Rheem-Ruud 47-21711-11 Limit Switch preventing premature component failure orThe Rheem Ruud 47 21711 11 Limit Switch is a critical safety component designed for precise thermal regulation in HVAC furnace systems. As a genuine OEM replacement part, this normally closed (SPST) switch is engineered to disrupt the burner circuit if internal plenum temperatures exceed safety thresholds. It features a fixed open temperature of 180F and a fixed close temperature of 160F, providing a 20F differential that prevents rapid cycling of the
