Amana-Goodman 10030912 Defrost Sensor The 143-82-021-02 is the currentThe Amana Goodman 10030912 Defrost Sensor is a critical OEM replacement part designed to maintain the thermal integrity of heating and cooling systems. Specifically engineered as an L55 25F bimetal thermostat, this sensor monitors the temperature of the evaporator coil to prevent excessive frost buildup that can lead to inefficient operation or compressor failure. By accurately sensing thermal thresholds, it initiates and terminates the defrost cycle,
