Nordyne 624812R Defrost Thermistor Temperature Sensor

The Nordyne 624812R Defrost Temperature Sensor Thermistor is a small but vital component in Nordyne HVAC systems. It monitors temperatures during the defrost cycle by sensing changes in electrical resistance based on temperature fluctuations. This thermistor typically operates within a range of 40°C to 120°C (104°F to 248°F). The sensor itself is small, measuring roughly 0.5 to 1 inch in length and 0.1 to 0.2 inches thick. By precisely tracking temperature changes, the thermistor ensures efficient defrost cycles and prevents damage to your HVAC system by stopping the defrost cycle when the appropriate temperature is reached. This helps maintain optimal system function and efficiency.
