Carrier 48GS Defrost Sensor Board
The defrost sensor board initiates the defrost cycle if necessary, to continue normal heating and cooling operations. The defrost board relies on a temperature sensor located near the condenser to determine when to begin.
What signals that my AC defrost sensor board has to be replaced?
- The HVAC system control board could throw a specific error code if the defrost board goes out
- Your system could cease to function for the simple fact of the frost blocking the flow of air
- Self defrost sequence will not initiate despite the fact that there is a lot of frost on the outdoor unit

HVAC pros may charge higher prices than others so you could call around to acquire the best rate if you want to pay bottom dollar.
