Carrier 38TSA036 Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrost cycle which may be necessary to continue normal heating and cooling operations. It is influenced by a temperature sensor which is near the condenser somewhere, in order to ascertain when the defrost cycle should begin.
Do you know if your outdoor defrost sensor board is about to stop working?
- The system may stop functioning for the fact of frost blocking the fins on the outside unit
- The HVAC system control board may show an alphanumeric error code referring to the failed defrost sequence
- Defrost mode never initiates especially when there is frost that makes the unit run like crap
