241148 - Miller 30K Ohm NTC Thermistor Sensor with 18-Inch Lead

Precise Thermal Monitoring for Miller Equipment

The Miller 241148 Thermistor is a specialized electronic component designed to monitor the operating temperature of specific Miller welding power sources. As a Negative Temperature Coefficient (NTC) device, its resistance decreases as the temperature rises, allowing the machine's control board to accurately read thermal conditions in real-time. This specific unit is calibrated to provide a resistance of 30,000 Ohms (30K Ohm) at a standard ambient temperature of 25 degrees Celsius. This precise calibration is essential for the logic circuits of the welder to interpret temperature data correctly and engage cooling fans or thermal shutdowns when necessary.

Constructed to meet the rigorous standards of industrial environments, this genuine Miller replacement part features an 18.00-inch lead. The extended lead length is designed to facilitate easy installation, allowing the sensor to be mounted on heat sinks or transformers while connecting back to the main control board without tension or the need for wire splicing. Using authentic OEM parts like the 241148 ensures that the dielectric strength and thermal response times match the original engineering specifications of the machine.

Maintenance professionals understand that accurate thermal feedback is vital for the longevity of power electronics. A drifting or failed thermistor can lead to nuisance tripping, where the machine shuts down prematurely, or catastrophic failure if the machine overheats without detection. By replacing a suspect sensor with this genuine Miller 241148 unit, you restore the factory-intended protection levels to your equipment. This component is typically found in inverter-based power sources and other advanced welding systems where active thermal management is required to maintain high duty cycles.

Whether you are performing a routine overhaul or troubleshooting a specific thermal error code, this thermistor provides the reliability expected from Miller Electric components. It is packaged individually and ready for installation. Please verify fitment with your specific machine's serial number or parts manual to ensure this 30K Ohm NTC sensor is the correct revision for your equipment.
