Trane THT02243 Defrost Sensor | Genuine OEM Replacement

Ensure your heat pump operates at peak performance during freezing temperatures with the Genuine Trane THT02243 Defrost Sensor. This factory-authorized thermistor is the critical component your system uses to monitor outdoor coil temperatures, ensuring timely defrost cycles that prevent ice buildup and protect your equipment from long-term damage.

When your sensor fails, your unit may stay in defrost mode too long or fail to defrost at all, leading to a complete freeze-up of the outdoor coil. Replacing your worn sensor with a Genuine Trane/American Standard part ensures the precise resistance readings required by your specific control board.
