Fujitsu ASU9RMLQ Defrost Sensor Board
The defrost sensor board determines when to initiate the defrosting phase which helps to get rid of the frost that collects on the outdoor unit. The control board is relayed information from a sensor located near the condenser to decide when to begin.
Key symptoms of a failing defrost sensor board
- Self defrost sequence has not run for a while especially when there is frost that makes the unit run like crap
- Your main control board might give out a type of error code produced by too much frost
- Your system could not work for the fact of the safety issue that the frost poses
