Carrier 38SYG036 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin the defrost sequence which actually helps to keep your outdoor unit from plugging up. The defrost board is influenced by a defrost sensor which is near the condenser somewhere, in order to verify when to initiate the defrosting cycle.
What warnings are present when my defrost sensor board is almost dead?
- The control board might give out a type of error code when encountering a problem
- Defrosting never runs even though there is quite a bit frost on the external unit
- Your system could stop working due in part to the safety issue that the frost poses
