost build-up. The board depends on a specific sensor that can be found near the condenser, in order to verify when to begin.
Hints your defrost board needs replacing
- Defrost mode never initiates despite that there is a large amount frost in the way
- The main board could signify an error code if the defrost control board fails
- The system will stop running due to frost blocking the airflow outside
