GE AZ75E18EACM1 Defrost Sensor Board
The defrost sensor control board determines when to initiate the defrosting phase which may be needed in order to continue normal heating and cooling operations. The defrost board relies on a specific sensor located in the outdoor unit to determine when to initiate the defrosting cycle.
Key signs of a dying GE defrost sensor board
- Defrosting never initiates despite that there is a large amount frost on the unit
- The HVAC system could stop operating due to the fact of frost blocking the fins on the outside unit
- The main board could display an error signal produced by a failing defrost board
