White-rodgers 3l01-230 Snap Disc Limit Thermostat

Product Description

The WHITE-RODGERS 3l01-230 is an automatic-reset snap disc limit thermostat designed for temperature control and protection in HVAC systems and appliances. It operates with a fixed cut-in temperature of 190 degrees F and a fixed cut-out temperature of 230 degrees F, using an open-on-rise switch action to interrupt the circuit when a preset high-temperature threshold is reached. The 3/4-inch disc format fits standard appliance mounting locations. Licensed HVAC technicians and appliance service technicians are the primary installers of this component.

This snap disc limit thermostat is used in residential and light commercial HVAC equipment, furnaces, and appliances where automatic high-limit protection is required. The automatic reset function restores operation once the sensed temperature drops back below the cut-in threshold, making it suitable for systems that require self-resetting overheat protection without manual intervention. It belongs to the 3F/3L Snap Disc Fan Limits Automatic Temperature product family and corresponds to Therm-O-Disc type 60T11, style 610021.
