Fujitsu AOU24RLXFZ Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrost sequence which aids to rid your unit of frost that can build up. The board relies on a defrost sensor which is near the condenser somewhere, in order to verify when to initiate the defrosting cycle.
Important clues of a faulty defrost sensor board
- Defrost session does not begin even though there is quite a bit frost that needs to be removed
- Your HVAC system will stop operating due to the fact of the amount of frost on the outdoor unit
- The HVAC system control board may show an error signal referring to the failed defrost sequence
