Goodman ARUF364216 Defrost Sensor Board
The defrost sensor control board will determine when to initiate the defrost sequence which helps to get rid of the frost that collects on the outdoor unit. The control board is relayed information from a defrost sensor that can be found near the condenser, in order to agree when to initiate the defrosting cycle.
Red flags of a barely functioning AC defrost sensor board
- Defrost mode will not kick in despite the fact that there is quite a bit frost that makes the unit run like crap
- The whole system may stop running for the fact of frost blocking the airflow outside
- The primary control board may signify an error number when the defrost control board refuses to initialize properly
