Goodman GCH91155DX Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin an important defrosting cycle which actually helps to keep the outdoor unit free from frost build-up. The defrost sensor board is influenced by a temperature sensor located somewhere by the condenser to make the decision on when to begin.
What symptoms are present when the defrost sensor board is not working right?
- The defrost feature will not initiate despite that there is a large amount frost on the outdoor unit
- The HVAC system could stop working for the fact of lack of airflow through the outdoor unit
- The HVAC system control board may throw a type of error code if the defrost board goes out
