Automatic Reset Logic: Eliminates manual resets by closing the circuit once temperatures drop to 150°F

Key Benefits Universal Compatibility: Engineered as a direct-fit manual knob for all Danfoss RA-2000 thermostatic radiator valve bodies

Precise Thermal Calibration: Specifically rated at 160°F to ensure accurate protection against flame rollout

A 440V capacitor like the 12078 is a technical upgrade and can safely replace a 370V unit of the same capacitance

The 143-82-021-02 is the current manufacturing designation used by Sensus for the Green/Black 6"-14" w

Amana-Goodman 10030912 Defrost Sensor Automatic Reset Logic: Eliminates manualThe 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,
