Nordyne 626491R Defrost Sensor

The Nordyne 626491R Defrost Sensor is a vital component in Nordyne HVAC equipment, specifically those with defrost cycles. Made of copper for optimal temperature detection, this sensor plays a key role in preventing ice buildup on the evaporator coil during defrosting. By monitoring the temperature and reaching a pre-set threshold, the sensor signals the system to initiate a defrost cycle, melting any accumulated ice and ensuring efficient operation. The sensor operates within a voltage range of 18-32VAC and has a frequency of 60Hz. Its compact size (appro x imately 6.25 x 4 x 1 Inch) and lightweight design (around 0.1 lb) make it easy to integrate within various HVAC systems. By maintaining optimal defrost cycles, the 626491R sensor safeguards efficient operation, prevents evaporator coil damage from ice buildup, and ultimately contributes to e x tended system lifespan.
