Samsung AVMWH040CA0 Defrost Sensor Board
The defrost sensor control board determines when or if to start an important defrosting cycle in order to defrost your outdoor unit. The defrost sensor board is relayed information from a defrost sensor that can be found near the condenser, in order to decide when to initiate the defrosting cycle.
Important hints the defrost sensor board needs to be replaced
- The AC may not operate due to way too much frost build-up
- The defrost sequence never runs even though there is quite a bit frost that needs to be removed
- The main control board may signify an error signal referring to a failing defrost control board
