Nordyne 626487R Limit Switch 140°F-190°F

The Nordyne 626487R Limit Switch is a secure control that is temperature-activated and is applied in HVAC systems to regulate the amount of heat and safeguard equipment. It closes at 190°F to cut off operation when the system reaches too high temperatures and opens at 140°F when temperatures drop, to prevent overheating. It is installed in the vicinity of heat exchangers, burners or other heat-generating elements in furnaces and rooftop units and is used to regulate the continuity of the circuit to fans or burners depending on temperature.
