Product Details

Description

This 3-inch High Limit Switch (L190-220F) is a vital safety component designed for residential furnaces and HVAC heating systems. Functioning as a thermal protection device, this limit control monitors the heat exchanger or plenum temperature to prevent the appliance from overheating. If internal temperatures reach the designated safety threshold—specifically the 220°F limit—the switch automatically interrupts the circuit to the burner or heating element. Once the system cools to the 190°F reset point, it allows the unit to resume operation. This high-quality replacement part features a 3-inch insertion probe for precise temperature sensing, ensuring your heating system operates safely and efficiently. It is a common fix for furnaces that are short-cycling or shutting down prematurely due to airflow or temperature issues.
