Product Details

Description

This 3-inch high limit switch is a vital safety component for residential furnaces and forced-air heating systems. Designed to prevent the heat exchanger from overheating, this thermal cutout switch monitors internal temperatures and automatically interrupts the heating cycle if temperatures reach unsafe levels. It features a precise 330°F cutout point and a 300°F reset point, ensuring your HVAC equipment operates reliably and safely. If your furnace is short-cycling or failing to stay on, replacing a faulty high limit control is an essential step in restoring proper airflow and heat management to your home heating system.
