Goodman GCVC90704CXAA Defrost Sensor Board
The defrost control board will determine when to initiate the defrosting phase which aids to keep the outdoor unit free from frost build-up. The defrost sensor board depends on a sensor that can be found near the condenser, in order to determine when the defrost cycle should begin.
Key indicators that my outdoor defrost sensor board is almost dead?
- The whole system may stop functioning for the fact of the frost blocking the flow of air
- Self defrost sequence never starts despite that there is a large amount frost on the external unit
- The primary control board may issue a specific error code produced by too much frost
