Reznor 210762 Limit Switch Automatic Reset: Eliminates manual interventionThe Reznor 210762 Limit Switch is a critical OEM replacement part engineered for precision thermal monitoring in waste oil heaters and HVAC systems. Specifically designed as a 155F CO Auto Limit Switch, this component functions as a low temperature limit switch or low oil limit thermostat, ensuring the heater operates within safe parameters. When the pre heater or combustion air reaches the 155F threshold, the normally closed (NC) contacts respond to
