Description
The Rheem-Ruud 47-104990-05 Limit Switch is a thermal switching element designed to monitor and respond to temperature levels inside heating equipment assemblies. It opens at 160F with a 20F differential that allows reset once temperatures decline, supporting consistent cycling behavior. In HVAC systems it is fitted within furnaces and air handling units where it is positioned on heat-exposed sections to track internal operating conditions. The switch is integrated into the appliances internal circuit arrangement, coordinating electrical flow with temperature response during heating cycles in residential and light commercial setups.
