Goodman GMS90703BXA Defrost Sensor Board
The defrost sensor control board initiates the defrost cycle in order to continue normal heating and cooling operations. The control board relies on a sensor which is near the condenser somewhere, in order to determine when to initiate the defrosting cycle.
What are some indications that my outdoor defrost sensor board is on its last leg?
- Self defrost sequence will not initiate even though there is quite a bit frost that makes the unit run like crap
- The HVAC system control board could display an error of some type if the defrost board goes out
- Air conditioning may cease to function due to frost blocking the airflow outside
