DeLonghi WE110 Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrost cycle in order to keep your outdoor unit from plugging up. The defrost board relies on a sensor located in the outdoor unit to make the decision on when the defrost cycle should begin.
Red flags of a laboring defrost board
- The defrost sequence does not begin despite the fact that there is a lot of frost that has built up
- AC and heating system could not run due to the fact of frost blocking the airflow outside
- The control board may issue an error of some type produced by a failing defrost board
