Product Details

Description

The 3-inch High Limit Switch L190-30F is a critical safety component designed for residential and commercial furnace and HVAC systems. This thermal limit control monitors the internal temperature of your heating equipment, providing essential protection against overheating. Specifically engineered for precision, it is designed to trip and cut power to the burner or heating elements when internal temperatures reach 190 degrees Fahrenheit, and automatically resets when the temperature drops by 30 degrees. A malfunctioning limit switch can cause short-cycling or prevent your furnace from operating entirely, making this an essential replacement part for maintaining a safe and efficient heating system. This specific model features a narrow-profile design to meet strict manufacturer clearance and sensitivity requirements, ensuring reliable performance in high-efficiency forced-air systems.
