Fujitsu ASU30CLX1 Defrost Sensor Board
The defrost control board controls if and when to commence an important defrosting cycle which actually helps to continue normal heating and cooling operations. The defrost board relies on a sensor located near the condenser to ascertain when to begin.
What are some hints that my AC defrost sensor board has a need to be replaced?
- Defrost mode does not begin especially when there is frost that needs to be removed
- The whole system may stop functioning for the fact of way too much frost build-up
- The main board might issue an error code referring to a bad defrost board
