Product Details

Description

This 3-inch high limit switch is a vital safety component designed for residential furnaces and HVAC heating systems. Functioning as a thermal cutout, this sensor monitors the temperature within the heat exchanger to prevent the unit from overheating. The L160-40F configuration is engineered to automatically trip and break the electrical circuit when the internal temperature reaches 160°F, protecting your equipment from heat-related damage and ensuring safe operation. Once the system cools down by 40°F (to 120°F), the switch automatically resets to allow normal heating cycles to resume. This replacement limit control is an essential fix for furnaces experiencing short-cycling or failing to ignite due to a faulty safety sensor.
